I just got my refurbed Tab yesterday. I've owned many tablets over the last year, but I've never experienced a soft kind of glowing effect on dark parts of the screen (like in a dark scene in a video, or even the bottom control bar) when viewed at any angle at all. The image almost becomes difficult to see unless you're looking straight ahead. I only notice this when there's little to no ambient light in the room (which is when 90% of my tablet usage is- reading or watching a movie in bed).
I compared with my touchpad in the same scenario and while there was a *very* slight glow, it wasn't nearly as bad as on the gt 10.1.
I found next to nothing on Google about this. Does anyone else get this, or do I possibly have a bad refurb? It's a shame because I'm completely in love with it otherwise...

Is it coming from the sides? If so, it's LCD screen bleed. It unfortunately happens with backlit LCD panels. It doesn't appear to be too common with the Tab as I haven't seen it mentioned before. I'd send it in for repair while it's under warranty. They changed the screen design in October and you'll get it back with a better display then it has currently.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
No, it's not from the sides. There's no bleeding. It's on the screen itself. It's almost like kind of a ghostly white glow on top of the dark colors on the screen. A shimmering effect, maybe? I'm not sure how else to describe it.

Hm. I guess i'm not explaining it well.
While it is on the screen itself, it's only when you tilt the device to the viewing angle isn't straight on.
Here's a thread from a different forum discussing it:

I just compared my G-Tab with an ASUS Transformer, and it was still there on the Transformer, but not as bad as the G-Tab.
Hey fellow EVO lovers how's everyone doing, this is my first thread ever so I hope I don't get bashed too hard, anyways so my issue is im having light bleed from the home button and I know its a common problem, my question is what are you guys doing about it exchanging the phone or just dealing with it? I know its not a big deal and doesn't affect performance but its been bugging me lately, is there any mod to dim the backlight. I really don't want to exchange phone since this is my second one first one had lifted screen, also does light bleed get worse over time and does it affect battery life at all, thanks for any input and yes I'm ready to get flamed
Does it bother you? If so, get it replaced. If not, don't worry about it.
I had the same problem but it was only noticeable in a dark room with a black background... I changed only cuz I have ocd when it comes to things like that.

Yeah, I have it, but I only notice at night, when I first open my Kindle app (black background). I am just going to ignore it, it's such a minor thing.
I think I'm going to go ahead and keep it, its really not a big problem and. Is only noticeable at night on a dark back ground, I just wanted to make sure it doesn't get worse over time or effect battery life, thanks for the input guys
Yea I have that problem also, but as soon I put a less bright background on the cell phone I haven't noticed it
Light bleed? What is this light bleed you speak of?
I got my phone last night and see no lightbleed at all. Even at full brightness in a dark room there is no light bleed in the slightest. There is a TAD bit of light barely coming out where the camera button is....but if that is what you're talking about, then you need to get a life.
EDIT: Oh, I see it near the capacitive buttons... You barely can see it, unless your brightness is maxed and are on a black screen. Big deal...the screen is still 100x better than that pentile SIII screen.

That is most likely not what he is talking about. The common light bleed is two white streaks of light that shoot up from the home button. It is more than what you described.
My phone had slight light bleed from the day I got it... Which was never a big deal. For some reason it is getting worse, I can see it in the daytime sometimes. Would this be covered under sprint I insurance, deductible free?

Yes that is what I am talking about I get 2 streaks of light coming from the home bottom on mine it's only noticeable on low brightness with a dark background, its not really a big deal I only notice it at night.
As far as sprint insurance it should be covered but I do believe you will have to pay deductible unless you are within the 14 day return period in which case they will replace it for free
My main concern was to make sure battery life wasn't affected by the light bleed because I'm getting way less battery life with this EVO than I did with my first evo, I'm getting about 12 hours now compared to around 20 before running same Rom,settings, apps

I'd say if it is affecting performance, functionality, or battery life, it is worth replacing. If none of the above are affected, then I think the headache of going through replacing it would be worse than the problem itself. At the end of the day it is up to you.

Damn it. I just noticed that my phone has this, as well. Don't know that I want to have it replaced as everything else (even those issues that the majority seem to have), so far, is working perfect on this device.
Will Sprint replace with no questions asked for this reason? Obviously, if I decided to, I would have to relock and return to stock, right?
First things first..
My S6 Edge got scratched by this clear-cover issue. Got a free screen replacement from Samsung. Looks like new now, but! The capacitive buttons light are uneven, the left is brighter than the right, as much so its anoying. No real big issue since I keep them Always off (they fill 0 function since they are dark untill pressed (wonder how samsung thought there? )
Not easier to find them if they are dark until pressed I mean..
Back to topic. Samsung do not care about that, and my store want to send it to service again (h-ll no! I rather keep them off). Would be great if brightness could be individualy set on them, would solve the issue, dim the Bright one down.
Anyone else having this issue? I wonder how far I should push this, I have them off so it really don't matter. but it bothers me to just know it Had Galaxy S2,3,4,5 and now 6. This one has caused me more problem in 1 month, than 2,3,4,5 together in all thoose years...
What's up everyone, loving this k one but how about that screen bleed though!? Yes I know there is a similar post about this, but I want to make it only about the screen bleed issue and anyone experiencing same? I am about to go get my third exchange in less than ten days
I just checked and the only noticeable bleed I noticed was by the top left of the second screen but it's small. Main screen seems ok, to me at least.

That's true, and for me it's fairly noticable on the top left, along with under the two front facing cameras there is bleed as well for me. This is my second phone.
Could be like the g2x lol
It's definitely there in the top left corner, but there's no way it would bother me enough to go exchange it.
Same here, if only there was a way to invert the color from BLACK text on White backgroud, to WHITE Text on Black Background. The fade would not be noticeable.
I went through 2 V10s and ended up returning both and going back to my M8. Basically what I noticed was slot of backlight/screenbleed issues when in immersive mode of an app. Like a book reader for example. If the background color is white, up at the top of the screen there would be a gray/black hue leaking through.
Of course once you notice it, you see it in other applications that go into immersive mode. I think there is something happening where the 2 displays meet at the top when immersive mode kicks in.
It's mostly only noticeable when the screen is like 60% brightness or less.
Unfortunately that was a deal breaker for me, even though the rest of the phone was great.
What sucks is that I'm going to have to fight a restocking fee for this problem even though t-mobile store reps saw the problem as well

I was thinking in maybe doing the same but getting maybe the HTC m9 or anything other than the Samsungs. Hate them. I will be going today to get my third new exchange since I still have seven more days left. Gets very annoying all this screen bleed issues. This phone is so beast in all other aspects. Camera, sound quality, and love the software but not as much to stock like nexus line.
I have a post here with dead pixels issues, the replacement T-Mo sent me not only had dead pixels as well, but a terrible bleed where the two displays meet. It is only noticeable when you look at the display from an angle, for example phone on the table and you have a light background you see a dark spot there, once I noticed that its driving me crazy. LG quality control is a POS IMO. This phone rocks, but is plagued by stupid QC issues.
There is nothing you can do. All phones will have the "second screen bleed" due to how it's designed.
There are two backlights. First is the normal backlight that lights up the entire display (there is no "second screen" - it's a single LCD panel). Then, there's the secondary backlight - a single white LED on the left edge of the "second screen." This single secondary backlight LED is injecting light through the left edge of the second screen and is not attached to the main backlight diffuser, which is why it lights the screen so unevenly. There are certain times when that secondary LED is on and when it is off. When it is on, it adds extra light near the left edge of the screen, which makes the notifications in that area brighter.
Try this. Turn on the Camera app and observe the buttons that appear on the second screen. Notice that the left-most (or bottom, if you hold it horizontally) button is NOT brighter at all? That's because the second backlight turns off when the camera app is running, and you only see the main screen backlight, which is even. Exit the camera app and you'll see the second backlight turn on and the bleed return. Open the camera app again and you'll see the bleed disappear, as the second backlight turns off.
Do another test. Hold the phone at an angle so the bleed from the second backlight is clearly visible, then go into the settings for the second screen, and turn it off while watching the left-most edge of the second screen - you'll see the "bleed" suddenly disappear, because the secondary backlight turns off (even though the main backlight is on). Turn the second screen back on while watching the left edge, and you'll see the bleed come back as the secondary backlight turns back on.
Yet another way to see it - power off the phone, then power it on while watching the left edge of the second screen. During initial boot, it will look perfectly even, no bleed, because the secondary backlight is off. But half-way through the boot process, the secondary backlight turns on, and you see "bleed."
Now, when the main screen is off, the ONLY thing lighting the second screen is the secondary backlight, so ALL you see is bleed (since the main backlight is off) which looks horrible.
The reason you don't see bleed at all in TWRP is because TWRP doesn't know that there is a second backlight and therefore it doesn't turn it on, since it doesn't know how.
To get rid of the "brighter left side" problem when the main screen is on, all LG has to do is issue a software update that turns off the secondary backlight when the main screen is on - I'm surprised they overlooked this obvious problem.
And here's the kicker - you know why you don't see the second screen bleed on the demo units in stores? Because the Retail Mode app turns the secondary backlight off, just like the camera app.
here's my issue, called again to T/mo and they're sending another RMA..Apart from that am having a defective proximity sensor...will update when the "new" phone arrive
That's not screen bleed. That's where the edge of the lcd panel meets the edge of the bezel around the front facing cameras. It's an unavoidable shadow.
I'm really picky about my phones, especially the screens, but I think you're honestly expecting the impossible. They can't NOT make a shadow there, given the arrangement of the secondary screen backlight and the camera bezel.
If that's your biggest complaint about this phone and the screen, then I think you're being too picky.

I know am picky, we all should be with a $600+ smartphone, in the highest end gamma quality control must be precise. Apart from that I already posted a dead pixels thread and this one has dead pixels too...take a magnifying glass crank the brightness to 100% and watch very carefully in a dark, this is my second V10 and a third is on the way
Now dead Pixels are not acceptable. But that shadow will always be there no how many times you exchange it.

That shadow was not there on the last phone and its really annoying cause it distorts any solid color that's displayed there, also it's only a "shadow" with light content, it's a bright spot with dark content. It looks worse in real life than it does in pictures

That means our models r very radically different.
way much more of an extent than I have been realizing.
Or...u have an adware prob or it's hidden
I think when it comes down to basics...each flavor has it's own heart.
Yet..No matter the carrier and especially when it's a basic LG/LGE setting....it shuld b on all.
Forgive my lack of correct wording....
I bet if u can't see it ..the ..invert....setting maybe just hidden
Again...u r stock?
K now i think....
You should Try searching for "invert" with QuickShortcutMaker app https://play.google.com/store/apps/...G6PnXP4eFRw4Tw9vg&sig2=ujB0W4bySmI1c5Qzvof0KA
No I'm not pushing the app...I'm hoping it may enabling u to see the setting.

You need to take use of their 3 RMA in 90 day policy and switch out from the V10 than.

I noticed the same thing on mine. I hope they will fix it with a software update. I've noticed that it doesn't seem to happen as long as the second screen is active.
I'm experiencing either a defect or an unfortunate feature on this tablet. I just took delivery of a new one, and while viewing any solid colors besides grey on the screen everything is fine (also no dead pixels), but I'm noticing what appears to be slight backlight flickering/pulsing whenever grey or light blue is shown on the screen. It seems to be PWM (pulse width modulation) of the leds, but I can't be certain it's a defect or just the unfortunate way these tablets' led screens are designed. It's a very subtle but consistent and annoying pulse, but it's definitely there. Can anyone confirm that PWM is what's going on with these tablets or if this is a defective screen. The screen doesn't pulse at all on any other colors solid or only partially filling the screen or otherwise.
I haven't noticed anything on mine, though I tend to keep the backlight fairly low (17%).
One thought though which is why I'm saying anything, I remember on the nexus 7 there was an issue with one of the friction pins not connecting to the back of the case's antenna fully sometimes, which would cause the radio/wifi to suck extra power resulting in backlight pulses... have you tried turning on airplane mode (disable the cellular) with wifi off to see if that makes a difference? Though it would be odd if it only affected the one colour... I suppose it could be your ambient light source too, does it do it in sunlight?

Good idea! Unfortunately, killing the antennas doesn't affect it. And there's no ambient light sensor on the g pad x, so that's out as well I'm so disappointed because there are not dead pixels and only very little light bleed in the corners too.
I didn't mean ambient light sensor would be the cause, more that perhaps you have bulb/s that cycle at a specific rate at a certain colour range that would cause a subtle flicker, I always found those big long roof fixture fluorescent tube lights bad for this sort of thing... I notice some "out of the corner of my eye" subtle flickering on my PC LCD when I have the one CFL on, but not when I have the other LED lamp going instead for example. I just tried a LCD screen tester with various solid colours (cyan, blue) and the only 'flickering' I'm seeing is if I actually move the screen, this panel has some waviness in it that is visible when the screen is off and you angle it just right under a light which seems to pop out on these blues with the backlight turned up - but only when the screen is physically moving. Definitely not a perfect panel, but for me nothing like what you are talking about.
I'm outta ideas though, unless you are running a custom firmware and it does something different than what my stock does.

edit:/ just read that RFD post from the other thread, and I definitely notice a flicker when in nova's app drawer. It seems to occur only right after I move the tablet and only noticeable at higher backlight settings, if I set it down flat and don't move it, it doesn't do it. Perhaps related to the gyro sensor? Something not isolated fully/properly would be my guess. With the wifi turned on, it also does it along with the activity up/down arrows on the logo... now that I've seen it I wonder if its going to bother me on lower brightness levels now :silly:

Thanks for checking. I tried the airplane mode setting, and I swear that fixed it. But then it came back after a few more toggles of data/wifi. Given that you're seeing it too and that others have reported seeing it as well in the RFD thread, I'm thinking it isn't a defect but rather poor design. There's little chance it would be this widespread and only on the exact same color combo for everyone. I think most people just never notice it since you're rarely just looking at a solid or mostly solid grey screen. I wonder if there's a way to disable the gyro on a stock/non-rooted gpad like mine? For me, it does it regardless of brightness level.
I've seen this on different devices too, so it's not just a G Pad X thing. I wanna say I've seen it on my Nexus 5 back in the day, but I've had many devices so it's hard to remember. But yep, noticed it happens on "grey" colors. It's much less noticeable with the brightness lowered. Never really bothered me so never posted about it.

My guess is it's the led pulse width modulation. It affects some screens more than others, but is an issue with led implementation on lcd screens in general. I'm leaning towards keeping the tablet as I'm 99% convinced that another unit would exhibit the exact same behavior. Glad to hear it isn't a defect, but sad that they did not manufacturer a better screen.

I don't want to clutter this thread any further, but I'm going into a B&M t-mo store to see if I can test this out on a display device to confirm how widespread this issue is.
Quick update on the flicker issue. It's a problem with all the units, or perhaps just poor design. I did a warranty exchange, and the replacement unit had the exact same issue. Oh well. Just time wasted I guess.
I have the same exact issue with the one i got my mom. Fortunately it doesn't bother her too much but it definitely seems to be a design flaw as we also returned it with the return unit having the same issue
Welcome to the world of flicker.
What you are seeing is very common and an unfortunate side effect of cheap reference designs and a don't care attitude.
There are many new standards for flicker but I doubt they'll be implemented. Flicker pwm needs to be in the 10khz range to be indistinguishable to constant current drives.
