dankhan because i was having these issues with some devices what i did was set up a button in my game settings users can press if they what to calibrate tilt when they press it I then tell user to tilt in direction and I check the beta and other sensors and with a global variable i set if it should change the how tilt works. most users dont have to do this as it works correctly, but for the one that do it helps most of the time. hope that helps I tryed to explain it the best I can
