- Android™ 9 or higher
Your device has a sensor that detects proximity. The proximity sensor turns off the touch screen during voice calls when your ear is close to the screen. This prevents you from unintentionally activating other functions on your device when you are engaged in a call. The proximity sensor is located on the upper front part of the phone (above the display). The time needed for the sensor to turn on or off the display before or after a call is fixed. It can take up to a few seconds for the display to turn on or off.
The proximity sensor may not work as intended in the following cases:
- You may have forgotten to remove the temporary transparent protection film that covers the touchscreen when you first buy it. This film is only designed to protect the screen during shipping and is easy to peel off. Often you recognize it by its protruding tab.
- If your device has a screen protection film, make sure it's specifically intended for your Xperia® model. Such a protective film must have the holes for the proximity sensor and the front camera in the correct positions.
- Make sure the proximity sensor is clean; many problems with the proximity sensor may be solved by cleaning it.
- If you use a case or cover which is not well suited to the phone, it may impact the functionality of the proximity sensor. The case may cover the sensor.
- There may be other causes for the sensor not working as intended.
Try these methods one after the other. Verify after each method whether the problem was solved before trying the next one.
