Today’s mainstream phones are mostly using touch screens or touchscreens. Including phones with the Android operating system that currently dominates the global mobile market.
Android phones are not free from a variety of problems, including one that is an error touchscreen and cannot respond to touch. This is fairly reasonable because you can touch the phone screen up to hundreds of times a day and problems can arise at any time.
Before you panic and decide to bring your Android phone to the service center, do these seven ways to overcome the error touchscreen that is summarized from wikiahow:
1. Restart the Cellphone
This method is fairly simple, but this method is quite effective. Restarting your cellphone can turn off all cellphone functions and refresh the background service, which may crash and cause touchscreen problems.
The trick is to press and hold the Power button, then select the Restart option if your screen is still functioning partially. If not, press and hold the Power button for a few seconds to turn off the phone.
2. Enter Safe Mode
Safe Mode on Android allows you to use a cellphone with blank software, without the services or applications you have installed before. If your touchscreen can function normally in safe mode, chances are that your problem is caused by a third-party application.
To enter Safe Mode, press and hold the Power button. After that press and hold the Power Off menu and you will see a prompt to enter Safe Mode.
Click Accept or tap the screen twice and your cellphone will enter Safe Mode. To exit Safe Mode, repeat the procedure but select the Restart option.
3. Display diagnostics
Currently, there are many applications on the Google Play Store that can diagnose your cellphone display. One recommended application is Display Tester which can be downloaded for free.
After installing the Display Tester, enter the Tests tab. Here you can perform various types of tests such as detecting dead pixels, burn-in OLED screens, multi-touch statuses and much more.
If you get a positive result on a multi-touch test, that means the touchscreen is functioning normally and third-party applications might be the cause. Try to see the application that you just installed or if you need to consider doing a factory reset.
4. Remove the Screen Protector
To protect the touchscreen from scratches and collisions when falling, many people now have screen protectors or screen protectors on their Android phones. But, this plastic or glass panel can block your touch signal from reaching the display panel.
If your touchscreen has a partial error or is not responding, try removing the screen protector. This may not be able to fix the problem completely, but it can improve the response on the screen with the problem.
5. Increase Screen Latency
If the touchscreen on the cellphone has a partial error, you can increase the screen latency using third-party applications such as Touchscreen Repair. This application works by calibrating the screen to reduce response time.
This application will ask you to touch a portion of the screen. Based on your phone’s internal, this application then artificially reduces screen latency.
6. Remove the SIM Card
This method can overcome the problematic touch screen. The method is to turn off the cellphone and unplug it from the charger. Take out the SIM Card and memory card on the cellphone.
Turn the phone back on and check if the touch screen has returned to normal. If the touch screen is functioning normally, reinsert the items that you removed one by one until you have identified the cause.
7. Dry the cellphone
Android phones that fall or sink in water can cause internal damage, including a sudden touchscreen that doesn’t work. Try to dry your cellphone thoroughly to overcome it.
The method is to turn off the cellphone, dry the cellphone with a towel and place it in a drying material such as silica gel. Leave the phone for about 48 hours.
