Hey everyone, I need some help big time. My phone is unusable. When making a phone call, I cannot hang up and the phone becomes completely unresponsive. The only thing I can do is to pull the battery. Definitely related is that once the screen goes off after I've initially turned the phone on I cannot unlock the screen...it is completely unresponsive. Again, all I can do is pull the battery and restart my phone. It's basically a one-use phone. I have done a hard reset, clearing all data and restoring to factory defaults. What else can I do to fix this? I have not rooted nor done anything funky to my phone. I did nothing different than general use to cause this problem.
