Screen Brightness issue

My phone keeps turning brightness way down by itself with this message. All temperature readings are fine. Any ideas?
-- Note III, TapaTalk II, AT&T is Horrible--

I too am having the same issue, however i believe that my issues is slightly different from yours. I noticed maybe about 2 days after i purchased the phone that mostly anytime I am using the browser, whether it be Chrome or the stock browser my screen automatically adjusts itself. I went into settings and made sure that the brightness was not set at "Auto" and turned all the way up. I also made sure that reading mode, auto adjust screen tone, and color adjustment were all turned off. I also changed the screen mode to dynamic and I seem to still have this same issue. I read on another forum for T-Mobile users that there are a lot of consumers experiencing this same issue, not sure if carriers are doing swap outs for the phones as this may not be related to a HW issue but rather a SW issue.

That sounds exactly like what I'm experiencing. Except I work outside, so when it does this it's impossible to see my phone. If you get a chance the next time this happens can you go into settings and open the brightness slider to see if you also can get this error message to appear? That seems to be the only place I find the message, it doesn't just pop up or anything. I too have checked like 10 times to make sure all the other display settings are correct, like automatically adjust tone and such. It sucks that auto brightness cannot be fine tune with the slider like it could on the note 2. I'm finding it very strange that instead of adding to features of the Note 2 to make this phone better in every area they chose to remove some great features leaving me wishing I did not upgrade.

It sounds like thermal throttling. LG phones have this, in particular the Optimus G and G Pro. I haven't had the problem on my G2 yet. It's designed to lower the brightness and lower the cpu speed in order to keep the phone from overheating.

True my LG Optimus G pro does this but there is a way to turn it off in the system menu accessible from the dialer. I have turned mine off and the phone no longer does this and has not gotten hot or anything. Wish there was a way to do this on the samsung as my S4 exhibits this same behavior.

I'm thinking about getting a Note 3 today so I'm hoping can be shut off too. I shut it off on my G Pro and the G2 doesn't do it, which I'm very thankful for since I work outside as well.

Since we're on this subject, how often does it happen on the Samsungs? I would figure less often due to amoled not being as bright as LCD.

You may be better served to leave the auto brightness checked when your working outside. When on auto, it gets much brighter when needed than with the brightness slider cranked all the way up.

Note 3 automatic brightness settings problems
I have a Samsung Note 3 phone bought in Germany. I have the some strange problems with brightness settings too. Typically from time to time the phone screen just get too dark. Particular in economic mode the phone can get from time to time very dark and even setting auto brightness to +5 does not help.
I was using before both Iphone 5 and the first Samsung Note and some other phones and automatic brightness control was always working fine. In my new Note 3 the brightness is jumping sometimes suddenly.
JVogle: You can adjust the automatic brightness by pulling slider up or down. It can by set from -5 to +5. But in my case this thing do not help so much. Particularly this is a bigger problem again in economic mode.
This is rather a software issue, because when I switch to manual brightness it stays constant all the time.
Anybody knows how to cure it?

This is so annoying. Gotta wonder if it's a bug in one of Samsungs ****ty features causing it to happen so much. Even without brightness all the way up it happens

You have a different phone than me apparently. Also a different issue, as I'm referring ONLY to manual screen brightness setting. I would expect fluctuations with auto brightness. I've never had a device fluctuate when manually set to a desired % though. I also can't believe they removed the ability to adjust slider with auto brightness. Sadly the only thing better about this phone than my Note2 is the specs. The software and user experience has been sub Note2 for me in every aspect. I will most likely be switching back to the Note2.

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.

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 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.

Set sun brightness mode?

I think it's just not possible to manually set highest brightness of display in Android 9. But is there any way how to set it via some app or edit something?
I know there is toggle for adaptive brightness, but setting it for full brightness will just make display cca 70% of possible brightness. The 100% brightness is on only when sunlight comes to the light sensor. When I use Note9 for flying DJI drone on sunlight, I want to have 100% display brightness for that 10 minutes of flight. It's just sooo annoying that I have to use separate flashlight - shining to the Note9 sensor to have full brightness on sunny day in shadow. Otherwise, just manually set brightness is not enough for flying and reflections are stronger than display...
Thanks for ideas!

jd14771 said:
Really easy fix..
- pull down notifications
-expand all notifications
-expand brightness settings by hitting the downward facing arrow (brightness settings)
- select "show brightness settings on top"
Now you can bump up your display brightness for those 10 minutes. It would be absurd to spend any more time on an app selection
Click to expand...
Click to collapse
Thanks, but I can say I'm kind of poweruser So again - When you set brightness manually all the way up, it's just 70% of possible brightness. It still uses light sensor to detect light and if you face the sensor (still manually on full) towards the sun, ONLY THAN you'll get 100% of hardware brightness.

Haha, okay... Maybe somebody else with Note9 and experience with Samsung's "outdoor display mode" may know. Anyway, see the attached image, maybe you get that point from other user...

I've use to do it on my Note 2 this way, I don't know if it will be any help. I know what you mean, the extra brightness is there, you just want to be able to switch it manually.

There are a number of apps in the 'Playstore' that purport to do what you want.
The one that I use is called 'High Brightness Mode', it's a free app and enables you to place a widget that can be used to manually crank up the brightness to beyond the 100% shown by the brightness indicator,.
According to the instructions, it goes a lot higher if your device is 'rooted', but nonetheless works on 'unrooted devices too.

It seems rooting is the only way how ti get 100% brightness...
@jd14771 - here is the sample:

To achieve what? I want to have 100% brightness MANUALLY.
No adaptive. No automatic. No light sensor.

jd14771 said:
could have just tried turning on adaptive brightness. from what i read outdoor mode wont trigger unless you are on adaptive brightness at exactly 100% brightness.
if i had to guess its because the max brightness in the sun causes display burn in- so to limit the issue they only allow adaptive brightness to go past the 75% software max
Click to expand...
Click to collapse
Yes, but as the OP was trying to point out, the software absolute max is actually about 15-20% below the hardware absolute max capability.
This can be enabled by tweaking the sys file related to brightness, to rewrite the specific line, you need to be 'rooted'.

jd14771 said:
I have yet to see you provide instructions on how to do that.
regardless you dont need to be rooted to get the extra brightness, conditions have to be met in order to save the screen from burn in abuse. There are tons of people reporting burn in from the outdoor mode. it only make sense that only adaptive brightness can take the screen into danger territory, probably has safegaurds built in to avoid damage to this $1000 phone. so far ive provided more insight than anyone.
Beggars can't be choosers.
Click to expand...

Once 'rooted' there are a number of 'Magisk/Xposed' modules that can be installed to push the brightness beyond what's available by default.
Did you want me to detail the 'rooting' and install process?
If you do a quick 'Google' you'll find a number of threads on 'XDA', 'Reddit' etc, going back a number of years which are the focus of the OP's issue.

The brightness slider full to the right, regardless of the adaptive brightness setting is as bright as the phone gets.
How do I know this? Because e-ticket apps such as Ticketmaster and mobile payment apps like Samsung Pay go full brightness when showing barcodes, and there is no difference between manually set 100% brightness and 100% brightness when set by Ticketmaster and Samsung Pay.
The problem you are facing is caused by those who wrote the software that displays the video feed from the drone.

incorrect, the sun brightness method as well as youtube and the photos app does go brighter than the screen is normally i have max brightness past the line adaptive brightness off performance mode turned on with brightness set to 10+ specifically which boosts the brightness past the normal brightness as well as vivid mode but still not the same as the brightness you get in youtube apps or on the photos app, the xperia 1 and xperia 5 does this too and i thought it was specific to them.

Question Auto brightness too low

Hello, 3 days ago I bought oppo x3 pro. Phone is awesome, but auto brightness works very bad... It keep decreasing screen brightness to very low level.
I never seen something like that, Samsung S20 works much better, well, even realme x50 works normal. To use phone I had to disable auto brightness. Is there anything like adaptive screen brightness, I read somewhere that samsung by the time learn my preferences, and keep good brightness. Tired this with oppo for 3 days, but seems it doesn't have that option.

If it is the same mechanism as in OnePlus (not sure about it) - then the phone will "learn" after you manually set the brightness to proper level. Give it 2 weeks.
Btw. Rydzyk in avatar, hope youre not the real one

Real Tadeusz here
I was teaching for 3 days, but without success. Will try for a week now
thanks

Try clearing system cache and data in the relevant apks.
Test the light level sensor to see if it falls within an acceptable range.
I use manual brightness control almost always; doing so saves battery, retinas and sanity.
It also reminds you when it's too bright and your frying your display.

Same here. Helped me out with Lux Brightness and set the minimum brightness to 30. Works fine for me.

To me in Realme 8 it seems to have learn a minimum value for auto brightness instantly, I just set a minimum a little above of the default level (It was very low), and the phone remember that level onwards

well, mine surely isn't 'learning', it keeps defaulting to the lowest value, which is waaay to low.
Are there any alternatives to Lux Brightness that you know off?

What happens to me is that the default auto brightness deactivates itself when it wants, and reactivates also when it wants, very annoying. So I deactivated manually the auto brightness and tried Velis Auto Brightness, this app is a little complicated but works quite well, just you have first to understand the app itself and then tweak a little to your convenience. It has a little bug in Android 11, the notification of lux and % of brightness screen disappears after some time but doesn't affect the app itself. Take a look https://play.google.com/store/apps/details?id=com.velis.auto.brightness
