Not sure if anyone else has had this problem with there's. If i'm on the phone with someone I cant access my screen (it just stays black, but I can still talk fine and once im off the line with whoever everything goes back to normal.) An example is I was calling the doctors office today and it says press 1 to do this and press 2 to do that. But since my screen wouldnt come on when I took my phone away from my ear or when i pressed the power on button I couldn't do anything. I couldn't even end the call because I couldnt access my screen. However sometimes it will come on for a second or two but just randomly. I hope I explained this right where everyone can understand and hope someone has a solution. Thanks
