The touchscreen isn't working properly
There are a number of solutions that you can try if your touchscreen is over-sensitive, acts on its own, is unresponsive or has poor sensitivity.
- The touchscreen's performance may be affected by dirt, heat, or the use of device covers or screen protectors:
If you have applied a screen protector on your device, be sure that it is properly fitted and that there are no air bubbles, and that there is no dust or moisture under the screen protector.
Remove any protective case or cover from your device to verify it's not interfering with the touchscreen.
Wipe the screen with a clean and dry cloth to be sure that your touchscreen is clean. Be sure that your hands and fingers are clean and dry before using the touchscreen.
If the device gets too hot, the touch functionality may be affected. Let it cool down and then try using the touchscreen again.
- Turn off your device and then turn it back on. By doing this, you turn off all running applications and free up memory, which sometimes automatically solves the issue.
- You can force your device to restart or shut down in situations where it stops responding or won't restart normally. No settings or personal data get deleted during a forced restart.
To Force the Device to Restart or Shut Down
- Press and hold down the power key and the volume up key at the same time for 10 seconds.
- Your device vibrates once. Depending on whether you wish to force the device to restart or shut down, proceed as follows.
- If you wish to force restart the device: Release the keys at this point. The device restarts.
- If you wish to force shut down the device: Continue pressing the keys. After a few more seconds, the device vibrates three times and turns off.
To Turn On the Device
- Press and hold down the power key until the device vibrates.
- Wait a while for the device to start.
- If the problem occurs when your device is charging, be sure that you are using an original Sony charger and a USB cable specifically intended for charging your device. Other chargers may have a negative impact on the functionality of the touchscreen.
- If there is a memory card in your device, remove it and restart the device. If removing the memory card solves the issue, your SD card may be damaged. In this case, you need to get a replacement SD card for your Xperia™ device.
- Use safe mode to check if any downloaded applications are causing the problem. In safe mode, your device only starts with software and applications that were already installed when you purchased your device. If the device's performance improves in safe mode, it's likely that one or more of your post-purchase downloaded applications are affecting the device negatively. You can exit safe mode and restart the device to uninstall the application or applications that you suspect are causing the problem. If the problem is recent and you're not sure which application is causing the problem, you can start by uninstalling the most recently downloaded application.
