Hello, I have problem with the backlight of my xperia z1 compact D5503 and hope someone knows some solution or what the problem could be.
The backlight stays always at its minimum level, which is OK for inside but not outside.
Light sensor and proximity sensors are working..
With an app like lux or similar I can dim the brightness below factory min, but not higher.
The file sys/dvices/leds-qpnp-f5141e00 leds/wled:backlight/brightness shows different values when I change the brightness values. Max is 4095. The file max_brightness allows 4095 and the file max_current allows "15".
Installed is the latest Lollipop ...270.
The screen was replaced with a spare part (two screens here, both have the same effect, so that I do not think it is hardware, even though the supplier is the same for both displays)
Any idea what it could be or what to do to check if it is hardware?
Thank you for your help.
