Everything works fine, except for the MIUI camera. G-Cam is still working fine.
I noticed camera error occurred when modifying the build.prop file.

Can someone please help me fix the camera MIUI error while keeping the changes in build.prop file?

Thank you.

I'm use MIUI 10.3.30 on Xiaomi Mi Mix 2s
