The problem with the truth is that it is relative to the enquirer. It is true for some that it is now daytime, for some it is night, for some twilight and for someone off planet they can see that each is true and false and not something they can decide or experience and hence know.
Turning off the Auto brightness does avoid the problem, but is is being officially looked at.
However after 5 days mine has been stable for since yesterday evening. So hopefully there is some algorithm that I have managed to force into a useable function.
I should wary of speaking too soon, roll on the evening when the light dims.
I have the same issue, and I only have it since the last update.
All workarounds I read here, are working for a day at the most on my Fairphone. The next day it re-appears at some moment. Especially, switching auto brightness off doesn’t help because my phone now adjusts its brightness even when I switch auto brightness off.
It’s annoying because it prefers to happen in dark on the go when I quickly want to look something up or call someone. Having to go to the settings and to find the brightness slider in the dark in order to see something at all, is a bummer.
I really hope they roll back this “improvement” as soon as possible.
The sensor takes a reading of the incident or refracted light and this is used by the Auto Brightness algorithm to decide how bright the screen should be.
There seems to be a problem with the interaction.
a) The ambient light sensor has been reading
b) The Auto brightness setting is over-riden somehow
Thank you! I just applied you trick and it seems to work.
And now to something completely different. I tested you trick at 10:00 am. That gives me enough light to see every corner of my room. The Sensor reads 0. IMHO Fairphone needs better sensors.
