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.
Using stock ROM without root, any apps or functions that could set brightness to low for saving battery are either uninstalled or turned off? Any suggestions?
