Your smartphone comes with a default touch sensitivity which is set at an optimum level of use. This level is the perfect touch sensitivity for most users. However, you may sometimes need to change the touch screen sensitivity of your device. One of the situations, when yot may need to do so, is when you get a touch screen protector for your phone. The covering may delay the touch reaction on your screen. In this case, it is advised to increase the touch screen sensitivity on your phone for a smooth experience. Today, we will show you how you can change touch screen sensitivity on Android and iPhone.

Step 4:Drag the slider that appears on the screen towards the right to increase Touch Screen Sensitivity. Drag it to the left if you wish to reduce the Touch Screen Sensitivity.

While Android offers you to set a custom touch screen sensitivity level suitable to your liking, iPhone only provides you with two options. Some hit-and-trial may be required to set the perfect level of sensitivity. If you’re still experiencing some lag on your phone, you may want to get it checked by a professional.

iPhone is famous for the quality of its screen, which is designed to be very sensitive to finger touches. After all, who would want to use a phone whose screen only reacts when the screen is pressed really hard? But some users complain that the iPhone screen sensitivity is too high that a mistouch or even a dot of dust can trigger something on the screen. No matter what are the reasons for this issue, the sensitive screen hinders our usage.

Screen protector - You can try to remove the iPhone screen protector to see if the screen sensitivity issue still exists. Sometimes, an inferior protector will even damage your screen.

Clean screen - It is important to keep the iPhone screen dry and clean. A wet screen will become extremely sensitive. If you want to clean the screen, please use alcohol-free fluid and a lint-free cloth.

iPhone is charging - If you find that your iPhone screen becomes sensitive only when it is charging, you can try to unplug it to get rid of the issue.

There are some obstructions that can be ignored easily but still impede the screen from reacting to finger touches normally, for example, small dust, a screen protector. To eliminate these causes, you should:

1) Clean the screen with a cloth. To clean the screen to the finest condition, wipe the screen cloth soaked with ethyl alcohol (not wine, spirit or beer!) and then dry cloth.

2) Remove the screen protector and see whether the screen functions normally without it. If you have to use a screen protector to ensure the safety of the screen, use a well-established brand that will not block normal screen usage.

In some cases, restarting your iPhone can help you fix iPhone screen too sensitive. To turn off your iPhone, you can long press the Power button as well as Volume Up/Down button. Then, you will see the slide to power off prompt on your screen. Drag the slider to the right place, and your iPhone will be shut down. Next, power on your iPhone again by pressing the Side button until the Apple logo is seen.

Easy as it seems, a hard restart can also solve a large number of problems, like iPhone touch sensitivity issues. It is different from the normal reboot in that it is more complete.

Press and release the Volume Up button and then do the same to the Volume Down button, and finally hold the Home button till the Apple logo appears on the screen.

Up until now, iPhone 3D Touch is installed on models from iPhone 6s to iPhone XS Max. 3D Touch can sense how deeply the user presses the screen, intending to provide a multi-functional touching experience. However, over sensitivity of iPhone 3D Touch will cause screen touch hard to use.

To turn down the sensitivity of 3D Touch, you should first find the 3D Touch menu as shown in the image below, then use the slider under the menu to adjust the sensitivity.

Another effective way to deal with iPhone touch screen sensitivity problem is turning on Touch Accommodations. Here are the detailed steps for you to set Touch Accommodation.

In the past decade, LCD monitors have replaced CRT screens for all but the most specialist applications. Although liquid crystal displays boast perfect

If the screen flickers, make sure the display settings in Windows match the native resolution and refresh rate for the display. Find the native resolution of a flat panel display on the box, in the specifications, or in the printed material that came with the display. Some common native resolutions are 800 x 600, 1024 x 768, 1920 x 1200, and 1680 x 1050. The most common refresh rate for LCD displays is 60 Hz. This normally cannot be changed for flat panel displays using Plug and Play settings. However, if you are using special video software to increase or decrease the refresh rate, change the refresh rate to match the default refresh rate specification of the display.

If your screen flickers in Windows 10, it is usually caused by incompatible apps or display drivers. To find out whether an app or driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you"ll need to either uninstall the app or update the display driver.

Otherwise, you can get the latest updated video drivers from the video hardware manufacturer"s website. The following list shows some of the video hardware websites:

If you cannot select the native resolution after updating the video drivers, the graphics adapter in the computer might not support that resolution and might need to be upgraded.

Check the video cable connections. Unplug the cable and inspect the cable for damage. If the cable is damaged, replace it with a new cable. Try to use cables less than 3 meters (10 feet).

Check the environment around the display. Displays are sensitive to magnetic fields. Speakers, florescent lights, fans, cell phones, radios, and any other electrical device can cause flickering. Temporarily move electrical items away from the display to see if they is producing a field that causes the flicker.

To see if the video coming from the computer is causing the problem, temporarily connect the display to another computer, such as a notebook computer.

If the flicker is gone when the display is connected to another computer, the graphics adapter hardware on the first computer might need to be upgraded to use the display.

OptoFidelity GoldenEye is an automated display test system that is scalable and capable of producing reliable and consistent display quality data. It is capable of testing MURA / MURA detection, uniformity but as well particles within display stack and display surface dust detection. The OptoFidelity™ GoldenEyE software is used with different camera and hardware setups and integrated to RD and factory testing environments. You can read more details about the solution from OptoFidelity™ GoldenEye solution page.

In the society of 2018, display devices are everywhere: phones, tablets, TVs, smartwatches, cars, ATMs, elevators, etc. According to sources*, the annual volume of small and medium (≤ 9”) displays is steady at 3 billion pieces, and the quality output of production lines in module and device factories requires high-precision and consistent display inspection solutions. Currently, most of the production lines utilize the operator inspection model, where individual operator performances have variations and inspection accuracy cannot be guaranteed. In addition, as production lines are being automated to improve throughput and quality control, display optical quality inspection can no longer be left to human operators.

When considering the details of display inspection, there are challenges involved in controlling the ambient lighting environment, viewing distance, impact of pixel size variations between products, dust and particles on top of the display surface, and excessive operator handling that itself is a risk for panel breakage. Display inspection also involves lighting on the display and checking optical qualities such as luminance uniformity and color performance. Other Interesting functional defects include missing lines, light leakage, particles within the display stack and flickering. These light-on inspection steps often require a specific test setup, and the inspections are usually very time-consuming.

The OptoFidelity ™ GoldenEye display test solution is used in a lab environment for RD purposes, and mass production lines for high-volume production quality assurance. In a lab environment, the GoldenEye display inspection tool can be used to check the display quality of small sample batches and receive timely data of display quality. The setup is simple:

Typically we include hands-on training for customers to help them start using the SW and introduce the DUTs to the system. In a lab environment it will also be easy to fine-tune the setup and adjust it appropriately with changing needs.

In a production environment, the GoldenEye display testing solution is packaged into an automated or semiautomated, stand-alone tester or inline system according to customer requirement. The HW setup will be carefully designed to meet customer requirements and allow high-quality performance of the tool. Fine-tuning will be performed by OptoFidelity, and on-site support with hands-on instructions is an integral part of customer service. OptoFidelity is committed to working closely with customers to bring the testers to the factory floor or clean room environment.

As an example, the OptoFidelity team has helped a customer in the process of fine-tuning inspection criteria and defect analysis parameters based on operator judgement results. By aligning the tester output with the traditional operator output, the GoldenEye display test solution can avoid excessive false positive results. The fine-tuning of defect analysis parameters can also be done by the customer, as tuning can be performed simply with existing data without the need for re-measurement. Another example is the usage of the GoldenEye display inspection tool sensitivity map feature. When a customer display product had darker edges as an inherent optical defect, the sensitivity map was used to ignore these areas. It was easy to implement as well as an effective solution to treat every display panel equally. The beautiful thing was that the sensitivity map did not just mask away those areas; it actually has a thresholding feature: Only the defects exceeding a pre-defined threshold will be reported.
