问题
I have a Huawei P9 Plus smartphone running Android 7.0 and I have written an App which collects sensor data. For the gravity sensor Android is telling me that the accuracy is unreliable. For the magnetic field sensor I'm getting medium accuracy. For all other sensor I have high accuracy.
Is there a way to calibrate the gravity and magnetic field sensor?
