The screen doesn't turn off during a call when you hold the phone close to your face (Android 9.0)
- Why doesn't the screen turn off during a call when you hold the phone close to your face?
- Android 9.0 Pie
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 recognise it by its protruding tab.
- If your device has a screen protection film, make sure it's specifically intended for your Xperia model. It is important that such a protective film has 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.
- Make sure to remove the transparent film that covers the touchscreen when you first buy it. This film typically has a protruding tab.
- Check that any protective film that your device uses, has the holes for the proximity sensor and the front camera in the correct positions. The sensor is placed at the top of the device above the screen. To verify the exact location of the proximity sensor for your Xperia model, refer to the User guide. You can view an illustration of the device and the main hardware parts in the Getting started chapter under Overview. If you can't verify that the protection film is correctly fitted, remove it.

Updating the system software
The easiest way to install a software update is to do it wirelessly from your device. However, some updates are not available for wireless download. In such cases, you must then check for new software using a USB cable and a computer running Xperia Companion.
To download and install a system update wirelessly
- If you are using a device with multiple users, make sure you are logged in as the owner.
- Make sure your device is connected to the internet. It is recommended to use a Wi-Fi network instead of a mobile network to download new software so that you can avoid data traffic costs.
- Find and tap Settings > System > Advanced > Software update > SYSTEM.
- If a system update is available, tap UPDATE.
- When the update is installed, tap RESTART.
To update your device using a computer
