iPhone: calibrate motion sensor - does it work?

If the motion sensor on your iPhone is not working correctly, you can calibrate it using the compass app. We'll show you how it's done.

iPhone: calibrate motion sensor

• If you start the compass app, the calibration will start directly. If not, turn iPhone off and on again.
• Tilt and rotate your iPhone so that the red ball runs along the edge of the ring.
• This means that not only the motion sensor, but also the gyroscope and the acceleration sensors are recalibrated. A certain inaccuracy can still remain.
• Note: Keep your device away from electronic devices. These can influence the motion sensor and thus make the calibration less precise.
