I got a ghost armor screen protector for my Verizon TP2. I used the spray to get the cover on and water must have gotten into the phone. The phone sticker is now showing water damage and occasionally my phone pops up the shut down notification acting like the end key is being held. I do not know yet how badly this will effect calls yet. Any suggestions? Anything to do about the sticker?
