[Q] Screen Quality? - Galaxy S 4 Q&A, Help & Troubleshooting

Hello all! I'm still using my Galaxy Nexus (Toro) and I'm due to upgrade next month, I'm now seriously considering the Galaxy S4, but the one thing that has me concerned is the screen quality.
As some of you may already know, the Galaxy Nexus has some odd color reproduction (especially in the greys) when the screen is anything below maximum brightness. It looks like there is almost a texture to the greys, and whites when scrolling. (See photos here)
I understand that this is the nature of the display on the GNex and I've learned to just tolerate it.
I really just want to know if the S4 suffers from the same issue at all?
Thanks in advance!

I personally notice the same thing for the greys in my S4, but I think is less evident than on the Nexus (my sister has one and I compared the 2 displays). In any case I think that it is a "feature" of AMOLED displays! The white instead is perfect and believe me is the best white I've ever seen on an AMOLED display!

Screen issues on the Galaxy S4? Where do I start!
*Pink tint
*Light Banding across the screen on low brightness
*Purple smearing
*Hue changing when keyboard is toggled
*Screen flickering when using data on white Web pages
*Purple greys on low brightness
I'm sure there's more!
The S4 is the worst of the Galaxy devices for quality control.
It was rushed to market to compete with HTC and Sony and so suffers a lot of issues.
Don't get me wrong, I love my S4 but definitely check the screen as soon as you get it.

Dont know about i9505 but the only "issue" i have on my i9500 is purple smearing that too on some 3rd party apps and barely noticable(after the update)...
And s4 has currently the best screen that u cn get in the market apart from iphone5 or note 2..but the latter phones are not full hd so s4 somewhat wins the round.

I have none of these issues, except the smearing, which with the update is fixed. Anything else is just perfect. I would say that this is the best mobile display put on a phone so far, and by faaaar the best SAMOLED out there.

The latest update did NOT fix the smearing.
It is just no longer as noticeable in the settings of TW.
All 3rd party apps and even other parts of TW still have the purple smearing, even the stock gallery.
It is simply a drawback of the AMOLED display showing pure black by turning off the pixels.

It's worth the risk mate. The S4 is still one hell of a phone!
It's just a shame Samsung were blinded by the $$$ and didn't put the S4 through proper quality control.
If you bought it I don't think you'd regret it

True, however for most of us it was most obvious in the settings menu, and it is gone from there, which is fine by me
However, you said it is a drawback of the AMOLED technology. I don't remember my old S2 having smearing issues? Or did it..

It's not a drawback of AMOLED it's a draw back of this display turning off pixels to make black.
The S, S2 and S3 did not shut down pixels for blacks.
You get better battery life and purer blacks on the S4 but the downside is the smearing effect.

Your right...we have to live with it...the pixel are going from off to on when scrolling through black menus..thats why this happens. ..older galaxies never actually cut off...if wanna fix this you can use screen adjuster and slightly adjust the rgb, this will stop the smearing but also stop the pixels from turning off when displaying black

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.

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!
Sent from my GT-I9505 using XDA Premium HD app
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.
In the previous firmware did not have smearing.

How's the screen for everyone?

Everyone who's owned a SIII knows the screen is completly useless when it comes to the sun being shined at it. Cannot see anything. What about the S4? Same issue? Just curious about to buy one
Also how's the screen for you all? =)

I don't have an S4 yet but a report by displaymate a couple of days ago showed that when you have auto brightness turned on the AMOLED screen is just as bright as the brightest LCDs out there (around 475 nits). Of course you can't set this amount of brightness manually since you would overheat your phone and cause screen burn in if you did. That is why Samsung only allows this for when you have on auto brightness. Since as soon as you go back indoors it will lower the brightness back down.
Long time S3 user (launch) and just picked up the S4 yesterday. The screen, in terms of quality, offers a noticeable improvement over the S3. I migrated everything over from one phone to the other and there's no mistaking which is which. The total difference, however, is less than the difference we saw going in the S2->S3 IMO.
In bright light, unfortunately, they're basically the same as far as I can tell. The auto-brightness setting seems more conservative on the S4 (possibly to help with thermal issues), but I haven't had a chance to crank it up all the way out in the sun.
If screen brightness matters a lot to you, I urge you to take a look at the EVO. The LCD screen on that is much improved, extremely bright as usually, and the blacks are getting considerably blacker (see anantech review). I myself played with it for a half hour but quickly jumped back on the S4 since it fits me better.
I've owned every galaxy phone since the galaxy epic. (Sprint qwerty phone) AMOLED screens are great despite no anti glare features.

Screen is great until your moving grey on a black background and then you have weird purple smears going on. Not sure if it's a faulty display or just 'how it's meant to be'
Sent from my GT-I9505 using XDA Premium HD app
The screen is stunning! Extremely sharp with smooth text and eye popping colours, its basically like Apple's Retina display on iP5 but with AMOLED benefits on top.
In sunlight it fares well from my experience, better than S3, IMO, its a lot less reflective.
Stunning!
6 Stars.

[Q] Galaxy S4 screen burn-in probability?

So. I'm trying to decide between the Galaxy S4 i9505 and the HTC One, and the only thing that bothers me with the S4 is the fact that AMOLED screens are capable of screen burn-in. I didn't see a single thread about S4 screen burn-in, but I know that for example the S3 had issues with screen burn-in too. I never used any smartphone except for Xperias, which always use TFT screens, so I don't have any experiences. My question is: Should I worry about screen burn-in or is it fixed? I would use the Google Edition rom which has black statusbar if that matters. Thanks in advance, ChongWiz

Hello friend, I too hate the screen burn-ins of SAMOLED screens. The screen on the S3 definitely had screen burn-ins (especially visible in dark rooms showing black images) but on my S4 I havent seen ANY screen burn ins at all. Yes the whites looks blueish and yes there is purple smear but the display still is amazing and doesnt have burn-ins :good:
Owned all versions of the galaxy series and I've never had permanent screen burn. Lots of screen on time keep most devices 2 years and no noticeable dimming either.

Thanks for the answers, now I'm sure I will get an S4 asap. Good day for everyone!
all OLED screen will burn in by design, include AMOLED, the different is just how serious, my 2 years old S2 have a little burn in at the notification bar (for the battery icon and clock area)
p.s. the blue color is the worst one, and green is the least, due to the material in use
In the video in the review below, the reviewer said that she had started to see burn-in on her S4 are only 1 month.
https://www.youtube.com/watch?v=C_APG3kLiYs
EDIT: though i have never see any burn-in on my S3 after several months, though i kept the brightness low and did not keep the screen on for an extended time with a static image.

Based on what??? All Amoled screens will burn in. All... of... them... Yours will as well. Apparently not everybody sees it but it will, 100.00% sure.
It remains an awesome screen though :good:
meh, had S3 for 7 months, not a single trace of burn in (checked with RGB full screen tests). i think people who get burn do too much of same stuff, if you message all day long and nothing else, messaging interface might burn in and such.
if you are a "normal" user, who doesn't get stuck up on one particular task all the time, you'll be fine.
I actually owned the whole Galaxy Series SGS1 to now SGS4 and i never had the burn-in issue yet to date, i owned every phone about a year and sold them to got friends of mine and still if i look at their phones i can't notice burn-in at least on the SGS3 i was last week, my GNex which had AMOLED too has a bit of a burn-in but not that you may say "omg that looks awful", you really have to look very closely, i actually think in that time where burn-in gets a serious issue you have a new phone anyway.
I had horrible burn in on my Note I.
Could see the full keyboard like a shadow.
Same with the top bar. Could see the battery icon & alarm icon.
finally got it replaced (screen only).
Burn in came back though.
Screen was noticeably brighter when replaced.

Its like a faint blue hue over the affected area in the begining stages of burn in which isn't noticeable unless you go into a display test app and look for it.

Note 3 has Smearing, Ghosting

Hi Guys
I got my Note 3 today. The first thing i saw was this purple Ghostimg..
Uncheck Auto Brightness and set the slider to -5.
Then in Settings and Contacts you can see Smearing like on the S4 (not that bad but its there)
If you use Tapatalk change to dark theme and scroll slowly..
The Grey Text gets purple... When you stop scrolling its grey..
This Su***
Sorry for my bad english
Sorry for DP
You can also see it in LCD Test (Amoled Ready) App.
Change Brightness to lowest possible level.. Then switch between black and darker grey.. You can see a purple bar between them
Edit: I tried the S4 Fix. Changed Contrast to -10 (with Screen Adjuster) and Smearing is completely gone
so note 3 screen is fine then?
Thinking of buying the Note 3 but really wanna know how bad the smearing issue is cause i bought the Galaxy s4 on launch day and couldn't live with the smearing issue ( my girlfriend also bought a Galaxy s4 on launch day and still has it..she didn't think the smearing was annoying..i hated it )
Could someone with a Note 3 try both things explained below on low brightness
1. Download zedge and search for black wallpapers..then while scrolling thru the wallpapers..do you so smearing..purple glow on the grey background in zedge between the wallpapers?
2. Choose a black wallpaper as background and install nova launcher...then on the homescreen set a widget with some grey in it like the stock music player widget and scroll between the homescreens...and also with some icons on the homescreens?
On the Galaxy s4 doing the above there was a lot of smearing..purple glow visible even after the fix from samsung cause they only fixt it in the samsung framework
Sent from my GT-N7100 using xda premium
For me... Its too much Smearing.. I sold my S4 because of Smearing.m And now Note3 is the same.. Bought it Yesterday.. Now i sell it on ebay.. i hate this ugly smearing.. its a no go for a 750 € Smartphone..i stay with my Note 2 -.-
Edit: Tested Zedge... Between Black and Grey Wallpapers massive Smearing.. very very bad :/
Yeah Samsung will fix this for sure.. But in Tapatalk ect Smearing will still be there

Gee, I have this issue with my Galaxy S4. I don't have the Note 3 but considering they have the same screen technology, the issue is probably with the hardware.
I've attached a picture which really shows the smearing.
1. Set brightness to lowest.
2. Open the attached picture in the galaxy app.
3. Zoom in on the picture.
4. Scroll up and down. You'll see purple shadow around the black edge.

I noticed it when browsing several forums that have darker themes, any black/grey transitions smear terribly with purple..
I don't think it's a screen tech thing, because fast moving films with dark scenes don't seem to smear, it only seems in the rendering of UI stuff..
It is hardware problem?
Sent from my GT-N7000
I think I read it is a screen tech thing - a side effect of the deepest blacks produced by turning off the pixels altogether. Then the smearing is caused by the pixels being turned on again but not quite fast enough. At least I think that was the theory.

You can reduce it a lot by downloading screen adjuster in the playstore and set contrast to - 10 to - 15 and then press activate

I tried with the picture someone attached, zoomed in with lowest brightness and moved the picture around. I was not able to see anything weird.
Definitely has it on mine at lower brightnesses, got it yesterday. VERY easily noticed in Tweetings where mentions are in a grey-ish colour. Only does it on text at basically minimum brightness, so I can live with it. Really bugged me on my S4 on text as it was apparent at slightly higher brightnesses.

Screen smearing on galaxy S5's as well

Well i just noticed the dreaded screen smearing/purple haze on my new note 3 when i had the brightness turned all the way down, so i decided to check my new S5 and guess what its there too!
FU samsung how can they not pick up on this???
Yes there are fixes but it shouldn't be happening in the first place if you want to test yours out download the pic below, set brightness to 0 and zoom in on the pic and you will notice pink/purple smearing between the black and grey colours when moving the pic around.
Hmm wonder why they made all the menu bars green? now you know.
Don't see any problem in mine.

You need to have the screen brightness all the way down and make sure your looking real closely.
Out of the S4, note 3 and the s5 Samsung has seemed to make it the less noticeable on the S5.
What you could be seeing is the after image of the screen. You're seeing pink shade because of the way RGB is showing the color grey. You're seeing smearing because you could be moving the image around quite fast and the display is not fast enough to trail your fingers.
I followed your instructions and could see nothing that you are speaking of.
I have also previously owned a Note 3 and did not experience any "purple smearing" either.
In my opinion you are grossly overreacting.

I started the "infamous" thread over a year ago http://forum.xda-developers.com/showthread.php?t=2252445
Despite some thinking it was a software issue, it's simply a hardware issue with the panel.
The smearing occurs due to the native refresh times of the panel when going from completely off to dark shades, I.e black to greys etc.
The reason it wasn't an issue on older amoled screens was that the pixels were not completely off when displaying black, which is why in a dark room you could see a glow to blacks and also the "infamous streaks and blobs".
On the newer samsung amoled screens black is completely black, the pixels are not illuminated.
Samsung are just using cheap panels.
I spent a lot of money on an oled samsung tv there was the same issue. Putting a film on like sin city would highlight it. I returned the tv.
^S5 is the latest, so it's definitely new. So, was it really the panel?
What application requires one to view a dark grey image at 0 brightness zoomed in at 100%?
Come now, this thread is surely to attract the likes of trolls, or have I missed something?
I have no smearing, probably its all in your shorts lol.

Ok lets be realistic, the people saying their S5's are not doing it are ether one of 2 things,....
1. Plain stupid and don't know how to adjust their phones display to reproduce the smearing, example: "homer285 What application requires one to view a dark grey image at 0 brightness zoomed in at 100%?"
2. or in denial and don't want to believe their perfect s5's could have such a flaw.
Because all S5s and note 3s for that matter are all shipped with the same display hardware tech, and no you don't have some super special s5 that has different hardware from everyone else cause your awesome .
Now saying that there are fixes for the problem, one can use a screen colour adjuster to keep the "off black pixils" turned slightly on witch helps big time but kills ur battery dead.

Not black on whole screen, but you may see pure black parts when you watch videos that are not on HD scale. Also, around 95% of movies have at least one dark or low-light scene.

Most of us are neither of those two. Just because you experienced it, it doesn't mean that everyone has. Phones are not made in a single batch/production date. It's impossible to produce millions of S5 in a single day anyway. All products sold internationally have the so-called batch date/number to trace possible problems. My previous S3 have the black blotches when screen is dark and viewed under very low light, but my friend's has none. Now, my S5 doesn't have any screen problems.

Have fun with your "smearing" lol
I can confirm this too on my SM-G900F 16GB model... The Note 2 and S3 i owned didn't have this, but the S4 does and now the S5 also....
When having a black background (and lowered brightness) you'll notice it when swiping through the homescreen pages.
I don't know what causes this but i doubt it can't be fixed, yet Samsung continuous playing it their own way by ignoring the problem (the 'anti-smearing' update they once released was a joke)
This should only be a problem at night or in low light environments(typically when screen brightness is very low). I'm pretty sure it's a hardware limitation of Pentile AMOLED screens with the diamond sub pixel matrix, and thus affects all GS5's at low/very low brightness levels.
I've suggested this a couple of times on here, I'll say it again: 1.Change the screen mode to Cinema or Pro Photo.
2. (More importantly) Download Lux(free) and change the White Balance to Fluorescent. This slightly tints the blacks, and greatly reduces the smearing effect.

The S3 had a PenTile AMOLED screen and it wasn't affected by this. AFAIK it's due to the Diamond Pixel layout Samsung uses on the latter Galaxy series.

Your right. I had that in mind, but was confusing Pentile and the Diamond pixel layout as one and the same. My mistake.

You need to have the screen brightness all the way down and make sure your looking real closely.
Out of the S4, note 3 and the s5 Samsung has seemed to make it the less noticeable on the S5.

wow, pathetic. I hate all the BS threads about how samsung screwed us on the screen. Basically, by saying to turn down the screen all the way down and looking closely, in a dark room, you are asking somebody to look for a problem that never happens in a real world scenario anyways? WTF is up with all the people looking for problems in technology? Honestly, why in tha hell do people always try to find the tiniest this and the smallest that in every piece of tech they own and then bash the constructor for it, things that in the first place only appear in VERY SPECIFIC SCENARIOS THAT YOU NEVER ENCOUNTER IN REAL LIFE?
