Black screen in call

When receiving a call the screen goes black, when the call ends it turns on again. Any solution or wait for the update to android 10.

  • I already solved it was the protective foil.

  • When receiving a call the screen goes black, when the call ends it turns on again. It just started happening.

    There is no the protective foil to remove.

    A combination of dirt and the cover has probaly closed the screen. 
    It's part of the battery saving feature. This is a very sensible 
    function.
    

    As soon as I cleaned the area, the phone worked normally again.
