On the HTC One M9, the Auto Rotate issue can be caused by one of three things – a defective or faulty Gyroscope sensor, an incorrectly or poorly calibrated Gyroscope sensor, or a third-party app that makes use of the Gyroscope sensor but refuses to let it go for the device to use. The following are the two methods that can be used to resolve the Auto Rotate issue on the HTC One M9.
Method 1: Calibrate the sensors responsible for the Auto Rotate feature
Method 2: Reset the device to factory settings
Follow the onscreen instructions and see the factory reset through. Wait for the process to be completed, after which the device will boot up as though it was doing so for the first time.
