I bought the D2 pad from Big Lots. Does anybody know an app that calibrates the g sensor? My tablet doesn't seem to work in some tilt games like Temple Run and Mutant Roadkill. It won't tilt left or right but the screen does rotate. Does anybody else have the same problem with their D2 pad? Is there a way I can fix this? I would take it back to get another one but they don't have anymore in stock and I took off the apps that came with it.
