Hi,
I just upgraded my firmware from KBLH1 to XDLK1, used the official version from Samfirmware. Everything seems to be working fine except on the lockscreen I see weird grey smudges on the left side. It wasn't really clear with a colored wallpaper, however, with a black wallpaper its very evident. Attached is a screenshot of the same.
Not sure why this is happening, and its only happening with the lockscreen, I have a black wallpaper on my homescreen as well and it seems to be fine. Is anyone else facing this issue. If yes, do we have a solution for this.
Also, the LED looks a bit dimmer than usual.
For the screen effect:
-comes from the ripple effect
-was already there on ICS
-only solution is to turn off ripple effect in lockscreen setting
For the led thing:
-since JB, the led is set by the light sensor (same as the screen when set to "auto")

Hi, thanks for your reply. I figured out the ripple effect part, didn't know about the LED thing. Thanks for that.

i'm using tmobile SGS3
whenever i set my lockscreen picture to black-background image, the borders of the screen gets whitened out, almost upto the middle.
is this normal?
i only see them in lockscreen with wave-effect
Turn off ripple effect.
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.
Yesterday night I noticed that black pixels do not switch off completely on my phone. (as they should on AMOLED, right?)
Try it this way:
Set your screen brightness to almost a very low value.
Now look at a picture which has a black background and very little color in the middle etc. The room has to be dark, otherwise you wont see a difference. (You can also cover your had with a blanked etc., just wait a moment, so your eyes get used to the dark environment).
Hide the statusbar, navbar etc., so only your picture is shown (Tap on the picture once in Google Photos).
When you disable your lockscreen and switch the display on and off a few times you'll see that the picture vanishes first and than the display goes completely dark. It looks like a very light yellow back-light.
Another way:
Again in dark environment power off your phone. Switch it back on and watch the bootlogo. The surroundings (everything that's black) is truly black and "switched off" and than some secs before completing boot the "back-light" switches on.
I tried to find a solution for that. The only thing I found is a setting in Kernel Adiutor named "Minimum RGB value" under the screen section which is set to 35. However lowering it to 0 does not work, the value get reset to 35 every time (Higher value does not change anything either tho).
I'm running Oxygen OS 2.2.0 with bluespark kernel + root + xposed (Gravitybox + XInternalSD)
maybe the black is not that black?
edit: just tested with fullhd resolution black picture and red dot pixel in centre(PNG file, not jpg nor bmp) and everything is working as intended - black is pitchblack(same as when u just block/shutdown ur phone)
edit2: i'm not having my reflex by my side this couple of months, but you can check it making a photo in light isolated room with low shutter speed(20sec should be enough, if they really produce light)

Thank you for testing. I reproduced your result with a #000000 PNG and everything seems fine, as long as the brightness does not go below a certain value. Turning auto brightness off and sliding the brightness completely down enables some kind of light in the whole panel.
Could it be some android feature, which put's a light overlay over the the screen image to protect the eyes in low light environments, like these warm filter mods?
I love the look of Ambient Display mode so I have one question. Is there any way to make a locksreen look like when it's in Ambient mode? No wallpaper, only watch and black/white notifications. I want to have this look always when I wake up my OPX, not only when I get any notification.
Thank you for any suggestions :highfive:

Change wallpaper on lockscreen settings with a black one and you've done
Edit. Seems that we can't
Well if you have OOS you can change the lockscreen wallpaper in settings->display-> lockscreen wallpaper.
I also found a way to make everything black and white (notification I mean).
I like to play with TASKER and the quickest thing to do was:
Create a profile with kernel adiutor with the scale of greys that will be triggered by tasker when the screen goes off
then create a profile of kernel adiutor with normal colors and it's triggered when you unlock your phone.
The only problem is that take a second to get back all the colors on you screen when you unlock it but you can give it a try
Try using the AC Display lock screen, works really well. It's got an ambient display interface. You'll like it.

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.
