I found this pic from previous post in that I noticed that this person also having this tint issue but he didn't noticed..

Dont see red marker.. see blue marker which going to show the area. See it in low brightness.. u can try to pull down lil bit notification bar for decrease brightness.. u will notice the area which I marked(blue) is lil bit tinted blue or pink.. still its hard to notice

2 pic attached one is without marking or one is with...

Tell me is that normal then?
[Galaxy S 4 Q&A, Help & Troubleshooting] Mittaa:
Actually hard to tell !

If I want I think I can find an angle and a brightness level where my screen would show this kind of tint too, but in daily usage I simply don't think about it (on the other hand I,m not sure I dare to compare my screen against a good LCD screen LOL) ...

Anyway my point is that one have to make a choice ... I personally love the pure black, contrast and vibrant colours from Amoled.

Purple smearing has gone with GE editing ROM :)

Well it's still there but barely. It's acceptable in my opinion, not like before.
[Galaxy S 4 Q&A, Help & Troubleshooting] Mandeep148:
Thanx mate...

Sorry.. I know I am over questioning..and frustrating you.. sorry for that.. as u know spending 40k and after hearing that "your device screen is faulty"

It feels like you buy a lomborgini but after month u noticed its tata nano.. lol

So, its not feel good..

I have not issue with black levels.. I checked black levels at night.. its pretty good.. and 100%black thier and pixels are really off their.. there is no tint on black background..

Only doubt about tint on backgrounds like grey white cream,etc..

Ok, I shown my device to service guys..

they said " its normal... we cant change screen.. bcuz its already normal.."

Actually they dont want to notice.. u know its india..

Ok so, is that really normal?

When I put my old s3 and this one side by side I see how much green is the s3 screen, it's just a gama adjust I guess. I have smearing bars when sliding in black background menus while in low bright mode, also the gray has a purple tone but it makes the screen much better than the others amoled I've seen. Anyway I downloaded screen test app and we can see clearly that the screen is perfectly capable to show pure grays, blacks and whites...
[Galaxy S 4 Q&A, Help & Troubleshooting] Mandeep148:
So,Its normal?
[Galaxy S 4 Q&A, Help & Troubleshooting] edduart:
Yes and no, the normal should be that the all colors were shown next to real. But due to hardware limitation I think it's the better we can have by now with the high density amoled display. Anyway I noticed some roms make it really worse, like mdk for example, so it's changeable.

I have a pink tint on the bottom. This is my fourth S4 and none had a perfect screen. I just forget it and now I just want to enjoy my device.
[Galaxy S 4 Q&A, Help & Troubleshooting] eyecon82:
you exchanged it 4 times? sheesh...stop being so OCD and like you said, just enjoy your device.....

if you read this thread, everyone has this issue, so there was no reason in exchanging it 4 times....
[Galaxy S 4 Q&A, Help & Troubleshooting] saype:
Yes, but the first exchange was a 9500 for a 9505. The second, because the first 9505 had a terrible screen, very different of my current device. The third exchange was because I found S4 with a incredible price, so I bought another and sell my old, and for lucky I get the better screen than all others, but it have a pink tint on the bottom yet. But now I'm satisfied with my phone.

[Galaxy S 4 Q&A, Help & Troubleshooting] ANGEL4RIM:
I changed my ROMs many times in hopes to get rid of this issue yet its still there ... Shame on you Samsung for making this big mistake. If this happened to an iPhone they wouldve pushed a fix immediately . but bcuz this issue is Samsung's the y haven't even released a statement about it
[Galaxy S 4 Q&A, Help & Troubleshooting] eyecon82:
yea..with apple's twice a year updates....

this is the 2nd update to the galaxy s4 in under 3 months
[Galaxy S 4 Q&A, Help & Troubleshooting] trenzterra:
On the highest brightness setting, the lines appear only slightly faded and the blue part doesn't seem to change.

Honestly, I didn't notice it until it was brought up. Even then, I think it could be solvable with a software update?
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
Just to confirm:

This issue happens with EVERY single S4 out at the moment, those that say theirs don't do it obviously just can't see it!

I just spent my lunch break going from phone store to phone store (sad, I know) testing out all the demo models.

I tested 13 in total, 8 Black and 5 White. All i9505.

Every single handset I tested had this problem.

I pointed it out to 2 staff members in different stores and neither of them could see what I meant. Actually 1 said she could "kinda see it, yeah"

I think she was just humouring me lol

Sooooooo, let's hope this can be sorted ASAP, Samsung!

The problem appears in the Spanish units too. With higher bright it is less obvious but still happens.
[Galaxy S 4 Q&A, Help & Troubleshooting] MultiLockOn:
Okay I think we established that it's ubiquitous throughout the s4 production. The real question is whether it software or hardware, more likely the latter (which is a problem) and what to do about it

Swyped from a minimalist S2
[Galaxy S 4 Q&A, Help & Troubleshooting] Xander123:
In my opinion this is firmware problem.

In Polish version S4 is the same problem.

I had I9505OXAAMDE and there everything was ok, bit I had red subpixels on black screen.

Now i have I9505OXAAMDM, black screen is OK but I have smearing.

[Galaxy S 4 Q&A, Help & Troubleshooting] AVF Jay:
No way is this a firmware problem.

It's a hardware limitation with the screen.
[Galaxy S 4 Q&A, Help & Troubleshooting] D_Magic:
Me and my girlfriend both got an s4 on launchday. I have a black one and while scrolling in the settings the grey bars turn a little purple. She got a white one and her phone is 10 times worse...whole bars turn purple and the letters get fuzzy while scrolling so u cant read anything ( on mine the letters stay sharp )
[Galaxy S 4 Q&A, Help & Troubleshooting] Mittaa:
Went to a store nearby in order to see how big a problem the smear / ghosting is.

I didn't noticed color changes, but experienced it as if the setting bar height was changing like it was made out of rubber.

I tried it with different levels of brightness and true, its a bit worse on low levels.

In the shop the S3 was placed next to S4, so I made a side by side compare and yes it's more noticeably on the S4.

People are different and have different perception but IMO (and taking account my ageing eyes), it isn't a big problem at all!

I think majority might never notice it, and if they do ... they wouldn't care a bit ;)

Compared to S3 the S4 screen is much more bright and vibrant.

This hand-on experience removed my last doubts. I'm going for the S4 :good:
[Galaxy S 4 Q&A, Help & Troubleshooting] JmJ17:
So you say that not all units suffer the same effect. Have you checked if in your girlfriend's unit the parameters are the same that yours?

For example, it is reported that at low brightness the effect is worse.
[Galaxy S 4 Q&A, Help & Troubleshooting] prodigiez:

Yeah both phones are setup the same way...same display mode..same brightness level. Big difference between the two phones cause on her phone the smearing is alot worse...my phone still has it though

[Galaxy S 4 Q&A, Help & Troubleshooting] armedking:
Hey i was reading all post here about this issue and seems like all s4 versions have it .. so we better exeppt it the problem now is . Is it hardware or software problem? .. in my opinion it can be fixt in either way and i was thinking if this is caused because of how de amoled screen works like when its black al pixels go out so i think we can fix it with a update from samsung or good themer who makes the background from settings and contacts message etc to be white like in the demo versions of the s4 in that way all pixels are on maybe that solves it . And maybe that's why it was white in the first place in the demo versions .. just a thought and observation so no worries :)

[Galaxy S 4 Q&A, Help & Troubleshooting] bagmar.rakesh:
Assuming the software is the same on both the phones, its definitely a hardware issue. Or is samsung giving different displays based on model numbers, something which they used to do with their LCD TVs a few years ago.
[Galaxy S 4 Q&A, Help & Troubleshooting] Tinderbox (UK):
Well after the black crush/gray-scale problem on the note1 and the S3 were never fixed, i would not hold your breath on the S4, Samsung has the S5 to work on after all.

Hopefully i am Wrong.

[Galaxy S 4 Q&A, Help & Troubleshooting] eyecon82:
I think you are wrong IMO

samsung had a bad reputation of not supporting past products, but they have turned around

The SGS3 got the JB updated right prior to the S4 coming out.....with the old samsung, they would have never updated it forcing people to buy the next model

So, yes im sure they are working on the s5, but they have a dedicated team still supporting the s4, and s3
[Galaxy S 4 Q&A, Help & Troubleshooting] Tinderbox (UK):
If you look in my signature, i have a S3 and the grayscale is really bad, no details in low light video just large black areas, harry potter vids are really bad.

I have checked for updates, nothing, there is a video on youtube and they compare the screen on the S3 and S4 and they say the S3 display had a problem, and they fixed it on the S4.

try going to settings-->more-->application manager-->all-->click google framework services..clear data and stop...then try to do the update....make sure your battery is full, phone plugged in, and on wifi

when you do that, it should show you last checked for update in 1969...it will force a update...some get it to force on first try..some have to try more than 10 times....it kind of puts you in line since updates are rolled out in waves and since you just exchanged your phone and activated it, you're technically in "the back of the line" for a update
[Galaxy S 4 Q&A, Help & Troubleshooting] clonednull:
Im afraid the smearing issue is a hardware issue.

I suppose it is the technical design if this amoled screen, the position and the size of the single leds. I think it can be adjusted with software somekind (and hopefully soon on kernel basis as this is the only way it can really improve) but it will be present always to some degree.

Thats like people visions are also different. Yours must be really sensitive as most of the users notice it in someway others just see it everywhere.

WHen I first got the phone on april 27, i noticed the pink smearing issue right away

Even with the original phone that was stolen, after the first update it has disappeared and I never noticed it

maybe people are looking too much into it?

i really dont want to disappoint you mate but this issue is real and when you search arround you will see the facts.

when it wouldnt be why would samsung even notice in their changelog that they have fixed it?

quoting samsung changelog for I9505XXUBMEA:

but you know what they did?

their workaround-fix was to remove all "true black" backgrounds in their whole UI. you can still find the problem in non-samy apps.

anyway if someone is really annoyed by this problem there is some development going on by rlorange. he is working on an app wich is also a workaround but for all apps and the development is going on! :good:

i flashed the kernel that you have attatched but the smearing got worse now back at settings again (I9500XXUBMG9 with your kernel)
[Galaxy S 4 Q&A, Help & Troubleshooting] donalgodon:
It really is a hardware/design issue, and just as the previous user said, the Samsung "fix" was to simply turn off true black. The issue is that the pixel refresh cannot keep up with scrolling, so the 100% off (black) pixels don't turn on fast enough. Samsung's "fix" only fools the eye by leaving the pixels mostly off, but not truly off at 100% black. It's a latency issue, and it is hardware, not software.

It's the one thing that makes me want to sell my new S4, because no software update is going to ever fix it. They'll only be able to mask it or hide it, but it's always there. It's just less noticeable when the "fix" keeps the pixels on, rather than switching them off and then on again.
[Galaxy S 4 Q&A, Help & Troubleshooting] adrian_dh:
Thats good news. hope we'll get a proper fix soon. displaying grey instead of black makes the device inefficient when it come to battery usage. If the S4 does not display true blacks, whats the purpose of having a amoled display.! I bought the S4 for its super amoled screen! really disappointed now !

It's probably more to do with the different ISP imagine processing chip that is in the i9500 variant when he has.

Smearing issue

Hi all,

Just wanted to share my thoughts with smearing issue/blur text in settings menu when scrolling after 2 weeks of fighting this issue. I have read full thread and been with samsung support on the phone a few times.

How is the issue affecting me:

In the settings menu particularly in the About device menu where the writing is greyed out if you scroll the text will smear. Also in contacts if you scroll you will notice a blue shadow on the separator band between contacts (the grey line that separates contacts starting with A from the ones starting with B)

what I have tried to isolate the problem

First of all I have backed up my device and reset to factory settings thinking that one of the apps I installed might have corrupted the software/graphics drivers - NO JOY

I then called Samsung and they have suggested to boot the phone in safe mode and see if it does the same. Booting in safe mode helps avoiding previous step as it will load only the android and all the standard apps, any other application installed after purchasing the phone will not work in safe mode. After doing that, the issue WHAS THERE.

Went back to the shop I bought the phone to compare it with the one they were having. No issue on theirs. The difference: theirs was 4.3 whilst mine was already updated to 4.4.2. The store man than agreed to update his to latest firmware (4.4.2). One hour later when update was completed smearing effect appeared on theirs as well with the same intensity and symptoms reason why I believe is software.

Both devices were on the same non branded and unlocked android version. Interesting enough a colleague of mine has a S4 with Orange branded android, it is fully updated (4.4.2) and he has none of the issues I have. His phone works perfectly fine.

I think the only thing to do now is to report it to Samsung on their official support pages so they can rectify the problem.

Sorry for the errors, I'm not English.

PS: given the fact updates are released per region, if worths mentioning, I'm from Eastern Europe - Romania.

Hello All,

I have to agree with SlyRO here.

My Phone(I9505) is not rooted, unbranded and unlocked and currently updated to international version of KITKAT 4.4.2 and i also have this smearing purple issue.

Interesting fact or not to point out is that when i had the JB 4.3 version i didn't have any of this issue! So i am assuming it might be software related.. but weird this is we cant point fingers to kitkat update since people had this issue long before kitkat showed up on the market.

also two friends of mine have the S4 I9505 with JB 4.3 and they do not have the smearing issue.

[Galaxy S 4 Q&A, Help & Troubleshooting] FreezIn:
Guys this is not a software related issue. I believe this is really a hardware or a defective screen issue. The first day I got my phone on touchwiz ROM, non rooted, it had the issue already. I decided to flash CM 11 on it ( android 4.4.2 ) it was still noticeable. I now tried vanir rom ( android 4.3.1 ) it was even worse. Its now even more noticeable since the launcher somehow made the problem worse. This is indeed not a software issue. Most likely a defective screen.

I posted my findings in another thread regarding the firmware version and screen smearing issue.

I found that there wasn't any (or very little) smearing on Brazillian firmware VJUFNB2, but after flashing a new ROM version (same KitKat 4.4.2 version, different region), I noticed the smearing right away on first boot up. I am tempted to full wipe and install the ROM based on the Brazillian firmware thread to see if the issue is there or not. It would mean that the issue is fixable/region dependent and therefore something within Samsung's firmware.

Heres a link to the Brazillian firmware based GoldenEye ROM in case anyone wants to try. Its basically a stock based ROM but really smooth and has all the bloat removed.
