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.

This is a problem affecting a bunch of people. There are a couple threads - For example:

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.

brightness issue
I have tmobile and I've had my phone for about a month and now I notice when it's in standby and I hit the power button to wake the phone the screen is really dim for about 10 seconds or so and then it brightens up. My brightness is on max and the auto brightness is disab

Screen Getting Dim?

My Note 3 is nearly a year old now. I can't be certain, but it seems that my screen is getting dim. It's especially noticeable outside. I have tried both auto and manual settings. Have any of you noticed this? Is it even possible for an AMOLED display to degrade with time?

They most certainly degrade with use. My friend had a note 2 I sold him. Got it replaced under warranty. He put burn in on the new screen in only 3 months. If you run high screen brightness all the time it will do it faster.

Thanks. I do run full brightness often. Hmmmm. Maybe an excuse for a note 4.....

I run auto brightness seems to help a lot

Every time I check auto brightness the screen is way too dim for me

Screen settings/brightness/and such

hey all,
I have a 360, and picked up a R to try out (I like that it looks like a "normal" watch). One thing I have been tinkering with is the screen settings. I like the "ambient" mode on the 360, which I guess makes use of the sensor. With the G, so far, all I can see if on or off. And even with the brightness dialed down to 1, it still seems pretty bright at night. Has anyone found this to be an issue or to address it? I have a little time to decide which I want to keep.
Any other advice for the watch would be much appreciated as well.
Thanks in advance!

With Wear Mini Launcher you can setup brightness below Level 1.
With "SWApp True Dark" you can setup brightness from 0% to 100%.

Thanks, I will give it a shot. Can you automate the timing of the brightness level? So, now when it gets dark at 5pm, adjust?
Thanks again

It has a trigger setup for night but not understand well how it works :
Seem to automatic dark after "x" minutes between "00:00 To 00:00" so you can go dark 1 min after no interaction between 20:00-06:00 I think.

Screen flickering trouble

my phone started flickering (2/3 rds from down to up)
it flickers when i lock\unlock the phone
when the light is set to auto and it gets low , to 10 % or so.
i found that the issue is worldwide with at&t phones,
tried :
solution 1 : wipe cache partition. => didn't work
solution 2 : activate developer mode, turn off "disable hardware overlays" => didn't work
solution 3 : turn off : setting\display\auto adjust screen tone => didn't work
then i downloaded : screen filter , allows you to put light at any percentage you want , i tried even 1%, the screen never flickers when i do the percentage manually.
so i guess the problem is software.

I have the same exact same problem..
I thought I was going crazy thinking it was only me..
I have tried screen shooting it when it happens but when I look at the screenshot in gallery it just shows a clean picture. Like nothings happening.
So weird

Same problem here!!! Maybe it's a hardware issue already, maybe a broken display?

its all over the world :/
the only thing i learned so far, never let the phone heat up, or you this might happen.
no solution yet.

mine started doing this after updating to 6.0.1. it gets really bad if the phone gets cold (on low brightness)

Hi. I just wanna share it. I found in this (xda comment post by some one I forget him for awhile looking for him to say thanks very much) fix for my s5 g900f with latest modem and bootloader. I use RR 7.1.2 rom.
The app is "active screen filter". That save my life.

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 ?
