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.

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

Ambient display is useless

I found that ambient display is useless.
I was thinking that whenever I got notification, the ambient display will lit the screen and then OFF ... then lit ... then OFF.
You know, kind of asking attention.
It is NOT.
It lit ONCE, then OFF forever, until I pick up the phone (of course).
The problem with this, if I leave the phone on my desk for quite long, I won't know if there was notification arrived, unless I pick up the phone.
So, what's the use of this ambient display?
Damn, LED notification would be much useful!

So you can either see the notification come in first time when it lights up. Or you can quickly pick the phone up to see if there are any notifications without it fully waking up.
LED is easier though!

I prefer they don't lit it on and off constantly because it is distracting when you are in a meeting and it drains your battery. Though having an option would be nice

Yeah, I agree it is a useless battery wasting feature (though the impact to battery is minimal). Thankfully the LED can be enabled with Light Flow even though that is flawed as well since the app will randomly get killed and the light won't work.
Ambient Display would be perfect if it flashed continuously until you check it and if it worked in priority mode, which it doesn't if you have priority mode set up like the old silent mode. If you don't want your phone making noise or vibrating but still need to see notifications it is pretty worthless.

you are dead on sir.

I was told Google is moving away from using led notification, but yet they designed a phone? with one built in but totally useless at this point. Hopefully the next update will address this.

Mine flashes continually until I check things... Every ten seconds or so. It is wonderful... Not sure what is up with your guys' one time notifications...

ambient display is alrite.... It doesn't work that well though. It does not consistently work when you pick up the phone. I would much rather have them activate the LED since it's already there.

in all fairness, Moto made the phone, whether for Android Silver or whatever other reason, it wasnt designed ground up with Google or originally planned as a Nexus.
I like ambient. Works great for me. and being an Amoled display, only the pixels being used light up, so battery is minimal

users report otherwise.

Does the device wake up from deep sleep for it? If yes it sure does suck a lot of battery. Especially if it is supposed to flash up in intervals to remind you of the notification.

I just tested it... it flashes up every 30 seconds or so. As soon as as you click on it the screen is on without any delay. So I guess it screws your battery hard by making it wake up each time? It would mean that as soon as you have a notification your device would wake up every 30 seconds.

I can't get Lightflow to work at all. Do you need a kernel that has LED support?

Rooted and use root access for the LED activated in Lightflow.
Lightflow screws up ambient tough. It constantly flashes as if it has an notification, even if it only shows the clock. This WILL kill your battery in my opinion...

Led notification will drain batttery fast?

I actually like it more than Active Display. Active was much more sensitive to movements which for really annoying.

I don't know what settings you set to make it do that.
Light Flow doesn't do that here. Cooperates fine with Ambient.

I know there are people (Lightflow Dev) who are working on getting the built-in led working, and I think that's great. I wonder if there are any devs working on making Ambient Display more useful...? I'm going to shut off the Ambient Display today and mess around with an app I used to use on the Galaxy S called NoLed. It puts dots or icons on the screen and could notify me of anything... might be the ticket here.

Sick of samsung's bad displays

So my display after being replaced 2 times in 6 months started flickering. My phone is very hard to be turned on because of the green flickering.
I just want to upgrade to a S6,S7 Edge or non edge. i just want to know if they have the save problem with displays ? I want to have a phone at least 2 years, can you recommand me a phone like that ?
I was just considering switching to a iPhone even though i prefer android on phones ... o how are S6,S7s displays ? Samsung still have the same problems?

Samsung improved a lot on screen quality in S6 and after, so you should be okay

Wow that's amazing. Been using samsung s5 exynos version for the last 1yr. Never had that kind of problem till date. And it have the same display as snapdragon version. And on comparison I found that this is by far the best display out there when compared to other brands.
Maybe perhaps you might be having a faulty unit from the begining.

I have the same problem here with the display and it's not a software problem (same by original os 6 and same by cyanogenmod 14).
After the temperatures are under 10 C. i can't open my s5 with home button i must do it over the power button.

Using S5 for more than 28 months still I have not faced any issue. I just had to buy new charger apart from that not a single problem and yes I mess up with my phone so much but I still working and no display failure yet. And also I have dropped it many times, it still refuses to die.
You are just having a defective model or some internals of the phone are messed up. Because Samsh*t produces one of the best displays..

Its not a good sign. Try disabling your light sensor. Even then if you experience such a problem than it means that your flex cable that attaches the screen with the motherboard needs to be changed.

Hi,
Yes and expect the same problems with the following generations. It's an amoled screen thing. The green colour happen when there's a colour displayed on the screen for a very long time (for example, I have a green on my screen of the size of my keyboard).
I think a solution to this problem is to set the display to turn off after 30s (it saves battery too) and maybe, if you're using a custom keyboard, change the colour from time to time. Use the brightness of the screen to a lowest which would still be comfortable to you (and auto unticked).
This last tip alone is enough to prevent greening. My flickering happened after an incredible fall (it had a tempered glass so the screen was safe). The flickering showed green what it had in memory.
Samsung has a 2-year guarantee for its products so you shouldn't worry for that period of time. Problem not solved, replacement.
Best of luck

The funny thing is i already did "by mistake" all the tips you said and still have this. Never dropped the phone though. This problems seems very big though, i expected a burn in to be the biggest problem, but to have flickering at a level that i cant turn on the phone. I wanted recently to switch to a Nexus 6p, but knowing that it uses Amoled too, its a bad ideea. So the only "solution" is to switch to IPS screens? (btw i want a phone that holds on for at least 3 years)

In my research thus far, the AMOLED screen technology is to blame. When the display circuits get old or damaged, they don't sustain current at low power settings. In LED screens, a back light controls brightness, but AMOLED screens send current to each pixel for brightness control. If the circuit is damaged, or any corrosion has built up inside, this could attenuate the current below the point required to sustain light flow. I see this problem with some LED and CFL lights on motion sensor switches. Just enough current goes through the motion sensor to keep it's circuits active, and that current causes a flicker in the light.
With the screen though, since the problem is only resolved when you increase the brightness just a bit above minimum, it seems anything that lowers the display power (auto brightness for example) will cause it to flicker if this setting gets too low. I also noticed that before the screen locks on timer, it dims to low power for a few seconds and flickers as a result. There are apps that attempt to resolve this by putting a translucent black screen over your desktop and apps. This keeps the power up on the pixels but adds a black overlay, kind of like a screen filter. You can adjust the darkness if you need it to save your eyes when reading in the dark but it doesn't help save power any. They also require a rooted device, which could void warranties. The reason for this I believe is because apps are supposed to operate in a way they don't intrude on each other, and a filter that lays over your screen does in fact alter the output of your display rendering. With the added security concerns of these apps possibly collecting screen shots and sending them to another site, I would avoid this. Best to use a physical screen overlay you can put on or remove as needed as long as it doesn't interfere with your touch screen options.
Ultimately, these devices were meant for replacement every 2 to 3 years so if you're like me and you like to make your investment last, best thing to do is apply any work around you can come up with. A repair shop may be able to wipe the circuit boards down with a solution that clears away corrosion, but it won't repair any weakened pixels. I'm still using a Samsung S5 G900F
- And i finally got this fixed. it sounds like the reason for this is that since the latest update your phone cannot decide whether to use hardware or software back light settings. I managed to make the problem go away by doing this:
Go to settings >> system >> About device.
Find "Build number" and click 6 times fast on it.
You will then get the message saying: "You are now a developer"
and then go back to Settings >> system >> Now you will see the "Developer Options"
Now go to Developer options >> Drawing Section or Rendering Section >> Find "Turn off hardware overlays" or "disable hardware overlays" >> This will force the phone to always use GPU for screen adjustments. no more flickering.
but If I turn the brightness ALL the way down, it still flickers like crazy, however, if that's the only time it'll do it, I consider that a win.

Auto brightness

How's your auto brightness working? If I set mine to auto it just dumb. In a dark room the screen just gets dark. I mean, it's always in a lower brightness setting.
Can't use it in auto.

Same. I never usually like autobrigtness for the reasons you mention. I remember an app called Lux which was great at the time, as you could customise the brightness levels per lighting environment and was much better at managing brightness automatically.
For now though I generally keep my brightness around 20-30% indoors, pretty much 100% daytime outdoors (or ill put autobrigtness on then) and around 0-10% in the dark/bedtime - sometimes with reading mode on too

Surely it's something to be fixed... Unusable for now
