Well if it isnt, this would be a serious problem for Samsung, since they would have to exchange every Galaxy S4 which has been sold. This would be a financial and reputational catastrophe for them.
[Galaxy S 4 Q&A, Help & Troubleshooting] AVF Jay:
This is not a software issue, it's the screen.

It looks even worse when the brightness is down too.
[Galaxy S 4 Q&A, Help & Troubleshooting] simacca:
No purple haze on the Note 2 either.
[Galaxy S 4 Q&A, Help & Troubleshooting] Al Gore:
Letters smear for me on low brightness.
[Galaxy S 4 Q&A, Help & Troubleshooting] tuxonhtc:
Oh dear, I hope its software :( If it's something like the black crush issue, it could be easily fixed, but if it's something that has to do with the display, oh well.

This is it right?
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
Yes, I uploaded this to show what it looks like.
[Galaxy S 4 Q&A, Help & Troubleshooting] PLUG313:
I can't see it ._.
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
You have to look at the grey setting bars, they get violet on their top and bottom when scrolling through the settings.
[Galaxy S 4 Q&A, Help & Troubleshooting] ste1164:
That is really weird. Took me a few seconds to notice it.
[Galaxy S 4 Q&A, Help & Troubleshooting] PLUG313:
I feel blind.

I hope it's not too bad though, as I wouldn't be happy with any other phone that's out right now, and I really need a phone
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
Thats exactly my problem too, I just cant imagine buying another phone, since there isnt any that matches the features of the galaxy s4.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
This problem is really bugging me now. It's all I notice!

I'm starting to think that it is just something that we are going to have to put up with due to the new AMOLED technology and true blacks.

When is Samsung going to release a AMOLED screen without issues!!

First the were colour tints, then inkspots and now purple streaks!

FML
[Galaxy S 4 Q&A, Help & Troubleshooting] PLUG313:
does EVERYONE have this? or is it just some people?

because if it were everyone, many more people would be complaining...

maybe you can get a replacement .-.
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
That's what I want to know.

Is it on both the i9500 and i9505?

Maybe every S4 has the problem but some users simply don't see it.

I just rang Samsung NZ and they told me it sounds like a hardware fault and I should take it back for replacement/refund.

I'm pretty sure that every S4 has the issue and it is simply just the way the new AMOLED screen works, which is a shame.
[Galaxy S 4 Q&A, Help & Troubleshooting] DanteSSS333:
Its present on every Galaxy S4 (9500 and 9505). Maybe they used the white theme for the settings during the presentation in order to hide this issue, which implies that they knew about it before the launche....
[Galaxy S 4 Q&A, Help & Troubleshooting] Mittaa:
Maybe just another conspiracy theory ... but on the other hand I too really was wondering why they used white theme :eek:

They use to be proud of Amoled pure black LOL
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
That's exactly what I was thinking, obviously used the white theme for a reason.

So what now........I guess you could call this a defective screen.

Unless everyone returns their S4s and doesn't buy another one until they replace the screens there's not a lot we can do.

Anandtech is still drawing Samsung Galaxy S4 review part 2, isn't it? If this highly respected web page analyses and echoes this issue we (s4 owners) could beneficiate at the same time from both, Anandtech's thorough opinion and Anandtech's impact on tech world.

We could all write to them. The more messeges they receive the better. They are perfectly aware of this problem for sure, but just in case...

I am a noobie junior member :p so my next suggestion could be a silliness, and however here we go: As this is a very important matter out of which all potential buyers should know about, Would it be appropriate to ask a senior and well connected member (such as AndreiLux, Chainfire etc..) to help us by contacting Anandtech directly? I apologize in advance if that is not a good idea :angel:
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
Anything that brings issues forward and helps speed along a fix/news is never silly, silly is when people put up with issues and not ask for better.
[Galaxy S 4 Q&A, Help & Troubleshooting] Acetonish:
guys , i just bought a GS4 yesterday.

however , before i did , i checked the demo in the store to check for the ghosting problem , it isn't there.

i am not sure if it is present in my GS4 that i bought , but maybe my eyes couldn't recognize it because this is my first smartphone.

anyways , i live in kuwait if it matters (octa core)

but i have no red/pink tint problem , at all.
[Galaxy S 4 Q&A, Help & Troubleshooting] Orical:
I'm T-Mobile Boston ma. and I don't have that issue either. I've looked since I got it and nothing.
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
I thought I was ok, screen looked fine for 1st hour or so, thought I was lucky.....then I went to the settings/more/about device, on that screen while using low brightness or auto in a darkish room I was shocked, the words change to a purple colour and become very hard to read as you scoll, after that I went back to another menu and my eyes were drawn to the issue on the grey bars.

I just have this issue, no tint or spots.

Really dont want to move to HTC one, so fingers crossed we get some news.
[Galaxy S 4 Q&A, Help & Troubleshooting] marcindpol:
I have the same problem with my phone, it happen only on the menus while set on low brightness. It does not bother me at all, it is only software limited and I am sure it will be fixed with upcoming software update just like they fixed redish , pinky tint some people were experiencing .
[Galaxy S 4 Q&A, Help & Troubleshooting] YUSoMad:
This is what I got from Samsung Tech Support.

Mikayla: I'm sorry, we have not received any such reported issues. Please be assured. I will forward this to our next level Samsung authority so that it will be addressed with next firmware update for your phone in near future. I apologize for the inconvenience this has caused to you.

[Galaxy S 4 Q&A, Help & Troubleshooting] LOSTLOGIC89:
Not in a min . Should be at least 10 min
[Galaxy S 4 Q&A, Help & Troubleshooting] samdsox:
I have smearing too, but its not an issue for me because it only shows up in about the phone settings, nowhere else. Its almost like my kindle when it changes pages. quick blink of wierdness and then what i want shows up. So i'm used to it. the rest of the phone makes up for it.
[Galaxy S 4 Q&A, Help & Troubleshooting] Shocky2:
I noticed this in the settings, thought it looked a bit odd.

Hope they can fix it.

I've just updated my phone to MDM firmware coming from MDF firmware. I now have the smearing problem so it's probably software related!

I have played around with my Note II for awhile. I noticed that there is also smearing to some extent in the settings menu, but it's hardly noticeable. I got my SGS4 this week, but sent it back immediately after noticing it had smearing problems. This was a Nordic version.

Yesterday I went to a store to check the screen for smearing issue. I compared it to my S2 and Friend's note and could not really figure out any issue. Tried it with various levels. I really do not think that it is something which would bother me and right away placed an order on ebay. Hopefully should receive it by tomorrow.

Hi Everyone,

What does RF Cal. 2013.4.27 mean???
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
Yeah they all say "oh we knew nothing about it" tbey just dont like to admit to there been issues. What I did was email again and add links to this page and to other well known sites that have articles about this....I used a phonearena link. Backs up what you are telling them if you can show many others all having same issue.
[Galaxy S 4 Q&A, Help & Troubleshooting] maroon1:
I have a question. Does this problem happen when you play games or watch videos ? Or it only appear in main menu ?
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
I've been sat on NFS MW all morning trying to kill my battery so I can get a full charge cycle in, and there's not a hint of smearing. Anything besides the menus moves along far too quickly for it to be noticeable, and you will HARDLY EVER have completely off pixels during gaming or watching movies, IMO of course...
[Galaxy S 4 Q&A, Help & Troubleshooting] inolvidable:
I wondered the same thing. I tried no game, but it definitely affect video. Have a look at this post: http://xdaforums.com/showthread.php?p=40843450#post40843450. In that particular video the low framerrate grabbed my attention so much as the rest of the problems. From that moment on I decided to get a refund and wait until Samsung fix those issues (via software or in new batches)

I also could reproduce the smearing/purple problem watching an episode of Battlestar Galactica (gray spaceships over black background). It was annoying
[Galaxy S 4 Q&A, Help & Troubleshooting] Luxxdroid:
ofc, try to play a game like Glow Hockey and just watch how nice the white ball smears =)
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
Will give it few more days for any news, its not that there is an issue, its Samsung not saying anything about it. While I am in the dark I have to fear the worst and as such return the phone.

I mean what if I keep it and Samsung dont fix it then what,what if I tried to sell it on Ebay next year and someone asks if its ok, or any screen issue lol
[Galaxy S 4 Q&A, Help & Troubleshooting] winlinmac001:
The Note 2 does not have black clipping; the S4 does (Depending whether you have the Snapdragon 600 or Exynos Octa). When I saw the demo unit at the store; I found the brightness on the Note 2 to still be more superior. The whites on the S4 were eh.
[Galaxy S 4 Q&A, Help & Troubleshooting] tuxonhtc:
Yeah I might be wrong on that. Didn't verify it myself, so my bad (and now I'm using perseus anyways) :p

Brightness I think S4 is brighter to be honest, but yeah whites that horrible blue tint that I can't stand (which hopefully is a calibration issue).
[Galaxy S 4 Q&A, Help & Troubleshooting] maggot_ff:
My Note 2 sure had black clipping, and so did most of the other Note 2's i have seen. Haven't seen it on any S4 though, but i have only seen Snapdragon ones. Also, S4 is a bit brighter, at least it has less reflections in, as the screen is actually surprisingly good in sunlight.
[Galaxy S 4 Q&A, Help & Troubleshooting] Punkrulz24:
Hey guys,

1st time poster and these look like the message forums to come to. I've searched around for an issue with my Galaxy S4 (AT&T) and have not been able to find any answers. This was the closest thread I could find to my issue but I don't think it matches. I want to post here before I make a new thread addressing the issue in case I am mistaken.

Since purchasing the S4, I've noticed a huge problem when looking at photos. If any photo I look at on the phone has black in the picture, the black area in the picture is completely pixelated and poor quality. Instead of being all black as in the picture the screen is now splotchy and horrible looking. The best comparison I can make: Windows XP (or older) and you don't have a video card driver installed yet. The resolution is terrible and the 256k color or whatever makes everything appear pixelated.

Has anyone seen this issue? I viewed the same exact picture on a GS3 and the picture looked as it should. I wish I could somehow show what this problem looks like, however when attempting to take a pic from another phone the problem didn't translate well. This issue appears to be slightly alleviated with a higher brightness. I haven't noticed any smearing or tints on the phone however. Hoping you guys can confirm this.

Thanks!

I have raised the smearing issue (and red pixel issue) with Samsung NL, they have forwarded it to "a specialist". Lets hope some good comes out of this. (BTW still havent got the OTA to MDM/N still on MDF)
[Galaxy S 4 Q&A, Help & Troubleshooting] cnever:
I have tried to get in contact with Samsung SA and their global site with a chat consultant - can't get through. My carrier said no one reported this problem. But the place I got mine from, one of the guys there also experienced the same with his phone. a Colleague at work also exactly the same thing. That is 3 phones doing this - I really think it is every single phone out there?

I am struggling to find a rom for the S4 - if it is fixed with custom rom then obviously it is the software and I can completely relax and live with it untill the next fix or rom - either way it will be perfect! Any suggestions the Omega rom links are currently not available.
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
I would say its most of the phones out there (mine also) take in to account people on here are phone nuts :) read up on stuff and know what to spot, so XDA people normally spot it but the average person on the street will not see it.....or will not know its a fault and live with it.

Its kind of down to use to point it out, Samsung must love us and hate us lol but again all should contact them asap and tell them of any issue, its the only way they will sort it.
[Galaxy S 4 Q&A, Help & Troubleshooting] cnever:
Is there an email address that we can use - channel and email them all together? I did email but it is one of those automated iframe things and hardly doubt it got to the right person?

Only thing that worries me is the hardware or software issue? Will I still be able to refund it after the out of box failure 7 day limit?
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:

I had the same probowm when I was on the UBUAMDE firmware..black clipping and red tint as well..I think it was poor gamma calibration. However the issue was quickly addressed in the UBUAMDK update.. if you want , in the meantime you can download screen adjuster from the playstore and set the contrast on anything past -7. Thie seems to mitigate the sudden drop from grey to black by lowering the contrast and giving a more even grey...bala_gamer suggested the screen adjuster trick and it works wonderfully..so if it helps you.. please thank him.

Could you please post the link to the game you are using at google play?. Thanks!
[Galaxy S 4 Q&A, Help & Troubleshooting] shortie1987:
Mate, I'm in agreement with you, I found exactly the same as you did, no smearing at all on glow hockey, despite being told otherwise :) I do still have the smearing issues in the menu though, but it doesn't really bother me at all. We can't have everything I guess!
[Galaxy S 4 Q&A, Help & Troubleshooting] D.O.C:
Then maybe the smearing issue is worst in some displays....or firmware is making some changes...that was my hidden agenda :P, to know if some smear more than others, now that we know all those that dont have red issues smear.

OK GANG!

I went to a technician that works for the Carrier that sold the phone. He had a look at it and then phoned the head of Samsung Vodacom to find out how to proceed. That guy then said it is a OBF (out of box failure), and he has not heard of this problem at all apparently. So it needs to go through the OBF channel and then if they see the same problem which they have to, cause 2 other people did then they will replace my phone.

The irony is I am sure that phone will do the same - but will keep you posted, now it is going to take 72 hours for all this crap to happen.

So to be honest, I think everyone should just go and refund their phones for a new one - and keep doing this, then you will see things happen :highfive: - the technician said if you find something wrong with the phone in 6 months you still able to do replace/refund for new phone but not sure how true this is.

Yes it is irritating and going to be for a while cause I won't have a phone and have to humour the people but hopefully something will come from it!
[Galaxy S 4 Q&A, Help & Troubleshooting] voodoochild2008:
Spoke to UK Phones4u.

Very nice and helpful, though they say they have not heard of the issue (I did say just google it :) very easy to find )

She asked what the issue was, and after I tried to explan the tech side she was......well I think it was a bit much for her, she was more for customer satisfaction really not a tech person, but after all that she has explained that I can get a swap or refund.

I did explain to her that I liked the phone and it would all come down to Samsung, will they fix it, can they fix it, so when I get back off my holiday if there is an update that fixes the issue then I will keep it, if not then they gave me permission to swap/refund (seemed all to easy, maybe because of all the emails I sent lol)

Anyway I still urge people to contact Samsung/place you bought the phone, you need to keep this going or they might just hope it blows away if we become silent, because lets face it, 80% of the people who buy this phone are regular Joe's, who either dont know of the fault/know what to look for/dont care because they dont use some of the features, these people will not even know there is a fault and as such say nothing, so its kind of down to us phone freaks to make up for their lack of knowledge lol
[Galaxy S 4 Q&A, Help & Troubleshooting] cnever:
The problem is I can do this all year (well not really) but I think with the second phone which is probably going to be like that they will as me if I want a refund or another phone... Problem is I really like samsung and I have a S3 already so loving the S4, got it for a reason... Dangit!

So yes, what would be great is if we can just get a "You will get a new phone if it is hardware and we release newer builds" or "It is luckily software and we will update it in the next update eta 3 months" or something...

And yes voodoochild, I know of two people that I made aware of the problem... The ones response was, oh I wouldn't of noticed it, nah doesn't bother me... Which in all honesty is something I picked up in like 4 hours?? I don't think it is just phone fanatics but perhaps just that the UI design is something I always focus on - ok well I design stuff for a living so I guess there is also not your usual customer, but common - it really is everywhere there is a solid background... Go to the google app store anywhere, where there is solid black and movement you will see it. I would rather have 99% black - anyway will keep posted with my refund :eek:
