I notice this when I'm outside and the sun is hitting the display. Doesn't happen all the time though.

Maybe you set the screen mode to Adapt Display ?

No Everithing is off. Energy saving, Adapt display. Auto Brightness...

How about Auto Adjust Screen tone ?

Brightness in the dark

I have turned off auto adjust from the main notification menu and I have my phone set to standard on the display settings and my phone still dims when their is a lot of white on the screen, when I load google chrome and in games (emulators). Has anybody had the same issues? I've seen also, but I'm not sure, that the processor still run at 1,458 Ghz, not at 1,89.

There's still a setting you need to turn off in the display options, it's just above the high sensitivity checkbox that let's you use the phone with gloves (I don't remember how it's named in English but it basically means auto tone).

It's the "auto-brigthness" and it's uncheck. Perhaps it's a problem of my rom. I'm on stock rom, just root. Or the solution may be to change Kernel. Those who have custom rom/Kernel, have you this "problem"?

Is under display settings , something with "tone"

I don't think it's a problem with options. Many users have this problem. I've try many and many options but still have bad results. But you, have you also this problem or not? If yes, changing Kernel must be the solution or not?

I think this happens if you've enabled Adapt Display in display settings. Try switching it off.

Has anyone got a solution to this, I have had this phone 2 days and the screen jumps up and down in brightness and I am sure I have turned off all the auto settings.
One minute the whites are nice and bright next they turn grey or cream then back to bright white.

Could someone with a Note 3 check this

Thinking of buying the Note 3 but really wanna know how bad the smearing issue is cause i bought the Galaxy s4 on launch day and couldn't live with the smearing issue ( my girlfriend also bought a Galaxy s4 on launch day and still has it..she didn't think the smearing was annoying..i hated it )
Could someone with a Note 3 try both things explained below on low brightness
1. Download zedge and search for black wallpapers..then while scrolling thru the wallpapers..do you so smearing..purple glow on the grey background in zedge between the wallpapers?
2. Choose a black wallpaper as background and install nova launcher...then on the homescreen set a widget with some grey in it like the stock music player widget and scroll between the homescreens...and also with some icons on the homescreens?
On the Galaxy s4 doing the above there was a lot of smearing..purple glow visible even after the fix from samsung cause they only fixt it in the samsung framework

I tested Zedge.. Yes there is smearing.
But when you uncheck Auto Brightness Smearing is much much better.
Auto Mode is very dark. In a dark room it gets darker again..I recommend manual Brightness 30 - 50%. Then its really fine.

The purple smearing effect is probably just because the greys blur when moving and they appear purple. Entirely normal and probably same on all phones.

Jep. Black = Pixels are off
When you Scroll the Pixels need Time to activate. Thats the Price for real Black

^^ Ditto, I don't find it annoying, I didn't even know about it until the OP mentioned it.

Ive seen it in Tapatalk 2 with blue dark theme..
Black background and gray Text..The complete Text smeared..
Now i use the classic dark theme (dark grey background) and all is fine
Dont think about Smearing.. i think you will just see it in darker rooms.

Thanks a lot guys...you saved me 750 bucks, some people don't find it that big of a issue like my girlfriend who still has the Galaxy s4...for me it is an issue cause i like to have a black background and while using a black background with nova launcher..on my Galaxy s4 the smearing issue was visible on the icons switching thru the homescreens..don't want that on my next phone

Had the Note 2 and there the smearing was not present cause while displaying black the lights where still active. Bought the Galaxy s4 on launch day and that was the first time i had the smearing issue cause when displaying black the amoled screen is really off so when switching to another color like grey the lights need to become active witch creates the smearing. Sold the Galaxy s4 and bought the htc One that has no smearing but wanted a larger screen so bought a Note 2 again witch has no smearing issues cause the screen doesn't turn of like the Galaxy s4 when displaying black and hoped the Note 3 wouldn't have it but seems it does unfortunatly

OR you could've installed one simple app that would've fixed your smearing issue on your S4. Your blacks will not turn off completely and will remove smearing 100%.

Tried it 2 minutes ago on my girlfriends Galaxy s4 and it does reduce it for the most part but at a very low brightness there is still smearing unfortunatly
No problem though cause after the galaxy s1..s2..s3..s4 and note 1 and 2 it's time to give someone else a try

Yes the G2 has a very dim brightness on 1% and also with inverted colors in accesibility click the name not the on or off button to make it dimmer grab it about the bottom middle of that screenshot and drag it down untill you match the blue color on the status bar all the way on the bottom... it keeps your colors the same but your blacks are darker makes for an even dimmer screen... have taken it to a movie theater and get no complaints its as if ts not even on

One of the brightest displays I've used no joke first time I turned the brightness up to 100 my eyes started watering no joke.

I seldom feel the need to run the brightness above 85% except outside on a sunny day. If you are an auto-brightness user, Lux is practically mandatory. LG's auto-dimming logic is horrible. It's got a, maybe, ±20% range.

I'm not sure exactly what you mean. If you have auto brightness unchecked your screen will won't automatically change based on your surrounding illumination. If you do check it-it should brighten when in direct light and dim in the dark. So are you're saying it isn't changing brightness based on surrounding light correctly (when checked) or you're expecting it to change brightness not checked?

If you have the screen mode to adaptive display , that might be the cause of it. Go to settings/display/screen mode.
