I have bought a Nubia Z9 mini yesterday, and today I upgraded the phone with the ''rom version V4.0''. However, when I start the camera, it does not work and it says ''Unfortunately, camera has stopped ''.
The flashlight also does not work and it says ''Conflicts with camera''.
In order to get rid of the trouble, I upgraded the phone with the rom version V3.67, unfortunately, I have the same problem. I also tried camera applications, and they were also unsuccessful.
I live in Germany. I am looking forward for your email.
Best regards,
Can
