This morning I woke up to find my iPhone dark. If I pressed the home button to turn on the screen, the backlight would flash on briefly and then die. I've turned it on and off, done a hard reboot (home+lock), and I'm in the process of trying a restore.
Has anyone ever seen a similar issue?
The phone was purchased last June with a contract from ATT from an Apple store. If I take the phone in, will they fix it or replace it?
What should I do next?
You should take your phone in. They will fix it if they can and it's cheaper for them than giving you a new.
If you try to fix it yourself they can put the blame on you, so don't touch the hardware.
It may be your proximity sensor. It's what causes the backlight to turn off when you put the phone to your face and turn back on when you move away. I was told that that's one of the few things Apple Care does actually cover.
But before you take it in, do you have a bumper on your iPhone? If so, it may be covering the sensor, which, while facing the phone, is just to the left of the earpiece. If your bumper (or maybe a dirty screen protector) is covering it, that may cause the screen to stay dark.
Hope this helps!
