Auto brightness doesn't go to 0% in dark environments (minimum is 30%)

Hi, my #fp4 doesn’t go lower than 30% when unlocking my phone at night. I was expecting that the phone would learn this preference, but after a week it still doesn’t go to 0% at night. The screen of the #fp4 can’t really go very low anyway, with auto brightness at a minimum of 30% it’s not great for my eyes :nerd_face:

I’ll contact support to ask if this can be improved. For those who want lower brightness than the phone default, Android 12 includes an option to go down a notch further (not sure if it’s Pixel exclusive though). So maybe in the future that will come in handy.

In iodé, for example, with the lastet fix to this issue, it’s woking well and as expectetd.
In a completely dark room, goes down to 0%

Moving from a bright via a darker into a bright and completely black area:

When I compare stock FPOS and Calyx on two FP4s directly, CalyxOS can be set considerably darker.

So a “simple” software fix seems possible :+1:

Hi together,

my wife and I are proud owners of the new FP4 and enjoy it hardly.

However, the minimum screen brightness at night is a bit too high.
We would appreciate it to make the screen even darker.

I saw the topic regarding the the minimum screen brightness of the FP3 and the problems which occurred with the automatic brightness adjustment.

Does the FP4 suffers under the same problem, which is why the minimum was set so high?
Or is it possible that you simply adjust the minimum via update?

Thank you very much
Rick

Welcome to the community :wave:
I’ve moved your post to this existing topic.

So far there sadly hasn’t been any update on this and the most recent OTA didn’t improve things as far as I can tell :thinking:

Just as a quick example of what could maybe be possible (excuse the awful Nexus 4 camera quality):

The FP4 on the left is running Calyx A12, the FP4 on the right FPOS A11, both with Night Light disabled and at their lowest possible brightness setting.
Even if it might not be completely apparent, there is a significant difference in minimum brightness, so there is the possibility for improvement.

Not really. The minimum brightness has been deemed to high for some people. There was an attempt to lower it and at the same time adjust the automatic brightness. This failed in that the auto brightness made the screen effectively turn off with the lower settings.

The only resolution was to undo the update so it is back to how it was.

It’s a personal issue, unless soem phones are different. We have two FP3s and an FP4 in the family and everyone thinks the lowest brightness is fine.

So no it’s not high, it’s the usual default. Whether it is personal or your phones is debatable.

Apparently there are apps that can override the Android 11 settings but it may require rooting the device.

Maybe try to turn nightlight on, I have it always on on the FP3, because for me its also to bright (was the same already on the FP2). Its not perfect, but I would say with nightlight on its better.

Hmm usual default for the FP4. However, It’d be nice if one could change the default. I don’t think that our both devices are somehow brighter than the default ones.

I’m currently not planning to root the devices, as some apps require it not to be so.

Thanks for the suggestion. I already have the nightlight on. I can confirm that this feels better but is still too bright in our eyes.

While playing with the brightness slider, I observed, that the first half centimeter of the slider doesn’t change the brightness at all. Maybe someone can confirm this behavior.

Here is a site that offers ‘solutions’. In the first 10 only one requires rooting.

Haven’t tried any of them ?

I can confirm that behaviour, but it’s the same on all 3 Android devices I have access to at the moment.
My guess is that’s there to account for thumb thickness :smirk:

@Rick Just downloaded

It adds a ‘greying filter’ works fine but I don’t like it

Changed my mind, I do like it :slight_smile: It removes some of the contrast

Greying filter? Like the bedtime mode in Android?

There’s no ‘bedtime mode’ in my A11 on FP3. There a Night Light which tints amber but no grey option and no adjustment.

Maybe you could point your discovery out to the OP?

It’s in Digital Wellbeing, which should be part of a default Android install. It creates a black and white filter as well. But the brightness is only slightly minimized by it IMHO.

Ah! Found and enabled it.

There’s a black and white mode and maybe the default amber but no manual change to the depth of brightness/contrast to normal colours.

So it does have a black and white option which maybe useful to some

UPDATE: Problem

I had the same issue using the app I mentioned as occured with the previous FP3 updatre where the screen went dark in the day.

It seems the app disbled ‘autobrightness’ sort of make sense, but then for some reason, maybe it was on and then put in my pocket, the screen was dark ‘black’ and even in the sun would not adapt.

I had to go somewhere vcery dark to be able to see anything when I swiped down from the notification bar.

Ok manged to get brightenss and uninstalled the app.

What fun?

I am another new owner of a for and I can confirm that the problem is still there.
The automatic brightness control goes only down to somehow 30%. Using manual control I can go much lower. So this looks like a bug in the automatic and there will be no app as a solution
