I've had my N7 for a week and a half now, and there is only one flaw: I have a 1.5cm dark band down the right side of the screen. It's only really noticeable on white or solid pale colours, so for videos and games it's fine but it's a little distracting when reading black on white.
I have only the slightest amount of backlight bleeding round the edges, even under extreme conditions (ie. full brightness in dark room,) no dead pixels, no ghosting, no issue with washed out colour. So I'm just wondering if it's worth getting a return or just waiting to see if it evens out a bit.
I haven't found any mention of similar issues on the forum, so I'd like to ask how people are finding the uniformity of the display?
same problem
I have the same defect.
How did you resolve? Did you get a replacement?

I think I might have the same problem. But with mine it only shows after having the screen off for a while, and it slowly fades to normal after the screen warms up.
So far what I have done is have all dark themes so I dont see it anymore. Have tried to refit the cables inside and using pixel fixer apps, none had worked.
Sent from my Nexus 7
So, today at night I noticed that when I'm in the camera in dark areas, or in Spotify with a dark background. I noticed that the screen in the middle from the notch till the chin has a lighter colour than the edges. The width of it is about half the screen centred in the middle. It's kinda like how Zack (jerryrigeverything) puts a lighter to the screen and the pixels turn white, but it's not that extreme. It's only noticeable in low brightness, and dark backgrounds, not black. The most noticeable was in video on the front camera. The "stain" has a lighter blueish tone to it.
I'll leave some pictures for you to test them. I know that when I checked on my phone again with light, the stain wasn't there. Test them in a low lit area, and lower the brightness almost to the lowest setting.
The second pic is the front camera (the most noticeable in person). On xda, I find Spotify to the most noticeable.
Maybe I'm blind but for me everything is ok. Maybe you have DC dimming on. Sometimes screen may look weird in dark areas with that option turned on.
Yes this must be due to DC dimming, called anti-flicker in the settings, shut that off and see if it gets better. If you want to show us how it looks you will have to take a photo of the screen with another camera since it doesn't show in a screenshot. That picture is captured before it is sent to the display. The "anti-flicker" setting is known to produce distortion at low light conditions.

so ive tested it on and off. With dc on, it made worse. So i left it off. The picture ive taken (which was the best i could take) shows a green hue highlighted with the circle. I dont think its the screen protector as it only shows up on low brightness and dark colours, especially grey. Any ideas?
P.s. It looks a bit worse in person than in the pic.
Oh, now I see but I couldn't reproduce it on my Mi9, no matter what brightness or with DC dimming on/off. I'm afraid it may be some screen issue.
That's a dark gray uniformity issue, it's fairly standard on oleds, especially low end ones such as this one. On mine the green tint is most prominent on the top right corner and gradually lessens to the opposite corner. There might be more uniform ones out there but they're like what, 1 in 10 units? If you say yours actually looks worse than in the photo you might have one of the worse ones, but if you can exchange this unit don't expect to get one that's significantly better. To get one that's surely better you have to go for the more expensive ones because those use newer generation panels so the uniformity issues only show at the darkest of grays and and the brighter parts will actually be brighter white which is correct, not green as is the case with the mi 9 panel(pre 2017 panel, samsung stopped having this issue on the s8).

Since I never saw this on a Mi9, not mine or any other, I don't think this is true in the case of the Samsung display used by Xiaomi on the Mi9.
The topic starter should contact the seller and get a replacement.

That’s entirely up to you! Can you disregard the distortion you will be ok, but if you find yourself constantly noticing it and being annoyed by it then it will be well worth the hassle I would guess. But only you know what’s right!
Have this on mine, ordered another one in hopes that I can get a better one but it was slightly worse, checked the one they had in a newly opened mi store, that one had it as well to a similar degree. Saying this doesn't happen on the mi 9 is bollocks, all of them have it to some extent, it's a question of how much you're willing to tolerate.
The best thing you can do IMO when you're in a pickle about returning something is do what I said I did: order another one but keep the first one around, compare and just keep the one you like more. That way you won't feel bad about returning the first one and being stuck with the 2nd or just being stuck with the 1st if you don't return at all. Obviously it all depends if you can fit all this into however much time you've got left to return, I was lucky to have 30 days.

Hi All,
I also experience the touch screen issue on my Galaxy S20 FE.
I have created a short video on how to check and reproduce it: Galaxy S20FE touch screen issue - testing and reproducing
Please share your comments if you also experience it.
Did that experiment and i think my device is "ghost touch free".

Yes, if you don't experience this, you unit is issue-free. I have also asked others to test, they have no issue at all.
This is why I think that *might* be a hardware/production issue.

Yes, that's what it would seem to suggest - and it's discouraging, I was really hoping this was a software issue. Would the 120 Hz refresh be a factor in this? That is, do you get the same result at 60 Hz?

Nothing. Either under charging or not, either 60Hz or 120Hz, no matter if Touch Sensitivity is set to low or high, it happens.
But as it doesn't happen for everyone with the same software, it tends to be a hardware issue or a production defect.

Thanks for the feedback. It seems not all users are having this issue. If you cannot reproduce the issue following the video instructions, then you are touch error-free. But then, it shows that it is not a general issue, but some manufacturing defect. For the red tint, I have seen your other post, I also have a barely visible greenish one, around where the camera is, and around the bottom 1/3 mark. But as it was stated, it is somewhat "normal".

Good question. I spoke with Samsung Support and they wanted me to visit the Service Center. I told them that I will not spend that much time on it, this phone is too expensive for having this kind of support. I will just return it and ask for a refund, then wait 1-2 months if the problem is solved.
I was just thinking yesterday...
This phone has Gorilla Glass 3 on the display, which is a way different structure than current GG6 (or GG4). GG3 is much thicker and more acts like a glass (breaks easier). Since GG4, newer Gorilla Glasses are more flexible, thinner, and more durable, too.
What if Samsung has just put a thick glass on top of a modern digitizer (touch panel) which was designed for a different structure and much thinner glass layer, and this causes the touch problems?

I notice it under normal circumstances like browsing, while straight looking at it, when the page background is like pale yellow/orange. It is only a bit visible, but when you read text and scroll, it is disturbing that the greenish tint remains on the screen. But honestly, this is not that bad. On a white background, I don't even notice it.
When I look from a bottom angle and moving the phone's angle, the tint bars move as well.

You mean are referring to the green tint correct? Are you saying that you have no reddish/pink tint at all on your phone?
I notice it very clearly when looking at it at angle or even normal position. And I can see it move when I move the phone to different positions.
the XDA review has the same issue actually (nothing on the touchscreen): https://www.xda-developers.com/samsung-galaxy-s20-fe-review/
"The viewing angles, though, are disappointing because the display still features visible angular color shifting to blue as well as a rainbow out interference effect at extreme angles. Newer Samsung OLED panels have eliminated the rainbow out interference effect, and also reduced off-axis color shifting by a significant amount. The Galaxy S20+’s viewing angles, for example, are much better because the color shifting is much lower. Strangely, even the cheaper Galaxy M51 (review) doesn’t feature the interference effect issue (that is likely caused by the polarizer)."

EU. I bought the phone in the official German Samsung webshop. If I would be out of the return period, I would of course take it to the Service Center even with the red tint, but this way, I will just return it.

True, I have no reddish tint, I have some greenish one When looking straight at the phone, it is around the opposite side of the camera, and about a thumb tall. But really, not that visible, I just see it because I know it is there
I read the quoted article. This can also easily happen because of Gorilla Glass 3, maybe it has different inner reflection that causes these bands.

That sounds reasonable...however, what about all the phones using GG5, 6, or above that have a tempered glass screen protector on them, which would certainly make the glass atop the digitizer much thicker, and that do NOT have any touch issues? It seems to me that the thickness of the glass...up to a reasonable measure that I do not know what it may be...is not the issue here because my S20 FE does not have the touch issues. But mine does always turn on in my pocket. So it seems as if the proximity sensor is faulty. I wonder if this "bug" is somehow related to the touch issues. Though they appear to be different problems...they are related to how the screen works. Clearly something is wrong and I am not sure that any of it can be fixed with software. SMH

You are right, I also thought of it, but not only the thickness, but also the material structure can cause problems like transferring more static electricity to the digitizer that cause ghost touches. And the glass screen protector is on top of the screen which is far enough in distance from the digitizer. I can also imagine that combining this digitizer with GG3 would require less manufacturing tolerance than they used, and that causes just too much defective units. Just guessing...
But as you also stated, problems are mostly with the screen and touch panel. Ghost touches, incorrect finger recognition causing jerks, pocket wakeup, reddish/greenish tint on the screen. And +1: not all users have this problem.
If this would be a software-related issue, all models would be affected more or less. If some units are fine, some are wrong, with the exact same software, then it should be a hardware-related problem. Question: do they used different brand of digitizers for different units, or there is just a huge ratio of defective units coming out of the factory because they had to put as many units on sale as they could because Pixel 5 and iPhone 12 has arrived and they wanted to catch a lot of customers? Just guessing, again...

If watching from bottom angle, I see the bands, but in straight view, I only see some greenish tint. It is not very disturbing for me. I mean, I have a LED TV, which has some of these typical IPS clouding effect on the screen edges. 99% of the time, it is not visible because the content is bright. But when watching a movie that has a night scene and there is no ambient light in the room, it is awful. But in general, I like the TV

Interesting, thank you for the response. I see the red tint straight on and at angles too, so maybe we have a similar issue but a different color?
I also have a LG OLED, which can look quite bad in some very dark scenes because of banding.

That might be the case! Different color, but the same tint / band.
In low or dark ambient light the screen seems to have a pinkish or red tint when viewing the panel to the side. I don't remember seeing this on the N20U. Anyone else?
Very common in phones in the past year. Either green or red tint in low light. My 8pro has a green tint at low light levels and there's many reports from many makes and models of phones of this.
So probably normal. Just didn't seem to be a bright or white as the Note 20U.

Im not sure it's "normal" more that there's something going on with the latest Samsung panels. Is the N20U 120hz? I think it's something to do with the refresh rates because OLED TVs suffer from "raised blacks" at 120hz. I think high refresh rates mess up gamma levels in OLED.
Yes the Note was 120 but not qhd
Do you have a screen protector installed? it could make this tints worse, also don't forget this issue is only with "cheaper" displays, i don't think Samsung uses that kind of "cheaper" displays in flagships!
I did remove the factory protector and it did seem to make the panel slightly brighter. The pink only shows up in low ambient light with the screen at100% and really only then if viewing it at an angle. It's slight but haven't seen this on the Note 10, Note 20 or s20.
Are you using 120hz? On the note 20 ultra this cause slight colour shifts...
Yes 120 and qhd although not at the same time on the Note.
I don't see pink tint in my s21 ultra.
Exynos version
How does the white balance in a dark room with the screen cranked up seem? Warm or cool? It's not as bright as the Note so maybe that's what I'm picking up on.

This is the reason... Sadly every device with 120hz has either red or green tint issue :/
Well that is unfortunate then.
Yes to pink tint! Exynos
no pink for me USA model snapdragon
Same Pink tint problem. Exynos. Don’t need 100% brightness. Just at white screen and slightly tilt it. And pink tint appear.
Same as 13:20s in this video
So it sounds like it might be normal for these panels then and the 120 hz as mentioned above
I just turned the white balance one notch to cool and it seems to eliminate the pink and then into the advanced and then the red down a bit
