[Q] White Glow on Dark Screen - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

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.

if possbile post the screenshot.

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:
http://hardforum.com/showthread.php?t=1546595
There are also youtube videos showing it, like this one:

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.

Display Color...

So I have had my g tablet for a couple of weeks now and I have noticed that my display color seems a bit off. Mainly being the whites, they have a red tint to them but it is really across the board. Any ideas? Do I need to call Viewsonic for an RMA? What?
Also, just a side note, my wife just got her Ipad2 and I must say that is a slick looking device. And you gotta love that display with those WIDE viewing angles. I am not an Apple person because I don't think some program should be able to rule what I can and cannot add to my devices.
Update: So I think i might have figured out my issue. Apparently the screen is tweaked because when I put pressure at the opposite corners, upper left andlower right, all of a sudden BAM nice and bright. We will see how long this lasts.
Update #2:
Here are some pics of the device both before and after when the screen is acting up. Now it just seems like it is dark with the red tint now...
Oh weird, I've never seen something like that before. Is it still fixed?
Nope, it constantly switches back and for.

[Q] Odd display issue when viewing black backgrounds in dark surroundings

Hello XDA,
I've searched around for this problem a bit, and it seems this issue hasn't been brought up anywhere. If it has, then I apologize.
The S2 has an awesome display with great colors, blacks included, but I noticed this issue one night when I was watching a film on my S2. When the display is showing black/dark images you can clearly see what appears to be glue smudges all over the screen, especially along the rims. It is only noticeable when there's little to no other light in the surrounding environement. Increasing brightness seem to worsen the problem.
It is hard to describe and very difficult to capture on camera but I made an attempt. I can't post links yet it seems but here's an imageshack url:
img842.imageshack.us/img842/5420/blotches.jpg
The image was taken with a Canon 450D with 20 sec exposure (hard to focus when it's that dark I'll tell you). Edited slightly in photoshop to cut down the size.
Here you can see the general color of the screen (gray-ish) and some of the blotches of (what I'm guessing is) glue in the back. If I had to guess I suspect the blotches might come from the capacitive touch layer of the screen. Is this an issue or is it to be expected on phones like these? It's not a major problem but it's actually quite annoying when you're watching a film/youtube clip/playing a generally dark game or whatever. Should I return my device? I've used it for just about a week and a half.
Thanks in advance for any help.
i have this too, its the AMOLED display. you can turn the screen off and on and you'll see it go off n on. not the sgs, but amoleds generally. my omnia HD had this too (1st gen AMOLED)
the blacks are not 100% black i say
Im having this too, nothing to worry about this as it doesnt disturb the beautiful display of this mobile.

Screen problem: slightly visible moire-effect like pattern

I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?

[Q] Folks, is this normal? Odd patterns on black screen

Having played with my S III for a day now, I've been mighty impressed by the vibrancy and contrast of the screen, however, during the evening, when the lights were off, I couldn't help but notice something peculiar.
To be clear, I have no clear dead or stuck pixels and the issue occurs when the device is on, displaying a black screen (though I first noticed it in video playback that had black borders). I'm unable to capture a shot so I'll explain this as best I can.
When on a black screen, there is a faint glow, when looking closely, there are patches of very dark segments throughout the screen that are true black, as opposed to the general glow of the device.
Does anyone else experience this? Is it normal?
Many thanks
Do they look like black splotches that can only be seen when viewing a black screen.in the dark? That sounds like the same problem all vitas have, something that is unfortunately a side effect of oled screens. My current phone, a samsung wave, doesn't have this issue though I've read that some other phones like previous galaxy s models produce the same problems. Bummer if that's it since I hated it in the vita

Yup its on all amoled devices starting from sgs 2 but its less on some and more on others but still I don't think it hinders usage of the mobile
I have this too and find it quite annoying (even though you barely see it, only when displaying a black picture and in dark environment).
Would be interesting to know whether really all S3s have that.
Arg, curses! Yeah I didn't notice it on my SII which is why it was such a shock on the SIII. It's only noticeable in a pitch black room but sadly now I know it's there I fear I'm going to be picky
I hope it's not the same problem existed on all galaxy tab 7.7 models which you could see circles and spots on a dark background in a very dark room. My nexus s and sgs2 didn't have it but it was so annoying (for me) on tab 7.7 which I returned it and never got another one. Take a look at this thread: http://forum.xda-developers.com/showthread.php?t=1463622
I hope it's not on all models of sgs3,I'm planning to get the 64gb model...

Speculation and more speculation... for once I would enjoy if people posted some evidences when complaining about an issue with this phone..
had this uneven black and white patches in my sgs2. it didnt bothered me much frankly
I'm wondering if this is due d
To the difference between amoled plus and amoled(pentile)....pentile screens can look blotchy, more so than the amoled plus screen

What is so annoying about it ? I bet that no one is looking at a black screen for more than a few seconds in a completely dark environment.
Try this: light up a few pixels on the screen and tell me if you still see the patterns. I bet you don't! S2 has the same "problem" and the thing is that if you switch to landscape the patterns dissapear and re-align. I guess it's how the amoleds work.

If you check the pics in the thread I posted you can see many pics of the problem on tab 7.7. It needs a DSLR with good exposure abilities to make the problem viewable on a pic ( though it is noticeable with the eye in the aforementioned situation ). If the problem is as widespread as it was on tab 7.7 this thread will be explode with pictures and complaints. *fingers crossed* that's not gonna happen hopefully.

It's impossible to see in the light/day time.
You need a pitch black room, with screen test app turn to black screen,,,slowly the wriggly lines and patches will show up. It is annoying yes - 2 phones were exactly the same defects. Each phone had it's own wriggly lines etc.
Tried to take a picture but it's nearly impossible.

General The Display issue Thread....(color fade, flickering, tints)

Hey guys,
I havent seen a thread related to display issues. In 2 german Forums I found threads about various issues. From Color fade, to overall greenish tint or flickering screens.
Sadly I am very picky with display stuff and my Display isnt perfect either. I mostly use relatively low brigthness settings (around 30-40%) and on dark mode especially the settings menu has a color fade from dark grey to dark blue. This cant be seen on any other color.
Its easy to see in a dark room, the brighter the room the lesser you will notice.
To easier check: use telegram, with its blueish theme its definitely way stronger fading there...
For a phone thats 649€ in germany thats unacceptable for me. My P5 has a slight warmish but perfectly even colored display and thats what I expect from a P6.
What about you? Can anyone check their display if thats a common issue?
Hi,
i have the same issue, also a device from germany.
Even when booting when everything is white, I always have multiple changes between white and blue in the display.
I'm at work, I try to take a picture when I get home.
Please do, Id really be intersted. Sadly we cant do anything about it...
Anybody have the green ish tint on a black screen issue? Seen a few of those floating around as well...
Similar issues with my screen, also from Germany.
My first OLED screen had been with the Galaxy Note 1 and I hated it for its issues. Always bought devices with LCD screens afterwards.
The Pixel 6 is my first OLED phone since and it is having pretty much the same issues my Note had 10 years ago
Great phone so far (Android is still a bit buggy), but the display is quite a disappointment for me personally, at least for brightness levels below ~50%...
Is it just me or are most of these issues regarding the display coming from Germany? Please can people state what country the device was purchased from if they have this issue
Wow @Abnovitas thats really really bad. Sadly till now everyone seems to be from Germany...
I just finished chatting with Google's support.
They are going to replace the phone, but I'm still waiting for their email with instructions.
But first they walked me through some superficial settings (disabling Dark Mode and some accessibility stuff, like Color Inversion...) and then tried to talk it off as a normal property of OLED displays, which I didn't accept to this extent. But hey, that's probably just Google's policy.
Let's see if this was just bad luck in the OLED lottery.
For me its too difficult to take a picture with dark screen. The color change is slightly less than the picture from @man1acc
But i have problems with white color, it is light grey and i have green stripes on white, this is also very very difficult to make a picture.
Here you can see it a bit, but in real life it is much stronger
This is how my display looks like. Quite disappointing, Google has the same problems for years. But the phone itself is very well built, so maybe I will keep it. Bought the phone in Germany.
I have some rainbow effect which is mostly noticeable on white backgrounds. Hard to capture but found it is quite noticeable with an external light source. In this case my monitor. Anyone else have this or more importantly for a RMA, don't have it?
Pixel 6 when on a black background the right side of the display has a green tint shadow effect kinda worrying as it's not present on the left side and seems to only appear on darker backgrounds like when pull notification tab down or in a app (like xda) with black background very noticeable , or is this just standard now for Oled displays it's not the first phone I've noticed this over the years just curious if any pixel 6 owners see similar or should I get it exchange ? Added pic not sure if shows that well though

Not normal. Each pixel is controlled individually.
It maybe hardware or firmware.
Sounds like the display control matrix wasn't designed properly or is defective.
Your screenshot isn't showing it so neither should the display!

Unfortunately not true. If it's an issue with the display, a screenshot should never show it. But it can be visible when a picture of it is taken.
My Pixel 6 (right) was bought first day from the Google Store. I'm in the USA. It has a very strong dirty red tint at the bottom and a garish green at the top. Easily visible at 60-70% brightness and lower. Here it is compared to my Pixel 4a (left), shot on my 3a. Haven't had uniformity issues this bad since my OG Pixel (which got replaced).
Waited to chat with a support rep for an hour, chatted for another hour, and have an RMA device ordered and on the way.
Maybe are cross to dark side lol
That was a joke id never cross to the dark side lol and tint only seems visible when in certain dark mode apps and not actually navigating around the phone xda app is worse lol so don't think hardware issue tbh
