What should I do if my touch screen is unresponsive?
If your touch screen isn’t responding, the first thing to try is a simple restart. Press and hold the power button until the power menu appears, then select “Restart” or “Reboot.” This action can clear temporary glitches that might be affecting its responsiveness. If the device does not respond to the touch at all, you may need to force a restart by holding down the power button and volume down button simultaneously for about 10 seconds.
If restarting does not resolve the issue, you can try booting your device in safe mode. Safe mode disables third-party applications that might be causing the problem. To enter safe mode, press and hold the power button until the power options appear, then tap and hold “Power Off” until you see the “Reboot to Safe Mode” option. Tap “OK” to restart in safe mode. Once in safe mode, check if the touch screen works properly. If it does, a third-party app is likely the culprit, and you may need to uninstall recently downloaded apps.
Why is my Android touch screen not working after a software update?
Software updates can introduce bugs that may temporarily disrupt the functionality of your touch screen. Sometimes, new features or system changes conflict with existing applications or settings, leading to unresponsiveness. To resolve this, one of the first steps is to restart your device, which can help clear any issues caused during the update process.
If the problem persists after rebooting, consider performing a factory reset as a last resort. Before doing so, ensure you back up your data to avoid losing any important information. Go to Settings > System > Reset options > Erase all data (factory reset).
