Nexus 7 brightness problems

Just got the nexus 7, but...
When I change the brightness through the power-control widget or settings/brightness, on or close to the lowest level it turns off the display completely. I can't see anything no matter what the lighting condition is. Is this a software bug? I don't see how I can turn it back easily.
Another problem, when reading book, the light from the left bezel bleeds and I have a darker top-left corner. It is kind of annoying.
I also have the flickering problem when the brightness is set on the mid brightness... software updated right after startup.

Anyone have the screen completely off when turning the brightness down?
I also happen to have eight stuck (white) pixels...

Yeah, I have a very similar problem to what you described.
Check out my pics.

My backlight bleeding is very similar.
Does your screen get completely black when the brightness is low? Now, even when I turned on the automatic, it gets complete black. Is it just me or everyone else the same?

No, it does not go black at min brightness here.

I just got the Nexus 7 and the light bleed is Horrendous. I have owned a Asus Transformer before and expect some light bleed but this is really really bad. Like WTF

Holy cow... If mine arrives like that I'll be requesting a replacement.. That's insane!

Mine looked exactly, so I went back to staples for a replacement. Luckily, they have one left. The bleeding on the new one is unnoticeable and the brightness settings are all normal.

Wow. I thought my transformer bled light bad. I'm not feeling so bad now. Of course it has some other weird issues, but has been mostly reliable. If it acts up too much I'll just send it back. I've had it for almost 30 days and can't find any real reason to take it back. It reboots every once in a while if it gets overloaded or too hot (did it today in the sun..of course I had it overclocked too.....) and I've opened the dock to see that it has shut down for some reason, but its not a huge deal. Other users have reported the same, so clearly something isn't perfect. I came to this thread because I heard that the nexus has huge issues. I was curious to see what people were reporting. if I got a nexus like that I would be p****ed! There are reports of them locking up on startup. My transformer just keeps chugging along. Really I've had more problems with apex launcher than ICS on my tf300t.
edit: the light bleed is barely noticable on mine actually...only in darkness does it seem bad. I heard ips displays have issues with that, so took it as good enough for "spec" and really its not all that detractable unless I sit in perfect darkness. Video looks pretty great on the display.

[Q] shadowed/darker screen area, is this normal?

Hi.
I received my Nexus 10 yesterday and, after a few hours of use, I've started noticing a shadowed/darker strip along the top of the display (the side that holds the front camera). Take a look at this photo:

}
The effect is not very noticeable in this image (I'm not a good photographer), but to the naked eye is pretty obvious. The photo at this post shows a similar effect (the left side is darker than the right).
Does your Nexus 10 also suffer this problem or mine is a faulty unit and I have to return it?
Thanks.
Cheers,
mprost

Can't really see it on the photo. Is that a white screen on full brightness?

Yes, it's a white screen on full brightness, sorry for not pointing that out before. Maybe the following photo shows the issue better (full brightness again) (I know it's difficult to see it, I look at my N10's screen and I see it clearly, but then I look at my photos and the issue is not that obvious):
It's the shadow along the right end of the display.
Thank you for your help.
Cheers,

The screen looks a bit murky on the first photo. Second one doesn't look too bad though.
The issue your having might be because the backlighting isn't uniform.
Can you take a photo of a fully black screen to see if backlight bleed might be causing the issue.

Well it's nothing to do with backlight bleed then. The bleed on yours looks quite good btw. I assume it's completely unnoticeable at 50% brightness. Any chance of a photo at 50% brightness for comparison?
I'm not sure what else it could be atm. Is it only noticeable on a white screen or can you see it on other colours too?

I first noticed it just browsing the web and I can definitely appreciate it with other colors besides black, any colour in fact, is like this area was dirty or, more precisely, slightly tinted or poorly illuminated.

Got the same issue on my N10. Especially noticeable by reading in portrait mode.

I asked for a replacement, which have just arrived. The new one has the same issue BUT is less noticeable (I have them both side by side right now, I could take photos if somebody is interested). I think that if the replacement unit had been the first one received, maybe I wouldn't have noticed the issue (who knows).
Unfortunately the new one has a dead pixel, so I will also have to return it.
Cheers,

I'd appreciate a photo, thank you very much in advance

No problem, there you go, the one in the left is the first to come, the one I think suffers from the issue the most; the one in the right is the new one, the one with the dead pixels (although, upon second inspection, now I think it may be dust under the screen). The shadowed area is at the top:
The photo has been taken in a dark room, full brightness in both devices.
Cheers,

Thanks!

Light bleed ANSWER FOUND

I got an10 and I would like to know how to tell if there is light bleed? I've seen people speak of it but I don't see where anyone says how to check if I have it and I only have a few days left before I can return it. thanks to those who may help me cue in on this problem to see if I have it.

Download a light bleed app from Google Play and shut the lights off and see.

Fair warning, though: be prepared to contract a bad case of OCD.

NO. WHY?
All caps aside, if you don't notice it I wouldn't look for it. Because once you find it, it'll probably stick to your mind for a long time.

Exactly right. If light bleed is so bad that it really bothers you then by all means return the device and try to get a better one, but if you can't even tell if the problem exists don't go looking for it. All you have to gain is dissatisfaction with an otherwise good device. Watch some movies, use the device as you normally would, and if it looks good to you don't worry about light bleed again.

Or you have the same experience I had. Little to no appreciable light bleed. My first N10 had none, but had a small fracture/defect in the glass (you'll see my image in the light bleed forum).
Second one, a nickle sized but very dim bleed and only seen when in a closet with the door closed and no light.
Acceptable.

Loving mine. I have a small "chipping" in the top glass, also minimal light bleed.

I took another picture the other day in a closet, since the first one I posted in another thread gave the screen a purplish glow due to the angle. Also, the Backlight Bleed app icons were at the bottom of the screen so I turned the N10 upside down for this one. The white icons are overexposed, which I suppose means the bleed in the photo may be exaggerated to some extent, but it seems pretty accurate as to the extent itself. Again, 100% brightness in a dark closet. I'm telling myself I can live with it.

If you go looking for a problem - you will find one. Even if there was not one to begin with.

I am on my 6th unit. I've had it for a week, and I've been using it constantly. It appeared to have minimal bleeding upon opening. After a week of "breaking it in," however, the bleed in the bottom left corner is quite apparent. Anything brighter than auto-brightness and it's noticeable in any setting or on any screen. I'm just tired of gambling with every return. I mean...this is my 6th one. *lol*
Judge for yourself.

Lightbleeding

Does anyone get light bleed on their tablet? Mine is really really bad...amoled should give superior blacks...this is just awful..

The display's not AMOLED; it's LCD.

Wow I would return it, most have little bits in the corners but that's shockingly bad

I think that picture is deceiving as I dont think those two huge points at the top of the screen are light bleed. I tried taking a pic of the light bleed I have (which is 2 small points at the bottom) but when I took a picture it turned out like your picture and made it appear as the whole screen is a disaster.
Unless it is actually like that then yeah return it for sure.

2 little ones is Normal and not really noticeable, I'd say if It's really noticeable and annoying I'd say it's probably faulty
Sent from my SM-P600 using XDA Premium 4 mobile app

Aye just focusing on the lower portion of the screen it still looks like there's 6 -7 bleed points - I would return it personally.

That is really bad and should be exchanged...

Lucky mine is nothing like that either. It only has one tiny point at the bottom right corner when held on landscape. Seems like my unit is actually mostly defect free from many of the issues people have been reporting (no loose grill etc.)

My white 32gb has no light bleed at all, unfortunately my GF appropriated it & bought me a black 32gb to replace it and it does have significant light bleed - quite a lot in the upper right corner and little spots running along the bottom of the screen. Best Buy will replace it but they aren't getting any new stock in for the foreseeable future. Is this more common in the black model?

Mine just arrived an hour ago, no bleed here. Man this thing is fast and the screen is beautiful. Build quality looks great. Still testing. Guess I'll test blue tooth and the card reader. Don't really care about bluetooth too much, it's such a halfa$$ed protocol but I'll test it anyway.
32 GB, Black, USA, Wifi version.

you could set the tablet at normal setting under normal lighting and see if you notice the bleed. 100% brightness with a solid black background in a dim room is not how most people would use it.

Just finished testing bluetooth. Rock solid, tethered to my Apple bluetooth keyboard and trackpad. No disconnects from either bluetooth or wifi. Even some of the function keys worked. One thing of note. My tablet came with mk1 preinstalled and the box was still factory sealed. I'm guessing it's a newer build.

Coz the latest update hasnt been released yet in the UK.

If I use the Backlight Bleed Test app which sets brightness at 100% and look at it in a dark room it is almost the same as OP's pic. The real annoyance for me is the light in the lower right corner as it is pretty visible when watching Netflix letterboxed movies. I'm still torn over returning it as I figure there is pretty much an equal chance of getting something worse.
Is there anyone who has no light bleed from the LEDs at the bottom of the screen?

Yeah same, I have a few points at the bottom only noticeable when hight brightness and black background so not really bothered considering it doesn't really effect movies or normal usage.
I have some really faint bleed on the ride hand side but have to have brightness max, dark background and the room light off. So once again nothing to worry about.
In LCD's screen light bleed is expected but if it annoys you then try an exchange but sods law you will end up with something worse.

I bought two, one from Amazon, one from Tigerdirect. Both have really bad light bleeds. The one from Tigerdirect is a little bit better, but as soon as I open up camera app, brightness automatically turn up to 100% and the bleeds at bottom are very noticeable and annoying!

Burn-in on screen

I can't believe I have fricking burn-in on my screen! I have had the phone less than two weeks and have been loving it but last night noticed lines on the screen. They look to line up exactly with the thread topics list on the Tapatalk app.
I have been using the app a lot but there is no way I should have burn in happening. It's not like I have even left the screen sitting in one place when using the app. My hypothesis is that it might have happened from using the ultra brightness mode (adapt display with maximum brightness on with auto brightness turned on) in bright sunshine and using the Tapatalk app.
I have googled burn in for this screen and haven't seen anything so I wonder if I somehow have a bad screen. It did look great when I first got it. If anyone out there has heard anything about this or can check their screen on a dark grey background I would appreciate it. Thanks.

Got a new phone and the screen is actually a little worse than the original. Has the same white lines across screen when the brightness is turned down in a dark room with a dark grey or similar color on screen. Sent the replacement back and am going to keep the first one. The lines are actually not that easy to see during normal usage and I really like the phone.

Yeah I have had an s2, galaxy nexus and s3 before this and have noticed some screen uniformity issues before. Never had seen the distinctive thin lines like I see on the two s5's I have examined. I was hoping to have just got a lemon but now that I have seen another new one that actually looked a little worse it has actually eased my mind a bit even though my OCD wants everything perfect.

Know the feeling. It freaks me out every time I use Tapatalk.
They also show up when you use a paint app and fill the screen with +-80% brightness with the screen brightness below 30%
However, they disappear when you turn the brightness of the screen up, (and compensate the black to 80% again) so it's just a bit of an error in the led calibration.
The area below the notification bar also has it when you run the colour tests after dialing *#0*#.
It's more predominantly visible on the S5 and Note 3 because those screens have the highest contrast ratio.
I'm horribly OCD over my devices too. There's a 0.5mm distance-to-screen difference between the edges of my screen protector... It bothers me every single day! >.<

Funny you should say that I just got one of those tempered glass screen protectors and was amazed that I got it on without any dust or air bubbles. Unfortunately it is also off a fraction to one side and also doesn't quite line up perfectly around the home key. I am so tempted to try to fix it every day but I know I should just leave it alone. ?
