Adaptive Brightness Issues

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.

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.

Display Dimming/Tint Issue

Hi Guys,
This is my first post so apologies in advance if this is not the correct place to ask this question or if I don't particularly explain the issue I'm having properly.
Something incredibly annoying and frustrating is happening with my display every night. I notice that around 7pm each evening, my phone will go from a nice crisp looking display to one with a yellowish/warm hue. It's as if my blue light filter is on but when I check, it's definitely off. I turn it on and nothing changes with the display, but when I turn it off, the display goes back to how it previously was. I am currently using the adaptive screen settings, auto brightness turned off, and blue light filter turned on with the customer schedule of midnight to 9am. I've also tried turning off blue light filter altogether but still run into this issue. It keeps happening every so often in the same night even after I've "corrected it" using the method of turning on and off the blue light filter.
Is this to be expected with the adaptive screen mode? I love how vivid and bright it is during the day, but despise the yellowish tint at night. Could it be possible that the blue light filter is somehow turning on by itself even when I've turned the feature completely off?
I appreciate any assistance. Samsung tech support was not particularly helpful and told me to go to Costco where I purchased it from and return it.
Thanks,
Cam

Have you tried configuring the color balance in the Display settings?

Thanks for your reply. I haven't tried that yet because I figured it didn't matter what setting I adjust it to as the display would automatically change in the evening anyways.

It's strange that even you already turned off Blue Light Filter, it's still making it dim. I find the dimming helpful since it doesn't strain the eyes at night. You could try reflashing the software for the phone.

I agree, but I would like for it to be turned on later such as 1 hour before I go to bed.
At 7pm PST this evening (about 15 min ago), the screen regained it's yellow tint again. I turned on the blue light filter, then turned it off to get it back to how it was initially previous to 7pm.
The Samsung support rep asked me to factory reset my phone, but that didn't work either. Would that be similar to flashing the software? I can certainly give it a try but was just wondering if the factory reset essentially did the same thing. I'm really not sure what this could be.

It's the custom schedule for the blue filter. You can change it in display settings.

This does not fix it. I have my custom schedule set to enable at 8:00 and disable at 8:01 but it still turns on at 7pm.

Finally figured it out!!! Go to Google Play Books. Open a book and tap the screen to find the letter A. From there go to settings and turn off the night light. Whew! This has been bothering me for months!! Hth!!

I'm having the exact same issue except I've turned off/on the blue light filter a million times and it doesn't fix it.
I also don't have google play books installed so it's not that. I've tried messing with every "display" setting but nothing fixes it.
My phone did this same thing a couple months ago and when I woke up the next morning, the display was back to normal. Now it just did it again but even though its a day later, my display is still all messed up (not as bright and crisp, has a yellowish hue to it).
Anyone got any other ideas or does this sound like some kind of hardware issue?

I had the same problem specially when I go to sleep at my dark bedroom, my phone is Samsung Note 8, and I just found the solution. Turn your phone to the otherside, look at the main Camera, mine has two cameras, a flash, and a rectangle black sensor at the end. I covered this sensor with a thick black paper that I found from a brochure, taped it in place, and Wala ? no more screen dim.

WOW

Occasional Color temperature / screen tint change

Has anyone noticed their screen occasionally looking slightly warmer (more yellow) than usual? Not sure if it's after the recent update or if its always been there..i think its the update.
SM-960F here
Display mode - Adaptive. But I'm comparing just the notification shade.

That is probably a result of the blue light filter. It turns on automatically at 7 pm. You can change its settings in display

Thanks for your reply but its not that. I checked.

Do you notice it in certain apps? There's also a "video enhancer" feature under "Advanced features" - try turning that off to see if it changes anything.
The one other way I notice the screen temperature change is in bright light - under Brightness, you can control the "screen mode" - adaptive is default, which means it automatically switches between cool and warm depending on what you're doing and where you are (in the sun, for example). Take a look at the settings there, because you can customize it a lot.
Edit: I see you said you are on adaptive, so you probably already looked at these. Have you tried making it a set setting rather than adaptive?

Try turning off auto brightness.

Do you guys face these display issues in your devices?

A70's display treats dark pixels as if they were completely black, and turns them off instead of dimming them. Which leads to difficulty and inability to see dark things properly + distortion of the displayed thing (especially on the lock screen) because a lot of pixels are turned off.
The device has already been updated to the latest software version in Samsung's customer service center.
Here are some pictures and a video showcasing the issue: http://imgur.com/a/w9tLNAJ
Test your device at night or in a place with dim lighting.

I know how AMOLED works, it's just that it's not working correctly. Check out the pics in the link, the screen changes the colors, and turns off way too many pixels.

You have more issues besides pixels turning off. Looks like posterization as well.
I don't have those issues with mine.

If you know how it works, then take your phone to the service centre as probably you have the warranty.

They told me there was nothing to worry about, so I guess that's that.

yes i have these problems too on the lock screen majorly i think its a step by the software to save battery. I had these problems on my old note 5 too.

Happens to me too.. Dark grey colour turn pinkish on lockscreen..

Find X2 homescreen colour temperature changing automatically in the evening.

Hi Guys,
The home screen colour temperature on my Oppo Find X2 changes to yellow (warmer tone) automatically in the evening everyday. Both Nature tone display and eye comfort settings are switched off completely (no schedule has been set as well). The weird part is that the lockscreen's colour temperature is absolutely fine, its when I go to the homescreen I see this issue all through the night. It goes back to normal in the morning. I've tried factory resetting couple of times but it didn't work. My phone is on Coloros 7.1 with June security patch.

My phone screen color changes while using the chrome very ofen. And even while i am typing this in chrome.
And scrolling on oppo website also changes color from warm to cold.
Anyone has answers
