I have had this problem one or two other times, and it progressively got worse. First it froze with nothing on the screen, but the back-light was still on. I removed the battery and replaced it, and it worked fine. A few months later, it did this same thing, but the battery trick wasn't working, so i tried cleaning off the terminals, which did the trick but i still ended up doing a factory reset. This time, it doesn't seem to respond to anything. I cleaned the terminals, let it sit overnight just incase some weird demon got into it =P, and it still wont respond to either charging or the power button. My brother has the same phone, and I tried his battery and it didn't make a difference. I have never dropped the phone, got it wet, severely thrown it across a football feild, etc. It has been in an Otterbox case that has not even seen the likes of a floor. What else can I do? If i do take it back to Verizon will i be eligible for a replacement? (I do think this is some sort of manufacturor's defect, unless i contracted some strange virus from an app or something of that nature) Any help is appreciated!
