Is there a way to tweak the behaviour of the auto-brightness backlight? At the moment it correctly goes up to full brightness in sunlight, but it doesn't go as dim as I would like under artificial light. At home, after dark, under electric light, I can manually turn the screen brightness down to the minimum level, and it's still bright enough - the auto setting is much brighter than that(although clearly much dimmer than it is in sunlight, so it is doing something).
Can this be tweaked? Failing that, is there an easier way to control the brightness manually - something I can keep running all the time, and which doesn't require the stylus to change the setting?
Try GLight

Thanks, I'll give that a try.
I find Lumos to be more stable and reliable

Ok I havn't tried either of them before but I just installed G-Light.
After a bit of config. it's ok. You need to give each backlight number a wider setting.
Otherwise it'll just flip back and forward in brightness.
So far G-Light is proving rather dissapointing. The phone's built-in "Auto" setting works well, apart from the fact that the brightness doesn't go low enough in dim light - in particular, it manages to choose a good level and then stick to it. G-Light, by contrast, keeps changing the brightness up and down all the time.
I think the notion of having absolute brightness bands may be the wrong way to go. You really want a set-up where the threshold values are in different places depending on whether the light is getting brighter or dimmer. So, as the light fades, you cross a threshold and dim the screen - but when the light goes slightly back up over that threshold, you don't brighten the screen again until it gets significantly higher than that. That way, regardless of the light level, the screen brightness will be steady unless the ambient light level is changing a lot. If you use single threshold values then whenever the ambient light happens to be very close to a threshold value you will always get the brightness going constantly up and down.
Edit: some of the things Lumos does (like averaging across multiple readings) sound hopeful, though. I'll give that a try.

Let me know how Lumos is.
Yes as I said earlier you need to widen those settings.
For now I have 5 set to 0-81
6 set to 82-200
8 set to 201-600
10 set to 601-1000
All the rest are disabled by setting the values to -1 to -1

Lumos is also proving dissapointing. It's partly the fault of the hardware - the sensor seems to read 0 even in surprisingly bright light, so the app has no way of telling whether you're at a light level where backlight 1 is appropriate or a light level where backlight 3 is appropriate - both read 0 on the sensor. (This is probably why the default auto option doesn't go below 3 in the first place).
As for Lumos, the author needs to realise that perception of brightness is actually based on an exponential curve. That means that all of the values between level 1 and level 5 are somewhere between 0 and 80 sensor reading. The graph interface is useless for editing custom values with that level of precision - it's trying to squeeze over 2000 values into less than 800 pixels of screen space, and the pixels are tiny! I think you can edit the values directly in the settings.txt file, but that's fiddly - there should be spinboxes, really (as with G-Light).
In any case, you don't want to be editing the values directly! What you want to be doing is taking the phone out of your pocket, looking at it, and thinking "hmm, the screen is too bright at the moment" then adjusting the brightness to whatever level is comfortable for the current ambient light level. The programme should then interpolate the curve that you want, and progressively refine it each time you decide it isn't quite right and tweak the brightness.
I haven't tried to Lumos program yet, but I've been using Glight for a few days. At first I had some issues with it but then I realized that you have to turn the auto light adjustment off in settings first. If not, they'll both be fighting against one another.
Also, you have to set your thresholds pretty carefully as has been already stated. Mine is set to go bright only in bright outside and lowest in a dark room with no light at all.
1 0 to 5
3 10 to 799
8 800 to 2500
I've got mine set low for better battery life and the screen is always readable to me no matter what anyway.
Also, if you're using a the snap on rubber protector (I got a T-Mobile one) it will interfere with the light sensor. I just got one and the lighting is all over the place now. Time to order a full body screen protector.
GLight doesn't seem to work for me. keeps crashing, and the settings don't seem to save at all.
I don't want a sliding scale that Lumos has since i don't think the light sensor is all that accurate (sometimes thinks it's too bright and sometimes thinks its too dark). would rather just have a few settings (pitch black setting, super bright setting, and in the middle) as shawndh suggested.
i have the verizon tp2 - not sure if this might be causing some of the glight probs.
Hello all,
I'm just curious as to how this feature is supposed to work. I have my device set to automatically adjust while it's on medium brightness and I've noticed that the brightness jumps from low to medium frequently, especially when I'm on just one page.

I believe it just counts the number of white pixels on the screen on the omnia. this is why it jumps so much. The only way to prevent the jumping is to set the birghtness on low, with the auto setting off. Even on medium or high it jumps when the page has a certain % of white pixels. Like for opening the browser its really annoying however on low brightness the colours are really nice and its just perfect for me. Its just too bright on med or high brightness for my preferences.
But the way how the "feature" itself work I have no clue. Maybe a light sensor. But the jumpiness is caused by the number of white pixels on the amoled screens, and occurs only on samsung devices I believe.

Thanks for that explanation, Marvin
Sometimes when I'm in a dimmer area, my display will be so dim I can hardly see it. This doesn't happen in brighter areas.
For reference, it is far far dimmer than brightness setting 1. I have the watch set to auto brightness and ambient off.
Anyone else seeing this?
Yeah, it seems that the 360's auto brightness setting is (at least sometimes) pretty aggressive in low light conditions.
Same here, and I hate that. I always have to go into the settings when the room light is dim, and switch off auto brightness and change to the 1 setting.

I'm almost positive it's a bug, the low brightness of 1 isn't too bright for very dark situations and the dimmed mode is simply too dim.
I'm pretty sure auto-brightness should turn on at level 1 (if it's dark) and then go to the ultra-dimmed mode before the screen times-out just like in normal brightness.
I don't think I've seen this bug happen in the daytime though, so it does seem like a bug at brightness level 1 only
Any solution to this problem? Drives me crazy.
Thanks

Try Smart Brightness for Moto 360. This application allows to set auto brightness with a minimum brightness to avoid a dimm screen on dark situations.

With adaptive brightness on my screen frequently (every 20 seconds or so) changes brightness slightly even when the ambient light isn't changing. It's very annoying when reading and most noticeable with light backgrounds.
Is this a common issue or does it sound like I have a defective sensor?

Same here.
So annoying I had to turn adaptive off.
Seems to be when I move, probably changing sensor and it's too sensitive. My head mush change/reflect light on sensor
Anyway it's so distracting that I can't use adaptive brightness, except when pitch dark I can set to 0% adaptive to have lowest light output

Yep, reminds me of a disco strobe light!
No issues here. I actually think the brightness swing is much better than the OG Pixel XL. I can just leave the setting at 50%. On the OG XL I'd have to turn the brightness down in the living room with lighting from 1 lamp and a tv because it'd be burning my retinas.
I installed Lux Dash and disabled "adaptive brightness" and let Lux handle it. You can go into the profile editor for Lux and setup different presets for different levels of light, you can also adjust the min and max allowed brightness and even setup how you want it to adjust brightness (fade, only set on unlock, dynamic, etc)
It has really made this screen amazing and even helps with battery because most the day my screen doesn't go above 15-20%

I've been fine here with the Adaptive Brightness too. Doesn't change too often at all for me.

I installed Lux also and that did the trick. I assume the sensor is fine since Lux uses it with no problem. It's odd that some of us are having problems and others aren't but it doesn't seem to be a sensor issue.
Having this same issue any solution?

I'm curious but how exactly is it reacting for you? Are you just sitting in bed with the lights on and it's still adjusting up and down the brightness? Cause that's what I'm doing right now and it hasn't fluctuated at all. If I put it on the bedside table it'll brighten up and when I pick it up it dims but that's it.
Sent from my Pixel 2 XL using Tapatalk
Yeah that's too much fluctuations don't you think I mean on my iPhone x or any other iPhone that I have have used so far I never could tell that the adaptive brightness was on but this device does it in an obvious way and way too frequently that im not sure anymore if this is what it's supposed to do I chatted with a Google agent and they forced quit ambient service thing from system apps and I think that still didn't resolve the issue. I will pop up in a vz store tomorrow and check out if their display devices are doing the same

I'm curious to hear what the tell you. Lux has helped me a lot bit I still notice it. To be fair I think I only notice in a dim or dark room with the TV on but this is the first phone I've used where it's noticeable to me. I'm also wondering if this is how it's supposed to work or if there's something wrong with my phone.

What I described was too much? Sounds appropriate to me. If there's extra light on the phone, I want it to get brighter. If that light goes away, I want it to get dimmer. Now if it was happening with no light changing then I would be annoyed. I keep it at 29% with Adaptive Brightness on and it's not too dark in outside light and not too bright in pitch dark.

I'm having the same issue. I'm on my second Pixel 2 XL so I don't think it's a sensor problem. I only notice it in lower lighting but it's really annoying when it happens. Haven't seen this issue on any other phone. Im trying out Lux now and set it to only adjust when waking up. There were similar issues when Lux was set to Dynamic.
Ever since Google thought they knew better than everyone else and got rid of auto brightness for adaptive brightness, it's been trash for me. I CONSTANTLY have to raise it in dark rooms and lower it in bright rooms. AKA, I might as well turn it off because I'm manually adjusting it every time anyway.
All in all, it's terrible.

You know Adaptive Brightness is a mix of manual and auto brightness right? I remember auto brightness actually having the issues you're describing because there was no way to adjust it if it was set. If you have Adaptive Brightness on high enough, it should be bright enough in dark and bright situations. I believe people's issues are that it adjusts too often or the opposite, it's too dark in light rooms and too bright in dark rooms.

Yeah I know it's supposed to be a mix somewhat. It's supposed to match the setting you set to whatever the surrounding brightness is relative to your brightness setting.
That's exactly WHY it's trash in my opinion though. It's a flawed methodology. I don't want it matching my setting relative to anything. I want it low in the dark and bright in bright rooms or the sun to be legible and not more. It tries to do some meet-you-in-the-middle garbage and it just doesn't work well.

I found the threshold for the lowest brightness in pitch dark with Adaptive Brightness on to be 29%. That should be dark enough in dark rooms and outdoors it's readable to me. What percentages have you been trying?
Mines doing the same thing. Did anyone work out whether it was hardware?
I used a sensor app to see what light was reporting, and it was stable. I can only assume it's a bug.
For those who aren't sure - if the screen is on, and not moving, without any changes to ambient or direct light, every 20 or so seconds the screen will dim to a warmer colour, and then 20 seconds later will brighten to a whiter colour.

Yeah I had a feeling that's what people might be experiencing.
To add on to this thread, this is also occuring on my gen 1 Pixel.
Ever since I upgraded to 8.1 the adaptive display will brighten/darken while the phone is sitting still in a constantly lit room.
I also appear to have lost much of the granularity in the brightness selecting bar. The first 25% or so is as dim as it goes, and only after that does it begin to alter the brightness. Previously it would begin around 10% on the bar.
Additionally, the logic behind adaptive brightness seems to have gotten worse. I previously left my brightness setting always in the same place, and no matter where I was it was either dim enough (at night) or bright enough (during the day).
Real unhappy with this update.
Hi everyone. I haven't seen the related kinds of thread so I decided to post it. My device model is G3223.
tl;dr: It's too bright at minimum brightness during nighttime.
So during daytime the screen looks perfectly fine, no problem reading under the sunlight. But when night comes the problem arises because the phone can't go dimer, which means that the phone is still quite bright compare to my other devices when I am trying to read in bed even though the brightness is set at minimum.
Does anyone also facing this issue? Or if it's device model related?
I have the G3221 and I have the same issues. But I found 2 solutions to the problem. (well kind of) if you disable automatic brightness ? setting it will be way too bright. After enabling the auto brightness you can lower it even further. But if it still feels too bright, you can change the white balance settings to 255 which will lower the brightness even further without actually affecting anything. I hope it helps a little. ?

Problem solved. Thanks a lot. I don't know why Sony doesn't allow us to change the brightness to the real minimum point without using automatic brightness.
For white balance I set my phone to a warm colour. For (255,255,255) [r,g,b] the screen looks too cold though, and it can also lower the brightness. I am currently using (255,147,0) so it's at least better than the original setting (0,0,0)
Speaking of warm tones, sony also hides the blue light filter in the actions section which is almost invisible and many people don't even go there. You cannot enable it otherwise. They need work on their stuff.
You can use the Twilight app to use the phone at night without stressing your eyes. It works for me when I'm reading things. ?
And of course you can use this to lower the intensity of the screen's light if not the overall brightness.
Hope this helps.

Thanks for your advice. As far as I know, apps such as twilight only draw an overlay on the screen, which means it actually doesn't affect the brightness in any ways. It just seems to be darker.
In contrast, decron04's solution can actually decrease the brightness. Don't know why Sony doesn't allow users to minimize brightness without using auto brightness.
