Gyroscope not working
Because it doesn't have one.
Beside you should post in proper thread. This is for ROG Phone 2
You all wrong, the Zenfone Lite has Gyroscope but not all can be used by gyroscope, gyroscope in zenfone lite work with Google Maps when you turn your phone. Here the Specs from Asus Website.
So the point is, not all applications can use Gyroscope, actually other cellphones also have Gyroscope but for other things like compass on map and gravity precision when using 3D wallpaper. If on ROG Phone Gyroscope is used to play games.
Either you can update the software of the phone or in other case you have to reset your mobile, i think this is the solution.
