Internal dust on the glass of camera UMI Z

mirco

I can not figure out how dust can penetrate inside my UMI Z and put up on the glass of my camera room.
I am very sorry of what it happened because the camera turns out to be useless. It's a shame that such an interesting phone has such serious issues
Can you help me?
