ok this has been going on for a while but getting worse. I'm not sure what's causing it. My phone will go to sleep and won't wake up again through touch or buttons. Only way to get it going again is through removing my case, taking the back panel off, removing and reinstalling the battery. This sucks since those little tabs on the body glove case I'm using don't like being removed continuously. When I boot the phone up I get a Sorry Process System is Not Responding. The phone also brings back a notification from a few days ago that I've cleared countless times now. Any way for me to find out what's causing this without removing every application I have installed? Why does this keep bringing back an old notification or is that my carrier?
