I have a superpad 3 tablet that I purchased off eBay new about 5 or 6 months ago. My problem with it is the touch screen is hard to maneuver. It takes several touches to get it to do what I want and when I try to touch a specific thing , it always touch the wrong thing and it's slow and frustrating. I tried calibrating the screen and it showed all was well but it is still hard to scroll or do anything with it because of the touch screen so I don't use it much plus can't do any Google apps because it is recognized an china or unknown device.
