Hello Forum, I have a THL T200C mobile phone with Android 4.2.2 installed. Recently (since VR is coming in sight) I've noticed that my gyroscope is not working properly. The tilting to the front and backwards is doing the oposite they should be. Tiltilng left and right is working fine. Now here comes the tricky party. This was measured with the built int G-Sensor checker. When I download a sensor tool (Sensor Box for Android for example) that shows the gyroscope values without any issue. Tilting left-right-up-down, all fine. So I've downloaded Google Cardboard and I can't use it because when I turn my head left, the picture turns right. If I turn it right, it goes left. So clearly it is using the built in g sensor that is not working. Do you have any idea or sollution how to fix this very annoying error?
