Curious as to how many of you have backlight bleed?
Download the backlight bleed app from the Market, set brightness to 100%, go into a dark room and check for bleed.
The first Ace 2 I had had backlight bleed under the 'Samsung' lettering at the top of the display. I went to the store and switched it out, but the replacement device also had the backlight bleed in the exact same place.
Yes, I have a tiny bit of bleed. But nothing to lose sleep over given that this is a cheap phone.

What is backlight bleed?
Looks like this is wide spread. Samsung's fault... Case closed.

Bleed
May I ask how many of you have backlight bleed (yellowish tint when the screen is black with brightnes set to max or at least a higher value) ?
I noticed on boot that my ace 2 has a yellow tint at the top of the scren (under the Samsung logo) and there is a little bleed on the top-left edge.
I attached a photo from top of the screen (sorry for low quality I made with my laptops webcam), here you can clearly see the yellow tint under samsung logo.

Hey xda forum!
I just bought the awesome phone, desire, but i noticed that my screen is blue-greenish tint, compared to my friends Desire. I think i can live with it, but is there anything to do? i've searched for this problem and found that the samsung vibrant also has this problem.
what can i do, is there any way u can change the setting of ur display? turning brightness up helps, but outside, my friends desire is easier to see/read compared to mine.
You may have it set so that brightness is Auto,
Settings > Display > Brightness
It was set to auto but that really look awful
So it is on full brightness now

the amoled screen does have a blue tint, from what i beleve blue led's die out really quickly, Samsung on purpose made the screen to over display blue, and as time goes on, the blue will die to a yellow. So if your phone is more blue today, it will last longer tomorrow. also Samsung tunes all of their displays (TVs and all) towards the bluer end of the spectrum because it gives the display a higher apparent brightness because our eyes perceive bluish white as being brighter than yellowish white even with no actual brightness difference.

thanks for the info, that actually good news followed up on ur info and read about it on wiki.
i guess thats the only way they can expand the life time of old amoled displays.
back to auto brightness
I just bought my desire and have same problem ad u guys. I accepted the fact that blue had a low lifespan, but was still trying to hunt for a solution. After dl many brightness apps I found, Brightness profiles. I started playing around to change the brightness and notice some weird flickness. Example at 74 % it was more "yellow" than on 75%. At 96 % had less blue tint than 100 %. I could see it clear under no light before I went to sleep. So I guess they are defect but Ye, that's my workaround cuz I'm too lazy to return the phone and I like the cool tint now, or well it got better
Just got my VZW galaxy nexus, and im loving it so far, but have noticed something odd: toward the top of the screen (about 1/4 of the way down from the top) there seems to be a very slight green tint, noticeable only when looking at a dark background (like the settings menu).
It's kind of hard to explain, does anyone else have something similar on their phones? Is this normal for amoled screens or should I ask for a replacement phone?
i believe it has to do with it being a pentile screen... well, 'HD' pentile, but still..
i'd say if you try an exchange, make sure you the test the other in store first.
can anyone with a galaxy nexus please post a photo of their phone on the settings menu? (scroll all the way down)

Pretty sure the setting menu is a background gradient with an intended color shift.
But yeah, mine has a blueish/greenish hue if I tilt the phone away or towards me in portrait mode. Straight-on, I don't notice anything.
yeah i am talking about viewing straight on
mine has this greenish tint slightly at the top right screen...
that settings menu then scroll all the way down is normal.. the color is not as dark as the top. I'm seeing greenish tint when on white background
I have a very light greenish tint on the right side of the phone on white backgrounds with text when at low/automatic brightness. The green goes away when I bump brightness to 40%+.
Did you try that?
Oddly, when I ran pixel checker, the pure white background has no green tint to it at all.
Yeah, at low brightness I see a tint/haze but at full brightness, everything looks beautiful.
Welcome to the world of pentile.
I see the same green tint on my screen. I thought it was normal, but I compared it to another unit today and saw that my display was both dimmer at the same brightness level and had a greenish cast and different color temperature than the unit I was comparing it to. I'm not sure if this is within the normal variance for these displays, but my phone certainly looks worse to me than the one I compared it to.
Both units also showed a green/blue tint when viewed off axis but with greater discoloration on mine. The second unit showed almost no discernible tint when viewing a white screen straight on unlike mine.

i have the same problem. Sometimes (usually after a power down and restart) my entire screen is very dark and has a, very obvious, green tint to it. I compared my phone to my girlfriends at the same display setting and the tint is very obvious (especially when i'm viewing menu, text messages, browser). When i adjust the brightness it seems to make it less obvious, but still there. However after certain power down and restart this "green tint" seems to 'go away' only to either gradually re-appear or just happen when my phone self adjusts to "automatic brightness" setting.
p.s. my phone also, had another minor issue of random re-start when listening to music (via google music) and adjusting the sound effects option. After that restart my phones display was significantly tinted and dark. Weird, Either way getting a replacement unit tomorrow.
Mine has a very slight green tint on the left hand side of the screen when at the lowest brightness and viewing a white background.
I normally have the brightness bumped up a bit, but it still bugs me when I have it low
EDIT: Checked pixel checker, has the green tint. I can definitely see it on the keyboard as I'm typing this though
I took my unit in to Verizon today for an exchange. New one doesn't have as significant of color shifting or banding issues.

yeah i got mine replaced the next day, all good now. No green tint, reduced banding, and much better viewing angles (the first one heavily tinted green or pink colors when viewing it from the right or left side, respectively)
Alright, got a replacement today.
No green tint that I can see, almost no banding and the colors don't change like, at all when I tilt the phone.
Now my nexus truly is perfect

Sorry, I find this very hard to believe. *ALL* pentile AMOLEDs change colours like crazy when you look at them at a sharp angle. It's a characteristic trait of this kind of display.
Pics from various angles or it didn't happen. ;-)

Yeah, I was exaggerating, but compared to how bad it was with the other one its crazy. Very less noticeable than my first one

i recently noticed backlight bleed at the bottom right of the screen with the help of backlight bleed test. I am not really worried since its in the bottom of the screen but should i be worried? Is that an indicator of future problems?

Some early builds had some nasty back light bleed that people posted pics of that, if you had the same thing, you wouldn't be asking what to do you'd know. I checked mine early on and at 100% brightness on a black background in a dark room I have some in the bottom right too. Since the odds of me looking at the display at 100% brightness in a dark room are pretty slim and it doesn't affect real world use I wouldn't exchange my otherwise perfect tablet for one that may be worse. I don't think any back lit LCD panel could pass the 100% brightness in a dark room test.

Hmmm that makes sense....I got a moto g which has backlight bleed on its top :/ so i guess its common for all devices :/ wish there was a fix
I got my HTC One recently (last Friday) and it was a perfect phone! no problems whatsoever...
Yesterday i was playing with the phone with a colourful background wallpaper from HTC and i noticed light bleeding from the top (hold it in a angle and you can see a light bar shine through like this:

It isn't that big of a deal but for a phone that costs over 500 euro's here in my country.. you expect that it is build properly and backlight bleeding on a phone at this price!?
I compared 4 HTC's in the store and they all got the same problem
GPe dims the edges of the screen, so it's harder to notice if it's there. I haven't ran sense in a while so I can't tell either, but I can't notice this light bar effect on my phone either. So it may just be that batch of phones.

Got it in in my bottom right corner... very minimal though
Wow, that's massively anal lol.
mine was the whole top screen.. but it doesn't matter, that's just HTC right..? They're known for the screen bleeding, haha..
I've been having this issue on the bottom of the display. It makes the nav buttons look funny and full-screen content is washed out.

Here's mine. Italian H3g branded:
That light bleed above is probably a bit excessive bit you guys have to realize that all LCD screens are going to have some light bleed. You can usually make it less noticeable by using a lower brightness setting. If you are really anal about the slightest amount of bleed you should really be looking into phones with AMOLED displays. That said, if the light bleed is washing out the nav bar at reasonable brightness settings you should try to get it fixed or replaced.
My M8 has some bleed on the top left corner at normal brightness and I'll notice it across the entire top if I go full brightness in a dark room. At normal brightness it doesn't bother me at all.

Hello,
Are you satisfied with the screen quality? Mine has a yellowish tint at the bottom.
I don't see a yellow tint
You mean like this?
https://www.reddit.com/r/Huawei/comments/9wqfrw/help_has_anyone_experienced_this_lcd_backlight/
If yes, then yeah I have that too :/
Not too thrilled about that
I have something similar bleed, but it's only visible a very low brightness, like very near to 1%, I'm using display tester app to see it, with auto brightness in dark room isn't obvious.
Regarding a yellow tint, I think that my bottom half display as a slight warm white, it depends of brightness and the room light, angle that I watch the screen.
