Default Display off during outgoing call


Only during outgoing calls the display turns off and won't turn on not even by pressing the power button. On incoming calls the proximity sensors on the right of the ear piece work ok. They turn the display on and off when needed.
Is the outgoing call using different sensors? I did replace the screen myself, so this might be a related issue, but since it works ok on incoming calls, i wonder...

My guess is it's either a sw issue or it uses different sensors for incoming and outgoing calls.
So did any of you had this issue and have a solution?


L.E.: I managed to reproduce the issue on incoming calls, so at least that narrows it. I'll take down the screen and re-position it.
