[Q] New S4 - Screen issue - Galaxy S 4 Q&A, Help & Troubleshooting

Hi,
Just got my i9505 and noticed some banding on one third of the screen (top). Specially in low light environment and with a white/light gray backround. A pure white image shows like a gradient.
Is this normal? Should I ask for an exchange?
Edit: Uploaded photo

While I don't have that phone I would say that it's not normal. Take it in.

Are you having this issue? Purple smearing? All the S4s have this issue.

Yes I had read that issue,have it too. Didn't know about the update though.
The main problem is this kind of gradient I have in the amoled screen. It's slightly perceptible but once you see it, can't stop looking at it.

Definitely not normal. Some devices do have that gradient with gray backgrounds (including mine), but it's much less noticeable than yours.
Take it back!

Display has a pink tint!!

Please help! I just bought the Bell galaxy s 2 today and realised that in low brightness settings screen has a pink tint.
Does anyone have this issue? Its more visible in grey colors. When i compare with my galaxy s, galaxy s' whites are true white and galaxy s 2's white are pinkish tint on it. When the brihhtness is at %100 its not that visible but once u set it %0 it becomes pinkish.
Is it what it suppose to be or its defective?
Note: yes i played with background effect but it didnt help. I am running KG2.
Edit: I compared with galaxy s again and if I make the brightness %100 on galaxy s 2 both screens almost identical (although SGS2 still has little warm whites) but at %0 brightness when I pull down the notification screen sgs2 has literally pink hue
Why not anyone comment on this? 100 something views and no comments?
U guys all have sgs2. pls at least share your phone's display colors so I can know if something is wrong with mine.
Yep got it to and also pink on camera also mine going back to Amazon tomorrow had two in a week with same problem Ive got one ordered from another retailer ... but I think its a inherent fault

Are you saying your whole screen looks rather pinkish ? I've seen couple of devices that were pretty much reddish when showing white, but i think that's not normal. You should replace it.

Yes whole screen has a reddish tint. Especially grey colors. Instead of grey it displays reddish. If i compare Gmail app with Sgs side by side, my screen has ridiculously pink color.
I wonder if its a software issue or hardware? Cuz I remember in sgs hardcore's kernel he made an.option to change the colors.
This is my second sgs2. First one had a dead pixel. So I didnt wanna go right away and change it. I wanted to ask yours.
More input will appreciated.
I uploaded a pic SGS and SGS2 side by side displaying Grey Graident Colors. what do you think?
If your phone looks like the one on the right, get it replaced. No rom/firmware will make it look good.

I'd take the lack or response to mean that it's not a problem experienced by many people. If your read the threads talking about the display, you'll see there's wide variations in color temperature. Cool/blue seems to be normal while there are reports of phones leaning toward warm/yellow. Pink hasn't been reported a lot so I'd exchange the phone.

I am also from India and I dont have any such problem with my sgs2...
My girlfriend and I have the same german sgs2 (dbt) and mine has a bit of a greenish tint whereas hers had a but if a reddish tint. You can't notice it when using the phones alone but when you put them side by side you can notice it a little bit, but really not that much. Seems to be an AMOLED thing. Maybe I'll manage to take a photo for you.

Thanks a lot for that image. I have been wondering what people were talking about when they mentioned pinkish screen...
Luckily I don't seem to have that problem. It seems like there are a few defective screens out there.
perhaps supercurio will have a voodoo colour fix with the sgs2 whenever he releases it. It fixed the tinge on the original sgs. Look it up if u are unfamiliar with it
I changed the phone today and got a new one. Its better now and significany less pink color.
Also I discovered something that the pink tint is only visible when u look at the screen 90 degrees. If u tilt the phone a little (5-10 degrees) to left-right or up-down and view like that the color turns normal (like my year old sgs).
It made me realise that this is a screen coating issue (maybe coating causes polarisation). So do u think this will go away with the time of use?
When I turn off the screen and check it under light by tilting I can see a little purple glare.
What do u think?

Does your screen hue change from magenta to green?

I've noticed whenever the keyboard is toggled on or off the greys change their hue.
It's subtle but most noticeable when on low brightness and in a fairly dim room.
I noticed it the most in the Playstore when you click the search bar at the top it brings up a list of resent searches, now hit the back button to make the keyboard disappear and the whole screen changes hue, click search bar again and it changes back when keyboard reappears.
Can someone else please test this?
I'm just trying to work out if my screen is defective or if it is an 'issue' with all S4s.
Thank you
Yeah, mine changes hue a little as well. Strangely I had my screens changed four times but this is the first time I noticed it.

Thank you for checking. It is actually quite noticeable when you're in a dark room, it's really bugging me!
This is my third handset, the first had a serious pink tint on the bottom of the screen and the second had a light horizontal band across screen when viewing white or grey images.
This one also has 'banding' on light coloured or grey images but not half as bad as my second!
I have the banding issue too! But my problem was mostly dead pixels and stuff. My current set has one tiny spec of dust under the screen but they told me I couldn't change it anymore.
It's a shame that you just can't seem to get a perfect AMOLED screen. There's always something

Screen smearing when scrolling through menu...?

Anyone else experiencing this??? It looks weird almost like it's a lag or something but it's not. It's like a legit pinkish type tint when scrolling. Am I gonna have to return my device ALREADY?!?! I literally just bought it 4 hrs ago -___-
EDIT: OK so I'm informed this is called "smearing" and that's the perfect word to describe it. Only happens in the settings, looks like the words are lagging behind my scroll and catch up lol. Is there a work around for it or something? Even though there shouldn't have to be but that'd be nice i I didn't hafta go through the process again of getting a new phone a day after I got this lol.
If you mean in the settings, that's normal. That's screen smearing/ghosting. Explanation is in this video here http://youtu.be/C_APG3kLiYs around 13:30.
The pink tint issue is another thing.

Yes, it only appears in the settings that it "smears" as you call it, yeah actually smearing is a way better word to describe it, not a different tint. Is it on every S4 that this is happening, or is it a defect in only a small % of S4's? And is there a workaround for it?
Also, what is the "pink tint issue"?
Thanks!

It's the software. I've heard of the pink tint but haven't read up on it. I heard the smashing affect is cleared up on the new update we might get but that could just be talk.

Yes. Every S4. There is a work around. But it takes away from the screen by messing with the gamma. The pink tint issue is when part of your screen is darker than the other. Like my S4 is dark at the bottom and gets lighter as it goes up like a gradient. Like this picture http://i.imgur.com/9jhVEnr.jpg or this http://i.imgur.com/DhryGwg.png
It's more noticeable on grey screens.

Actually now that I see it. I notice it on every settings menu with a dark interface. Doesn't happen on lighter screens, only the black screens really.

The smearing will only happen in dark settings yes. It has to do with unused pixels. Like the video I posted before explains. If you don't have a pink gradient issue then you're all good. If it does I'd get it exchanged asap before you're stuck with it like me.

Look at a solid dark grey background. If its darker on one side that's bad. I noticed mine when I was texting everytime I pulled the keyboard up the text bubbles changed colors a bit.

When I open a black background it's not so clear!

It only shows in stock apps with black background because it was designed that way. But if you open a pure black image you won't see these textures.

Hi, this is called screen blotching and is common on AMOLED screens. It can be seen here

****, It;s really annoying me! I'll contact the place where I bought the money to see if I can get a replacement. " Even without Warranty I've 14 days to replace it if had any Manufacturing Defect " .. :/ My mobile status is Custom but it worth a try anyway.
No, S4 is different. On latest firmware, It will turn off pixels completely on truely black color.
So that blotch will never be seen even if it is actually there. The amoled before S4 does not turn off pixels on truely black color, that's why only S4 has smearing problem.

Well even if you get a replacement it will do the same thing. Not a defect, just a downside to the super amoled screen.

Just relax. Your hardware is not defected. Just do on thing. Google jet black wallpaper. Download it and save in gallery. Open it in full screen in complete darkness. Your screen should look totally black like it's turned off.

-.- the same photo I open on galaxy S III doesn't have the blotching on it!

Top half of screen is dark

Hi all
I just bought a S4, and I noticed I had the purple smearing issue. I have now updated to the latest BMF8 rom which really solved the problem. But now I notice one issue, when I display a pure white background or a Grey background, I notice the top half of the screen is darker (pink tint) than the lower part which id yellowish...
it is the same no matter what screen brightness I set.. the top half is darker than the bottom... is anyone having this issue? my S3 does not have this problem...

I have updated the first post with screen shots. I dont know if you can see it but as I said, the whole top half is darker thsn the lower half.
I have just been to the Samsung kiosk in my home town... showed the phone to one of the reps and he confirmed the screen was darker on the top half... hopefully this gets changed tomorrow when I go to the phone shop...

I'm hoping Samsung comes out with a fix for the pink tint.
I seem to recall that the s2 had issues with yellow tint on the left side and Samsung came out with a kernel update that fixed it.

I had same problem what @nm8 had. I sent my phone to warranty but only thing they did was a software update (what I did three times before sending it to there). Of course that didn't help, after I got my phone back it was even worse. I wrote petition to the shop from where I bought phone. Yesterday they announced to me that Samsung after-sales service will buy my phone back.
Right now I don't know that is this phone worth of buying again (would buy 32 GB version now). It's one of the most expensive phones in the market so I would like to get nearly perfect screen...
