The Pocket mode is a handy feature that you will find in different smartphone models.
The pocket mode can prevent misoperation on the touch screen while the device is in your pocket. This mode uses a mobile proximity sensor to turn off the touch gestures and block the screen, fingerprint scanner, and power button.
How to Enable Pocket Mode
Open the Android settings. Then navigate to “Lock screen“.
Then switch to “Pocket Mode” by setting the slider to “On“.
This will lock touch control on the phone when the device is in a pocket. The proximity sensor will disable touch gestures and will block the screen along with the fingerprint scanner and power button.

Handling the device firmware (firmware upgrade required).
The proximity sensor is broken.
