Solved My Screen Goes Black During A Call And Does Not Turn On Again Samsung Galaxy Siii Mini
Chosen Solution If i call someone the screen goes black and does not turn on again Sounds like a problem with the proximity sensor. I have seen this happen when we worked on a device and had the proximity sensor seated incorrectly. Probably not what happened here unless you have repaired the phone or it has been dropped possibly. Restarting the phone should fix the problem temporarily until you make a call again....
