Hi, the screen on this iPhone 5 will go black like it’s locked if I lock it but I cannot activate the screen again no matter what I do after it’s locked. Eventually I’ll get it to work but it takes a while. The only way for me to use my phone is to keep it on and unlocked the entire time. It’s only been opened one time at the Apple store. I’m thinking maybe the proximity sensor, but I’m not to sure about that one. Please let me know what you come up with! Thanks!
I would try a new screen has this problem before and noting would activate it but then worked for a while. I new screen fixed mine
