Display brightness low in dark environment [Update: SP21.B.048.20230215]

Whatever it is, I think it would be improved by replacing it by a setting where you can simply specify the minimum and maximum brightness values automatic brightness can use. It would cover all the individual needs, of everyone.
(Assuming those values correspond to reality, i.e. 0% is “screen off” (and not just some arbitrary dark value), and 100% means backlight at full power whatever the cost.)

You’re right! I never noticed it on my Pixel 3. Not sure why though. The Pixel 3 can only go slightly brighter than a FP4. Maybe OLED is what makes the difference? When I enable it on my Pixel 3 I can’t see much anymore, the minimum brightness is already quite good. I hope the FP5 will have an OLED. In dark mode it’s so more pleasant to look at it at night.


For me, too. Its to dark. Ok, you can set the brightness manuel up… but this not very nice… :frowning:

I see that the expectations for display brightness are different. - For me now the automatic brightness is giving automatically my preferred brightness for the first time after this update. - Before it was far too bright all the time.

I have set my display to extradark for nearly all conditions (have to switch that off for use in direct sunlight) and I am glad, this change was implemented.

Hello together,
the "Extra Dark " option seems to work like an overall “darker” function.
Why not putting a slider here? Instead of this button
Left → F… dark (Slider left + extra dark active)
Right → 50% (As an anti “Fear of the dark”)
So the Main Slider or automatic adoption in the pull down can only choose between these two values (proportionally) and is then (hopefully) suitable for each mankind (womenkind also of course) :slight_smile:


Hi @Yasen_Tomov, whatever you do please do not increase the minimum brightness, I find it is already sometimes too bright when viewing a page with white background in a dark room.
Cheers :slight_smile:

Hi @Yasen_Tomov, whatever you do please allow each user to set his/her own minimum/maximum values.
It’s definitely too dark for me, even with glasses on.


For me too…
I just got out of the car in the dark and you just can’t see anything. In one hand a bag in the other the FP4. It feels like I’ve set the slider 20 times higher, but the software doesn’t remember it exactly. The dark setting is so useless because even in total darkness it’s just way too dark. I don’t mind you building something like that. PLEASE build a switch to turn this feature on or off. Or a minimum brightness or something. Find it really bad that a feature that wasn’t there on Android 11 is built into Android 12 in a flash by a few people who complain.


Well, there is already a switch to make this problem even worse…
I insist, allowing to set upper/lower limits is the only way to satisfy all people, the Darkers and the Brighters, before they start slugging it out… :roll_eyes:

Me again. Being curious by nature, I tested the output of the FP4’s brightness sensor, and noticed it doesn’t fare too well in dark situations.
In a fairly (but not totally) dark room (only one small nightstand light burning) it indicates total darkness, unless you turn the selfie camera (that’s where the brightness sensor is) towards the light. If the selfie camera can’t see the light directly, the sensor reports total darkness and the screen goes dark, darker than (for instance) the (white) walls of that room. :slightly_frowning_face:
This could just be a bad calibration, since the camera does manage to take photos at that illumination level. Unless it’s a hardware limitation (low resolution sensor) in which case it can’t be fixed.

Anyway, if you don’t want your screen to arbitrarily switch to the darkest possible setting, keep the selfie camera well illuminated! Wear a headlamp! :crazy_face:

Or just turn off automatic brightness and set the brightness to a value which is best for you. Then you also don’t have to fear that it will change without your consent. :wink:

Sure, but automatic brightness is very useful, especially when you move a lot between very differently illuminated places. I admit I’m too lazy to swipe down twice and change brightness each time I move from one room to another…
Probably like the vast majority of users, else this thread wouldn’t exist… :grin:


Just to add:
There are three sensors to the right of the selfie camera, the camera itself isn’t used to measure the brightness.
They are hard to see, just directly below the cut for the upper loudspeaker. The left sensor is the proximity sensor, the middle one the lux sensor, I think.
You can see the corresponding spots in the display here, for example:

Frankly the ‘modern’ solution is to recognise that there is NO one and only solution. Thus, if we could all set a min and a max and the stupid phone went between we might be happier as the phone becomes usable. Much as all the evangelists will all complain about this post, all I’ll say to them is this, “Why do other makes not have the same issue?” It’s possible and FP have got it wrong. Sort it.

I’m about to repeat myself again :slight_smile: Phones can already adapt to your preferences for almost a decade. The technology behind it isn’t that advanced, in relative terms. The phone can learn what you prefer. There is no need at all to set some values by FP or by yourself. When you adjust your phone a few times, the phone will learn.

Are you sure about that? I tried obscuring various parts of the screen searching for the sensor(s), and IIRC coming from the left, I only had to cover the selfie lens to get the reading drop to 0. IIRC, I’ll check again (but it will have to wait till tonight!).

Mine is kind of stupid. It didn’t learn anything so far. :frowning_face:

I’d like to think it will learn one day. I am manually correcting it each time, err, each evening, but so far it keeps stubbornly switching off the screen backlight as soon as the room isn’t brightly illuminated. :frowning_face:

Yes, I can confirm this - when covering these sensors, the display gets darker, eventhough the camera itself is still uncovered.

Perhaps if you removed your sunglasses you’d have more chance of being less patronising and might see the world as it is instead of through those FP4 tinted ones…

I’m about to repeat myself too. “It does not work on a FP4” Seemingly if you need it to work you have to buy a Samsung or other make right now.

I apologise for the personal nature of the gibe but I’m tired of your constant put downs and attempts to undermine people’s genuine concerns.

You may give “Velis Autobrightness” a try:

This app will install itself as accessibility extension, adjust the brightness based on the light sensor of the device and you can set a permanent additional brightness, so the display will not get darker as you want to.

As I understand it, the idea is that the app will not control the background light but it applies a filter on top of all other content to darken the display content. So you first disable the auto brightness of Android, set a desired maximum brightness manually and then use Velis Auto Brightness to adjust the content brightness using one of the provided adjustment curves. Since it uses the light sensor of the device it works quite well, at least when I did a quick test with it.

There is also an extensive documentation for it: Velis' thoughts: Velis Auto Brightness manual
