iphone 5s bubble level can not be calibrated
Got the iPhone 5s and testing the new bubble level but it is off by 3-4 degrees.
On a flat surface if you stand the phone up right with the bottom of the phone on the surface, I get a perfect 0 degree with green, but if you stand it on the right side of the phone (other side of the volume button) I get 3-4 degree off. Shouldn't I get the same results unless the gyroscope sensor is off? The compass calibration doesn't seem to correct the problem.
iPhone 5s, iOS 7
