I've seen some of you have said there is some 'bleeding of light' what does that mean actually? Are there holes in the casing or is it something with the screen? And how bad is it?
Edited to add: Despite the troll, a few people here have reported this problem first hand - however it appears to be small, so hopefully they got a rotten apple.
Having replaced my own LCD backlight, I can speak to it.
Basically the LED lamp sits on the very bottom of the tablet illuminating the tablet from the back (hence backlit), the light is supposed to be contained but sometimes the lamp housing may contain gaps and light will leak through those gaps. They appear as light flares across the above layers.
If you google Ipad 2 light leaks and view Images, you can see a great deal of reports with sample images of the symptom.
I'm not quite sure why companies don't just employ a rubber gasket or flap around the lamp housing to get a good light seal.

There was a comment on one of the android forums.
I noticed it when I first switched on my device, but it was late at night in a very dark room, and brightness was on full. I have brightness set to auto now, and I have never noticed this again.
I am very intolerant of defects such as this, so if I am not seeing it, it's fair to say there isn't a problem. Of course that's just my opinion, but I really don't think it is an issue.
Hold on a moment .......OK, I've just gone and stood in a dark room, and brought up the Gallery App, because it has a dark border. No backlight bleed obvious until I turned the brightness up to maximum, at which point there was a vague semi-circle of backlight just to the right of the keyboard dock. Turning the brightness down to a sensible level solved the problem.
Hope this reassures you. I should perhaps point out that I have no affiliation with Asus, or Google, and no vested interested in device sales.

It's pretty rare I think. I've only read it on a couple of occasions and as far as I know it's the only physical issue with the tablet. Everyone keeps raving about it's build quality. So, if there is any light leak in mine (when I eventually get it) I'm swapping it. Just another reason to try it in the store

The very first thread here, where people were asking for this forum to be made, there were a few people who said theirs had bleed (and a few others said the sound was uneven in playback, one side very loud the other low)
I haven't seen much, so perhaps its only a few unlucky people.

No, spare me your rolleyes crap. It was people saying: My device has this problem. And some saying I'm returning it.
I've been reading a ton of sites about this device, and may have gotten confused about which site i read it on, but clearly there is no mistake when people say they have the problem, so don't accuse people of lying.
It certainly is mentioned here http://android.modaco.com/content/asus-eee-pad-transformer-transformer-modaco-com/336683/eee-pad-transformers-owners-thread-14-04-2011-first-post-updated/
"I had started to noticed light on my screen that shouldn't be there. This obviously is a backlight bleeding problem. ... the manager then took a look in the dark and he noticed it and said it was a fault with the screen and I can get a replacement."
http://www.avforums.com/forums/14430336-post46.html
"Screen. Some light bleed unfortunately (this is also being reported by other users on XDA forums/Modaco etc) - not a deal breaker, but it is there.. admittedly only noticable when using at night... Still great images though. "
(So he's probably not returning it)

That's the way led technology works, but lcd (and i think ips) uses backlights.
I have a little bit of light bleed about 1.5" up on the right hand side of the screen... It's about the size of a 5p coin.
I'm not going to worry about getting anything done about it I don't think. I only notice in in the settings screen, and I'm rarely in there. When I'm in portrait mode, I just see it as a 'glow' on the taskbar.

Ah yes, you're right. Was thinking Flouro. In any case, light is leaking reflecting off small gaps from the edges and into the upper layers.
Have you ever tried to completely seal out all light out of a room? It is insanely difficult and amazing how much gets through.

Typicaly there are two light sources - at the bottom and at the top of the screen (or on the left and on the right - my LCD monitor has it that way). Sometimes there is only one source - on the bottom mostly.
I'm not sure about this but as far as I know LED backlight works the same way - it's only at the top or bottom in most displays. Some better LCD TVs with LED backlight have more LEDs behind the screen - but it's pricy to do so I doubt tablets will have it that way.
I have a reasonable amount of light bleed on my Transformer. Areas on the horizontal and vertical near the home button.
In addition, a couple of spots on the right hand side vertical.
No major drama, called Comet and they are sending me a replacement, though not until next Thursday when they predict they will have more stock, though given what I have been reading today on various sites, that date could slip a little. Doesn't matter though, my replacement request is logged and will happen when it happens.
On the down side, by the time I get a replacement I will have spent ages getting it just how I want it.
On the up side, I get to have all the fun of setting it up again.
On a side note, having cancelled a preorder for a Xoom through PCWorld and bought the Transformer, I finally got to play with the Xoom on the shelf today.
Definitely made the right decision.
The Transformer just feels better made, and despite the fact that the Xoom has excellent viewing angles, the screen is not a patch on the Transformer, oh, and did I mention the small fact of 100 quid!
The reason I started to asks about this is because I'm a bit skittish about light bleed, having once had a monitor and the store just thinking i was nuts "there is nothing wrong with this monitor its just you" - thanks a lot! Humpf.
Had to use my transformer in the sun today and all went well. After arrviging at home I restarted the device and I saw overblown white lighting on the right left and top bottom side. Although you can only really see it with a dark background this thing is really annoying, I didn't do anything wrong like leaving my transformer in the sun or stuff like that.
So is this software or display related? If its the later I am going to return it to Asus and asking for a new display, because otherwhise I really love this beauty almost replaced my casual everyday work notebook.
How big and bright is it? If you're seeing it only on dark backgrounds, it sounds like it's light leak; which is pretty common on these types of LCD panels. I think the spot has always been there and now you notice it. Being out in the sun had nothing to do with it.
While light leakage is considered common, we can replace the panel under warranty if it's severe enough.

Thank you, I have tried to make a screenshot but it just doesn't show the lights, so I am going to try it using my handycam tomorrow, will update this thread then and post it here.
Yeh take a photo with a camera. A screen shot will not be able to show the light leak since it's the actual panel that's affected and not what's on the display.

Just purchased a brand new Galaxy S6 32GB FLAT in white today. Right out of the box, especially on a white background, I noticed that the bottom half of the screen shifts into a more warmer tone. It's most visible on a white background, where i can actually see the transition between the two colour tones. Other colours are affected too, but not as noticeable. Please refer to the attached screenshots, (Ignore the diagonal lines running across the screen, caused by the camera artefact).
My question is, is it normal? Can you please check yours and provide feedback? Thanks in advance
I have the same
Its a common issue. But it shouldnt be like that. You should get a replacement

Dude this isnt severe. Ive seen enough amoled displays having worse tints and stripes. Yours is much better than them. If I was you, I wouldnt settle for this. Replace it or get a refund. I have severe ocd about my phone. I need it to be perfect. Luckily the S6 that I have has a very good display. A perfect one. Get a replacement asap. This isnt something normal.
Im ordering my 2nd replacemeny soon. My first one was yellowish and uneven like yours. My current one has a horrible pink tint. Try 3
Welcome to the club: http://forum.xda-developers.com/galaxy-s6/general/getting-replacement-s6-due-to-screen-t3074865
I took my phone back to the Samsung store and got it replaced by the manager there. The screen looked fine when i first looked at it in store, but soon after taking it home i realised that this second unit has a yellowish tint on the right side of the screen. Going back tomorrow for another replacement.... SIGH!!!!!
My third replacement from the Samsung Exp Store is.... a KEEPER! This unit has a much better even backlight and meets my expectation! After going through that trouble, i'm happy to say that I'm a a happy camper

Do you think my phone has the same back lighting problem or tint? been ocd for a while now since I got it yesterday.

Looks all right to me, but then again we all perceive things differently. My current unit is not perfect, there's still a green/blue tint to it, but it's tolerable. If you cannot tolerate it, then keep exchanging until you find one that you can tolerate with. Keep in mind though that you won't find a unit with 100% even colour hue; it's the limitation with AMOLED displays. All the best!
I have the same issue
I have the same, but much less severe than yours seem to be. I don't notice it at all with normal use, only super slightly on bright white screens. If it really looks like it does on the photo, I would get it replaced.

Light bars on black wallpaper
I have the following issue on black wallpapers.On top and bottom there is a lighter bar.This appears only after applying the wallpaper.Viewing them with Quickpick there are no bars.Same in Nova and TW after applying it.Tried attaching a screen but the bars are not captured.What could it be,a ROM issue,a low DPI?I have the DPI set to low.Also on brighter pics you can't see the bars ,after applying which makes sense.
White uniformity - Is this the jelly effect and is it normal?
I got a really good deal on a used Tab S6 from Amazon and I love the tablet but there is weird tinting thing happening on white screens.
When viewed slightly off-axis the tint goes blue.
Makes me nuts when reading NY TImes and edges of white screen are tinted blue.
The effect changes when viewed at different angles and seen without screen protector. It is tough to photograph but hopefully you can see what I see.
Ignore the moire in the middle of the first shot - that's a screen protector... Look at extreme edges of screen.
Thanks and pardon me if this has been answered before - I've searched and couldn't find this issue.
Now this really isn't an issue at all but it was pointed out by my friend. There may be other ways of noticing the same but here's how I do it.
Sit in a dark room, as dark as possible (best at night).
Increase the brightness to maximum.
Open any video on MX Player, pause it and zoom out (decrease video size) as much as possible.
Observe the corners around the chin of the device. You should see some light leaking through.
Now of course this isn't an issue you'd encounter normally but it just kinda freaked us out. Any idea what might be causing it? I have no technological knowledge about displays except for the fact that pixels are turned off for black areas in AMOLED displays. We don't have navigation keys backlight either.

There should be no light leak/bleed on an AMOLED screen phone, that is common for IPS screens.
Did you get the phone from the official site?

Doubt it's possible to have "rogue" pixels but I will have to see for myself when mine arrives. But my friend who has it never complained about it, so I have a feeling only a certain batch of them might have this issue.
There also might be a chance it's related to software, so did you try using another rom?

It certainly is weird. I mean that light bleed doesn't exactly appear to be "rogue" pixels either. Plus it's rather too dim to be noticed unless you're sitting in an absolutely dark room with your brightness maxed out and about 75% of the screen totally black (which would rarely ever happen). I believe it could be possible that every unit has this but never really has been noticed by anyone.
The issue isn't that great for me to switch to another ROM and test it. Just wanted to bring this to everyone's notice. I'm on OOS 5.1.11 (rooted)
Yes, I ordered 2 and they were both defect so I sent them back. I did not send them back because of this tho, however i also recognized that both of them had really bad uniformity issues and it looked like the edges were bleeding. I observed that on a white background. I am living in germany and ordered from amazon, the second one got dust in it's front camera lense, when it arrived and the first one was emitting a loud static noise, like coil whine. It's insane, I just want a proper working phone. Not sure, whether I should order a 3rd one.

Wow that's a really big let down on Amazon's part to send defective units, and that too twice! However, I checked my screen for any such uniformity issues both on black and white but didn't find any such except for this one. And I repeat again, this is barely noticeable and is visible only when you're in absolute dark, with maximum brightness on black screen.
Although such a thing is ignorable but it's something which isn't really expected from OnePlus.

Hehehehe.... I'm sure it'll be just fine! And congrats on getting your new phone (even if you're about to get it). Nevertheless it's a very decent device :good:
The punch-hole's circumference is noticeably jagged. Please zoom in on the image attached. You'll see that the boundary of the punch-hole circle is not smooth. Apologies if the image does not convey my point. You may check you own device's punch-hole on full brightness, on a white background to get the idea.
I'd like to know if this is the case with every unit of Pixel 6a or if this is normal.
There's also some very tiny amount of green-tint/rainbow-ish effect around some part of the circumference of the punch-hole, although it is barely visible and is probably just my eyes' fault.
Thanks in advance.
Are you talking about the pixels themselves on the display?
Pixels are square. The punch hole is a circle, so it's going to look like that if you zoom in enough.
We don't need no stinking laser...
Lol it does look a bit crude but then again I never scrutinize my Samsung's stupid hole that closely.
Mine looks fine and so does yours. Yeah if blow up your macro shot to 3x can see maybe not laser perfect but the circle is also cutting over pixels, so that's to be expected. I don't notice any rainbowing on mine

Run Screen Test to determine the color integrity of the pixels around the hole. Colors should be uniform. I always test the display on a new phone and as it ages.
Thanks for the response. I might run a screen test, although the screen seems perfectly fine as it is from average working distances. I was probably being way too ocd about the whole issue.

An interesting thread. The flashing proximity sensor threads were common a while back. One or two flashing pixels on phone calls drove some Samsung users mad. Never even notice it before
Always a good idea to run Screen Test to help spot display issues especially on a new device or one that's under warranty.
I test my 3yo N10+ every month or two. It's bright so don't linger too long when doing it.
Any display pixel anomalies are easy to spot.
Any wrong color pixels at the hole would confirm you suspicions. With 20/10 vision and no magnification though the hole should seem smooth, at least on a N10+.
