Screen uniformity/heat

Just had my UK Note III delivered, and initially was blown away with the screen..
But when the evening came, and the lights dimmed, the screen auto brightness kicked in, and I've noticed some website backgrounds which are lighter shades of grey seem to show a slight cream tinge mainly around the middle of the screen..
I don't know if I'm being too fussy, the screen does seem 'warm' around the middle as well, it's much cooler at the bottom of the screen, where it seems to have no tint at all..
What's everyone else's like..

I just stumbled upon this thread. I have a similar problem and created a thread last night and included a picture.
Did you end up keeping yours or exchanging it?
Thanks!

I exchanged it, but the new phone was not perfect either. I then tried a few galaxy oled phones, like the note 2 and s4, plus a couple of note 3's in the shops, and they all don't have pure whites at lower light levels.
So, I've decided to just keep this, and very used to it. The large screen doesn't help, as viewing angles mean up close never looks perfectly uniform, so it seems a feature of Sammy screens.
The phone is just to awesome for me to get hung up over it. . Most people cannot see these things, and was surprised to see all 5 S4's I got my hands on looked identical, just slightly reduced due to the screen size.

[Q] G2 Screen issues?

I saw an interesting issue with 2 G2 Phones when I went to upgrade today and I wanted to see if others saw the same artifacts.
1.) When holding the screen under bright light, it looks like you can see "through" something and it appears like you can see a pattern of some sort either on the LCD itself or maybe some sort of polarizer. If this was the only thing I noticed it wouldn't have been an issue.
2.) When on a dark or black screen, you can see vertical "stripes" of dotted white lines. This was the deal breaker for me. I purchased the upgrade, they handed it to me and all I could see were these vertical stripes of white dots across the screen.
The other G2 did this as well. Were these a bad batch of G2s? Is this some sort of artifact of the IPS screen? I was coming from a Droid HD which had nothing of the sort but it isn't nearly as high resolution of a screen.
I ended up with a Note 3 because of this. It wasn't my first choice, but there was no way I could look at those stripes for 2 years!
Are any others seeing this artifact on the screen?
Thanks!

It's the digitizer. All G2's are that way I believe. Not a defect. Some phones you can just see it more than others.

OP let me get this straight, you don't like the phone because of the dot matrix you see when the phone is off and in direct sunlight?
You are right I couldn't live with looking at my phone while off for 2 years

It's when the screen is BLACK or DARK while the screen is on. I think whomever suggested the digitizer is probably right.
One of the artifacts didn't really bother me, I was more so fascinated by the pattern than anything else. To see that one the light had to be intense and direct (screen on or off) so very low likelihood of that impacting day to day use.
The artifact that really bothered me was, for lack of a better explanation, the white dots on the screen that looked like backlight bleeding through tiny vertical perforations in the LCD panel. I'm sure that's not actually what it was, but that's what it looked like to me. I'll probably end up with a G2 in addition to the Note, but I wanted to know if the ones I looked at were part of a defective batch or not.
Thanks

Misaligned screen

So I have the edge since the 11th now. And every time I have the feeling that the screen is centered to the right side, I notice it extra with a case. As the area between the bezel and the screen is larger on the left side.
This afternoon I looked with an magnifying glass and indeed saw that this was indeed the situation. It is about 0.1 mm or so but oh so annoying. Luckily I can exchange it, however there will be only phones I stock around the 30th. Keeping mine thill then.
Are there others with the same issue?
The attached version is not my phone, but just an example to explain.
To better understand what i mean I attached a picture. I have the black version but you could see it as the black line on the right side of the phone is thinner than on de left, so the screen is essentially to far to the right..

not the best picture for judging...
But I know what you are talking, I have seen a few devices now and all of them were different in terms of screen quality and alignment!
for me, the worst problem is the uneven contrast (darker sides) on most of the screens. i own 3 devices now and all of them have display flaws. two suffer from a yellow tint when tilting, the other screen has a slightly darker left side... :|

I know. When my S6 comes back from warranty repairs I will try to make a picture. The S5 I have laying around can't focus clearly enough.
Well I hope I won't have a replacement with tint issues or such. Because my screen is, aside of the alignment, pretty perfect. Maybe I'm a bit nitpicky but I think that's justified with these kind of price tags.
I still have till the 30th to get used to it or exchange it. An order for a replacement has been made.

People complain about issues of screen color when tilting the device.. When are u ever tilting the device? U should be looking at it dead on anyways.
Honestly I don't see anything from ur picture, maybe ur just crazy.. If it is a little little misaligned who cares.. It's the curve part anyways..

The picture I used is just to explain what i mean with the black lines on my phone. Imagine that picture with no black line on the right of the phone, so the screen blends in with the white. And a bigger black line on the left.
That's what i have, but my phone is black so i cant put it on a picture to explain it.

I can really only tell in a dark room, but there is ever-so-slight light leakage where the glass meets the metal on the bottom of my S7 Edge. I see the slight leakage on the bottom-left and bottom-right. Doesn't bother me much, maybe a little, but my experience with smartphones is you'll be lucky to find one with absolutely flawless everything including screen alignment. It's often not worth exchanging for a new one, which may have other issues. Plus there's the whole issue of setting the phone up from scratch again. My device seems to be working fine (this is my 5th day with it) so far, so I won't be exchanging it.

After reading this thread I checked mine and its is misaligned like you described. I then went to Samsung and they checked and said that its normal. Now that I see it, its driving me crazy.

Same
Same **** with me. My screen is also misaligned and its driving me nuts with this phone price i dont know what to do about it. I have s7 edge btw same **** all over with the s6edge. I really didnt notice it when using the phone. I noticed it when im checking out the phone looking how pretty it is then when i turned on the screen i noticed that the left side of my screen has a thinner black bezel and when i look on the right it has a little bitty gap.

Dimmer areas of screen and uneven bezels

Hi Everyone,
I bought the Le Pro 3 from Amazon when it was on sale. I've been using it for a few days, and while I love it as a phone, I have some concerns about the display. It appears that the very bottom of the screen (when holding it in portrait mode) is a little bit dimmer than the rest of the screen. I could be imagining it, but it's like the opposite of light bleed (dark light bleed?). Has anyone experienced this? Should I get a replacement unit? The other thing I have noticed is that it appears that the bezel surrounding the screen is a little uneven, meaning that the right bezel appears wider than the left one. The included screen protector might be making it seem like one is larger than the other, but I thought I would ask if anyone else has noticed this too. Thanks!

The brightness on mine is pretty uniform, didn't notice any uneven levels of brightness in any particular region. I suppose it's worth getting a replacement over, might as well since you're within the 30 day return period.

I do not have either of the issues on mine. Maybe you have a defective unit.

Thanks for the replies. I think maybe what I described seemed a little too extreme. When I say a "little dimmer", I mean it looks like the pixels within 1-2 mm of the bottom bezel might be a little darker. It's only sort of apparent on screens with white or grey backgrounds, and would be easy to miss if you weren't looking for it. I'm kind of wondering if I'm just worried too much and this is part of the manufacturing process. Any other thoughts? Thanks!

Dark horizontal lines cause ghosting?

Hey everyone,
I just got an S8 and am curious if a display artifact I'm seeing is normal for AMOLED or not. I tried getting a picture, but it is too faint to pick up clearly. What I'm seeing is that any dark horizontal line on a light background creates a faint ghost of the line extending to the screen's edges. The more black visible, the stronger the ghost. The ghost looks like a light single pixel strip at the top if the line and a slightly dimmer one at the bottom edge.
I see similar artifacts on my old plasma TV. It's like there is a total voltage limit per pixel row. If this is normal (it really is feint) then I don't necessarily care, but if it's a defect I will do an RMA. To replicate, look at an all white image with a few black lines running horizontally, but not all the way to the edge. You should see slight ghosting "finishing" the lines if this isn't just me. Thanks for any insight/help you all can provide.
Edit: just noticed the breadcrumb/forum path right here in XDA (its black underlines) cause the issue, so there's an easier repro.

Hi, could you either detail or link your solution? I'm pretty new and couldn't find it by searching.

Sadly I don't have a solution, just a problem I haven't had a chance to check another S8 to see if the problem is just with my unit, or all units. I did check an S7 Edge, and I couldn't create the problem, but that's still not exactly apples to apples. Will post again if I learn anything, but nothing so far.

Well from your description, I'm pretty sure I have the exact same problem on S8+, and although it is really feint, we've spent so much on these phones, that that little line to me is just infuriating, and I can't stop noticing it. I'd imagine it is actually quite common, but only a minute amount of people will have even noticed it. Will talk to Samsung tomorrow and see what they say about it.

Hi,
is this anything like this: https://forum.xda-developers.com/galaxy-s7/help/ghost-shadow-issue-black-text-white-t3576934 ? I`d also like to know if this "featrure" or bug.
Thanks

i have this problem too do you know of a solution.

Checked on my S8 but could not replicate your issue.

I think this is related to your particular device. It is a hardware issue which you should fix it by either sending your phone to Samsung or to local repair shop.
