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
I noticed this from the day I bought it but it was only happening while playing games so I just figured it was a quirk in the game. But last night it started happening while web browsing and going through menus. The screen's brightness will increase/decrease at seeming random.
Auto-brightness is off, I had the screen on the lowest setting with IPS+ off and set to performance mode. Is there something in the menus I may have checked that would cause this or is it a bug?
no it's not a bug. I think its called dynamic display quality. some sort of method they use to save battery even more so. its never a drastic change. it does this gradually. I always leave auto brightness off and brightness never more than 20%. I don't even notice mines doing it as much any more. try a reboot just to clear things out. a reboot every now and then is good for the device.
Is there any way to turn it off? Seems strange for it to still happen while plugged in. Only reason I want to turn it off is because I was browsing the web with the lights off and it kept going brighter to where it was hurting my eyes.
In CyanogenMod, I was a fan of the setting that allowed me to "prevent phone's auto brightness from going down".
I like auto brightness and appreciate its ability to save battery life when indoors vs. enabling me to see the phone if I go outside in a high light situation.
However, under florescent lights, or in a room with a definitive light source (single lamp in dark room)... the phone's sensor keeps jumping it between light levels where the screen brightness goes up and down.... up and down... It's a bit dizzying and makes the phone somewhat uncomfortable to use.
Anyone find an app or workaround to automatically achieve what I want... other than... disabling auto brightness when it starts, setting an appropriate brightness level, and then, trying to remember to re-enable later when I'm outside (and of course, have a hard time then seeing the phone )
?
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
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.
