So I restored my device with flashtool (still .370) and i'm still getting slight lag out issues. It's definitely better than before, but the screen still goes unresponsive and I have to lock and unlock the device in the middle of whatever im doing. Also, ive noticed it registers multiple touches at random moments. For example if im on chrome and my tab is lying flat on my desk I may go from scrolling a webpage to zooming into it, all whilst using one finger. Any help would be greatly appreciated.
