I just got my phone a little over two days ago and it was working just fine. I woke up from a nap and all of a sudden the screen goes blank when I slide it up. Upon further investigation I realized that the screen isn't completely black but the backlight is just really really low. I tried messing with the backlight settings and did a couple battery pulls and still nothing. Any ideas?
Surly not normal, definitely take it back for a replacement.
Depending on the unlock service you used, they may issue you a new code if you explain the situation.
