I have it too on i9500.. Ive been wondering why no one reported this.

It's software. I have read the I9500/I9505 aren't the only phones it happens on.

happens to mine too, im from tmobile forums. Def a software issue

Not only that but the hue of the screen changes too.
It's very subtle and most people probably won't recognise it but the screen goes from having a magenta cast to a green cast and back again when keyboard is toggled.
I only noticed this when I was watching a black and white you tube clip, I touched the screen to bring up the pause button and as the menu came up the screen changed hue then when I clicked it again and the menu went the screen hue changed back.
Very weird!

agree..

I noticed the same thing after a couple of days. Really annoying and I'm hoping for a quick fix!

Distorted screen in web-browser

I'm running nightly 28 on an HTC Legend. I have a problem in the web-browser. Sometimes, when the browser is displaying the address bar, the screen is "shifted" down some pixels. What goes below the bottom of the screen re-appears at the top. See the two attached pictures.
Anyone else experiencing this? When the address-bar disappears, the screen goes back to normal.
This is quite an ambiguous issue...
How regularly does this happen?
It happens every time I open a new page from the bookmarks-menu as long as I use full-screen-browsing.
When I use "non full-screen" there is no problem.
I guess the browser gets confused about the placement of the address-bar if the status-bar of the OS is gone..
Anyone else experience this in full-screen mode in the browser?
I have before, but it's wasn't exclusive to the stock browser. I used to get it with Opera Mini and Dolphin HD.
I'm genuinely stumped. Sorry.

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)

Looks like the same problem as with the video playback:

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.

So no lock screen issue with your phone?

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?

System colors output fails

Well, I suppose I'm not the first, but still I hope this is fixed. There are parts of system especially menus and gradients which are rendered terribly. This is a software bug, since everywhere else, colours are rendered fine. I have screenshots attached. Is there a fix for this? Thanks

You are really complaining about the color of icons on system menus?

no, if you look closely at the grey background on system menus you will notice it isnt a flat or evenly graded colour, down the middle is a line, the best way i can think of to describe it is its like an oil spot on a dark shirt, its not always noticeable but its there.
Exactly, thanks!

Seconded! And I was beginnig to think there was something wrong with my device. Yesterday I noticed a slight discoloration when looking closely at the popu menu backgrounds (like the one when you attempt to install a downloaded apk file). It appears in the right part of the box. It looks a bit like a hand, a splash of liquid but with sharp edges. When I rotate the screen horizontally the shape keeps being rendered in the same part of the menu and retains its shape. Curiously enough when I examined menus in other parts of the OS the pattern was different, more blockish. I think it will be hard to photograph so check your tablets guys. The screen on my device is otherwise fine so it must be software related.
I don't recognize what menu you are on, but on mine settings/apps shows no background blur like that. Manual lighting, 50 percent.

It's export menu in dropbox. In that link, it was shot in I think, notification ringtone menu.
Good to see Google is fixing it.

No fair blaming Google for an app problem. There are a million ways Dropbox could have messed that up.
Can you give me an instance that only involves Google apps? Like maybe in Google drive?

Any system dialog box. Go to settings and set a "notification tone" in the dialog box where you select the sound you can see horrible artifacts that look like dark gray mountains
That and set any gray gradient as a wallpaper and you'll see horrible banding

OK... I went to Settings / Sound / Default Notification.
Then it gives me a choice of apps to use to browse to a sound. I chose Media Storage (the only Google one).
Now I have a list of tones and checkboxes, with a gray background. Brightness manual, 50%.
Holding the screen straight on, and tilting to look straight across I see no gradient or artifacts at any angle. Amazing off-axis range...
Anything else I can try, or is my device just "different"?
I have those gradients too, funny its not reproducible on all devices

Could be. You on a custom ROM? or Stock 4.2 / 4.2.1 ?

Stock 4.2.
Not currently rooted - root makes multi-user unusable for me. Root Manager has it "temporarily unrooted".
I don't have a gradient background to try. That notifications panel is an even gray. No gradient.
Bump up the brightness to 100% you will surely see it if it is there. I just updated to 4.2.1 and it is still here. This update in fact broke my Android Beam, I can no longer send images from my Nexus S to Nexus 7 like I could on 4.2

bug or something i9505 noticed on f8 and before fw

So to make it short. When you install any app with black icon like offitial 9gag app from market try to scroll left and right in app drawer and yo will see black trail behind icon. It also happens in some apps with blaxk background and in galery with zoom in and out. I wonder is it amoled issue or just software. Just try it for your self. And if sombody is on aosp try it too so we know if you have it too.
It's called smearing and it caused by the fact that the pixels are simply turned off when the display need to show black color.
The screen isn't quick enough to "wake" the black pixels so it looks like smearing on the display.
Google ROM doesn't have it, because Google replaced the black with grey, so dark that it almost looks like black. If you set your brightness to full though in a dark room you'll see it's grey. This way your pixels will never be turned off
Me Gusta!
Does it have to do with refresh rate?

[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.
