I have Sony Xperia Z (C6603, 10.7.A.0.222) and the brightness level is stuck at minimum after update to 5.1.1.

I have tried:

  • - sensor test - light sensor is OK.
    - set brightness via ADB (settings put system screen_brightness 200) - didn't work.
    - using brightness control apps (like LUX for example) - didn't work.
    - factory reset - didn't work
    - downgrading to 5.0.2 - didn't work, still the same problem

Using stock ROM with root, any apps or functions that could set brightness to low for saving battery are either uninstalled or turned off. Any suggestions?
