Some apps make screen B+W - OnePlus 6T Questions & Answers

I just noticed that some apps, when running in the FG, fade the screen to black and white. Whe these apps are put in the BG the screen fades back to color. Even more weirdly, if I take a screenshot of the screen while it is faded the B+W the image is in full color.
So far I have noticed AFWall+ and Adaway do this. Any idea what is going on? Did I accidentally turn on some obscure setting?

Probably because you added those apps to reading mode (settings - display - reading mode).

Small Request to whoever has the Note

Hey! Can someone with a note set a pre black background a the lock screen background and report whether it looks normal? Someone had reported a problem with the gallery background with a black image, but I couldn't find a mention of lock screen there. Just google image search "black" and download and set it as lock screen. Seems to be giving me pinkish hues... same image works fine as a desktop background...

Most lockscreen wallpapers look horrible on my Note, not sure if my 240dpi is causing this. I use another lockscreen app set to transparent, so I don't care.
The Note's screen is 24 bit, so a picture with 16 or 8 bit depth might not be rendered properly.
Best to find a 24 bit image to test, try Google search.

Same here.
Good to know that I'm not alone. Every other background seems fine. Same thing happens with the gallery background when the only image in the folder is a pitch black one, right?

Well all those images render fine in other applications on the phone so its the lockscreen wallpaper 'setter' wich messes it up I think.
Ya, I'm pretty sure too that that is the case...
I have a black lockscreen and it looks great.
I have noticed that when I have 'screen filter' app running, it dims the foreground but causes the background to do the 'grey' thing.
I have most of the auto display stuff turned off (auto brightness, auto adjust screen power)

That guy mentions that his blacks aren't completely black. Our problem here is that setting a completely black image as the lockscreen leads to a messed pattern with greyish/pinkish stripes...
edit ; same thing occurs on mine. I even created two black background non compressed, 24 bit, one even with 285 dpi.. both show the wierd little gray stripes on lock screen. only notice it in very dim light by the way and even then if i look very close.
this is what i use. both screens look black as night.

Use the darker red "sun" wallpaper gallery image - awesome on mine!
I have the same problem...
Has anyone tried restoring?
I set a black image and got the very dark grey bars others have described. However, I reset it to the original wallpaper and noticed that the white-ish parts of my background has bars as well! Just not as noticeable, and its only on the lock screen.
This is my background picture by the way:
http://interfacelift.com/wallpaper/details/2754/yellow_autumn.html
There seems to be some kind of gradient over the image on the lock screen - I'm just using the default for now, but if you set the default as your normal background as well as lock background, there's quite a difference. Could it be this gradient which is causing the issue with pure black backgrounds?
I'm using widget locker and here is my lockscreen with the homescreen wall paper which uses solid black background color
I am having the same issue. I just noticed it yesterday. I really thought it had something to do with the phone going below the minimum brightness it was designed for, but if you look at the notification bar it's still a clean black.
My guess is the phone is compressing the lockscreen wallpaper to save memory.

Can people try WL (If you've purchased it) and see if it does the job?

Screen colour problem, please help

I was looking at Google Map when I noticed the colours changing. It was as if the contrast was suddenly being reduced making the colours look washed out. When I went to my Home screen my windmill live wallpaper is also looking washed out because the grass no longer looks very green. Has anyone else experienced this problem?
I attach some screen captured to show what it looks like.

Go to settings>display>screen mode you have changed the color management. And see if you have enabled auto adjust screen power. Maybe on of those are responsible.

Do you use Custom Power saving?
Could be your battery running out, so its reducing your display to save power.

I'm not using power management and I have the phone on charge.
I've discovered why there's a difference in my Google Maps screens. It seems that sometimes the map is overlaid with a white circle which makes it look washed out. I attach a screen shot so you can see what it looks like. I think the circle is highlighting an area around my satnv location.
But I'm still not happy with my windmill which still looks washed out.

wow man there is a huge difference.... no way my gnote is not doing this for sure... try to upgrade to 2.3.6 and see if that fixes it
you're sure it's not a 'feature' of the windmill LIVE wallpaper?
On the second image you have good weather, the sun is shining. On the first image however, it seems as if you have bad weather, no sun, only clouds, thus the gray layer.
So maybe it's nothing the Note is responsible for, but the weather dependend Live Wallpaper.
I know is not the same problem but maybe related,my device have some brightness change in the display,many times i'm reading and see the screen do some dimming the screen lower down the brightness and go back after like 30 seconds to the normal bright,I have enable the Auto screen power but i try desable and the result are the same.

I think you are probably right for nothing has changed except the weather.

[Q] Screen changes hue automatically? How can I turn it off?

Okay, so as the title says, the screen on my VZW GS4 seems to be changing the hue depending on what colors are being shown on different parts of the screen. For example, when I get a text and the little green icon pops up in my notification bar, the whites on the screen darken, and as soon as the icon is gone, they go back to normal.
The same thing happens in the youtube app. When playing full screen videos colors get lighter (and more unrealistic) and then when I click on the screen and the pause button and other menu buttons shows up, the colors darken and become more realistic.
I've turned Adapt Display off and this happens whether it in Dynamic, Standard, or any other of the display modes. This strange behavior is very familiar when the phone is set to the lowest brightness.
Anyone know why this might be happening or know a possible solution?

Just tried that and it still seems to be doing it. It'd quite annoying especially when in apps with dark backgrounds or night themes. Anyone have any other suggestions?

[Q] Screen Mode: Standard VS Professional Photo?

I've been trying out Professional Photo mode for awhile now but it just seems yellow-ish.
Standard seems to be okay.
Does anyone else have similar issues?
I was told that Professional Photo mode is more color-accurate

That mode has a larger colour space meant for certain professional photo apps. For movies, and everyday normal life use Movie mode. If you like exaggerated colours go for one of the other options.

Adapt Display Yes.
Auto-brightness No.
I use a Black Background on my Homescreen with White Text (DashClock) and it looks yellowish in either Pro Photo Mode or Movie Mode
I have tried professional photo as well, but somehow went back to standard mode. But for reading books, professional mode is nice as the screen looks warmer.

Weird, I use Ocean HD (beautiful live wallpaper) mostly since I got mine on a charger 90% of the time and discharge it fully every 2-4 weeks. Maybe I forgot to mention a setting or it is a defect of some kind (software or hardware).
Worst case you could reset your phone to default and immediately set it to Movie mode to see if your clean phone already has these problems. Hope you get this resolved soon, and by simple means.

maybe it is something wrong with my eyes. Standard is definitely more blue whereas Pro Photo and Movie are more warm in color.
there's a switch when I reboot my phone from Blue hue to warm.

Yes, after a reboot it starts at a default screen mode setting and after a couple of seconds it checks your settings and then changes it. I noticed this an hour or so ago on my Note 3.

The default is Adapt Display, which on your homescreen exaggerates colours, so my blue underwater Ocean HD screen looks even more blue. It switches to 'normal' blue.
I just checked some more settings, but are you by any chance using Power saving mode or any of those other fancy settings? Having owned 7 Samsung Galaxy devices by now I always immediately make a round through all settings and switch off everything that is useless (to me). I hate stuff like auto-brightness, which may be great in a car if you use the phone hands free.

hmm I use power savings mode but only Limit CPU and Disable Haptic Feedback. I unchecked Auto Adjust Screen Tone too (it supposedly saves power)
Do you use Lux to adjust brightness?
hmm. mine is a black background with just DashClock in White Text. it gets a little yellowish.
In Standard. it is like mint white.

I would disable Power savings etc. for now to see if it helps. I remember some option with "Lux" in it, but really I just disabled Auto-brightness and adjust the brightness level in the notification panel.

I gave it a try before but it still looks kinda warm/yellow. it is not like there is a yellow tint/screen but the screen just looks warmer.
I've actually never seen an Amoled with Perfect white color.. always a bit to the warm side..
I tried both Movie and professional mode, don't like them at all more yellowish/greenish on the white
especially when comparing it to an IPS LCD screen... then the NOTE 3 is very warm and a tiny bit greenish on white (standard mode) only really visible when side by side with example LG G2...
But then on the LG G2 skin tones looks a bit pale, and with to blueish/cold
so it comes down to what you prefer
I'm a bit torn between them... but when it comes down to choosing I think i prefer the Note 3 screen...
Remember NOTHING IS PERFECT

[Question] graphical glitch? galaxy s5 verizon 900v

Hi- this screen never appeared before and now it does -.- tried wiping factory resetting and this image wont go away from my homescreen. Idk what happened please help looked everywhere of how to remove this but no one has had this issue. This never appeared on stock until after i unlocked my bootloader and installed cm. Tried to use the repair assistant and its still there.
edit: idk why it does not show in my screenshots. here are some photos taken from my iphone... hard to show but there is a white line that is in the background of my homescreen. Shows an sms icon slightly transparent. Annoying **** to look at when I take pics on snapchat. As you can in google playstore and the snapchat photo a SMS icon appears behind the mic in play store and under the switch to facecam icon in snapchat. Does anyone know a fix??
I still have no idea what you are talking about.

lol. ok before on my screen it will be normal fine no graphical errors no visual glitches. pictures wont show it for some reason but if you had my phone in my hand it would show up as SMS icon at the top of my screen like right below the navi bar. Shows up in camera and on my snapchat. Never happened till now. Idk if my screen got messed up or if its the constant switching of roms etc that gave me that glitch. its like a white line that separates the navibar and the rest of the screen at the bottom shows a menu bar on the left corner and some icons. its very transparent under the homescreen display like if the stock rom overlapped
like it shows a small phone screen is under the home screen. in the background- get me?
It's screen burn in. It happens with amoled screens if they are left on a static image too long. You can try some burn in fix tools in the play store. That's why you don't see it in your screen shots it's a hardware problem.
