I have got my M2-mini from china (U model), and in general I am very happy with it (high value/money ratio).
I have OS 188.8.131.52.A and everything work fine except a sound from the device camera.
when I change the camera modes or when I switch back to the camera from the gallery, I hear a sound like mechanical clicks (2 clicks - one after another).
It is not a sound from the speaker but comes from the device itself.
Any Idea what can be the cause for such a sound?
