For a while I've been trying to find a solution to this annoying problem where ghost touches are appearing on screen selecting just about anything; same with the keyboard randomly inputting text without you doing anything. It was very difficult to compose a text message more so at inputting a password until I found this solution from another forum. Here is what I did. I exported the system/build.prop file to my email because Root Explorer crashes while trying to edit it. Basically what you need to do is add these 2 lines at the end of the file: # touchscreen stability touch.size.calibration=Geometric touch.size.scale=100 Once done editing the file, copy it to your sd-card, then open Root Explorer navigate to where you copied the file. Next long press the file and choose copy. Next navigate to system/app and paste it there. Longpress the file to set permissions to same as the rest of the files there. Close Root explorer then restart the phone and you are done.
