The iPhone’s Positioning Sensors Were Never Good
Much is being made of Gizmodo’s tests showing that the positioning sensors in the iPhone 5s are off. Not just a little off, but off in a non-trivial way. The gyroscope read 3 degrees off, the compass 8 to 10 degrees off, and even the accelerometer seemed to be inaccurate.
The accuracy seems to be improved with iOS 7.0.3.
