In recent years, smartphone displays have developed far more acronyms than ever before with each different one featuring a different kind of technology. AMOLED, LCD, LED, IPS, TFT, PLS, LTPS, LTPO...the list continues to grow.

As if the different available technologies weren"t enough, component and smartphone manufacturers adopt more and more glorified names like "Super Retina XDR" and "Dynamic AMOLED", which end up increasing the potential for confusion among consumers. So let"s take a look at some of these terms used in smartphone specification sheets and decipher them.

There are many display types used in smartphones: LCD, OLED, AMOLED, Super AMOLED, TFT, IPS and a few others that are less frequently found on smartphones nowadays, like TFT-LCD. One of the most frequently found on mid-to-high range phones now is IPS-LCD. But what do these all mean?

LCD means Liquid Crystal Display, and its name refers to the array of liquid crystals illuminated by a backlight, and their ubiquity and relatively low cost make them a popular choice for smartphones and many other devices.

LCDs also tend to perform quite well in direct sunlight, as the entire display is illuminated from behind, but does suffer from potentially less accurate colour representation than displays that don"t require a backlight.

Within smartphones, you have both TFT and IPS displays. TFT stands for Thin Film Transistor, an advanced version of LCD that uses an active matrix (like the AM in AMOLED). Active matrix means that each pixel is attached to a transistor and capacitor individually.

The main advantage of TFT is its relatively low production cost and increased contrast when compared to traditional LCDs. The disadvantage of TFT LCDs is higher energy demands than some other LCDs, less impressive viewing angles and colour reproduction. It"s for these reasons, and falling costs of alternative options, that TFTs are not commonly used in smartphones anymore.Affiliate offer

IPS technology (In-Plane Switching) solves the problem that the first generation of LCD displays experience, which adopts the TN (Twisted Nematic) technique: where colour distortion occurs when you view the display from the side - an effect that continues to crop up on cheaper smartphones and tablets.

The PLS (Plane to Line Switching) standard uses an acronym that is very similar to that of IPS, and is it any wonder that its basic operation is also similar in nature? The technology, developed by Samsung Display, has the same characteristics as IPS displays - good colour reproduction and viewing angles, but a lower contrast level compared to OLED and LCD/VA displays.

According to Samsung Display, PLS panels have a lower production cost, higher brightness rates, and even superior viewing angles when compared to their rival, LG Display"s IPS panels. Ultimately, whether a PLS or IPS panel is used, it boils down to the choice of the component supplier.

This is a very common question after "LED" TVs were launched, with the short answer simply being LCD. The technology used in a LED display is liquid crystal, the difference being LEDs generating the backlight.

One of the highlights from TV makers at the CES 2021 tradeshow, mini-LED technology seemed far removed from mobile devices until Apple announced the 2021 iPad Pro. As the name implies, the technique is based on the miniaturization of the LEDs that form the backlight of the screen — which still uses an LCD panel.

Despite the improvement in terms of contrast (and potentially brightness) over traditional LCD/LED displays, LCD/mini-LEDs still divide the screen into brightness zones — over 2,500 in the case of the iPad and 2021 "QNED" TVs from LG — compared to dozens or hundreds of zones in previous-generation FALD (full-array local dimming) displays, on which the LEDs are behind the LCD panel instead of the edges.

However, for even greater contrast control, done individually at each point on the screen, it is necessary to go to panels equipped with microLED technologies – still cost-prohibitive in 2021 – or OLED, which until recently were manufactured on a large scale only in sizes for smartphones or televisions.Affiliate offer

AMOLED stands for Active Matrix Organic Light-Emitting Diode. While this may sound complicated it actually isn"t. We already encountered the active matrix in TFT LCD technology, and OLED is simply a term for another thin-film display technology.

OLED is an organic material that, as the name implies, emits light when a current is passed through it. As opposed to LCD panels, which are back-lit, OLED displays are "always off" unless the individual pixels are electrified.

This means that OLED displays have much purer blacks and consume less energy when black or darker colours are displayed on-screen. However, lighter-coloured themes on AMOLED screens use considerably more power than an LCD using the same theme. OLED screens are also more expensive to produce than LCDs.

Because the black pixels are "off" in an OLED display, the contrast ratios are also higher compared to LCD screens. AMOLED displays have a very fast refresh rate too, but on the downside are not quite as visible in direct sunlight as backlit LCDs. Screen burn-in and diode degradation (because they are organic) are other factors to consider.Affiliate offer

OLED stands for Organic Light Emitting Diode. An OLED display is comprised of thin sheets of electroluminescent material, the main benefit of which is they produce their own light, and so don"t require a backlight, cutting down on energy requirements. OLED displays are more commonly referred to as AMOLED displays when used on smartphones or TVs.

As we"ve already covered, the AM part of AMOLED stands for Active Matrix, which is different from a Passive Matrix OLED (P-OLED), though these are less common in smartphones.

Super AMOLED is the name given by Samsung to its displays that used to only be found in high-end models but have now trickled down to more modestly specced devices. Like IPS LCDs, Super AMOLED improves upon the basic AMOLED premise by integrating the touch response layer into the display itself, rather than as an extra layer on top.

The latest evolution of the technology has been christened "Dynamic AMOLED". Samsung didn"t go into detail about what the term means, but highlighted that panels with such identification include HDR10+ certification that supports a wider range of contrast and colours, as well as blue light reduction for improved visual comfort.

The technology debuted with the obscure Royole FlexPai, equipped with an OLED panel supplied by China"s BOE, and was then used in the Huawei Mate X (pictured above) and the Motorola Razr (2019), where both also sport BOE"s panel - and the Galaxy Flip and Fold lines, using the component supplied by Samsung Display.Affiliate offer

Resolution describes the number of individual pixels (or points) displayed on the screen and is usually presented for phones by the number of horizontal pixels — vertical when referring to TVs and monitors. More pixels on the same display allow for more detailed images and clearer text.

To make it easier to compare different models, brands usually adopt the same naming scheme made popular by the TV market with terms like HD, FullHD and UltraHD. But with phones adopting a wide range of different screen proportions, just knowing that is not enough to know the total pixels displayed on the screen.Common phone resolutions

But resolution in itself is not a good measure for image clarity, for that we need to consider the display size, resulting in the pixel density by area measured by DPI/PPI (dots/points per inch).Affiliate offer

Speaking of pixel density, this was one of Apple"s highlights back in 2010 during the launch of the iPhone 4. The company christened the LCD screen (LED, TFT, and IPS) used in the smartphone as "Retina Display", thanks to the high resolution of the panel used (960 by 640 pixels back then) in its 3.5-inch display.

The name coined by Apple"s marketing department is applied to screens which, according to the company, the human eye is unable to discern the individual pixels from a normal viewing distance. In the case of iPhones, the term was applied to displays with a pixel density that is greater than 300 ppi (dots per inch).

Since then, other manufacturers have followed suit, adopting panels with increasingly higher resolutions. While the iPhone 12 mini offers 476 dpi, models like Sony Xperia 1 boast a whopping 643 dpi.

With the iPhone 11 Pro, another term was introduced to the equation: "Super Retina XDR". Still using an OLED panel (that is supplied by Samsung Display or LG Display), the smartphone brings even higher specs in terms of contrast - with a 2,000,000:1 ratio and brightness level of 1,200 nits, which have been specially optimized for displaying content in HDR format.

As a kind of consolation prize for iPhone XR and iPhone 11 buyers, who continued relying on LCD panels, Apple classified the display used in the smartphones with a new term, "Liquid Retina". This was later applied also to the iPad Pro and iPad Air models, with the name defining screens that boast a high range and colour accuracy, at least based on the company"s standards.

Nit, or candela per square meter in the international system (cd/m²), is a unit of measurement of luminance, i.e. the intensity of light emitted. In the case of smartphone screens and monitors in general, such a value defines just how bright the display is - the higher the value, the more intense the light emitted by the screen.

The result is smoother animations on the phone, both during regular use and in games, compared to screens that have a 60 Hz refresh rate which remains the standard rate in the market when it comes to displays.

Originally touted to be a "gimmick" in 2017, with the launch of the Razer Phone, the feature gained more and more momentum in due time, even with a corresponding decrease in battery life. In order to make the most of this feature, manufacturers began to adopt screens with variable refresh rates, which can be adjusted according to the content displayed - which is 24 fps in most movies, 30 or 60 fps in home video recordings, and so forth.

The same unit of measurement is used for the sampling rate. Although similar, the value here represents the number of times per second the screen is able to register touches. The higher the sample rate, the faster the smartphone registers such touches, which results in a faster response time.

To further muddy the alphabet soup that we"ve come across, you will also run into other less common terms that are often highlighted in promotional materials for smartphones.

TFT(Thin Film Transistor) - a type of LCD display that adopts a thin semiconductor layer deposited on the panel, which allows for active control of the colour intensity in each pixel, featuring a similar concept as that of active-matrix (AM) used in AMOLED displays. It is used in TN, IPS/PLS, VA/PVA/MVA panels, etc.

IGZO(Indium Gallium Zinc Oxide) - a semiconductor material used in TFT films, which also allows higher resolutions and lower power consumption, and sees action in different types of LCD screens (TN, IPS, VA) and OLED displays

LTPO(Low Temperature Polycrystaline Oxide) - a technology developed by Apple that can be used in both OLED and LCD displays, as it combines LTPS and IGZO techniques. The result? Lower power consumption. It has been used in the Apple Watch 4 and the Galaxy S21 Ultra.

LTPO allows the display to adjust its refresh rate, adapting dynamically to the content shown. Scrolling pages can trigger the fastest mode for a fluid viewing, while displaying a static image allows the phone to use a lower refresh rate, saving the battery.

In 2022, flagship phones started using the so-called LTPO 2.0 tech, whose main advantage is being able to go down to a 1 Hz refresh rate, instead of the 10 Hz available in first-generation LTPO panels. Found in phones like the OnePlus 10 Pro and the Galaxy S22 Ultra, LTPO 2.0 promises even further energy savings.

Among televisions, the long-standing featured technology has always been miniLED - which consists of increasing the number of lighting zones in the backlight while still using an LCD panel. There are whispers going around that smartphones and smartwatches will be looking at incorporating microLED technology in their devices soon, with it being radically different from LCD/LED displays as it sports similar image characteristics to that of OLEDs.

By adopting a self-emitting light technology, microLED displays do not require the use of a backlight, with each pixel being "turned off" individually. The result is impressive: your eyes see the same level of contrast as OLED displays, without suffering from the risk of image retention or burn-in of organic diodes.

Each technology has its own advantages and disadvantages but in recent years, OLED screens have gained prominence, especially with the adoption of the component in high-end flagship smartphones. It gained an even greater degree of popularity after the launch of the iPhone X, which cemented the position of OLED panels in the premium segment.

As previously stated, OLED/AMOLED screens have the advantage of a varied contrast level, resulting from individual brightness control for the pixels. Another result of this is the more realistic reproduction of black, as well as low power consumption when the screen shows off dark images - which has also helped to popularize dark modes on smartphones.

While that is a very real possibility, it is not something that affects most users, who often confuse burn-in with a similar problem - image retention, which is temporary and usually resolves itself after a few minutes.

In the case of LCD displays, the main advantage lies in the low manufacturing cost, with dozens of players in the market offering competitive pricing and a high production volume. Some brands have taken advantage of this feature to prioritize certain features - such as a higher refresh rate - instead of adopting an OLED panel, such as the Xiaomi Mi 10T.

Today, many of us rely on our smartphones to communicate, work, and play. Therefore, it can be quite alarming when they begin to act strangely – especially if you can’t get your phone to turn on at all.

One of the most concerning issues to plague smartphone users is a black screen, often referred to as the “black screen of death.” However, despite the harsh name, this issue can be remedied in several ways.

To fix a black screen on an iPhone or Android, the first (and easiest) step is to do a hard reset. This basically entails rebooting the phone’s software. A hard reset can be performed right on your phone, although the process differs depending on what type of device you own.

If you’re still staring at a blank screen, it’s possible that the cable connecting the logic board to the LCD screen has become disconnected. This can occur if you accidentally drop your phone a few times. In order to regain your screen’s functionality, the cable will need to be plugged back in.

If you want to repair a broken iPhone or Android this way, it’s best to seek help from a professional. While you may find DIY instructions online, you could risk causing irreparable damage to your device if you don’t know what you’re doing. So, if you suspect that your phone’s LCD cable is disconnected, search for a place in Las Vegas that fixes phones.

When your phone screen goes black randomly, it may be an indication that something is wrong with your operating system. In that case, a factory reset is often beneficial. During a factory reset, your device’s data and settings are completely wiped, returning the phone to its original state (i.e., the state it was in when you first purchased it).

Not sure how to do a factory reset on an iPhone or Android? The process is more involved than that of a hard reset but can still be done with moderate ease.

Keep in mind that this process takes longer than a simple hard reset – you may have to wait several minutes for your phone to restart. Once the process is complete, check to make sure the device has been restored to its factory settings. If you’re presented with the iOS Setup Assistant upon startup, you’ll know the reset was successful. From there, you can choose to restore your backed-up data.

Sometimes a power button can get stuck due to trapped gunk, debris, or sticky food. You can try to dislodge debris by pressing the button rapidly several times. In most cases, the most effective method for sticky buttons is applying a Q-tip with rubbing alcohol. Swab the area around the button to loosen up and extract dirt, dust, or whatever might be trapped in there. In some instances, you may have a broken button that will need to be repaired.

Your phone may not be charging properly if the charging port is blocked off due to grit or debris. Simply blowing on the port a few times can help. For a deeper clean, you can try gently scraping with a toothpick or using a cotton ball (or Q-tip) with rubbing alcohol. Some people recommend trying a low setting with a vacuum to extract dirt, but that can easily damage parts. Blowing out dirt with compressed air is a safer alternative.

Software issues with apps can sometimes cause a phone to act unpredictably. If you are noticing certain apps are crashing frequently, you should update them immediately. You should also consider deleting buggy apps for security and the health of your phone. If an app has crashed on your Android, you can force stop it through settings > apps & notifications -> see all apps -> force stop.

OLED displays have become increasingly common and accessible over the past few years. While they were once reserved for premium smartphones, you’ll now find OLED displays at every smartphone price point. Not every OLED display is equal, though – differences in materials and manufacturing processes can result in varying display qualities. In that vein, let’s explore the differences between POLED vs AMOLED, and what these acronyms mean in the real world.

If you look at an OLED display under a microscope, you’ll see these diodes arranged in various red, green, and blue configurations in order to produce a full range of colors. OLED has a key advantage over conventional LCDs – individual light emitters can be switched completely off. This gives OLED deep blacks and an excellent contrast ratio.

Naturally, light emitters in an OLED display need a power source in order to function. Manufacturers can use either a passive wiring matrix or an active wiring matrix. Passive matrix displays provide current to an entire row of LEDs, which isn’t ideal but it is cheap. An active matrix, on the other hand, introduces a capacitor and thin-film transistor (TFT) network that allows each pixel to be driven individually. This driving matrix is part of the panel that sits on top of a base substrate.

AMOLED simply refers to an Active Matrix OLED panel. The AMOLED branding has become synonymous with Samsung Display’s OLED panels over the years. However, all smartphone OLED panels, including those from Samsung’s rivals like LG Display use active-matrix technology too – they just aren’t marketed as such.

In case you’re wondering what Super AMOLED means, it’s another bit of branding to indicate the presence of an embedded touch-sensitive layer. Similarly, Dynamic AMOLED refers to a display with HDR capabilities, specifically support for Samsung’s favored HDR10+ standard.

Now that we know the layered structure of an OLED display, we can move on to the plastic part. While the first wave of OLED panels was built using glass substrates, the desire for more interesting form factors has seen manufacturers use more flexible plastic components. This is where the P in POLED comes from.

Glass is fixed and rigid, while plastic substrates can be more easily formed into new shapes. This property is absolutely essential for curved screens as well as foldable devices like Samsung’s Galaxy Fold series. Working with plastics is also much more cost-effective than glass.

Manufacturers have experimented with a range of plastics for flexible displays, including polyethylene terephthalate (PET) and polyethylene naphthalate (PEN). OLED manufacturers have settled on using polyimide plastics (PI) that can better withstand high TFT manufacturing temperatures. The type of substrate and heating process used also defines the flexibility of the display.

The somewhat confusing part is that Samsung’s AMOLED displays use plastic substrates. And as the name suggests, LG Display’s POLED technology clearly uses plastic as well. In summary, it’s absolutely possible to build a plastic substrate, active-matrix OLED panel. That’s exactly what both of the big two panel manufacturers are doing when it comes to mobile displays.

Even though LG and Samsung-made OLED panels qualify as both POLED and AMOLED simultaneously, the companies aren’t exactly producing identical panels. The quality of the TFT layer and plastic compound can make a difference to display performance, as can the type of emitters and sub-pixel layout.

Different color LEDs offer different brightnesses and shelf life. Blue emitters, for example, degrade the quickest. Panel manufacturers can therefore opt to use different LED materials – such as small-molecule, polymer, or phosphorescent – to optimize their designs. This may also necessitate different subpixel layouts in order to balance the panel white color, gamut, and resolution.

Over the years, we’ve seen OLED display manufacturers converge on a set of standard parameters. For example, both LG and Samsung use a diamond PenTile sub-pixel layout for smartphone displays. This just means that both should offer similar long-term reliability.

Even when it comes to other attributes like power consumption, brightness, low brightness performance, and panel uniformity, it’s unclear if one has an upper hand. That said, most smartphone makers — from Apple to OnePlus — turn to Samsung’s AMOLED panels for their flagship devices.

In the past, LG used POLED displays in its own flagship smartphones like the Velvet and Wing. However, these panels fell slightly short of the competition in certain aspects like peak brightness and color gamut coverage. These shortfalls led to speculations that Samsung has a leg up over the competition, but the accuracy of these claims is anyone’s guess.

So does that mean you should avoid POLED? Not quite — it’s still fundamentally OLED technology, which offers numerous advantages over IPS LCD. Moreover, you’ll mostly find POLED displays in mid-range and budget smartphones these days, where they should have no problem matching Samsung’s own lower-end AMOLED panels. As a relatively smaller player, LG may also offer more competitive pricing as compared to Samsung.

For most consumers, the choice of POLED vs AMOLED will be of little consequence. The underlying principle – an active-matrix OLED on a flexible plastic substrate – applies equally to both, after all. Despite the different names, LG Display and Samsung aren’t worlds apart in their approach to producing OLED panels for smartphones.

If you spend long enough debating the merits of LCD vs. OLED display technologies, eventually, someone will touch upon the subject of the dreaded OLED screen burn in. The point made is that OLED displays will inevitably suffer from horrible-looking artifacts over time, while LCD and new technologies like Mini-LED won’t. But like most of these debates, you’ll probably hear as many overblown anecdotes as you will actual facts about the issue.

You may never have experienced it for yourself, but many consumers are wary about the possibility of burn in when pondering their next smartphone purchase. Particularly as expensive flagship smartphones have universally adopted OLED display technology. Apple, Google, and other manufacturers acknowledge that burn in can be a problem in rare cases. OLED technology has made its way to much more affordable price points in recent years, putting the issue on the radar for even more consumers.

The word “burn in” is a little misleading, as no actual burning or heat problems are involved. Instead, this term describes a display suffering from permanent discoloration across any part of the panel. This may take the form of a text or image outline, fading of colors, or other noticeable patches and patterns on display. The display still works as expected, but a somewhat noticeable ghost image or discoloration persists when the screen is on. To be considered screen burn in, these artifacts have to be permanent and are a defect caused on the display hardware side. Rather than a graphical glitch that may be caused by software, temporary image retention, or a problem with the display driver circuitry.

The term dates back to old CRT monitors, where phosphor compounds that emit light to produce images lost their luminance with time. LCD panels can exhibit similar problems, but these are much rarer due to the nature of LCD’s backlight and color matrix design.

Although not as bad or noticeable as old CRT issues, today’s OLED smartphone displays can eventually suffer from a similar problem. That being said, it’s pretty difficult and rare to notice unless you know what you’re looking for, and it takes hundreds, if not thousands, of hours of screen-on time before any such errors appear. In smartphones, pattern burn in is typically associated with always-on displays, navigation buttons, and the notification bar. The example below demonstrates a textbook case:

Although most smartphones now support gesture navigation controls in the place of the old button design. So this type of burn-in is much less of a problem than it used to be.

The cause of all screen burn in is the varying lifecycle of a display’s light-producing components. As these parts age, their brightness changes, and therefore the panel’s color reproduction gradually shifts with time. Although this can be mitigated somewhat with clever software, all displays experience some color shift as they age. But with burn in, some parts of the screen age faster than others. This can gradually shift the perceivable colors of the screen in one area more than in another, leaving what looks like a ghost image behind.

With modern smartphone and smartwatch technology, screen burn in can manifest due to the different life spans between the red, green, and blue LED subpixels used in OLED panels. As we mentioned before, areas of the display that seldom change, are bright white, or are often black and switched off, such as navigation buttons or the notification bar, are the most likely areas to notice this issue. You may also notice the effect in darkened status bars designed to hide display notches.

So, if one part of the panel spends a lot of time displaying a blue or white image, the blue pixels in this area will degrade faster than in other areas. That’s essentially what burn in is. However, display manufacturers do account for this in their panel designs.

If OLED screens have a problem with burn in, why do we continue using them? Burn in is a true downside to OLED displays, but there are plenty of reasons consumers and manufacturers like them. For starters, image quality is much better than in LCDs. OLED panels can reproduce more vibrant colors, more contrast, wider viewing angles, and faster refresh rates. Colors tend to be much more saturated, and blacks are much darker.

OLED displays have a simpler design, allowing thinner, lighter smartphone designs. You can also thank OLED technology for foldable phones and curved displays. If those improvements weren’t enough, you’ll also enjoy lower power consumption with OLED.

Additionally, burn in problems are only common after prolonged periods of use. As you may already know, smartphone manufacturers don’t expect you to keep a smartphone for more than 2-3 years. Recent statistics show that consumers currently keep their phones for an average of 2.75 years.

At this stage, manufacturers are very aware of the potential issues and have already taken some intelligent steps to help avoid burn in. For starters, Samsung has been using its pentile subpixel arrangement in its AMOLED displays since the Galaxy S3. By making the blue subpixel larger, it requires less current to drive in order to provide the necessary light. Driving the LED with less current increases its lifespan, so it takes longer for any noticeable color shift to occur.

This doesn’t directly address the issue of different parts of the screen aging at different rates, but it does mean that it will take significantly longer to notice than with older or cheaper OLED panels. More expensive and modern OLED panels are built with longer-lasting LEDs and well-designed layouts, meaning flagship smartphone displays age slower. These days, it’s cheaper phones packing cheaper displays that are marginally more likely to see issues after heavy use.

There are software solutions too. Android Wear product manufacturers can enable the OS’s “burn protection” option. This mode periodically shifts the screen’s contents by a few pixels, so they spend equal time displaying different colors. Smartphones equipped with Always-On display technology employ a similar tactic. Google also suggests a selection of design guidelines tailored to avoid screen burn-in problems when designing OLED watches. The move towards gesture rather than on-screen navigation controls is also helping to alleviate one of the more noticeable burn in areas.

Try to make it so that the screen isn’t displaying the same thing all the time, in the same areas of the screen. For example, if you have a widget that almost always looks the same, chances are it will eventually burn into the image. Move things around now and then, and try to keep the view of your phone dynamic.

All that said, screen burn in isn’t something that should concern many users if they’re looking to buy a new OLED smartphone. Modern panels have much longer lifespans than early OLED smartphones, and even then, burn in was rare. Just don’t leave a static image on the screen 24/7 with the brightness set at max.

The bottom line is that you should be looking at several years’ worth of use out of a modern smartphone display before any screen burn in will be noticeable. But it doesn’t hurt to be aware of what can happen to aging handsets and how to maximize their lifespan.

Samsung has a phone for sale at just about every price point. While this has worked out very well for the company so far, it also means that Samsung has to compete withitselfalmost as much as with other manufacturers. Between the low-cost Samsung Galaxy A13 5G and the mid-range A53, it can be challenging to decide which phone deserves your money. Should you spend additional cash on one of the more powerful Android phones, or opt for a real budget device that might not deliver the performance you need?

That’s where the Samsung Galaxy A23 5G comes in — a very competitive budget device up against some strong competitors. At $300, the Galaxy A23 is affordable without making many compromises to hit that number. In fact, with solid performance and an excellent 120Hz display, it may go down as one of the best budget devices this year. But, unfortunately, with competition so stiff, that still might not be enough reason to buy it.

With four years of security updates, a Snapdragon 695, and far and away the best display at this price point, the Samsung Galaxy A23 5G is one of the best values in the budget category you"re likely to see for quite a while.

Samsung has found a fairly consistent look for most of its A-series phones right now, to the point where it"s almost impossible to distinguish the Samsung Galaxy A23 from the more expensive Samsung Galaxy A53 5G that came out earlier this year. While the differences in design are few and far between, the most noticeable one is the inclusion of a headphone jack along the bottom of the Samsung Galaxy A23. Also, the power and volume buttons are slightly higher up along the right side, the selfie camera is in a teardrop notch instead of a hole-punch cutout, and the fingerprint sensor-equipped power button is flush with the plastic side rail.

While these minor cosmetic details differentiate it from the Galaxy A53, they"re unchanged from last year"s A22 5G. Thankfully, the same can"t be said for the display. While it sports that same teardrop notch for the selfie camera, the screen has been upgraded from a 90Hz TFT LCD panel to a 120Hz PLS LCD unit. Also, Samsung has switched from a MediaTek processor to Qualcomm"s Snapdragon 695 5G. As with previous generations, the A23 includes just 4GB of RAM and 64GB of storage, so you"ll depend on the microSD card slot if you need more storage.

The switch to a rectangular camera bump from last year"s square design is the most conspicuous update you"ll find here, matching up with many of Samsung"s current offerings. This camera bump shuffling has netted the Galaxy A23 an extra lens over the A22: a 2MP macro camera.

Unfortunately, the Galaxy A23 phone is missing an amplified earpiece. While the headphone jack is a nicety when I"m relaxing alone watching YouTube, I don"t always want to pull out my earbuds, and cramping my hand from cupping the bottom of my phone is no way to watch an hour-long video about speed running. There"s no shortage of budget phones that skimp on this feature, so as much as I don"t like it, it"s nothing outside the norm.

Speaking of modern-day sacrifices, you won"t find a charging brick in the box. While Samsung at least includes a cable with the Galaxy A23 5G (similar to the company"s more premium offerings like the flagship S22 Ultra), Samsung seems to be in lockstep with Apple on this charger issue. Flagship phone shoppers can usually find a high-end aftermarket charger worth buying; however, budget phones are more likely to be someone"s first smartphone, making a bundled wall wart all the more essential.

The A23 5G ships with Android 12, which includes all of the Material You goodness we"ve grown used to over the last year. It"s found on Samsung devices under the Color Palette menu, where you"ll also find Samsung"s theme store. You still have the option to customize your phone around your background colors, but the theme store has a huge selection of free and paid premade themes with custom app icons. While I didn"t buy any of the licensed Hello Kitty themes, the temptation was definitely there, especially after seeing how Material You has incorporated the background colors into the quick settings menu.

Samsung"s support guarantees are another compelling reason behind buying one of its A-series phones. The company has been very clear that it intends to give long-term updates for all of its devices, even budget offerings like the A23. With four years of security updates and three Android version updates, the Galaxy A23 is here for the long haul. It"s far too early to speculate what Android 15 will be like, but because the A23 ships with a build of Android 12, it"ll eventually get it down the line.

The move from the MediaTek Dimensity 700 to a Snapdragon 695 this year brings a noticeable performance bump. While plenty of this year"s budget phones, like the REVVL 6 Pro 5G, are still using the Dimensity 700 chipset announced at the tail end of 2020, having the more powerful Snapdragon 695 for little to no extra cost helps the A23 5G stand out as a much more appealing value for the money.

With its 5,000mAh battery capacity, the Galaxy A23 easily pushes into the multi-day range. It may not support wireless charging — as expected in this price bracket — but it"ll last longer than many more powerful flagships. If you forget to plug it in and need a top-off before heading out, don"t expect a lightning-fast charge. Samsung claims a max charge rate of 25W for the A23, but the highest charge speed I managed to measure was about 20W. Most of the time, it hovered around just 16W. If you prefer overnight charging — or even every other night if you want to use as many of those 5000mAh between charges as possible — these speeds are more than sufficient to get the job done.

Although the A23 only supports Sub-6GHz 5G, if you"re downloading anything over data, the 5G speeds are still pretty handy. 5G is nearly everywhere now, so if you"re upgrading from a 4G LTE device or slower, you"re likely to get at least a slight speed boost. The unit I tested was on AT&T, for what it"s worth, but I"m in a major metro area, so good coverage is pretty much guaranteed for me. The A23 5G can be purchased through T-Mobile, AT&T, and Samsung with or without a trade-in or unlocked from the usual retailers like Amazon and Best Buy. The US version of the A23 5G is compatible with GSM and CDMA networks, so if your carrier is AT&T, T-Mobile, Verizon, or the numerous "B.Y.O. Phone" providers piggybacking on those networks, the A23 should do just fine.

Samsung also has a variety of international versions available in the UK, Australia, Europe, select countries across Asia, the Pacific, and the Middle East. While the US version is limited to the black body and 4GB RAM+64GB storage formation in this review, depending on where you live, you may be able to get it in other colors like white, blue, and peach. The RAM and storage options can also vary from country to country, with 6GB and 8GB RAM options and up to 128GB of storage in some markets.

As I mentioned earlier, the Galaxy A23 5G uses a PLS panel, a bit of a step up from the TFT panel in its predecessor. It trades the lower power draw of that display technology for higher overall brightness, better viewing angles, and more detail. The Samsung Galaxy A23 5G practically has 180-degree viewing angles, and even though the resolution is only 1080x2408, I thought it looked pretty sharp. The screen can get bright enough to see in the harsh sunlight of the afternoon or under studio lights, but not to retina-searing levels. At max brightness, it"s easy enough to see where the display meets the bezel, as black levels look more like a dark gray.

Thankfully, with the brightness turned all the way down, it"s much harder to find the edge of the screen. The A23 does a great job of going very dim without black crushing or sucking the saturation out of colors. Overall, the dynamic range seems better than most phones in this price range. It"s still an LCD panel at the end of the day, so don"t expect OLED performance here. However, it"s more than good enough for casual YouTube watching, and the 20:9 aspect ratio will have you pillar boxed in enough to avoid the selfie notch close to 100% of the time.

Another strength the Galaxy A23 5G has over last year"s phone is a higher refresh rate. While the Snapdragon 695 may not be able to keep the frame rate locked at 120fps during your most demanding gameplay sessions, your doom-scrolling habits will appear very smooth. If you"re not a fan of high refresh rates or just want even longer battery life, it"s super easy to cap the refresh rate to 60Hz in the display settings.

The rear of the Galaxy A23 5G sports a quad-camera bump, along with a flash, but realistically you"ll only ever use two of them. The main camera clocks in at 50MP binned down to 12.5MP, while the wide-angle is just 5MP. Samsung isn"t bucking any trends with the other lens choices, either. Like many other recent budget phones, the A23 has 2MP macro and depth cameras tossed in for good measure. The 8MP selfie camera is the second-highest resolution lens on the phone, even after the main camera is binned down.

Without a full-res shooting mode, it feels a little disingenuous to market the main camera as 50MP since you"ll only ever get a 12.5MP shot from it, but that doesn"t make it a bad camera. It takes fine pictures, though there can be a noticeable delay between hitting the shutter button and actually snapping the shot. With an f/1.8 aperture, it manages to get by in well-lit photos, but it"s far from a low-light champ.

The selfie camera is the primary or secondary camera for most people, so it makes sense that it"s the one with the second-highest megapixel count on the Galaxy A23. Shots are unremarkable but usable in well-lit areas, and they suffer the same graininess the other cameras succumb to in any lighting that"s less than ideal. On the other hand, it doesn"t seem to have much artificial sharpness or any AI smoothing going on, so that"s refreshing.

The ultra-wide lens is just f/2.0, so the low-light performance is noticeably worse than the main camera. However, at 5MP, it"s still more than good enough to take shots for Instagram and plenty wide enough for landscapes and group shots. Unlike the main camera, there"s no night mode to try and save those dark shots, so once the sun is down, you"re stuck with either the flash or the main shooter.

With an impressive specs sheet for the price, the Samsung Galaxy A23 sounds more like a midrange device than a $300 budget phone. While virtually every budget device has some trade-offs to hit its low price, if you"re willing to make a few compromises, the A23 looks like one of the best budget phones on the market, purely on specs alone. While Samsung has pledged to support it for longer than other budget device manufacturers have, the biggest competitor to the A23 might just be Samsung.

Samsung"s strategy of offering a phone at almost every price point has worked out to great success. While this can lead to some of its phones feeling like they"re competing for the same customers, that can also make it easy to upsell someone to a better device. The Galaxy A53 from earlier this year is very competent and includes a better-looking OLED display with the same 120Hz refresh rate, and it has gone on sale for just $350 more than a few times since launching. The A23 is a totally usable budget device, and carrier deals are sure to drive its price even lower than it already is, but anyone who can spend just a little more would be much better off with the A53, provided it"s on sale at the time.

While the Galaxy A53 5G wasn"t a huge upgrade from last year"s A52 5G, it"s still above the A23 5G in Samsung"s lineup for good reason. If you opt for this step up, you end up with a notably better display, camera array, chipset, internal storage capacity, and even pick up an IP rating in the process. The only tradeoffs to speak of are the almost imperceptible shrink from 6.6-inch to 6.5-inch on the screen size, and losing the headphone jack.

With the same 5,000mAh battery capacity, and lack of wireless charging in favor of 25W wired charging, both devices will fit into your daily routine pretty much identically. While the A53 5G does cost a staggering 50% more than the A23 5G to bring you all those feature upgrades, it"s been discounted almost all the way down to the retail price of the A23 5G several times since releasing earlier this year, making it hard to ignore if you"re patient enough to get it on sale.

While the Galaxy A23 5G has a better-looking and faster display than the Moto G 5G, it isn"t an outright better device. With more built-in storage, more RAM, a higher resolution selfie camera, and an IP52 rating, Motorola still manages to trade blows with Samsung. The Moto G 5G has a higher retail price, along with the same chipset that Samsung is upgrading from this year, but with the same 5,000 mAh battery capacity, Sub-6GHz 5G, headphone and MicroSD card support, the extra cost may be hard to justify.

The company built a corps of designers with a capacity for strategic thinking and the tenacity that enabled them to overcome resistance by deploying the same tools—empathy, visualization, and market experimentation—that they use in pursuing innovation.

By any measure, his goal was achieved. Samsung now has more than 1,600 designers. Its innovation process begins with research conducted by multidisciplinary teams of designers, engineers, marketers, ethnographers, musicians, and writers who search for users’ unmet needs and identify cultural, technological, and economic trends. The company has built an impressive record on design, garnering more awards than any other company in recent years. The bold designs of its televisions often defy conventional style. With its Galaxy Note series, Samsung introduced a new category of smartphone—the phablet—which has been widely copied by competitors. Design is now so much a part of its corporate DNA that top leaders rely on designers to help visualize the future of the entire company.

It has been a bumpy journey. Despite strong support from top management, the company’s designers continue to face constant challenges stemming from its efficiency-focused management practices, which are deep-rooted. Shifting to an innovation-focused culture without losing an engineering edge is not a simple matter. It involves managing a number of very real tensions. Engineers and designers sometimes don’t see eye-to-eye. Suppliers must be brought on board. Managers invested in the status quo must be persuaded to buy in to idealized visions of the future. A risk-averse culture must learn to accommodate experimentation and occasional failure.

Samsung’s success in making this shift can be traced back to a single early decision—to build design competency in-house rather than import it. As we’ll describe, Samsung chose to create a committed, resourceful corps of designers who figured out that they could manage the tensions and overcome internal resistance by deploying the same tools that they use in pursuing innovation—empathy, visualization, and experimentation in the marketplace. The corps has helped institute policies and structures that embed design thinking in all corporate functions and provide a framework for reevaluating products in the face of dramatic technological change.

One of the world’s biggest technology companies and the leading subsidiary of Samsung Group, Samsung Electronics has been much in the news ever since it branched into consumer electronics and decided to go head-to-head with Apple (whose patent-infringement lawsuits against the company are ongoing). Competition from Apple and others has been intense; in the third quarter of 2014 the company’s profits dropped 60% from the same quarter of the previous year. By the first quarter of 2015 profits were recovering but were still below prior-year levels. Nevertheless, the big picture is one of impressive innovation and marketplace success. Samsung’s mobile division is the sole survivor of the radical market revolution led by the iPhone (the mobile divisions of former competitors such as Nokia, Motorola, and Ericsson no longer exist), and smartphone sales drove record earnings for the company in 2013. Moreover, Samsung has been the leader in the global TV market since 2006, generating a series of hit models such as Bordeaux, Touch of Color, One Design, and Curved Smart.

These design leaps all began with Lee’s 1996 resolve—triggered in part by a consultant’s report on Samsung’s innovation deficiencies—to instigate a design “revolution” in the company. (This wasn’t the first major leap for Samsung. In 1993 Lee had launched an initiative to integrate Western practices on strategy, HR, merit pay, and design into the conglomerate, but he had been unsatisfied with subsequent progress.) To fuel its design revolution, the company could have sought first-rate expertise from outside. That certainly would have been the fastest approach, and a number of senior managers pushed to have an internationally known Korean designer take over the design function. But other executives persuaded Lee to nurture internal designers who would focus on the company’s long-term interests rather than just their own projects.

Ethnographic research in 2003 revealed that TVs are off far more than they’re on in most homes, so Samsung improved the visual appeal of its TVs starting with this model. It was a huge hit.

Numerous Samsung executives now agree that dependence on outside expertise would have done long-term damage. Developing in-house expertise, while laborious, created a group of designers who take a holistic view. An Yong-Il, the vice president of design strategy, puts it this way: “When we had our own place in the organization, we started caring about the future of the company.” The designers also developed a capacity for strategic thinking and a tenacity that enabled them to overcome resistance over the long term. It seems doubtful that any group of outside designers, no matter how brilliant, would have been able to do that—even with support from the chairman.

Even in a company that embraces design principles, the reality is that designers must take steps to ensure that their ideas prevail as originally conceived. To do this they need to consistently empathize with decision makers from other functions throughout the process.

Consider, for example, the attempt by Lee Min-Hyouk, Samsung Mobile’s creative director, to “sell” what was eventually nicknamed the “Benz phone” after a Norwegian newspaper likened it to the Mercedes-Benz. It was the first flip-cover mobile phone to have no external antenna. Lee, then a junior designer, knew that in order to persuade the engineers to eliminate the antenna, he’d need a better reason than to make a phone look good. To bring them on board, he reached well beyond the usual design role and took on an engineer’s mindset, coming up with a new hinge design that created an internal space for a larger and more effective antenna. He also studied different types of paints that would enhance signal reception. “I had to imagine a new design for engineers as well as users,” he says. The engineers were won over, and the phone ultimately sold 10 million units.

Design must also win the support of suppliers. If parts makers are unwilling to collaborate, no new design, no matter how compelling it may be, can survive. For example, when Sa
