Is Samsung Galaxy Tab A, Samsung Galaxy A7 or ZTE Blade L3. On any gyro at the simple demo is not working. On all devices SystemInfo.supportsGyroscope returns FALSE. Input.gyro.enabled = true in Start() is set.
UPD. The answer is found. The gyroscope in these devices was never. You have to use the accelerometer, but now came the question how to know the angle of the device?
