There is a light sensor near the receiver on the screen of the mobile phone. When making a phone call, when the phone is close to the ear or blocked by other objects, it will automatically turn off the screen to prevent misoperation. When there is no occlusion, the screen will automatically light up.

If the phone leaves the ear, the screen is still not bright:

The phone will also sleep automatically. At this time, the light sensor does not work, and the screen will not light up automatically. You need to press the power button to light up the screen.

If you turn on handsfree, plug in headphones or return to the main interface or other applications during a call, the optical sensor will not work.

You can try to open the holster to make a phone call, or restart the phone.

If all can't be solved, it is recommended to back up mobile phone data (phone book, SMS, pictures, etc. ), restore the factory settings or take the purchase invoice to the after-sales service point for maintenance.
