Hold your device in your hand, wave it in the air in the pattern of a figure-eight a few times and then set the device back down on a flat surface. Accelerometer Sensor automatically re-adjusts the range of your accelerometer and can effectively calibrate your G-Sensor.

What to do if accelerometer is not working?

Your sensors (accelerometer or gyroscope) are no longer properly calibrated, and require calibration. To do this, they will therefore have to be recalibrated, using an application available on an Android smartphone.

Why is my phone accelerometer not working?

Accelerometer sensor can stop working due to many reason like device drop, heavy shocks, water and bad configuration, just give it a try to fix it. Note: If you can't fix the sensor using this app, that mean you have a hardware problem, and the only solution is to replace the sensor chip.
