My old HTC M8 with a 5MP Front camera is clearer...!
I expected more from UMI S2 Pro... its a abolut dissapointment... And the OS... WHAT A BS**T..
It looks like they want to copy APPLE... no Freedome at all anymore.. unorganized launcher...¨
Even the Widget has been restricted to 3x3 when there was a 4x4 Widget option.. i.e. Calendar
Basic ROM is not with bugs etc!!!!
Anyway please provide some pictures of your screen issues. Also take pictures in bright area with front camera and provide samples heret.
Please use latest Basic ROM.
This is exactly the same ROM with removed unwanted apps and unlocked launcher.
If you have any bugs on this ROM you will also have same bugs on official ROM.
If you want use Basic ROM please install this ROM from scratch. Use SPFT and flash complete ROM with firmware upgrade option.
