My Samsung Galaxy Prevail is a little over a week old, and after 3-4 days of having it I had rooted it, and put Shabbymod 0.9-Loaded on it, than I did a Factory Restore, as recommended. But during the little time it was unrooted, it frooze too, but infrequently. Now it has gotten to the point where whenever I want to use it again I have to pull the battery. What happens is I press the power button, the screen flashes on, but the touch screen doesn't work. My Live Wallpaper still moves, etc. But I can't touch anything. Also I have woken up to my phone shut off when I had kept it on, idk if that is relevant or not.
