Hello,
Am I the only one having difficulties to use this feature, or is it by design ? For example: in the dark, user input is ignored and brightness stays at 0%. Brightness is 0% after restart and unlock too. I checked the sensor with an app and it seems to work.
(FPOS)
I have the same problems - often the brightness is just too low. Re-adjusting by hand works for some time - but then again after coming back from a locked screen (i.e. dark screen) the screen brightness is very low and on a bright day the screen is difficult to read.
I’m running /e/os on a fairphone 6.
Go to “Settings”, then “Apps”, search for system app “Device Health Services”, open “Storage & cache”, tap “Clear storage” and “Reset adaptive brightness”.
I don’t know if this exists under /e/OS but under FPOS it’s standard procedure for problems of that kind.
Thank you, but I don’t have this app on my fp6/a16
It’s a system app. Go to “See all xxx apps”, then tap the three dots in the top right corner, “Show system apps”
Yes I did it. I don’t have this app.
Ok. Should be a preinstalled standard system app under Android from V12 plus afaik.
I dont have this App either on the FP6 (or FP5). So @PhotoPhil you see the App on a Fairphone with FPOS?
Just checked my wife’s FP5 under A14 and my Motorola under A16, both of them have the app running.
who is your provider and is it the same one for your wife’s phone?
I don’t have it either on my FP5.
The FP4 with A15 (no SIM) has it but FP5 with A15 and FP6 with A16 not.
Provider is Magenta on both phones. Can’t imagine this being of importance.
I had similar problems with my FP5 (A14) and the reset solved them completely. I found this approach on a common Android forum but maybe FP devs are doing their own job?
Alternatively try turning adaptive brightness off, restart phone, then adaptive brightness on again. Allegedly clears stored adaptive information as well.
Adaptive brightness is off almost since day one. That feature never gave me satisfaction. But I don’t know if it’s a bug or an expected behaviour.
For example, in the dark, the brightness goes to 0%. If I raise the level using the slider, 2 seconds later the brightness goes back to 0%.
“Adaptive brightness” tries to learn your individual preferences in any given situation. Sometimes this process gets stuck no longer reacting to your adaptation of display brightness.
That’s what the described resetting is for. It starts the process from scratch again. 
As I’m having similar issues with adaptive brightness, I searched all apps and got no result for “Device Health Services”.
Here’s a screenshot of the results for Device* in all apps.
FP6 A16.
In this case try the other way, if needed.
By the way, is “Show system apps” activated in your search? My phone brings up a lot more results looking for “device”.
You dont have a FP6, have you?
Edit: as confirmed above so maybe we should stop trying to find soemthing again and again that just does not exist (for whatever reason)
Yes, “Show System Apps" ist activated, otherwise Device Info wouldn’t be visible.
”The other way” would be which way?
As written above just deactivate adaptive brightness restart the phone then reactivate.
No I don’t. Do I need, trying to help resolving a commonly known basic Android issue?
