Just updated to Android 4.0 Ice Cream Sandwich and everything was fine....then almost all my apps crashed then my screen froze. I figured it was a regular freeze up and clicked the power button. It didn't work so I pressed it down and it powered down as usual. Now...it isn't powering up properly it only goes to the screen start up thing (the swiggly lights) and doesn't go past it. Any tips on how to fix it?
