Color banding on gradients?

[ashykat]

Well I was one of the lucky ones to get my order in right away and my Nexus 4 was delivered yesterday afternoon. It's been great so far, but I've been noticing some color banding on gradients across multiple pictures. It seems most noticeable when it's my wallpaper, and it's noticeable on all brightness settings.

Is anyone else seeing this?

Pics?

Here's one that's easy to capture. It's really anything with any sort of gradient that's doing this though.

Low quality picture OR if its a wallpaper it gets down sampled so as to not hinder performance as much.

Yeah I could understand that if it were only happening on certain pictures, but I'm using normal to high res pictures at the proper size and it's still happening in every picture.

Every picture is being used as a wallpaper right?

Correct, and they are pictures I've used with many different devices in the past without issue. Galaxy S3, One X, Note, etc.

It's happening with stock wallpapers as well, I've just noticed.

Here's one of the stock wallpapers exhibiting the same behavior. My old iPhone 4 didn't capture it very well but it's still noticeable.

Maybe something has changed with the way Android handles wallpapers.

It's also possible that those phones OEM customizations (Sense, Touchwiz, etc) changed it.

Goto gradcolor.com and create a gradient. If it looks great like it does on my phone then at least you know it's something going on with wallpapers. For what it's worth I don't see any banding at all including wallpapers. But most of mine are predominatly black.

Does this appear like this when you view it in your Gallery on your phone? If not I believe Kevin is right that it will be down sizing the quality for performance. E.g Would they run a 20mb picture when they can downsize it too 200kb?

Strangely enough, it looks okay on gradcolor.com (if I look extra hard I can still see it but I don't think it's cause for concern), but when I view the pictures in the gallery it has the banding again. Very strange...

This one does it pretty severely in both the gallery and moreso as wallpaper. Does anyone mind testing it out to see if they have similar results?

Heres a fullscreen shot from in the gallery on my Nexus 4 as well as when it is set to wallpaper... Looks pretty good to me, although I do see some minor banding when blown up..

I see the banding on the original when zoomed in too on my pc sure your not be mistaken?

You have to take a picture of your phone's screen, not a screen shot. Screen shots taken via software don't change if you have a defective screen.
