GT i950x screen issue, please read - Galaxy S 4 Q&A, Help & Troubleshooting

Ok I picked up my new galaxy s4 today, I've owned all the galaxy s handsets and been pleased with them.
However I noticed some weird screen issue earlier, basically while scrolling dark greys on blacks smudge/smear purple.
A test for this is in settings, on anything grey if you slowly scroll up and down the grey bits go purple.
Does anyone's else phone suffer from this? I've never noticed this on previous phones, but not sure if my handset is faulty or whether it's just how the galaxy s4s are.
I know it sounds odd but I'd really appreciate if someone could test it for me, go to settings where the background is black and there are greyish bars, scroll up and down slowly and tell me if the grey bits have purple smearing/smudging.
Thanks
edit: I've added a picture and drew some arrows to point out what parts go purple/smudge when I scroll, this is just so you know what to look for. It isn't an image that shows my problem, it simply to point out what parts show the issue when I scroll
Thanks
Please report your HW Rev number at this thread and state if you do have teh smearing issue. You can do that by dialing *#12580*369# on your dialpad.

Yes!!! Happens on mine too!!!

Same thing here.

So it's the issue with software right? I hope it's not intentional - given how retarded touchwiz design is, I wouldn't be shocked if it is.
Does it affect it somewhere else? Like videos or something? Or have you tried it in non stock apps? Say download poweramp, put a grey skin and try scrolling?

Thanks a lot for testing it.
Well it must just be the way it is.
I'm certain it didn't do it on the galaxy s3. I wonder if they're using a cheaper screen or something.
I was hoping it might be software related but I watched a youtube video with dark scenes and I could even see the smearing there
The more I think about it the more I'm convinced it's not a software thing, it just doesn't look right, and if you turn the brightness right down it looks even worse. And I mean really bad, honestly try turn the brightness right down and then do it.
I know some people might say "it's not a big deal" as I'm not going to spend all my time scrolling up and down in the settings menu lol, but that's just an easy test to show it. I can see smudging on dark colours in general, I'm really disappointed.

can you make a video?
this is weird

I can't unfortunately as I don't have another phone or camera to video it with.

Mine does this too. It's like the ghosting effects you get on cheap televisions with low refresh rates. Hope it's not a faulty screen, I'd imagine the wait for a replacement will be quite lengthy...

I went to a few stores to test demo units and they all do the same thing.
The s3 doesn't.
I wonder if they're just using a cheaper screen.

It may be the new pixel arrangement in the device. It makes whites look different colours if you look at the phone from an angle.

I too noticed this issue on my new SGS4 today and I´m glad I found a thread with people having the same issue. I also found another thread about the same issue: http://forum.xda-developers.com/showthread.php?t=2253881

I'm gonna guess it's probably due to "adapt display"..try going into display and change to movie mode

Tried it, but no matter which mode I choose, it doesn´t change anything about the problem.

Mine does it too. It's most noticeable for me scrolling through contacts, the grey bars with the letters on seem to shrink then grow with purple edges. Very weird!
UPDATE- Seems like it only happens in TouchWiz. I have Rom Toolbox which has grey bars on dark background and it doesn't happen.

Samsung should fix this fast via software update, this is emberassing for a 700$ phone.

so it's for sure software related?
can anyone make a video so I can see what it's like?

I am pretty sure its the software, for the screen works perfectly when watching a vid of sth white moving on a black background. The smearing only occurs inside the os and apps. I can´t upload a vid of it atm, but I will as soon as I can.
Edit: I made a vid of it with my SGS2, the quality aint that good, but you can see the ghosting on the grey setting bars: /watch?v=iNwCuufJuLM&feature=youtu.be

It does not smear in toolbox or video because the background is not absolutely black. I am pretty shure this is an inherent amoled problem. I guess its either no absolute black level like the s3 or smearing on s4.
It seams the pixels on s4 get turned off completely on black areas of the screen and react slowly when turned on again. On s3 the pixels are never completely turned off to probably avoid this artefact. Thats why s3 blackest black is deep gray.

Pink tint area in the display

I love everything about this phone except...pinky tint at the bottom 1/5 of the screen!
It's especially visible with white background. It seems that the bottom 1/5 part gets very warm when the phone is doing lots of stuff or charging battery and I think that's when the pink tint is really gettung, well pink.
I will probably exchange it once the supply gets better and my local att store gets stocks. Hopefully you guys are not experiencing this.

Thanks guys for the reply. I've got blue one. It's barely visible as my friends couldn't see it at all lol. I have really good eyes, or I have to say "trained eyes " that I do graphic arts stuff everyday. Color accuracy is critical for my job.
My S2 had blueish tint but it was uniform color temperature for the entire screen. I'm currently using app called Screen Adjuster to mitigate the issue but it doesn't solve the problem because of the uneven color temperature. I really think that the heat at the bottom part really changed the tint permanently.
I'm happy that you guys don't have such problem!

I must say it'll be really hard to find the AMOLED screen with no ink bolbs unfortunately.. I went through 3 S2 Syrockets and 1 Playstation Vita. All of them have those blobs or lines of ink that you can see in a dark room with black or gray background. It's really prevalent issue. Personally I gave up about the issue as its only visible in some limited conditions. Sorry but if you don't have any other problems then i dont want you to exchange it with even worse unit...

Oh man I thought samsung noticed this issue with the intl version.. is it possible to use the SG3 without a simcard? I mean can I access the applications / browser using wifi without having a simcard in? I am asking because I ordered one from AT&T and I will unlock it, I don't want to unlock it then send it back if it has issues..

If you want to see if your phone has these blobs, do the following
Go into a pitch black room
Set your phone brightness to auto
Open camera app
Turn off flash
take a picture of pure darkness
View the picture in the gallery, and tap it once open so all the bars and menus go away showing nothing but the image
Inspect the screen up close, you may have to wait 5 minutes for your eyes to adjust
If you don't see those blotches, your eyes suck, didn't let them adjust enough to the dark, or you just wasted your luck on a nice phone rather than a lottery ticket!

How do you know that the blotches you see after this test are not just a camera flaw? Did you send the picture you took on the sg3 to another phone and view it again? If the bloches are there, its a camera flaw. If not, its a screen flaw.
Everysingle amoled screen that I have owned had purple tint. It is more or less common on samoled. Especially noticeable when the brightness turned to low.

Because, i used pinch and zoom while the picture was open and pretty much saw nothing happen on the screen. I could tell from some slight changes in some lighter spots, but the blotches did not move. You can do the same.

Huge screen issue with i9505

I bought an i9505 today. I noticed very bad scrolling artifacts especially on a black background. This can be best seen when scrolling up and down in a menue in the preferences. The white letters on black background smear alot. This effect gets worse when turning brightness down. The responsiveness of the s4 display seem quite bad. The s3, which i also own does a whole lot better in this regard.
Can other S4 owners confirm this problem? Has the octa the same problem? Main reason i bought this phone was the oled display. I am quite dissapointed.

something is definitely wrong with it. exchange it immediately in case something is wrong with the second one.
Mine does it too. Most noticeable scrolling through contacts.
Sent from my GT-I9505 using XDA Premium HD app
So if I am not the only one experiencing this it seems to be an inherent problem of the new amoled. In theory amoled has a very fast response time. Maybe it has to do with the fact that the s4 displays true black i.e. the screen is absolutely black in black areas of the screen. The s3 does not turn the pixels completely off, it has blacker blacks than lcd but no absolute blacks like the s4. I am sure Samsung did this for a reason in th s3, maybe to avoid the problem we are experiencing with the s4. I wonder why none of the reviews reports about this issue.

Mine doesn't smear when scrolling unless you mean if you scroll fast it looks smeared? I put that down to scrolling quicker than my eyes can focus if yours is smearing when moving slowly then I'd swap it!

The effect can be best seen on black background with brightness set to low. For example when scrolling in preferences watch the horizontal grey sepparation lines. When scrolling slowly the almost dissapear on my phone. So maybe one should not call it smearing but there clearly visible moving arifacts on my phone.

I have the same problem. It is annoying in black backgrounds whith grey letters.
I noticed this straight away and started a thread here http://forum.xda-developers.com/showthread.php?t=2252445 (5 pages long already)
My S3 does not suffer with this problem at all.
The screen is a step down apart from the blacks which are much deeper.
My issue: the red subpixels stay on, this is the SGS4 and SGS2 viewing the same 100% black image.
The effect is a bit more dramatic on these pics than real life, to get a proper exposure. The red pixels are only at low intensity, but it's still easily noticeable.
Hi.
I had the same problem with I9505OXAAMDE firmware. I update firmware to I9505OXAAMDM and subpixels are ok. Now my screen is black, but now i have smearing in setup menu and contact.
I hope that in the future fix this problem.

Interesting. You did not have the 'smearing' before? Because I do see some of that also. On i9505-XXUAMDF.

Pink gradient on screen

I'm reviewing the Galaxy S4 and have found an issue with my S4 which I'd like to confirm with other owners.
When looking at a completely white screen and especially on lower brightness settings I have a pink gradient at the bottom part of the screen. Here's a picture: http://i.imgur.com/9jhVEnr.jpg
Normally I'd just swap it, but before doing so and knowing how AMOLED screens usually have weird behaviors I'd like to see if anyone is suffering the same issue. I managed to get a screenshot of a YouTube review which seemed to show the same problem: http://i.imgur.com/DhryGwg.png
Anyone else? Is it normal?

no its not normal better to replace the handset
I got my UK vodafone S4 yesterday, and I've noticed the pink tint at the bottom of my screen as well. It's not as noticeable as the OP's, but noticeable none the less.
I let vodafone know this evening, and they'll send me out a replacement when they have stock back in; I'm happy to keep using the handset until then. If you're within your grace period from an upgrade, and have this problem, I recommend letting the provider know about it!
Again man? Same problem with the S3 really tired of samsung Amoleds problems...every single year there is some gradients, black inks and not black blacks...
Just checked and mine doesn't do it, Send it back.
Actually, after looking at it on my laptop it probably is about the same level as Spybreak's (was viewing on my S4 screen originally :laugh.
You can tell it's not a software thing, because if I move the phone with white webpage displayed into horizontal view, the pink tint is at the right side of the browser (bottom of the phone screen).
I finally replaced mine and the new one has no pink tint. So yeah, looks like its just some faulty units

Damn I have the pink tint at the bottom as well.

This issue plagued my S3 experience (multiple replacements with various degrees of pink and purple gradients). Based on this and other complaints I've been following, I think I may pass on this phone and pick up AMOLED once it has been further developed.
I had slight pink issue on SGS3 (screen bottom and random areas upper) but now I have gradient on top of the display and to go down the tint is dissapearing to about 1/3 of the display. But its not only the white colour which is pinkish on the top third also other colours are shifter from upper side to downside - very annoying I can see it all the time especially on low brightness...
edit: just want to upload some of the photos (only resized, untouched)
I dug up an old SIII pic (not very good, but I have better quality shots somewhere...) and it looks a bit similar to the tint issue with the S4. I wonder what causes this during the manufacturing process?
I have pink gradient at the top of my black s4 too...

[Q] screen banding?

I just noticed horizontal screen banding on the top portion of the screen.
best recogniced in stock background pictures.
also, in phone dial screen and music app, settings, there's very noticable banding right under the blue separating line.
anyone else have this problem?

Yes, I'm having the same issues when I see it on a grey screen. I'm going to end up bringing mine back and try another one. The first one had no banding but it had white lines going through the panel as you were looking at a grey screen. Hopefully I get one that has no issues.
No banding here, post better reproduction steps to get better feedback

i mean, you won't notice any bandings if you don't look really close enough

Banding? Do you mean the little dots in rolls and columns all over the screen? It it's that then that normal.
I went to the lagom link posted above and saw none of the banding or apparent moire pattern of the screens posted above. However, on a white bacground i notice a very subtle banding of discoloration going across the screen horizontally in portrait orientation. It's subtle and a non-issue to me but I guess this might be what the OP is referring to.

Just to note, the moire is an effect from the camera not the screen.

Stupid question, but in the dial screen, could you be mistaking it for the drop shadow of the tabbed navigation bar? I know I did at first. There's a strange amount of separation between the tabs' bar and a very thin drop shadow. Pretty strange graphic design if you ask me.
I dont think so. I do know that there is a shadow right under the blue line.
If you look at the screen close up at night, you will notice some bandings. It is too much and sudden colr shift to be a shadow.

[Q] Is screen discolouration a fault?

Hello,
This is my first topic here, I have just bought a new S4, and the screen seems to have lines in it, when it is on a grey/dark screen, and is discolored on the bottom half.
Anyway, Please could you go into Settings > More > about device > software update. Now if you go in the dark, do you see discoloured patches on the bottom of the screen? (which are lighter than the rest). Please can you tell me which mode your screen is on, as then I can see if I can remove the problem by changing modes.
Also, It seems like when my screen is grey, there are lines all over the bottom half, that are slightly lighter than the rest of the screen.
Would you class this as a fault, as you can only see it in the dark, but I do use my phone in the dark a lot...
Do you think it is worth it to return it?
Also, if it is, do you think I should take it to the Samsung Service Center (I have full warranty, and Knox 0x0) or just return it to the seller
Thanks for any replies, I would be so greatful to anyone who helps
PS. it is not just in settings, it happens in any app that I use...
Well, first of all AMOLED technology isn't perfect and this is well known.
Most of users have a purple /pinkish tint on the bottom of the screen or top.
On mine aswell the bottom part of the screen is more pinkish or something like that, can be seem only on grey backgrounds bot i got used to it and doesn't bother me. Also i noticed when i keep brightness on very low level on white backgrounds like in play store i can see 1 or 2 slightly lighter horizontal lines.
To be honest doesn't bother me, all s4's i checked they all have some screen issues, because is AMOLED.
I have the same. That just something you have to live with.

Really? It doesn't seem very good that it should have lines across it tbh
I am quite disappointed - Does it also seem to have lines that look at bit like burn in, but can't be as the phone is brand new ,and i cant think of any time that i let burn in happen...

If they are visible even on high brightness then is a problem.
So if you can clearly see them on maximum brightness, then you can go and ask for a replacement

Bad news. Seems like these lines and discoluoration also happens on full brightness. Looks like I need a repair. I'll try and post some photos tomorrow...
Edit: I bought it on eBay. Should I open a case, or should I take it to a Samsung service Centre as there is one close to Me?
I have the same lines, mostly visible on gray backgrounds. I can really see it on the weatherbug load screen. The one my eye sees the most is about 25% up the screen from the bottom, but when I stare for a while I can see a lot more. From what I've read, this is normal.
I dont get a full equal black screen either.Its like light is trying to get through in the bottom half of screen.Its more noticeable on lower brightness.
Never noticed it before....

Im sorry for tell ya but i think u have LCD screen troubles, like HERE
Every S4 has grey bands across the screen. The worst is the one about 25% up from bottom.
It's just a flaw of AMOLED screen

But this was not the case for S3 screen when I had it. So it is the new panels that have this problem.

You're right, the S3 screen was fine.
The new panels in the S4 are crap ( in my opinion)
Only advantage is 1080p, which for a phone is pointless (again, my opinion)

Hate to be the bearer of bad news, but I have absolutely no strange lines or differences in colour on any given background.
I only got mine a week ago though.
I'm sure you will mate, or you just haven't noticed it yet
I've had 7 different S4s and EVERY SINGLE ONE had banding in greys.

You are right I also had another s4 and the same thing. Probably if you go to the store and try the phones there all of them will have this. At first look with high brightness on it is not obvious but after looking carefully you will notice it.
