I was playing music and in I'm it crashed and rebooted. After that I thought no big deal but then it stopped working by producing a static screen. Like on tv when you change it to a channel you don't have. I thought for sure it was messed up. I turned it off and went through a re boot screen. My app center would always run in the background after I checked and it was no longer running. I also had 43mb free. Instead of 28 which I had before. Today I turned it on and checked to see if app center was running and it wasn't but yahoo im was and I didn't even use it. Anyone know what happened? I did see an increase in speed, the app memory being higher than before.
