I think my super amoled screen is dying:(

Ok when I first bout my phone about 6 months ago or less...my screen was very bright. Now I am starting to notice vertical dark lines across my screen, and the screen is noticiby allot less brighter than before...my 2nd gen itouch has a brighter screen that will blind u compared to my phone. Ive been running on overstock kernel eversince it came out so it is not the kernel.. I think my screens pixels r dieng also the dark lines r not noticable unless u got one big bright plain background but this is bad quality control

With the amount of galaxy s phones produced I think this has been darn good quality control. And i bet your itouch doesnt produce the great blacks that our vibrants have. If you have only had it for 6 months then you still have 6 months warranty left so send it in and get it fixed.

..super amoled so spd

Sorry but as fantastic as Super Amoled looks initially, it quickly fizzles out, and is prone to burn in.
check this thread out
http://forum.xda-developers.com/showthread.php?t=799750

SuperAMOLED doesn't have burn-in, but rather serious image retention.. so if you leave a screen on it will leave a retained image but you can get rid of it by playing back lots of video or full screen games.
I haven't had any problems with my Super AMOLED display or my Vibrant in general besides the GPS antenna thing which in my account is a flaw of design and not poor quality control.

problem with my screen?

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.

[Q] Blobs on screen that only show when screen is dark?

Hi All,
I think I may have to return my Nexus under warranty, I am delighted with it as a tablet but have noticed I am getting blobs appear whenever the background is dark and especially on black backgrounds, I have taken a photo of them with the tablet turned off.

I thought only amoled screens did this

It's probably the oleophobic coating coming off.

I will post a photo to show you what I mean as soon as I am permitted to.
I am surprised many people ever get past 10 posts on this forum having to type the image verification code every time and having to wait 5 minutes between posts and not allowed to post images or links!

Anyone got any ideas now photo is up?

Maybe from your case? My case gets little dust marks on my screen.

No, not dust, I have circled the 4 blobs in orange.

Like I said before, it looks like the oleophobic coating coming off. It's really strange that it would be coming off on a pattern like that... Is there a part of the case that has those 4 dots that could be rubbing on it?

I have something similar with my screen. It looks like a smudge fingerprint on the left side of the screen. I can wipe it off but it always comes back. I've tried soap, lens paper, water but it keeps reappearing after a few hours.

Checked and definitely no pattern like that on the case + when its closed it doesn't touch the screen anyway.

Just thought I would update on this, the problem didn't really get any worse but also didn't resolve so I have recently sent it back to Asus as it was nearing end of warranty period and they have put a brand new screen on now so a good outcome.

[Q] Is Banding Like This Normal for a Nexus 7?

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

S4 display

im wondering if the display will have pixels on the bottom of the icons like the s3 has,visible single pixels,,that is kind of annoying..i dont like iphones,but the display seems to be more sharp,do you think s4 will be sharp?? no visible pixels?

the 441pixel per inch answers your question

yes,i think its very nice,rich colors,vivid.

Remember, the GS4 has RGB Mode, which makes white's much more natural.

Cant wait til my upgrade!

tx for the answers .

It's so realistic! :cyclops:

It's gonna be an awesome display in every way. People who complain about PenTile don't have any reason to because the ultra high PPI cancels out everything. And if you don't like the default saturated colors, there's always Adobe RGB mode which is apparently better calibrated than HTC One.

Yeah you can still see them but you have to look a lot more closely, you wont notice it at a normal viewing position.

Don't quote me on this, but I recently read an article about calibrating the screen on the Note II. It described activating the Adobe RGB setting for realistic colors, etc, but the article went on to say that carriers removed this menu selection. Do you believe carriers will do the same for the S4?
I could be talking out of my arse, but I just recall this article. I can't locate it.

I know that AT&T GS3 didn't have the same screen mode selections like the International version did. Can't speak for the rest of the carriers though.

Which is why I'm hoping At&t retains this for the S4.
