Hey guys I have a quick question. I was watching a youtube video in my room last night in complete darkness on the lowest brightness setting and I noticed the brightness would change slightly at random. I also noticed it on the skyrim live wallpaper and also while scrolling thru the marketplace. It appeared that when there were more white pixels on the screen then the screen would get slightly brighter. This doesnt happen in netflix or movies that i put on there so I'm hoping this is a software bug happening in google apps. Autobrightness is not on and i tried all the power modes with the same response. Anyone else notice this or also able to replicate this? Thanks!
hey dude!
I have the same issue! I think it is on purpouse. Some kind a way to save power? Here is my thread about this. Try my country and please give me some feedback. Most of users dont notice this. Maybe because their eyes are not so sensitive?
Oh and also if you switch to power saving mode the brightness change will much more significant than on the other two modes

Really no one of you have this issue?
Sounds like a possible LCD screen flickering problem. It's a problem a lot of LCD display mobile devices have. My HTC Sensation has it.
Here's how to test it: at night, turn off all the lights in your home. Basically, your test area needs to be as dark as possible. Set your Prime to a set brightness, preferably as low as it can go. Open up something that has a uniform color and general brightness throughout, XDA app works perfectly. Go near a wall and point the display at the wall. Start scrolling back and forth through the app.
If your device has screen flickering, you should notice that the light on the wall rapidly fluctuates whenever you scroll.
will try. but i wonder if this is relatd to tegra 3 power saving system? i notice the brightness / contrast automaticly change while watching movies, surfing web and gaming despite off turning off autobrightness
so the question is. is my prime damaged or this is normal? dear xda users please how does your prime behaves?
It could also be a "feature" called dynamic contrast which is an idiotic way of making LCDs look like they have more contrast than they really have. But I hope it isn't, I despise it. Dynamic contrast works like that: during bright scene it brightens the screen, and during dark scene it darkens the screen. It's really annoying (and shouldn't be on ever apart from maybe when watching movies).
ok but the question is. how many of you noticed this issue?

I think everyone.
For youtube don't use eco. It's to aggressive and outside of normal videos apps like diceplayer it is useless.
I hope nVidia and Asus will decrease it or give us the option to disable it. Because i like the eco mode for watching flash videos. Much better than Balance and Normal because it's enough and i can save battery.

No, it's not for contrast. It's for saving energy by decrease the screen brightness and increase the color level. And it's always doing it. What we see are the problem of the technique.
Well if it is on purpose then it is very annoying. The only thing that helps a bit is to make screen brighter.
I hope it is not a defect of the screen.
Was looking for a thread with this issue, I'm also experiencing this effect.
It's also noticeable with the stock browser, seems some powersaving technique. Hopefully they will optimise it in ics or make it an option.
this DIDIM technology is constantly at work on our device. I saw a Ram dump txt(which I don't know where it came from) in ly Astro explorer. I looked at it and seen that DIDIM feature is constantly working and adjusting.

You guys know that it's not the power setting right? It's in the screen setting under brightness. If you set it to auto, it will adjust depending on your light source, if it's all white, it will be bright in a dark room and will adjust itself. Turn it off, adjust manually.
And you know, its not. It sets brightness high of overall picture is bright and dark if picture is dark... Much like dynamic contrast. It has nothing to do with auto brighteness. I tried that first.
But can I believe it was fixed in some update, since no one continues this thread after ICS? I cannot update becouse of unknow SN bug. Waiting for Asus to say either send it back or release fix. Thanks.
Happening to me right now with ICS, in performance mode, docked with charger in.
I've been noticing subtle changes in brightness no matter what performance mode I'm in, and I always have auto-brightness off. I normally keep the device in Balanced mode. It's most noticeable if I'm watching videos before bed, as I have the device brightness near minimum, and any change in brightness is pretty clear. At first I thought it was something to do with BS Player, but I've been using Dice as well and see the same effect. It may be a little better on ICS than it was with Honeycomb, but it's hard to tell.
If this is DIDIM, then I guess there's not much I can do about it besides hoping nVidia/Asus tunes the effect to be a little more subtle. :-/
I notice it, however it only affects me with low brightness/auto brightness setting. It does NOT kick in for me over 15/20% brightness combined w/ balanced/normal mode.
That is still on HC, wont get ICS update until two weeks.
Can also be noticed when canging homescreen tabs, slide it over slowly with your finger on the display (keeping it from flipping), once moved more than 30%, the display dims.
I am experiencing this brightness fluctuation, in all power modes, with auto brightness turned on or off.
Very annoying.

Thing that annoys me the most is that it does it with a freakin live wallpaper lol. I guess the snow falling in the skyrim live wallpaper triggers it or something but it is annoying and still exists in ICS. Oh well, maybe they will tone it down soon... here's to hoping.

I'm running the newest ICS update (9.4.2.11) and it's still doing it. The dimming at 30% home screen scrolling still happens too. i'm pretty sure it's DIDIM
Hi, I see there are more and more mods and tweaks designed to help boost battery life. Any efforts like this are really helpful and I'm glad of them.
The biggest use of my battery however is the screen, how about your phone? We have all tried turning down brightness, leaving automatic brightness on etc. but I really think any significant progress that we could make is through changes to how the screen works. Ultimately, I think perhaps the screen resolution and the Sony tweaks like Bravia are too powerful for the size of this battery to cope. Does anyone think something else may be the problem?
I haven't noticed any difference when turning Bravia off. What else could we do?
I use root dim
Always keep bravia engine off ( I dun find any difference to b true)
And I have a brightness bar in notification drawer to adjust brightness quickly
I didn't know about that app, I'll give it a try now. I notice that when you turn down the brightness to around 30% or less that the backlight completely turns off? I bet that is the real killer of the battery.

I use root dim
Below 10% I cant sew anything
It saves battery coz it decreases brightness
What night mode is that it adds a grey shade
Night mode has no effect on brightness
And dim brightness means battery saved
Odd issue i've got on my Z Ultra, easy to replicate by doing the following, bring up chrome, click the address bar, with nothing entered in the text box, but then type something, an the white box drops down, with search suggestions, I can see the brightness increase on my screen, clear the text box, brightness dims back down very easily by staring at the keyboard while this is happening.. is this a hardware issue, or software related? anyone else notice this? very strange. its like more white content on the screen, the brightness kicks up.
Seems normal from what I notice. If it bothers you, turn off auto brightness.
It's part of Sony's dumb LCD optimization gimmicks
It's equivalent to auto contrast used by TV's and LCD computer monitors
You'll notice your brightness goes down when much of image is dark, and you'll notice the brightness goes up when viewing white images
This doesn't happen on custom roms based on Aosp (like slimrom which I use aand prefer)

Wow this is crazy, I just noticed my phone doing this a couple of days ago, and here's this thread. While I do find this dimming "feature" a bit irritating, it's hard to complain about the screen on this device. It looks so damn good.
This feature is called optimized backlight and you could disable it in settings on android 4.2.2 (correct me if im wrong) but since android 4.3 sony removed option from settings menu and they enabled it by default, unfortunatly you cant disable it unless sony returns this option in new android version or if you downgrade to android 4.2.
Sorry for my bad English
Auto brightness... What happened? It used to just work. You know, automatically. If you adjusted the slider it would snap out of Auto mode and lock to what ever you set it at. Going back to full auto was a s simple as selecting the checkbox again in the quick settings.
I don't know if it's part of Marshmallow or TouchWiz but now the brightness slider controls the automatic-ness of the brightness. So its more like a auto "range selector" or "sensitivity selector" it seems. Its more of a semi-automatic mode.
If you set it to ~50% the brightness will adjust +/- 10% around that setting. But it doesn't seem to just automatically do 0-100% on its own anymore.
Set it near 100% and it'll practically refuse to dim in low indoor lighting.
It also seems to respond to whether or not you're holding the phone. It'll get brighter no matter what (thankfully), but it will not lower the screen brightness until you put it down on a horizontal surface... Kind of annoying if you're reading and happen to walk in to a dim room and you're being blinded by your phone until you put it down and then pick it back up. I have Smart Stay turned off so that's not it.
I definitely prefer the plain old, dumb, just works, auto-brightness that I could snap on and off if I needed. Now its...complicated. Why "fix" what isn't broken. Was it confusing some people?
I tried Lux Brightness control app but I'm not sure it's really what I'm looking for. It's too much. I just want "set it and forget it" Automatic (0-100%) brightness like it used to be.
It's a feature. The brightness slider will now bias the automatic setting toward higher or lower brightness while still maintaining the automatic adjustment functionality. Turn off the automatic setting check-box to accomplish full manual control.
What ever happened to just plain Automatic? I don't want to have to mess with a slider. It adjusted the brightness fine before. I find that now it's either too bright or too dim for many situations and I'm constantly messing with the slider. Whereas before, auto was just auto.
Same problem here... It is very annoying

Interestingly, with my old s3 and now my current s6, when looking at battery usage, the screen was always about 15% and usually the second item in the list of things that use the most battery power. It was what I always loved about amoled. Now, screen is number one and comes in at ~50% after the marshmallow update. I wonder if it's because it's always so bright now? Or perhaps they've changed how battery usage is measured. Not much I can do about it. Just an a interesting observation.
I have a Samsung Galaxy Tab S3 and it's great but I can't figure one thing out. Which is the screens contrast. Dark scenes in Netflix or VLC player are too dark and hard to see. I tried different brightness settings, with/without blue light filter and the other color correction option for cinematic mode but nothing really works properly.
Is this an issue with the tablet or is there another setting to change the contrast or something?

I also noticed this with Netflix. Was hoping that turning up the brightness would help but it doesn't.
YES, YES, YES, I am shocked this isn't widely reported, I couldn't find almost anything about it and I've been searching for quite a while.
First of all it is really crazy that popular apps like plex or netflix don't offer any capability to change the brightness of the video played. No, we don't change the colorspace, black levels, bla bla bla.
I DID find eventually a solution (the ONLY one that works, a bit clumsy as it is): http://phandroid.com/2016/03/22/twilight-app-reduces-dark-contrast-on-samsung-galaxy-s7/ (yes, it's for the S7 and yes I did notice there the same issue, which makes it even crazier that it isn't something widely known and fixed).
I just picked up an S3 last night and I'm having this same issue. I watched the opening scene of The Defenders on Netflix, and I could hardly tell what was going on. Rewatched it on a proper display, and you're clearly upposed to tell it's Danny Randy much earlier in the scene, but I had no idea in the S3 until a blue light was clearly shining on him from above.
I used Twilight on my Nexus 7 because it lacked a night vision mode, ala blue light filter on the S3. I'm not sure how that can really help. Surely other people have found more elegant solutions to this problem? I've opened up other media files and they're all simply too dark. I get it's an HDR screen, but surely it has a mode for non-HDR content!
Do oled display have a blue light problem, I though it was only really a led thing.
John.
Might be an inconsistency with the displays. I have no problem with mine. Not getting any lag either but running a heavy debloated rom also. Battery life could be better. It's stupid you can't turn off the Wacom digitizer when s pen not in use. On my note 4 when I lost my s pen battery life was terrible because the Wacom digitizer stayed on. Should be an option in settings to turn it off. If anyone knows how please let me know. I don't use the s pen very often.

Try switching from "adaptive display" to "oled cinema".

Switching to modes other than Adaptive Display just gives me seemingly the same shade of yellow....
I have tab s2 and you can't change adaptive display. I wouldn't have bought this tablet if I'd known about this issue. Very annoyed.
I actually have the issue on my Samsung Tab S2, that the colors are really "hard" and lots of color information are missing in the video, details are lost in dark areas. Is there some fix for this or is the screen just too bad on the Tab S2? I know the Tab S3 has a HDR screen, and the S2 not. I dont have any HDR screens actually, but I can put color range to "full" on my desktop PC, which will en-light colors a bit, making details more pop out in dark areas (though black isnt fully black anymore if so).
Any color profile other than basic is mostly unusable, too much saturation. Still dark areas lack lots of information. Is there no way to fix this? I tested this actually
https://phandroid.s3.amazonaws.com/wp-content/uploads/2016/03/Screenshot_20160321-154452-400x711.png
and it helps with the details in dark areas, but it also makes the black bars of movies in Netflix and video players not black anymore but gray.
So from what i can tell, it's only a stock rom problem. As the screen looks amazing running liniage (best screen in the house). But I've recently decided to go back to stock debloated, as I think its running a bit snappier than liniage 16 or 17.
Has anyone found a black level fix for stock yet? (preferably not a screen tint app)

:cyclops: It's beyond what you're suggesting which is known :cyclops: but thanks for it
EDIT: I have now found a full workaround. First you need to enable Blue Light Filter. Then go to Settings > Accessibility > Visibility enhancements > Color adjustment > Personalized color, and choose all the colors in the correct order. If you do it correctly there won't be any change to the colors and Blue Light Filter will be "on", but actually not, which will override whatever Android is doing that's making the dark parts of movies way darker than they should be. So far I haven't found any cons of this workaround.
Original post:
Sorry to resurrect an old thread, but after trying to fix this problem for like half a day (lol) I think I found the best workaround so far. If you turn on Blue Light Filter and set its opacity to minimum, the filter will be barely noticable, but the brightness issue will be fixed.
One thing I noticed is that not all apps have this problem. For example VLC, Youtube do have it (you can even see the transition of colors and brightness for a second when exiting to desktop view). However Youtube Vanced doesn't have this issue, so I asssume the operating system does this dumb change of colors when it sees certain parameters in an app (maybe something in the manifest.json file?). It would be awesome if some more knowledgeable people could look into this issue, maybe they could find something about why YT Vanced has normal colors.
