Display going black intermittently and proximity sensor not working
I just had the screen replaced on my wife's iPhone 6. Prior to the replacement everything was working fine and now after the replacement the screen goes black every so often (typically between 1-5 mins). The phone is still functioning and the back light is still coming through. I then need to lock and unlock the phone which the screen comes back on for a while. I have also noticed that the proximity sensor no longer works since the replacement as well.
Any help or suggestions would be greatly appreciated.
