Almost all the gadgets that we use today are equipped with touchscreens. These screens need careful handling otherwise they can malfunction easily. Apart from accidental breakage, there are many other reasons that can make the touchscreen unresponsive. The touchscreen of your android phone can stop responding to either some areas or the whole of the touch screen stops working. Android touchscreen problems are common and here in this article we will troubleshoot and fix touchscreen by following these effective tips.
Fixing the Android Touch Screen
Restart Android Device
We will start with the simplest method which is restarting the phone. Turn off your phone and wait for 10 seconds to restart it again. This procedure is also called the power cycle. It will remove any minor software bugs or hitches. In most cases, this step will resolve the touchscreen issues.
Just as we restart windows PC in safe mode, you can easily start your android device in a safe mode to counter most of the errors. When a device boots in a safe mode, it disables all the third-party applications, and only operating system and system applications run. So if in safe mode, the touchscreen problem vanishes, it means some application was causing this problem. Now you can delete the external apps one by one until the touchscreen issue is fixed.
To restart an android phone in safe mode, press the power button on the phone and on-screen, again press and hold the power-off icon for a few seconds and it will display the option “Reboot to Safe Mode”.
“Note: The above method will work for android phones with Jellybean 4.1 and above versions.”
For phones with an older version of Android, you can follow the below steps.
- Press down the power button until it restarts.
- After the phone restarts, release the power button and press both volume (up and down) buttons together and it will open in safe mode.
Check Memory Usage
There is no denying the fact that touchscreen responsiveness depends a lot on the device’s memory. If the memory or RAM of an android device is almost full, it is bound to give you touchscreen issues. The memory is used while running heavy apps so you need to either remove or “force stop” them to free some memory.
Open settings>memory on Android phone. It will show you the average memory used besides some other stats. It will also display the total memory consumed by apps.
Click on “Memory used by apps”. It will show all the apps and the memory used by respective apps. Now select the app which you are not using anymore and from more settings(…), “force stop” it.
Those who do not want to free the memory space manually can install one of the memory cleaner apps from Google Play Store. There are many memory management apps available, both free and paid. Some of the best free apps are Clean Master and memory booster.
Turn On GPU rendering
Most of the applications are designed not to use GPU rendering which means that these apps do not use graphics processors or hardware to enhance their on-screen visibility. It also enhances the UI transition which in turn makes the touch more responsive.
To turn on GPU rendering, go to Settings>Developer options>Force GPU rendering and turn on the button.
There are multiple touch-points on a touchscreen. If the screen is behaving intermittently in different areas of the screen, then you should test the screen for faulty areas. The easy way to test the touch points is to install a touchpoint tester app. These apps check the screen areas by registering your finger’s touch on the screen.
Calibration of Android Touchscreen
If your android phone touch screen is behaving indifferently and the colors are also somewhat distorted, calibration is the best solution in that case. Visit Google Play Store and download Touchscreen calibration App. This is a free app that will make sure your touches are detected with improved accuracy and also improves touch responsiveness. The app calibrates different gestures like single tap, double-tap, swipe, zoom, and more.
Check battery Charger
In case the touch screen of your android phone does not work while the phone is in charging mode, it is time to check the charger. Make sure you are using the original charger that was bundled with your android phone. Sometimes we just see that the output pin is the same as that of the original pin and use that for charging without reading the voltage and ampere ratings. Even if the voltage is the same, the ampere ratings can differ thus causing touchscreen problems.
“Warning: Do not buy third-party cheap chargers just because they are compatible with your device. Always buy an original charger.”

Remove tampered glass
In some cases, it is found that cases or protective glasses for screens often cause touchscreen issues. Remove all the cases, third-party glasses, and lamination, and try the touchscreen. Hopefully, this might work for you.
If none of the above methods work for you. You can hard reset the phone. This process will erase all the user data and the phone will be reset to default settings like a new phone. Although most phone brands differ in the procedure to hard reset it, the most common method is to press the power button and power up button simultaneously. The phone will now restart in recovery mode and you need to navigate (by using volume keys) to “wipe data/factory reset” mode. Now select this option by pressing the power button.
“Note: In Samsung Android phones, you have to press power + volume up + home button to hard reset it.”
If somehow, you are able to use the touchscreen, you can reset the phone to factory defaults by navigating to Settings>backup & reset>Factory data reset. Use this option only in case you are sure that touchscreen issues are not related to hardware or physical breakdown.
“Important: Hard or Soft reset will wipe out all the user data so it is vital to back up all your data by connecting android phone to PC with a USB cable”.
