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:
o
If you have applied a screen protector on your device, make sure that it is properly fitted
and that there are no air bubbles, dust or moisture under the screen protector.
o
Remove any protective case or cover from your device to verify it's not interfering with
the touchscreen.
o
Wipe the screen with a clean and dry cloth to make sure that your touchscreen is clean.
Make sure that your hands and fingers are clean and dry before using the touchscreen.
o
If the device gets too hot, the touch functionality may be affected. Let it cool off and then
try using the touchscreen again.
o
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.
o
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.
o
If you are not wearing gloves, make sure Glove mode is turned off.
o
If the problem occurs when your device is charging, make 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.
