My replacement 3D has begun randomly and more and more frequently, quit responding to any input except the power button. i can wake the phone and have to pull the ring more than a few times to get it to unlock. After its unlocked, it quits responding and begins to act like its possessed, randomly zooming/scrolling, closing this window or that one, clicking links.....ect. Basically just freaking the eff out. Anyone have this problem and know of a fix? I have insurance but last time took about three weeks for this busted replacement to arrive. Just curious. Thanks Peeps!
