I've read a few posts on XDA which mentions the visible banding in gradients. I find it's visible quite often, in the settings menu, in photos, in apps, videos etc. If this is normal then I'm shocked it hasn't been mentioned in any of the reviews I've. I would only expect to see a screen of this poor quality in a cheap brand.

If my Nexus looked like that I would be unhappy.

I have similar banding but not as pronounced probably because my brightness level is lower. I haven't really heard of a N7 that doesn't have this problem to be honest.
Mine has it but I only notice it on dark blank screens and I'm not on dark blank screens very often or for very long.

Seems to be down to a poor quality screen. I guess they had to make sacrifices somewhere to keep the cost down. Thanks for the link toidimaet, I read through it and there currently isn't a fix for stock 4.2.1. I could ask somewhere there if they would mind making one but it sounds like the next official update might also include a fix (if you can call it that) so I might as well wait.
I have the same issue, the only rom which i haven't this problem was PA so that means it isn't a hardware problem? I can't find RadientFix for SmoothRom.
not a screen issue
the N7 has an IPS display panel, which renders colors, well, too accurately. for gradients you can use strong jpeg compression, which is normally not visible on standard screens. the perfect screen also has disadvantages - most mediocre images look awfully.
by the way, all of the wallpapers that are coming out of the box are useless in my opinion for the same reason

Standard, always.
Dynamic is too rich for me. Movie is, poor.
I actually prefer movie, apart from when I watch a movie, when I change to standard... Retarded right?

I use Dynamic. It's like a constant live HDR mode. This is the single reason why I return to stock each time I try a new CM7 nightly.
Movie. Switched to Standard for a day and got poor battery life so I put it back onto movie. Standard is a lot nicer picture though.
Dynamic!! The colours in dynamic mode make my eyes have orgasm. Yeah, I cry from happiness. PP
Dynamic has too much contrast, you will loose a lot of detail in shadows.
Standard, Dynamic offers too much saturation for my taste.
Dynamic ftw, specially if u have a screen protector on, they kinda level out one another
Standard for me....

Movie is best. The other two are harsh and over saturated.
I am using standard, never played around with it really.
Used Standard for now but will try movie to see how much difference there is in battery life.
Dynamic is plain folly to use unless you have a very bad eye sight already.

thanks for the reply. it is very obvious if you look at house's face and the background is full of random colour as well. I restored the tab and still hv the same problem
Sorry, but from the still shot I see nothing wrong as you describe it.
EDIT: When I increase the brightness on my screen and enlarge the picture, I see what you're probably talking about in the upper right side of the background. As far as a fix? IDK Maybe remembering the tab isn't a blu-Ray player hooked up to a 1080p TV?
Sorry but hopefully someone with a more discerning eye and better knowledge of what you need to do will notice this from my bump and be able to help you.
If you can read this it was sent using my GT-P7510.

I don't see anything like what you described ... did you check the image with your computer too? Does it still have the random colors?
I tried to view the pic on my phone and it shows that there is no problem... which means is defo the problem with the screen.. could be moisture bt I'm guna sd it bk... thanks guys
It would have been easier if you took an actual photo instead of a screenshot.
on my p7500 no such problem...
Random colours as a rainbow effect? That is the known issue with earlier Galaxy Tab 10.1 and most of the current crop. It's called an oil slick, moisture under the screen, etc. Can't remember what the name was but it's a problem with the glass touching the lcd and causing the effect. It's mostly viewed under high humidity or temperature such as going outside in the summer with your tab or if you put pressure on the back.
The Galaxy Tab 10.1 GT7500 4G, has no such problem I kind of make out some kind of film they might of put between the glass and the lcd. Not sure but what ever it is it seems to have corrected the issue. Also by the way the GT7500 has Gorilla Glass which is not used on the GT 7510.
Just wanted to point out that my GT-P7510 does have Gorilla Glass.

Only thing I see is low quality on the video, it's either been encoded using low settings or it's a small resolution and being upscaled on the 10inch screen so the quality looks a bit bad.
So, one of the big reasons that I waited for the S3 instead of upgrading to the Galaxy Note, was because of widespread reports of "crushed blacks" on the Note's display (see this thread).
Crushed blacks is where instead of seeing an even progression in brightness from absolute inky black to the next darkest series of grays, you'll see black and then a stark jump in brightness to the next darkest gray. This defect makes watching movies and other media with lots of dark scenes a problem because it's hard to ignore the high contrasty / blotchy areas.
I'd appreciate it if someone could verify that this is a non-issue on the S3 by using the test image I've attached below. Download it, and view it fullscreen in a dark room. An actual photo of your screen would be nice too. TIA.
EDIT: Thanks all! Glad this isn't a problem on the S3 (and hopefully it won't be on the Galaxy Note 2 either).

I come from a Galaxy Note, too. The problem doesn't exist on the S3.
First thing I did when I got my S3 was that I did the test like on the Note (opened the image in QuickPic with the setting "Force true color decoding on") and went into a pitch dark room. Breathed a sigh of relief.
Here is a good example of what the problem with the Note looked like

I'm happy to report that I had no issue on my screen. Looked great and no crushing at all. I also went ahead and did a dead pixel check and turned out to be 100% :good:

Hi!
I heard about vertical lines visible on G2 but on mine I have them visible not only sunlight but also indoor when I'm browsing web. Especially on one color surfaces (google results white, google play background&green bar at top).
Really I'm guessing it's digitizer (line every each 1mm).
It annoying me because the're pretty visible. It is common? Please check in your devices at full brightness.

Yep can see them in sunlight especially with polarized sun glasses. Normal.

I think that's normal. I can also see them when I go outside and the lines reflect with outside light.

Ok but I can see them not only in sunlight, but in typical using. And they're not doted. Maybe that's not digitizer lines?
I can see them on my D803 in any lighting just by tilting the screen a little. Not dotted. Make the screen look like old-school graphing paper from high school. Never bothered me, though.
The extremely high reflectivity of the screen annoys me more. It's basically a mirror under fluorescent lights.

Hi all,
I've had my 6p for almost two weeks and tomorrow is my last day to return it. They will not extend buyer's remorse to a replacement unit so before tomorrow I need to decide if the issue I have is specific to my unit (get a replacement) or related to the AMOLED panel used on this phone (cancel).
The issue is that colors seem not to converge correctly, just like old CRT screens would. This is most noticeable on high contrast borders such as black text on light backgrounds, which my brain interprets as embossed text rather than nice flat text. Below is a zoomed in example showing this issue, upper borders are reddish/darker and lower ones are greenish/bright.

Anyone else seeing this? my friend's S5 has a similar thing but way less noticeable and i could probably live with it, whereas my 6p is probably too much. Yes this is my first AMOLED.
Thoughts? thanks!
