Quick question -
I have a rooted HTC DesireHD & sometimes I'd like to use the 'Auto brightness' feature - especially if moving indoors/outdoors quite regularly.
However I've noticed that the screen brightness seems a little 'too' bright compared to how I usually have it (indoors I usually have it ~12%, outdoors ~90%) - In 'auto mode' the 'indoors' seem to be about 20-25%
I pretty sure that there is a way to telling the Android system the level to have the screen depending on how much light the light sensor picks up - but I think that involves editing certain files & 'ADB' command etc (which I'm not totally confident I could do)
Does any1 know of an App (preferably free) that shows the current light level picked up by the phone & the brightness level that's been currently used, which also allows you to alter (& save) a lower value for that light level (perhaps with a slider or value box ??)
Thanks in advance
Well despite 130 views - seems like no-one has any suggestions
Anyway, I persevered with Google play search & it seems I may've found a couple possibilities (Avaliable as 'free' and 'paid for') so I thought I'll post them here in case any1 else wants them
There's Custom Auto Brightness (free) here
AND
Lux Auto Brightness here (Lux has paid version that allows even darker levels of screen display)
I've tried out 'Custom Auto Level' but either I was doing something wrong, but on occasions it would'nt dim the screen in bright light (I tested by shining a torch onto the sensor), however I'm currently trying out the LUX [Free] version to see if it'll do the job
(Took a while to actually figure out that you had to use the 'Link' option to actually SET the brightness of screen to Level of light detected )
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
Hello,
I'm just looking for some real user feedback on the display quality, specifically the color temperature / accuracy. Detailed reviews posted outline indicate that the "white point" performance of the G5 is relatively poor, resulting in noticeable blue tint for white backgrounds.
1) I understand that there is some amount of screen adjustment provided by through accessibility settings. Can anyone confirm if this helps to reduce any blue tintedness or if there are other mechanisms to do so?
2) Can anyone just provide feedback on the screen performance in this regard?
Thanks.
I have the unlocked RS988 model, and yes the display is a bit "cool" for my liking. I installed Bluelight Filter and was able to use one of the color filters (brown) set to 8% which has helped.
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)
Touch the left hand side of the screen when watching netlix and a brightness slider appears

: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.
Has someone experienced "dancing blacks" with vertical or horizontal scrolling, specially in low bright settings?.(40 or below)
I have purchased an EU ver. Of V30 and i experience this behaviour every time i do scrolling with photos, desktop icons with black contour (like netflix) webpages with black línes or blocks... Or everything containing black colour.
When i move the photo, scroll across website... The part that contains black colour seems to dance on screen, it's hard to describe but it's something like jelly effect, the black part of the object, photo... seems slower and doesn't scroll accordingly. I went to a local store to check it on another unit and discard a faulty one and i saw the same effect.

That's the feature of all oled displays, nothing you can do with it except changing the brightness to the level it doesn't show any signs of this "violet trails"
i have that behavior too on my H930DS. no solution yet.
The phone regulates it's brightness through PWM, so that you don't have the same issue like on the g flex where the whole display got blurry and grayish when you turned the brightness down. Because the display shuts itself on and off many times per second (222 times according to a German review page), you see that when you are sensitive. Just set the display brightness higher, then you should be fine.
