I thought my screen was great, even after seeing this thread on Android Central. Received a new one today and the banding is highly visible and shocking.

If you put up a solid white wallpaper it's very visible and remains visible on virtually all plain colors applied. The text of my last post follows:
["You are all 100% right about the dark bands. After a bit of testing, I realized which launcher you use will also affect the depth of the color of the top and bottom banding. With TouchWiz the top is dark, though not as dark as Apex, and the bottom is somewhat lighter. The same applies to Nova for the top and bottom banding. On Apex the banding is very dark and really bad.
The Kindles suffer from a similar issue and it has to do with the leds. Amazon got a lot of grief over their Voyage because the color differences and banding are so bad. Not everyone could see it though, which leads me to believe it also might have to do with vision differences. I always use very dark walls and so didn't notice it on my 8.0 until my 9.7 comparison tab arrived today. The banding was so bad it shocked me. I LOVE my 8.0, but I may return both and wait for a later iteration, and / or see if anything is fixed with an update. I intend to root ultimately, so I'm not liking the idea of taking any updates.
Has anyone tried using their tabs in natural light to see if the issue persists? I can't today or tomorrow. Will try it on Friday.
FWIW - this issue is visible on any plain color screen with vary degrees of visibility."]

Have you noticed that the lock screen wallpaper - default from Samsung - doesn't have the issue?

I was just wondering if a white background would consume more power than a black background for the theme settings.. Anyone have any thoughts on this?

Depends on what phone you are using. The samsung and dell with their samoled screen consume more power with a white background. The htc phones are using s-lcd which means it doesn't matter if it is white or black. I prefer the white background on my HD7 it looks nicer.
Oh cool.. Im using a HD7.. Was using black in thinking that it will prolong battery life.. Now that you mention that, i'm switching to white =) Thanks =)
Black looks best.
I like black but it annoys me that the fonts on black look horrible. For instance, in settings, the small fonts distort when scrolling up and down. This doesn't occur on white. Nor does it occur on the Omnia 7 even when on black. So perhaps this is a HD7 issue, or perhaps it is just my HD7. Am interested to know if others have noticed it.
I hadn't noticed that. Now I'm bugged by it. Thanks.

Could you elaborate on this distorting text? I haven't noticed anything on my HD7 with black background. Text looks wonderful on this screen and Windows Phone 7.

just open the Settings page and scroll up and down slowly. Notice how the small subtext is a lot tougher to read while scrolling. That's what he is referring to I believe.
The text issue is called "ghosting" and is due to the low quality LCD panel on the HD7, which has a very low pixel response time.
It bugged me a lot on a black background. It's not noticeable on white.
Yep, as the other guys say. A better description than my original one is that the text has a "shimmer" when scrolling. It sort of fades out.
Rather than it being a panel issue, I think is might be a cleartype or font smoothing type of issue. Later on I'll do up a bitmap image with some text on it, and see if the problem occurs. If yes then it's a crap panel and if no then maybe fonts/cleartype/software and hope.
Another problem with the black background is you do see the backlight ever so slightly. Yes, I knew this, when I (now somewhat regretfully) chose it over the Omnia 7. Be good if Microsoft gave us more colour options, I'd probably use a very dark grey if available. My £99 ZTE Blade has far nicer blacks than my HD7 Sorry to rant. No need to flame. I think the HD7 will be the great WP7 hacker/modder device and this alone is enough for me.
I created a bitmap and emailed it to myself. The shimmering effect did occur when moving around. So it does seem like a screen or a screen driver problem, and nothing to do with fonts and the like.

Here's your answer. Enjoy whatever color you want.

I thought it was because grey on black has less contrast than grey on white. Could you do the same but instead of grey use white.
I have just again compared the scrolling of the settings page on my HD7 with my Trophy and there is a huge difference!!
On the Trophy's SLCD screen there is no ghosting and everything just flows and stays readable all the time.
Everything is just so much more vivid and vibrant on the Trophy !
It is indeed a shame that HTC have not used a SLCD screen for their flagship model
I've stayed with white I tried black for a bit but it did not look as contrasty as hoped.
Sorry tbk21, I can't try it as I sold the phone. Got loads of interest on Gumtree. HD7 is not the one for me. The speakers, the screen and the slow loading of sdcards. Sticking with my clunky Android for now. Maybe I'll be back for the second wave of WP7 phones.
So i have been trying to get a black background that is truly black.
everything i have tried has left a slight hue on the background. back 2 black is not supported or i would have tried that.
is there any way to get background to remain off completely and only light the pixels for the icons, clock, notification etc etc. i notice the info bar at the top is darker than my black background and no matter what i cant get the background to go completely black.
my reasoning is if i make the icons into line art, and keep as much of the screen off wherever i can i can stretch battery life even further. it worked wonders on my gs2. But having a slightly glowing background ruins all that.
I'm not sure whether it's supported, but you can try making a monochrome bitmap-file (.bmp) in MsPaint. At least you are sure this way that the black is truly black.
Have you tried using different launchers? Are you sure the hue is not just your icons giving some 'bleeding'?
thanks, i will give that a try.
its the same with go launcher and touchwiz. its actually magnified on the lockscreen showing lots of banding.
Try this pic. I use it on mine and looks black

My first Note did this so I sent it back. My new one does not do it.
still no luck, apps with black backgrounds look fine.
i tried an all black bitmap and that didnt work either.
is there any way to turn background off and just leave it blank? would that give me a pure black background?
like i said i dont think its a hardware problem since the app backgrounds look deep black unlike the wallpaper. i did see something about the note only being 16 bit and that was causing weird display issues due to scaling or something, blah blah.
its using 24bits
thats right, the note is 24 bit and the os operates in 16 bit currently, right? either way i need to find a way to fix it.
I used a plain black GIF. Works fine for the home screen background, but on lock screen it has barely noticeable dark gray lines in it until you touch it and the unlock symbol appears.
here is the one i made
this black is one color 24 bit png on my note it is completely black at any brightness. let me know if it works. 800 x 1280 black correct dpi blackground

or download "no wallpaper" from the market - simple app that just adds a wallpaper that is totally black. Works a treat.
Try an app called COLOURS by Tim Clark
Looking at the screen very closely, I can see what can sort of be described as screen dithering. This is most obvious with a solid colored background or an app with a solid colored background. Looking closely, you can see that all the pixels are not uniformly one colored.
I don't see this on my Galaxy S3.
Anyone else notice this?
Edit: To be more accurate, it seems like it's a screen hardware issue. There are faint horizontal, fuzzy, pixelated lines.
I've seen several threads talking about how prone the Note 9's AMOLED screen is to burn-in. I wish to use the default light theme for once as it complements my phone's new background and style. Since the day I updated to Android 9 I have used the dark theme and have some concerns about burn-in, especially in the navbar area. Has anybody here who has used light theme regularly noticed any form of burn-in?
Burn-in only happens if you have a bright picture displayed on your device's display constantly for a prolong period of time. However if you use a dark theme, it will preserve your battery.
Just a pet peeve of mine; the UI on Pixel 7 in dark mode isn't actually black, it's more like a grey or brown depending on what style you choose. Makes it look like an LCD not an OLED. I've attached 2 screenshots of app drawers to illustrate. One is from my Pixel 7 which isn't exactly black, and the other is of my Galaxy A53 which is pure black. Just looking to change that if possible.

I bought Nova Launcher Prime a couple years ago, may as well use it. But for what it's worth this option should come stock.

You are welcome to try this if you are stock-rooted. Flash in magisk app.
The drawback is that upon rebooting your phone, your phone relocks itself (not reboot). When you unlock it the second time, the mod takes affect. Without that post script, the phone would bootloop. This happens everytime you reboot your phone. Because of this, this mod is incompatible with the magisk module that is a "bootloop protector" as it sees this mod as bootlooping instead of relocking and disables the mod. This mod is using cool_modules installer from here:

I tweaked it to use with Pixel Launcher.
To get your settings background black, you go to settings/ display/display theme and choose stock-black.
Might be worth a shot.
Also repainter app has this feature.
The reason why the color of the dark theme is not black but something similar to gray is because when you move white text on a completely black background, an annoying color plot is perceived due to the delay that the screen pixels have. OLED to go from completely off to on, and it is precisely here where the grays fulfill a very important task, since they generate a contrast that "hides" the phenomenon described above.

So Google is using inferior OLED panels? I find my A53 has a much nicer screen & no issues with text in black background scrolling.
I mean, look at the fingerprint. I don't understand how this is a "Flagship" UI. My A53 is slower for sure, but the UI has nice blur effects, pure black backgrounds, the fingerprint isn't an icon; it's a pure white translucent fingerprint. I just expected better. I don't feel like rooting it and bending over backwards to get it to look decent. I put it up for sale and no one wants it. Will trade it in at Best buy for a discount on a Samsung. The pixel 7 takes great pictures, it's fast, but the battery life is mediocre and The UI is too bland for me; it's washed out.
