Yesterday in my notifications panel I had an "update" icon. So I flipped it down to check it out and there was no application attached to it. It just said "update" and it had already been installed. Since then, my phone has shut off, wouldnt charge, and required a battery pull. Now it wont let me access certain apps, when I make a phone call it lags about 20 seconds then puts the call through. What is going on? I have "lookout" the mobile security suite. Any ideas??
