I was on a custom 4.3 rom running on old bootloader. I then
updated to 4.4.2 rom but my camera is not working only a black screen and giving
me a warning message " Camera failed" and once that happens
the whole system lags. I've read around that it could be a hardware
problem but when I switched back to the 4.3 rom the camera is working
smoothly again. I have tried 3 different 4.4.2 custom roms but same issue persists.
My question is could this have anything to do with my bootloader? I am planning
on flashing a stock 4.4.2 firmware with the new bootloader to see if that helps but what
worries me is if this doesn't help then I have no way anymore to go back to
a 4.3 firmware where my camera still works. Can you help me point to a solution
to this problem? Or which stock firmware I should flash to test if my camera
will work on that firmware.
