Smearing issue "fixed" in MF8 - The truth behind it - Galaxy S 4 General

So, we all knew that the smearing issue happening in our phones happened generally around images/text on a black background.
Many of us thought this could be a software issue but in reality this is an hardware limitation (I know many users already know this but there are some still hoping for it to be a software issue).
I had a lot of issues with the first S4 I bought. Most of the issues were around the back light bleed on the bottom and screen color uniformity. After 3 months battling with Samsung with no end in sight, I bought a new one, this time I choose the white one.
The new one has nice whites and the screen uniformity is close to perfect (or at least it seems so, so far). After checking the screen for some hours, I decided the phone was good to be used and started by updating the firmware to the latest available to me (MF8). After this I went to the settings menu to setup some options and I was amazed to see the smearing was almost gone. I never believed it to be a software issue so I was very surprised by this.
However, my surprise ended very quickly when I check the screen on a dark environment. Samsung did not fix the smearing (as it is a hardware limitation and not software like I always thought) they just changed the background of the settings menu from pure black to a very very dark gray.
This can be confirmed if you go to the settings menu and check the background. Then while in the settings menu, drop down the notification back. The notification bar is pure black, while the setting background isn't. Check this on a room without any lights and it will be very easy to detect.
The whole point of this thread is to inform other people from XDA that Samsung just used a workaround (like everything done by Samsung) to "fix" this issue. There is no way to fix this, this is a refresh rate limitation of the screen. If you want the smearing to be gone you cannot have pure blacks.

i never had any smearing on my s4 so maybe is not a universal issue

It's not fixed and will never be fixed.
Maybe except some dirty trick such as replacing pure black with dark grey at kernel level etc.

changing the background color from black to dark grey wont do anything samsung....
i wish there was a real fix but sadly i dont think there will be because of the way this new amoled works

It's the technology, it's the amoled, it's all about the inertia. Sell your phone If u can't stand it. It can't be fixed. Period. Deal with it or get different phone.

Smearing? Never experienced that in my i9500. Is it a myth?
Sent from my Galaxy S4 using XDA app

Some people seem that they don't care enough to even notice that the smearing even exists ...
Also in settings it was a bit annoying but i prefer to have pure black if that's the only disadvantage because i don't think it will proc in anything else other than scrolling because it won't need faster refresh rate ...
I'm not an expert in any form on this kind of things but when i upgraded my phone and saw no smearing in the settings i was first surprised but since i ve read that this is a hardware issue and i double checked it to notice that is a placebo ... but since my phone works as it should and doesn't annoying me with the things i want it to do i don't care that is that this "fix" it's just a cover to the problem and not an actual solution

Your phone has smearing as well. They all do. Not seeing it yourself doesn't make it a myth

wanna see smearing? get some white yellow blue or something like that walpapper (stock blue is perfect), install MX Player from Market.
Get to menu, scroll to the page when the icon of MX Player is, now quickly swipe from right to left, you'll see that black part of icon is extending for maybe 0,1 sec...
That's the smearing, but many of users are pissed with this minor thing, which I can barely see.

So you knew that there will be smearing issue before you bought S4???
And also quite surprised so many people haven't able to observe this issue in their phones.

Yes, I knew that, It's still so tiny tiny issue comparing to those on HTC ONE or Xperia Z (I had Z and One before S4).

Everybody should just download screen adjuster and up the contrast to 13 or 15
That way it will still be very very dark gray looking black with almost non existent smearing. Problem (kinda) solved!

THANKS

Screen burn in issue? Anyone?

Hi, I am planning of getting one of this beast. After reading on the internet about possible amoled screen burn in after using it. Could somebody share his/her experience regarding this? Is burn in screen real problem or small problem with this device? Thanks.
Sent from my GT-P7300 using xda premium
Never heard of screen burn in issues with amoled screens. I've had the original Galaxy S for over two years and have had no issues.

I have very, very faint screen burn in at the bottom of my 7.7 where the status bar is. Can only really notice if I'm looking for it on a white screen, but more obvious on a red screen. I believe the only reason it happened is because I took it out in the sun with me one day and put brightness up to 100% for like 90 min while browsing/reading because before that my screen was flawless. I'd say if you can keep it at low brightness you should be fine. If you're rooted I'd get a hide bar app. In contrary to all this though, my Note II has no burn in whatsoever and I leave that thing on auto brightness.

Thanks for the heads up man!
My Tab is an ex demo unit and had some massive image burn in due to it being left on while on display with the screen overlay still on the unit, so i had the big O and the smaller icons burnt into the screen, i only really noticed them when viewing solid lighter back grounds, and as i have used the tablet more for the purpose it was meant to be used for rather than sitting looking pretty on display the image burn has all but disappeared, can only really pick up traces of the burn if a really look hard enough
Here is link for tab 7.7 screen issues.

It has been already discussed before, and my question is has Samsung fixed the issue yet? Most of them say is a manufacture defect. Or maybe it just Amoled technology at infancy.

[fix]fix for smearing issue [updated 19/7/2013]

Update: 6/5/2013
* replaced method 1 with new method
Update: 19/7/2013
* added new hardware level fix for 9500 users
As of now we all know that almost all s4 units is suffering from smearing issue. After fiddling with some apps here and there I found a temporary solution , this should be handy until Samsung fixes it.
I suggest two method for this issue, Method 1 adjusts the rgb values of the screen(overlays) .Method 2 adjusts the contrast levels of the screen.
With both the above mentioned methods the black levels are not pitch black but will be on par with the blacks of s3 or anyother amoled screens. I prefer method 1, if you guys face any problems with method 1 then you can try method 2.
Method 1:
1.install screen adjuster app from market.
2.Set the values of green, blue, red between 5 to10(I prefer 5) and turn on the filter
3.job done
Method 2:
1.install screen adjuster app from market.
2.change the contrast level from -0 to -10(you can go upto -20 depending on how far your eyes can balance between smearing and pitch black)
3.turn on the adjuster.
4.job done
Method 3: (HARDWARE LEVEL FIX ONLY FOR 9500 USERS)
This method fixes the smearing at hardware level and changes contrast level of black backgrounds without touching other colors and dosent drains battery like screen adjuster. Thankst to @AndreiLux and @Slimmer77 for their contribution on screen calibration for 9500

One is software and causes battery drain and applies to all colours if you want it or not, and the other is hardware, costs nothing and targets only black.

Will give a 1.56% grey on blacks and removes all smearing. You need to set digital brightness reduction to 0 though since I didn't plan for this use-case and it negates the above "fix".

1.Install a custom kernel that supports screen calibration.
2.goto screen tab
*enable register hook
*set digital brightness reduction to 0.
3.Flash the attached zip file
4.job done
Users who hate the non black background(especially it looks poor when used along with smearing fix) introduced by samsung on newer roms can flash teh blac background mod attached in this post
Note: Running screen adjuster on background will disable the "install" button while installing apps manually, so disable screen adjuster before you start installing something and resume using screen filter after the installation is over

Personally, if you can fix or at least hide the issue with the above then at the very worst Samsung may change some settings in later roms to the same effect. I am hoping that it is actually a driver issue and a proper fix will come along....
This is an assumption but as the above works then I cannot see it being a hardware issue but then I am no expert.....
Won't this affect battery life? It seems to negate the power saving effect of AMOLED. I believe the smearing comes from the pixels going from off (black) to on (grey) and that switch time not happening fast enough. This app and workaround does definitely work, but it seems that it works because it's changing everything from black to veryyy very dark grey (still looks pretty black to me) however that means that the pixels aren't off if they're displaying grey instead of black right?
ok thx balagamer but its only patch for now hope samsung will fix it as i dont wanna blacks like on SGS3 and i really hope sammys fix wont be the same and they will steal the true black from us...that why i bought amoled right for the blacks

I believe this is indeed the case. Samsung could fix that by maintaining the pixels lit at the lowest power level, like with the previous Galaxy phones. I'm not sure if it's worth it though. Hopefully there'll be some even better work-around.

thats how samsung displayed the blacks in their past galaxy devices. With s4 the black pixels are completely turned off which is not the case with previous galaxy devices. hence even if samsung rolls out a fix they will simply make something similar to what we acheived with "screen adjuster". and dont forget you can still tweak the values in screen adjuster and find the best balance between black and smearing effect, the value "5" mentioned is suitable for me , it may or may not suit others.
so thay fu*ked up display also on previous phones and hide it behind the worse blacks really bravo samsung. I have my SGS4 from yesterday and have to say I see it clearly, the edges of grey lines are getting to purple colour. But I dont care because I can see it only if Im focusing on it. But for normal use you focus on text and what are you looking for and not to some grey lines right? So, Im rather happy with my super deep blacks...maybe some good AOSP/AOKP/Cyanogen will replace TW interface...

I'm not impressed by the screen at all, dead pixels, really bad ghosting and the screen turns pink at the bottom.
HTC One screen at least only had dead pixels.

[Q] Uneven colors from top to bottom

I just started using the Expanded Desktop MOD (No Navbar) and noticed that the bottom 8-10mm of the screen has a yellowish tint which isn't really visible on dark backgrounds like the Navbar.
It's clearly visible in apps that use the light theme such as Chrome, Hangouts.
The easiest way to check would be to open the Google keyboard in reverse landscape mode (volume buttons facing upwards) and compare the color from edge to edge.
Fortunately, my N5 doesn't have the overall yellow tint issue which my friend's N5 does and a lot of users have mentioned here.
My question is, is there anyone who has a perfect device? No overall yellowish screen and no uneven colors issue that I have.
I don't want to go through a bunch of RMAs and never get a perfect screen.
Please check your phone's keyboard in reverse landscape mode and post if you see this issue or if the colors are uniform.
Thanks.
My screen has a very slight yellow tint too at the bottom 10mm (the rest is fine, no yellow tint), but it is minor.

It's bad quality control if that's the case. I've had it for almost a month so don't think it's going to get better.
Anyone else has this issue?
I've got an N5 32GB that doesn't have the yellowish tint to the screen. Out of the few people I know that have N5's, none of them have that problem. I am wondering if the slight shadow effect is what is being referred to int his thread. Both the top and bottom have a slight shadowing effect on the edges of the screen with the Google Experience launcher. I haven't checked to see if you can turn this off but you can in Nova Launcher. When I get in from work, I'm going to round up some backgrounds to check. If anyone has any they think illustrate the issue best, please post them and I'll check back and try them with my device. For now, I recommend trying the Nova Launcher and turning off the shadowing to get a clear idea of what is going on with the edges of the screen.
Edit: Using Google Search and Hangouts, I don't see any yellowish anything on the edges of my screen regardless of the orientation. I also asked a co-worker to have a look as well and he didn't see any variation in the screen color on the edges, yellow or any other. The launchers I tried was Nova Launcher beta3 and the Google Experience launcher. Both yielded the same results.
Edit 2: It should be noted that I am not using the Expanded Desktop Mod and my ROM is stock with root and CWM for recovery.

Yes, i have this issue too. It is my second N5 (first one was a RMA) and i noticed it at the weekend when i flashed Purity ROM and checked a blank website using Chrome with Immersion/Expanded desktop mode enabled. Hmm. Besides that, my second Nexus 5 is near than perfect and basing on my research it is possible, that is glue that has to harden out - so it could disappear some day....? I don´t want to RMA it a third time.
I have also noticed, that the spot is getting stronger when the Nexus is on heat, e.g. with benchmarking or gaming. Weird. But that could be subjective.
I think i will have a look how it goes and than i will decide how to proceed.

Hi TR2N,
It has been a while since your post, but did your yellow tint on the top of your screen ever fade or did you eventually RMA or just live with it? I am dealing with the same issue and the tech at Google never heard about anything related to glue drying.

I did but the replacements had the same issue and were more yellow overall.
I've had my original phone this whole time. The yellow tint eventually goes away as you keep using it and the glue dries up.

KitKat has brought back smearing issue

Last night I was prompted to update to KitKat on my EE S4 and appear to have the dreaded smearing issue again!!!

It was fixed in previous builds (well reduced), when moving dark images around the oled ghosts and smears. Best example is in the settings menu, scroll it up and down and you will get black and purple smears on the section lines.

my next phone is gonna be a xperia i think, previously I had galaxy s2

You guys have a strange perception of what a problem really is. This smearing thing is so much overestimated...
Sent from Galaxy S4
It is very noticeable with black depending on how fast it moves on the screen.
Try to watch a movie with some 100% black parts, it makes a really sluggish effect, only on the black part of course which makes it even more noticeable.
Some people are just less affected (vision sensitivity) or don't have real black on the screen.
It's just a i9505 hardware weakness, no miracle. Changing the black in dark grey solves the issue but it uses more battery and prevent nice black to be shown...
Same here, same thing. But it randomly goes away sometimes
Yea I noticed this a while back on 4.4 roms. Not really an issue for me. The only scenario it comes in to play is when I am scrolling through the settings. VERY small price to pay at this stage for having the amazing screen the S4 has, wouldn't trade it for anything else out there at the moment. I watch movies etc on it and am very picky about picture quality (hence why I got S4), and haven't really noticed the smearing while watching movies. For me the speed and battery benefits of 4.4 stock roms FAR outweigh the negative of a smearing effect on the settings screen.
Am I the only one here who is glad that this is back?! I mean not the smearing but the black background in menus which causes this.
The smearing is barely noticeable and only shows up when my brightness is set to the lowest it can be.
My fix is simply to use either auto brightness or a minimum of 20-25% brightness.
I gotta agree that this is over exaggerated and is simply the cost we pay for having a device with an AMOLED display.
The upside is that we have the deepest blacks with this display, no other display comes close in that respect.
AMOLED normally doesn't have this issue. The S2 has perfect black without the smearing problem.
I think Samsung just wanted to save money or faced production issues. The Note 3 also have this problem but far less than the S4.

I could be wrong here but I'm sure the S2 didnt have the same deep blacks as the current AMOLED displays.
If I viewed my S2 I could see power was being used to illuminate the black areas of my screen.
But like I said I could be wrong its been 4 years since my S2 days.

Grey lines on display

Noticing a kind of very lite shade of greys in white screens irrespective of the brightness. No problem with any other colors. Can’t capture it in a snap. So tried my best to represent it in the image(attached). You can download the image and zoom-in and shake the image in the marked area to clearly see what I’m talking about. Anybody else having this issue? Is it huge issue as I will be working with photographs in the phone?
Just bought the device yesterday. Would be nice if someone can tell me how to convey this to the retailer without making him think that I’m crazy for a replacement. :laugh:
Unlocked model S7(flat)
I have found that all modern high density AMOLED screens have this to some extent. I bought 7 Galaxy S6s and none were perfect, with some better than others. 99% of people won't notice it. And even if you're someone who can notice it, sometimes it takes a couple weeks of owning the phone before you see it, and then once you see it, it's hard to unsee it. It's especially noticeable if you're scrolling and move your eyes up and down the screen with the content as it moves.

I saw it in the first day itself. Expected value for the price paid is not delivered means. It's cheating
Its very common on AMOLED devices unfortunately and my guess is that the vast majority of users cannot see it so lower # of units returned to samsung and they probably will blame it on QA. If a lot of consumers would start to notice it and demand for close to perfect panels then samsung will probably up their AMOLED game.
we bought 3 sgs7 phones all of them have this issue...how can such a company like Samsung do this ...like i cant see that LOL my vission on close distances is verry verry good so thats whay i saw those gray lines in a minute after buying one.i went to see my brothers gs7 after that and of course his one was the same and then after one week my father bought one white version so i thought that the 3rd one has to be a good one but NOPE it was the same story again...im very pissed so i will go to Samsung and tell them about it and will see what will they say...just to let u know guys i had similar problem on xperia z5 but instead of grey lines i had white ones and also some white spots and i send it to waranty and told them about the display issue and they have replaced the screen and now its perfect...so im goin to do that on Samsung aswell. good luck ppl
just to let u know guys i went Samsung and they replaced the screen but those gray lines are visible again so they sad that they cannot fix it and change screen everytime.... it looks like that alot of led panels are baddly constructed in the factory so i decided to return the phone.
I am on my 3rd galaxy S7. The 1st had the SD card connecting and disconnecting. The 2nd one the USB port would no longer transfer data(learned because VR stopped working) I am worried about the build quality of this phone....

I have exactly this same issue and it's driving me nuts! I cannot return my phone now, but it's very noticeable for me those grey lines when some other people I tried to show it couldn't see it...I hate AMOLED displays, I have never had a phone with an AMOLED display which was perfect, all of them always had some issue at some point. From Motorola, other Samsung, Huawei, all of them had some sort of issue with the display.[emoji35]

Replaced once, too. Mine was not a perfect line, like gray dust splattered along a line. Especially visible with grayish flat images, there were clear fluctuations on shade of "gray". Second device is almost perfect. If you look with magnifying glass , there were some pinkish littttle dusty dots on white, but it is really hard to see with naked eye. So happy with second now.
This issue is present because AMOLED screens don't use backlight. Every pixel is emitting light, and my guess is that they aren't distributing the same amount of brightness on every area of the screen.
It's noticable, but as some said to a very small amount of people, and it isn't that much of an issue if u ask me. Bigger issue is that amoled screens burn in over time. I could see my keyboard on white background on my S5 after a year and a half of use. Thank god that s7 has themes so I can change keyboard layouts.
Everything comes with a price... LCD's have their flaws, and so do AMOLED's.
Good news, its just a software bug on Android M, just reflash it to Android N and it will be fixed.

Not here, I'm running the latest beta on my s7 and the grey lines are still there, it's a problem with the display itself.

My experience.
Hi all,
I have an unlocked, rooted, Nougat ROM S7 Edge and I have been experiencing the same issue for 3 months.
The only way for me to fixed it is to flash Superman ROM, then the lines disappear. Any other ROM (Elyos, S8 ports, ...): I have the grey lines. A kernel issue?
Cheers.
P.S.: Flicker free kernel used to work with Superman ROM but if I flash it after any other ROM, my phone gets stuck in boot.
