So here is my problem. My phone was just replaced a couple of weeks ago because of a headphone issue. This isn't relevant other than I have a new..ish phone. Starting a couple of days ago, my phone started acting like it was being touched. It was sending random texts to people and when I'd open up anything with a keyboard, it would frantically start typing and screwing up. If I'm using the Facebook app, it randomly brings up profiles and likes status updates and just acts nuts. I've restarted it and hard reset it several times and nothing is fixing the problem. I can't even make a phone call without it trying to call everyone in my contact list and dialing random numbers. Now, it won't even unlock. Sometimes, if I used another finger it would unlock but it's totally unresponsive right now. Any ideas?
