[Q] auto adjust LCD - AT&T Samsung Galaxy S II SGH-I777

I know this is a power saving feature but disabling it does it improve any image quality or no?

Yes, what that feature does is that it adjust the brightness depending on the color currently displayed on the screen. With that feature on everything looks dark, and dim. Turn the feature off and watch everything look bright and vibrant, and for more "oomph" change the screen mode to "dynamic". Gorgeous colors.

I wonder how much effect it has on the battery I get more than enough battery out of 1 day of use so I figure why not enhance the phone

[Q] Can the brightness be lowered even further? (CM7)

Hey,
I'm running on CM7. Can the brightness on the phone be set lower than the slider-bar allows? I'm often inside dark rooms and would prefer the brightness to be at a lower level. I know the phone can be less bright, because when you turn Desk Clock mode on (from within the Clock App) it set the screen to a super-low brightness. I was wondering if I can have that brightness for normal use.
Thanks.
settings > cm settings > display > automatic backlight > use custom / edit other levels
not sure what settings would accomplish this, or if it is even possible - but those are the settings you are looking for.
I have -no- idea what the settings do, or how to enable it at all. I tried setting everything to the lowest it goes to (2) but it did nothing... Hmm.
Look for "screen filter" app in the market.

Won't this just set a "filter" on top of the screen, making it darker? It won't really affect the actual backlight, will it? I was hoping to both make the screen darker, and save a bit of battery. Don't know how screen work, just what I think is happening.
According to the description and some users it saves battery on amoled screens...but I haven't tested it...you could be right.

I believe the effect in the desk clock is essentially the same as Screen Filter. It just darkens it. Just like Desk Clock on the Captivate, evident because the status bar stays the same brightness but the clock lowers. That's why the CM7 app makes the status bar disappear, so the app can darken itself and you won't notice it's darker because it doesn't affect the system and the status bar would have stayed the same brightness. Screen filter is a wonderful option. I had it to "hold menu button" in CM7 settings.

I don't think AMOLED screens have a backlight, that's why they're LED and not LCD.
I have the same problem: at night, the screen is too bright. Cyanogen has an option to only display one of the 3 primary colors, so you can turn on only the red subpixels. Sure, you are left with a monochrome screen, but it is dim and uses less power.

[Q] Screen Dims when all WHITE

Thinking of getting the GS2 or GS2 Skyrocket, but when I went to an AT&T store I observed tbat when you bring up the browser and go to google and then click the menu, the white area gets brighter, when you dismiss the menu, the white area gets dim (Almost seems like a lack of power issue)
It was very pronounced.
I did disable auto-brightness in settings
I did set brightness to full in browser settings also.
Is this a fluke or just a side effect of AMOLED screens
I tried this on 2 units they had running at the store.
There's auto brightness, but there's also the Analyze screen and adjust to save power. Did you get both?
Wow, I did not know about that setting and it may be cause of the effect I saw.
Thanks

Second Screen dimming

Just got the V10 and the second screen dims after 2 or 3 seconds after turning off the main screen. Is there a way to adjust the timing when the second screen dims? The dimmed second screen is almost unreadable because it is so dim.
Ditto, the idea that this is a replacement for a notification LED is really damaged by the dimming. (It's not just me that bought the phone based on that idea, right?) What I've found so far:
With the screen brightness set to 0, the second screen dims fully a few seconds after sleeping. Icons become about as noticeable as dust reflections.
With the screen brightness set to 100, the second screen follows the ambient light sensor after sleeping. Under bright light it turns itself up to the point where it's useable.
I've been playing with all the LEDs that Light Flow sees, but at least without root, nothing has any effect. I might look through the /sys files later. We probably need to get root first to figure this out.
On auto brightness it seems to be that the device adjusts the dimmed display for the ambient lighting? It's not the easiest thing in the world to see, but it's certainly not hard for me to see what notifications I have. I really prefer this over a colored LED.
Light Flow settings
For what it's worth, here's my current setup, now that the T-Mobile H901 is rooted. This does no one without root any good, and I don't know how it would translate to similar LED managers. I've been using Light Flow since the Sapphire (MyTouch 3G).
Light Flow device settings: check direct mode, root mode, and run every command as root. The Nexus 5 force reset option is checked by default and I don't know if that's relevant (no calls yet). Everything else in the menu is unchecked.
Let Light Flow control lcd-backlight-ex.
In a notification, set that "LED" to Solid and to 255 brightness. Check Enable Mixer and App controlled flash. With that last setting, the app will reset the brightness every few seconds even if the system dimmed it due to an ambient light change.
Now I need to edit some notification icons to be big and colorful. I wonder how this will impact battery life? Now the app is going to be awake all the time.
I've noticed that today on auto brightness the second screen will increase in light but not much. It also is not as smoth of a transition as on main display. It kinda jumps up real quick..
Yes for me I've noticed on Auto brightness the second screen will dim in a dark room and if you turn off your phone while in that room then come out... The second screen is still dim.... It's like th second screen doesn't respond to the light sensors at all unless the main screen is on.

It would have been nice if lg included the capability to change the second screen settings such a brightness or text color.

Another one of many things that it would be cool to see baked into a custom stock rom. Good stuff. I wonder if Cloudyfa might come over and cook on this awhile. I have always loved his stock Roms....

Color would be cool. A classic CRT bright/lime green, for instance, would probably show up much better than the white.
We need to get on their forums with these ideas. Maybe some will get squeezed into an update
An app which turns off auto dim in case screen is off would be pretty much help. Maybe I'll develop one.

Minimum brightness

You don't want to give your significant other yet another reason to yell at you while you're reading XDA in bed. Rate this thread to express what you think of the Samsung Galaxy S7 Edge's display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.
Then, drop a comment if you have anything to add!
I don't have on auto brightness or any power saving features on yet my display brightness seems to have a mind of its own. I can be in a dimly lit room and have to put my brightness slider past the halfway mark just to get decent brightness and the always on display will be so dim it's barely visible. Other times I could be in a well lit store or outside and the display will be very bright even with the slider nearly all the way down. It also seems the always on display may get brighter the longer it's on but it starts out very dim even if my brightness is cranked up. I really don't know what to make of it. Sometimes the display brightness seems way worst then my nexus 6p (not saying 6p has bad brightness just using as a reference cause most reviewers claim the brightness on note5/s7 is a bit brighter.) Other times the quality seems better then my friend's note 5.
Adaptive brightness? Sure sounds like it.
I am disappointed it does not go low enough like all android phones tablets etc. I read books in the Kindle app in bed and my iPhone or I pad can go very low brightness but all the android gadgets I have cannot they are always too bright and annoy her. I thought this could be the one but I guess not

Install LUX Auto brightness app and it should solve your problem, in fact you can set it so dim that you can hardly read it.
I find the always on display to bright. Is there a way to dim it a bit?

I totally agree with that, when you cover the sensor the brightness is way better.
It should be part of the environment, now it's more like "HEY LOOK AT THE TIME" kinda distracting

Yeah haha. The funny thing is that the "night clock" is perfectly dimmed. Wished that there was a setting for the AOD (always on display) to have manual brightness controll. And of course app notifications. Which the edge display can show, but the AOD can not. Strange decision of our Sammy friends.

Exactly, that would be perfect, I tried using AOD at work today and it's so distracting that it's actually worthless now. I also tried the night clock at work and it looks great, it doesn't bother me at all and it's very handy. Hope samsung will update AOD because it can be very useful.
But in my opinion the overall (auto) brightness is too bright, when I dim my screen it automatically brighten the display up to what it thinks it is the right brightness compared to the environment . With my previous phone (LG G2) it changed the auto brightness to the user preference.
You can fix this issue, set brightness 100% and reboot.
Hi guys, I noticed right now that if I switch from an high luminosity environment to a very dark one, automatic brightness remains the same and I have to uncheck and check again the "auto" option on notification bar. Other times, in same conditions, it adapt the brightness after some times instead of immediately. Dose have my phone problems?

This is to prevent the display continue changing brightness, it does change but it has a delay so your screen isn't flickering bright, dark, bright, dark.

This has been fixed with the update that came out this week #yay! It's now changing automatically, not as distracting anymore :highfive:
I noted that when I turn on the screen I a low light environment, it has a fade before the screen completely turn on, like a fade effect. I did some tries and this happen only in low light condition. Is this normal?

Yes, but if I put the phone orizonthal (for instance I put I on the table) the brightness change immediately. Why is that?

Do you have MM or Nougat? I noticed the same in MM but it works significantly better in Nougat.
The problems some of you have ... seriously? ?

Dark scenes difficult too see in movies

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.

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.
