Touch Screen Not Working: How to Fix?

If your touch screen doesn't experience any physical damage but suddenly stops respond to your touch, this may be caused by software issues.

Before rushing into any other troubleshooting procedure, restart your Android phone or tablet to fix software glitches that may prevent the screen from functioning. To restart an Android device with the touch screen is not working properly:

• Press and hold the power button until the screen becomes black;

• After 1 minute or so, hold the power button again to power on the device.

In many cases, the touch screen will respond normally after the device reboots.

2. Remove Memory Card & SIM Card

Sometimes, a faulty memory card or SIM card should take the blame. Therefore,

• Power off your device (keep holding power button if the screen is totally unresponsive);

• Remove back cover of your Android device and take off memory & SIM card;

• Reboot the device and see if the problem is gone.

3. Put Device in Safe Mode

Corrupted or troublesome third-party apps could also cause touch screen problem on Android phone or tablet. Under the safe mode, all third-party apps that you download will be disabled. So if the touch screen works well in safe mode, then you should uninstall some of the third-party apps, especially those that were installed recently before the touch screen problem starts.

• Power off your Android device;

• Long press power button to reboot the device;

• When you see the Samsung, Nexus, LG or other brand logos, release the power button and hold down the Volume Down button;

• Release Volume Down button when the device boots up with a Safe mode indicator on the bottom left corner.

If your touch screen just lags or respond incorrectly, you can also try to enter safe mode in this method:

• Hold the power button until the power options menu appears;

• Long-press the Power Off ;

• When you see the message whether to reboot your device into safe mode, tap 'OK'.

4. Factory Reset Android Device in Recovery Mode

If the touch screen is completely unresponsive, factory resetting the device in Recovery Mode may help.

The steps to enter recovery mode are different for different Android models. Here are the ways to boot into Recovery Mode for some popular models: Samsung Galaxy, HTC One, Nexus, LG G, Moto Droid.
