Brightness issues

I have this weird brightness problem where I have it at 50% and it would randomly dim and brighten like crazy. I tested at 100% brightness and it also dims and brightens. Obviously, I don't have it on auto brightness but it sure acts like it.
Anyone with the same issue? Is it a defect? I just got the phone today and I'm afraid to exchange it to have the same problem again. I really like this phone. There's always a friggin issue on a new phone. It's ridiculous.

I think is a software problem. Lollipop still have lot to fix. Mines look the same. Can be a display minor isue. Not sure, but for me this phone doesn't have the best brighness at all. But I love this phone better than others for now. If you came from samsung phone, there is a big diferent in brightness. Post some screen shoot. One in a white background, and the other in a grey one. I will post the same and you tell me if something is diferent. Sorry for my grammar. Is not the best !!!!?

In Q&A is a thred call DPI Change. Try that, but reed carfully. you'll need root for that.

I appreciate your input but I don't know how the things you mentioned would help me in my case. I would need to do a video in order to see the problem instead of screen shots. Dpi change will do nothing in this case as well. You may be confused with the issue I have.

Well I try my best. As I sed could be a software problem. DPI is a resolution thing, can help a little. Also you can link a video to see exactly what you talking about. The reson I ask for the screen shoot is becaus I can probably see a differences between your brightness and mines. Hope somebody can help you on that.

Auto brightness issue

Has anyone noticed an issue with the auto brightness of the note 8 ? It seems it doesn't get adjusted efficiently! Sometimes it's too dim and sometimes too bright, that's so disturbing

It's really funny, it worked after I installed an application called lux lite, that's unbelievable.. I need to install a third party application on a 1000$ cellphone to get such a basic function working. Thanks Samsung !

I believe you are wrong about this. The auto brightness is adaptable, in the sense that you can set it manually wherever you want in different comditions and it will learn your preferences and interpolate. I actually find it very flexible.

I find that is not doing such a hot job at learning my preferences. I keep having to manually adjust because my phone thinks it knows what I want. It's annoying.

do you mean that it has a new functionality that has not been in old phones? I have the Note 4 and it works like a charm, but the note 8 auto brightness works strangely, when I'm in a room with low brightness the screen light goes so dim that I can barely see anything!

Ive experienced the same thing, I have to do a screen lock for its auto brightness to work correctly

Hi,
(sorry for my English)
Your message was one month ago but I reply just in case some people have the same issue.
You have to call samsung about your issue. I have done that there are 2 months ago and Samsung are going to change the settings only if they have lot of complaint about this weird behaviour of the note 8, S8 and S8+.
The new settings of the auto brightness is "smart" but often it's more like "lost" than "smart"... :/
I adked to Samsung to give 3 choices for the settings of the auto brightness for the user instead of 2:
1) manually
2) auto "smart"
3) auto "not smart" => so the phone adjust the brightness depending only of the light sensor.
They told me that my proposition can be integrate only if they received lot of complaint.

Seems to come with last update
I can confirm am having the exact issue..
Brightness doesn't seem to auto adjust. Even after a reboot. The issue seems to come during the last update - the update where now we can have video lockscreen and animated AODs.
Hope this is resolved soon.

I don't recall having issues on the last update, but I am on the latest CRG1 now and it's working fine on my N950F.

I ran the sensor tests, and it seems that more than the lux sensor is not responding ...
My heart rate sensor seems to work on a hit-or-miss basis..
SpO2 working fine though.

Try and reset your usage pattern and give it time to learn your usage. You will have to adjust the slider for your preference while its learning. I'm on the latest oreo and have no issues with it.

Reset phone to factory settings..
Issue persists!!

Hello Guys,
Yesterday I received the August 1 Update on my note 8.
After the update, I confirm the matter has been tackled
Screen rotation, auto brightness all working fine now.

That's strange. My auto brightness worked fine up until the latest update. It is the August update that caused the problem for me.

Actually, providinf an update on the matter.
Some days later, situation came back to square one!
Not working:
Light sensor
Heart Rate sensor
Proximity sensor
Gyro sensor
Magnet sensor
Accelerometer
Just fingerprint sensor seems to be working fine.
I was on a trip in Malaysia and was at a Samsung store. They told me this is a very common issue and easily solved by 'software update' but when I went on to the service centre, they denied me since my phone was bought in different country. Phff

If the next OS update doesn't resolve this then I would recommend that you take your device to a Samsung Service Center

Anyone got their unresponsive device working back again ?

[solved] Adaptive brightness broken in pie

Does anyone else have this issue? Every time you lock/unlock the brightness auto adjusts again (and it adjusts pretty low)
So even if I manually set it to 100% and lock/unlock it will be down to 25% again. Doesn't seem like it's learning at all

Seems like it takes a lot of time to learn. I don't use it anyway I prefer having control on it

Seems like a bug honestly, because it goes TOO LOW. I tried to lock the device several times to see if the "learning" of the slider improves, but it still goes back to the same spot... I'm gonna keep it deactivated until they fix it.

Android Pie has AI in basically everything and it learns for you, just keep adjusting the brightness manually and in a few days it'll know how you like your brightness and adjust it for you.

I care about to go low! And now I can't go below 19% with Adaptive ON, it's to high for a dark room.

Actually I've been reading similar things about this on the pixel so it might just be the way it is. Might take long for it to learn. I read someone say it's always fun when he first unlocks it

And I found this link of people claiming it is like this the first few days until you train it better

Yeah it could be the new implementation of the AI, I'm gonna use it for a few days to see if it gets better

This has started happening to me since yesterday. I've been using Pie for a month now (December update). What I've noticed is that it goes down to about 25% every time I cover the brightness sensor with my finger (usually when watching YT) and it stays there no matter what. It's pretty annoying having to always adjust it like that. Using "Sensors Monitor" app I see that the sensor is working correctly so it's a software "feature".
Any suggestions on how to mitigate it besides using "Velis Auto Brightness" app?

How do we know its 'AI'? Has it 'adapted' for anyone till now? That brings us tk the question, what was wrong with Auto Brightness in Oreo? Just because there's piece of code that's new, doesn't mean its versatile.

Yeah, and some of us would be fixing what was intentionally broke. Interesting, what would Android be without the community working as the underdog?
Oh, and AI (its Computational Intelligence) is the new cheaper, efficient corporate slave working to enslave the many.

Auto brightness to low

Hi i am on gloabal stable rom and i have noticed that the brightness in low light goes to low and iff you change it manually to slightly higher it wont stick and after the phone screen is turned off and then back on the brightness in darker areas is to low again. Most android phones on Pie i have had have adaptive brightness meaning it will adapt to how you set it in each environment but on Miui i think it is different and it is also called auto brightness rather than ambient brightness. I am rooted and i have tried a couple of magisk fixes but nothing changed and in dark area it is still to dark and this is a big annoyance for me and i think it should an easy fix. Maybe someone know where the brightness values are located and can explain how to change this manually so it does not go so low in dark areas.

I have the same problem with 10.3.1 mi 9t pro

I don't have the problem anymore I moved to lineage

Somebody on forum said that you have to train your adaptive brightness. Every time it is too low you bring it up with slider and after few times it should learn your preferences. I didn't yet try this, but I will...

Usually on Android it works like that but on miui its called auto brightness rather than adaptive brightness and didn't work in the same way.

Any news on this? Does it work on MIUI 11 / Android 10 better? I love this phone but this issue is really annoying.

I'm on miui 11 EU it works perfectly.

Low Brightness Flicker (LineageOS & Stock too?)

Hi, sorry if this was posted before, but with XDA moving to XenForo, search seems messed up, i did several searches and nothing comes up for "flicker" in this whole Pixel 4 XL Forum...
Has anyone else dealt with the low brightness screen flicker? I know it can't be just a bad phone, since i just bought three pixel 4 XL phones and they all exhibit this same behavior.
They are all running LineageOS (Official builds) so I don't know if this just affects the ROM or stock as well (although I've read it might affect stock phones too elsewhere).
It makes the phone pretty difficult to use in very low light situations, the screen will constantly flicker (more noticeable on darker backgrounds).
At first I thought it was just the Opera browser (as that's what I prefer), but it's operating system wide... Apps like "Darker" help.... because you can crank up the phone brightness and use a filter to dim the screen.... but it doesn't get the top & bottom menu/buttons, so those remain like spotlights in your eyes with that workaround.
Just curious if anyone knows whats up with this... it's the only phone I've ever seen this behavior on (and i've used Pixel 1,2,3 XL phones all with Lineage, and a myriad of other devices back in the Cyanogenmod days.... I've never seen a screen flicker issue like this).
Thanks for any help
edit / update-
the pro version of "darker" app works to fix this.... you crank the phones brightness to 100% and with the pro version you can dim the rest of the interface.
hopefully this helps anyone else suffering from this HUGE flaw (again i don't know if its just LineageOS or not, i didn't run stock on these except to unlock bootloader etc)

Hi,
I've seen it once and solved it by switching off smooth display. Not a real solution of course, but I never really noticed the difference between 90Hz and 60Hz anyway.
