Screen streaking/unevenness?

I haven't seen this mentioned anywhere else. Does your ET show (mostly) vertical streaking/unevenness when displaying a solid, light color? Is this something related to AMOLED, or is my ET defective?
Edit: I just realized this is dependent on screen brightness...the streaks are only apparent at the lowest brightnesses.
Thanks.

Screenshots would help others see what you're referring to.

I get this when my screen goes off and on

I have to mention that the first one i had, was like this, but it showed like a dark spot in the center of the screen, btw screenshots wouldn't show this problem because is actually the hardware" Screen" In this case.
So i went ahead and brought it to the Sprint Store where i bought it from, and asked for a replacement due to the Screen hardware defect, they kept *****ing at me telling me, that they have to keep it for a whole day, to do "Tests" Im like... well its a hardware issue and i have taken the phone and hardreset it, making the phone as if just out of the box, and showed them the problem again"btw the phone comes with a Gray and Green pure colored background images that you can show to them, that it isn't an Image that you had Altered" , and they can see that it is the screen, and its what i showed to them, and thats when i got my replacement, When i got this one, i saw it again, and it had a white spot... also had various streaks coming from the Top of the screen, went int he second day and got me another replacement, but before i left the store, i stayed about 30 minutes in there, testing the phone out, and downloading all the apps that i had in the phone before. Also Good way to notice this problems( defects ) is dimming the screen all the way, and changing the background to gray, which is a default wallpaper.
This screen didn't have any of the defects that previous ones had, so im a happy camper .
So now what i'd recomend if you can, is replacing/exchanging the phone until you get one with a decent screen.

I get this too when my brightness is turned down. It's most visible on grays. Like the background of the market. It only appears when the brightness is turned down low. There is also this app in the market called "screen test" which cycles through different solid and colored backgrounds. that if you did take it in you could show them that. This issue doesnt really bother me but I have TEP plus there is a one year manufactures warranty so if it gets worse I'm not worried about it.

I finally got around to taking a quick set of comparison pictures. Sorry for the poor quality, I took them quickly with my phone. I also tried to purposely take them out of focus, so moire patterns from the actual pixel grid wouldn't confuse things. I have a feeling this is how all *LED based displays are.
I use the app "Colors" to quickly get a solid patch of color. I encourage a few people to download it, and browse through a few colors (grayish or dark tones - light or bright colors aren't affected as much) and see if they have it. "Grr-ey", "Mighty Slate", "Kind Giant" are good ones to test with.
Things are much more noticeable when the brightness is set low.

You may be right my screen has the same effect :-(

[Q] Would this qualify as defective?

My screen shows banding on screens with gradients, like the call log screen, or screens with certain colors, like when I'm playing wordfeud. Even when I'm browsing the white background has faint horizontal and vertical lines.
All of this is only visible when on the lowest brightness setting. So when I'm browsing in bed at night etc it's really annoying.
I went to the (3) store here in denmark, but because it was a well lit room, the problem was barely visible and they said they'd have to send it in for "assesment", and best if i could come back in January and send it in (for 2-3 weeks). I'm just afraid they'll just return it with "problem not found"
I DID manage to report the problem to them on the 14th day after i bought it, their own DOA limit, but I've got a feeling I'm going to get screwed. Especially because the in store phone ALSO seemed to show the same color banding on the call log background.
I've tried taking some pictures that maximize the problem here: http://imgur.com/a/CbKYi#9
Are you guys seeing the same thing on any of your devices?
I love the phone to death otherwise, but it's like a scratch on a brand new car, it's annoying me a LOT.

unfortunately, that's just how they all are. has to do with the display type. both of the nexus' i've had were the same way, as was the display unit in my local verizon store.

You aren't seeing "banding" in the traditional screwed up screen sense, you're seeing the back of the display. I think it's just part of being SAMOLED and Pentile. I never noticed it until I started reading all the threads about people complaining over "banding" (and I don't think you're complaining LOL ).
Bump it up from the dimmest setting just a bit and most of it will go away. Our dimmest setting is REALLY good, at least compared to my old SGS. I also like how are screens don't have that SGS SAMOLED blue tint to them.

go to that call log screen again and press vol down + power. then look at the screen shot on the computer.
it looks the same
the background is ment to look like that

All 4 phones and 7 models that I've gotten to use from Samsung have this problem.
SAMOLED just isn't very good yet.

happy to hear my phone is not defective, but then again im very disappointed that this is a quality issue with the phone.
I read tons off aritcles discussing the difference between Super AMOLED and Super AMOLED plus (pentile and RGB) and this forum probably did the best job of explaining it
now is this also the reason why whites arent really white while having hte phone in auto brighntess? is the screen is dim, my "people" app is not white, actually far from it. but when the brightness is maxed out it looks magnificent

I was disappointed by the screen quality at first too, but the more I use the phone the less I notice it. I've even started to really like other aspects of the display that were lacking in other phones with a "clean" screen. Colors are much more vibrant for one, this is very visible when watching videos on the phone when I'm at the gym.

[Q] Should i take it for warranty? or is it normal?

hey there guys. am having multiple issues in a 1 week old Note 2 which i noticed very recently.
first issue being , strange fade outs near home button, (tried cleaning screen with everything from water to specs lens cleaner,it's a permanent thing..... and looks like it is under the glass )

}
Second issue is non-aligned fade outs on front cam and sensor
third issue is , there are few pixels on left side of screen that do not blend in with other black pixels around them(except for videos where color is similar to pull down menu on home screen).it doesn't move either.it's in a permanent location. it can't be seen under proper light and only appear on more or less lowest screen light setting with ambient light off.this issue however doesn't occur with any other color of video,they blend in perfectly.it's similar to note 1's black crush issue,but on a specific spot
sorry but this is the best pic my cam could get. you have to look very carefully
Last issue is, S pen doesn't work on lower right side of the screen. like on the very end in the corner. it works fine in other 3 corners.
I know i sound extremely paranoid.... but i love this device so much ! would love perfection. should i take it to service center? will be pretty darn hard to explain the issues though. and can i expect a replacement ? on the side note, i got it from India and no carrier.
Thank you for reading

Hey,
I dont have ANY sort of fade outs anywhere. You should definitely have it checked. As for the S pen....even mine doesnt work all the way down to the end on the lower right but does go to the end of corners of remaining 3.

First question, do you have a screen protector on? If you do that will explain everything.
Looks like a misaligned screen protector to me.
Sent from my GT-N7100 using Tapatalk 2

guess it's warranty time then
and no ... no screen guard is on.it's whitish cuz of moisture and oily hands,can't help it in India's climate and tired of wiping the screen every hour. but those fade outs are permanent thing.
i do plan on getting screen guards soon after taking it for warranty though.

Possible screen issue with brand-new Galaxy S4 Mini

I recently (as in yesterday) got a brand new S4 Mini SGH-i257m. It was completely unopened, still sealed. Unfortunately, I may have some sort of issue with the screen .. but I'm not entirely sure. When I'm looking at a gray or dark gray screen, there appears to be a lot of discoloration and ditherting.
It's most noticeable when looking at a solid gray colored screen, such as the background in SD Maid. It doesn't look like a solid gray at all. Even pure white screens have a "dirty", dithered tinge to it. I know it's not burn-in. And I know I don't have a dirt and grease covered screen as I just got it yesterday. Even after wiping it down with a microfibre cloth, the effect is still there.
Is this normal? Do all S4 mini screens have this effect? Should I just get used to it (I probably can't unfortunately and will have to sell it), or try and get it repaired?

Yes it's normal for amoled screens...first i thought the same thing...?if you do a color test...you don't see them...you can see them only with grey colors
P.s sorry for my English

Whites can look yellow-ish. And as I've never used anything with a better screen I couldn't compare, but to me my screen doesn't seem as bad as yours. Everything is clear enough, no grease mark looking screen... Maybe watch a couple of YouTube videos of the s4 mini to compare yours. But it doesn't sound right to me... It may not be a 720p or 1080p screen but it's still clear enough.

Help!!! S4 mini screen white
Hi,
I have a Samsung galaxy s4 mini. it was working completely fine and all of a suddenly the screen just went white. I can interact with the screen and I can hear when I'm pressing things but the screen just stays white. I've tried taking the battery out and restarting it. after the start up logo appears the screen just turns white. I can get into download mode and I can see the screen.
'
what could be the issue.

It's normal, it's due to the non-standard subpixel layout:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}

That's really unfortunate, as I really like everything about the S4 mini, except for the way solid colors look like a dithered mess. Maybe I'll just get used to it ..

Follow-up for anyone who cares .. I got my hands on another S4 Mini, and the problem is still present on this one, but much less noticeable. It seems the new one I got has an especially bad problem with this issue. I will see if I can get it replaced with Samsung ..

Yellowish tint on screen?

Might be being paranoid due to 2 XL screen issues but has anyone notice a yellowish tint to the screen? It almost seems like off axis is more pure white and looking directly on is a warmer white if that makes sense. Might try to take pics but not sure I can capture it.

I haven't noticed any hardware problems with the display yet, although I do have black clipping in movies.

Instead of starting a new thread I decided to post my issue here because it's screen related. I don't have any yellow hue with my screen. I unfortunately have a pinkish hue on the right side of my phone. I saw it immediately after powering up for the first time. Kinda reminds me of the S8+ fiasco. It's just in the right side and starts about the middle of the screen and heads up to the top. I called Google and they took my issue very seriously. They wanted pictures and it's a very hard thing to capture with a video or pic but they said they could see it in one of the pics I sent. They have me play some white screen YouTube video and wanted a picture while that was playing. Anyways, they took my info about the issue to some higher ups and called me back about an hour and a half later. The person I dealt with was nice but a bit pushy with getting pic results. He was concerned about some widespread issue because the phone was just released. So he said that these panels have some color shifting (ok? Already went over that) but offered to send out a new replacement. That is me basically buying another and not getting charged unless my original phone isn't returned on time. I'm very disappointed with the screen having this issue. I went through the whole blue screen last year. I had to get two replacements until I received a "good one." Anyone else having screen issues with color?
Sorry to hear about your yellowish screen issue. If you aren't happy with it I'd return it. There are a few friends of mine that have great screens

Here is what I'm noticing. Maybe that's just the way it is and it's something I've never noticed before. The funny thing is I have a Xs Max and the Pixel looks better. Interestingly enough the second picture (pure white) looks similar to the Xs max if true tone is turned off.

My display is great. Beautiful. I'm grateful too because I went through 7 2 XL's before I found one with a display I could deal with.

Adaptive brightness, if on, will turn the screen yellowish in low light conditions.
Otherwise, I didn't notice anything since I received the phone today. I've been using it all day.

Nope, mine has been fantastic. Looks great.

Going to have to go check other devices in store. Can't tell if what I'm seeing is normal without another unit to compare.

No matter what phone you get an OLED screen is a lottery to how even the whites are or the degree of hues

+1 I've seen some "comparisons" saying the 3 was warmer than the 3XL they saw. I'm opposite here. Received a 3 before launch day. Nice, cool screen (which is my preference). Phone felt way too small for me so I picked up a 3XL at Best Buy yesterday. Quite a bit warmer than the 3. Returning that one today haha.

Haha If it's noticeable straight away and takes away the enjoyment of the screen then a swap is the best way. I've had devices from Samsung, Huawei, OnePlus, Google etc and I've had bad tints or uneven whites on them all..so part of the oled game

Do you have any updates on this? Did you try to contact Google?
