Since last update (Fairphone OS v 1.6.2), auto-brightness adjustment have an unusual behavior.
With auto-brightness adjustment activated, the brightness is just like reseted to very low value between each use, even after some seconds if i turn off and on the screen.
This issue is more visible when the brightness value cursor is in the first third.
Note that after some seconds, the brightness get the correct value (the sensor is working).
I didn't have this issue before. It sound like a minor issue but it is very annoying and make auto-adjustment unusable.
This (new) issue was also mentioned here :
- still not fixed in 1.7.0, not fixed in 1.7.1, not fixed in 1.8.1
- Some users reported that the screen stay totally black during several seconds (until 10 s) before to attempt the right brightness.
