FP5 Adaptive brightness unusable after update

The auto brightness changing rapidly in dark rooms without any sense. Didn’t experience any of that before the update (FP5.TT3L.A.106.20230918).
Deactivating Auto brightness is a workaround.

What kind of behavior are you experiencing? That sometimes the brightness goes up for a brief moment? I noticed that with the older update as well. But in my case it was always in a low light environment and I’m not sure yet if it’s triggered because the light sensor was aimed briefly at the light source in the room or the screen’s light reflecting back into the sensor due to having the phone too close to an object. It doesn’t happen in a total dark room.

Maybe you can share some more details? Especially on how to reproduce it.

Have you extra dim enabled? Turning off removes this bouncing for me in dark rooms.

Still I see in low light (not dark) rooms that the brightness repeatedly adjusts almost to zero (like in real dark room) and it does not learn that I manually change this over and over again as its too low in my eyes.
Difficult to reproduce, as its difficult to reproduce the exact same light conditions.

I do have extra dim enabled, I’ll leave that disabled next time.

For me in dark rooms , brigthness at zero and than turning on extra dim, brightness starts pulsing between 0-8% back and forth non stop for at least 30 after that I turned it off, it stopped staying at zero, enablng extra dim again, its starts pulsing

So if you have extra dim on regularly I guess you would have noticed already?

I enable extra dim only in the evening/night, then I don’t notice this issue. At least, not yet. I notice and brightness increase only in low light environments, so far. But it’s very brief.

No I didn’t used extra dim. Someone on r/fairphone expiring the same after the update:

It has been occurring since the update and only in darker rooms with a brightness between 0% and 20%

I dont follow reddit. I think best is to contact support… Overall difficult as we already have quite different descriptions here…

Does this mean just dropping down and staying or chaning up and down

I’m experiencing the same issue. Usually in dim conditions, but sometimes in not so dim, auto brightness changes brightness up and down quickly without any obvious reason. Sometimes darkness can rise from the lowest point up to ~30% or even higher, making it too bright for the conditions - and then fall back, just to rise again, and so on.

It happens both with extra dim enabled and disabled.

I had that too with a FP5 I had in test. I noticed it especially in Telegram topics, didn’t find any reproductible method.
