I have a sprint hero that I rooted and have been messing around with for a while now. I noticed that the other day I was cruising the web, when all of a sudden the app shutdown on me. I thought that was strange, I looked at the battery and it was full charge. I tried to access it again and the same thing. The notification bar that you slide down won't stay down. I eventually shut it off and left it alone. Today I pick it up to play around with it some more and I opened up an app and sure enough after 10 minutes of use it did the same thing. None of the apps will stay open. I am not sure but I was wondering if anyone had some feedback for me.
