I noticed that the proximity sensor does not work well with high lighting levels or with direct sunlight on the screen.
In practice, when you make a call does not switch off the screen approaching the phone to your ear.
In brightly lit environments it works regularly.
Is this hardware or software error?
How do I fix this problem?
