I moved your post to this topic.
Please note you are not reporting an issue here officially to Fairphone, this is only possible via their customer support. The forum is rather a user forum.
I removed the serialnumber.
Btw your system is not up to date.
In the meantime my FP5 does not adjust itself to 0 in a dark room and only to 6%. Havent tried resetting brightness as suggested by @k3dAR in another topic I can live with this 6% and can still adjust manually to 0.
Still I assume a third party app might not be needed when using, dark mode and extra dark and maybe even night light as filter. @Renat did you try?
I just want to check if people still experience this issue. I still do. FP support said that within 2 weeks the auto brightness learns your preferences. This is of course true for most Android phones such as the Pixel. But this was never the case with a FP device. I still have to fight the auto brightness, especially in low light environments. There is no noticeable auto learning.
So, has anyone seen the brightness go to 0% in low light environments after manually adjusting this for 2 weeks? I’ve been doing it for more than a year now…
I am still experiencing the issue.
I own a FP5, bought 6 months ago. When in totally dark rooms, the brightness stops to some % (I don’t remember the exact value). I set the brightness to 0% and after one second it returns to some %. When I put the brightness to 0% again, the second time, the value seems more stable.
Hi. I had this prob 18 months ago and switching off DC Dimming solved it
DC dimming is switched off for me, but I still have the problem described by @UPPERCASE
Adaptive brightness could indeed be more buggy with DC Dimming and randomly jump in percentages. But this is a different issue. See topic title.
Latest patch, still have this issue
I performed a factory reset and it seems to work again like it did during the last few updates of Android 13. It now consistently goes down to 0% in a low light environment. Of course this doesn’t fix the issue for people still experiencing it. Maybe something went wrong with the upgrade path to Android 14? Also with DC Dimming it still seems usable. I’ve been testing for a week now.
I have a brand-new phone with the same issue. It’s simply unusable with the screen that blinds me every time I’m in a dark room. I don’t know if it makes sense to do a factory reset; I bought the phone a few days ago.
Is the brightness going to 0%? Because if it does than the problem is that the 0% is not low enough for your eyes. I have the same, the FP screen is at the lowest setting still quite bright. But I don’t think they’ll fix that. Best is to contactsupport and explain the issue. Maybe one day they will fix it properly, but likely they will shift their attention to the FP6 by then.
The brightness remains fine at 0% with Extra Dim enabled, but it occasionally increases unexpectedly. This seems to occur because the light sensor detects the screen’s reflection in the room. I notice it’s changing when the screen displays lighter colors.
It may help to disable DC Dimming. That enabled adds some bugs. But you’re right, the auto brightness is not very well developed on FP in any case.
I cheered too soon. The problem is back, and even worse. At night the auto brightness is now at 60% 
Hallo,
I tried to ignore the problem for a long time, and keept pushing the screen brightness back down all te time. fond this les of a struggle than switching to manually, its only a struggle in low light.
now it looks like the problem has gotten worse over time on my FP5
now the screen literally burning my eyes. “me hissing like a vampire in sunlight” joking.
Lowest auto brightness setting:
my phone dit switch back to 61% after unlocking and random during use.
looking around in the setting how not really make themselves clear what tey suppose to do.
i did’t noted a difference when on or off.
i dit mark them blue.
Extra dimming, i see the difference, just wondering why ther is a switch for it and not just part of the brightness scale.
DC Dimming, thanks to Ingo
sunlight mode same question as extra dimming.
and so far i did’t notice any difference in the (mis)behaviour of the auto brightness changing the settings.
what’s the default setting for those?
i dit the reset suggested by @k3dAR:
The brightness dit jump back to 0% directly during the klik on the reset button, and dit stay there all the time writing this post.
thank you @k3dAR!
now wondering if it the problem will get back in 2 days like @UPPERCASE and @ManuelF postet. “Touch Wood”.
Dit someone here already get a proper anser from Fairphone support? is it on ther tasks list or they still say the bug was already solved…
Greetings
Tom
Hi guys and gals,
since day one I have an annoying issue with my FP5: The lowest brightness on “auto” seems to be 28%.
What I tested with no effect:
I could slide it to 0% manually, only to have it back on 28% again when unlocking.
Has anyone got a tip for me?
Kind regards
Have you already tried this fix/workaround?:
I have not - after trying at this very moment, it seems to have done the trick.
Kudos and thanks - that was a small tap with large effect!
Just for clarification, did the bug came back or that fixed it?
I’ll observe for a couple of days and get back to you.
