This thread and the other one in General about the red on black should be stickied or somthing like that... Has anyone tried to inform techblogs/sites of the issue? Like Mobilesyrup, Engadget, Phonedog etc. I believe this way Samsung will notice it and will fix it quicker. These issues need to get exposed to the mainstream.

XXUAMDM
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
I'm running XXUAMDE firmware and I have no red tint but major smearing!! It's unbearable to me.

I really don't think this issue has anything at all to do with firmware.

In my opinion it is faulty AMOLED screens and there are 2 batches being used at the moment.

1 with no pure black (which is why there's no smearing) and 1 with pure black but this causes refresh issues and smearing.

I'm waiting to hear back from Samsung HQ today regarding the matter so I'll let everyone know the outcome.

[Galaxy S 4 Q&A, Help & Troubleshooting] sam2c:
The ones with the red tinted black are actually purely black during boot screen so they are fully capable of being black.

There might be two versions of the display panel but samsung didnt account for their differences in their firmware.

My version for example, that has the red tint, might need less current in the red, where are your that smears might need less current in the green

Another screen related issue:

I was watching a YouTube last night on my S4 and when I clicked on the screen to bring up the menu while video was playing the whole screen colour changed hue.

Can someone test this on their phone aswell?

Must be in a dim room and set phone to lowest brightness. Watch this YouTube clip in full screen mode and forward to when he turns the image black and white (just before half way through) then click the screen to toggle the menu on and off. You will notice the whole displays hue change when screen menu is toggled......very weird!!

People are truing to make problems now... Who watches youtube videos in a ***** black room with the brightness all the way down? If my TV was that dim, I'd be getting the backlight replaced!
[Galaxy S 4 Q&A, Help & Troubleshooting] Obagleyfreer:
No-one is making problems other than Samsung dude.

Does your TV rely on a battery for power?.....no.

I just happened to be watching that video last night and it was something I noticed, and it shouldn't happen (My S3 doesn't do it).

The room just had dim lighting it wasn't pitch black.

When you're using a cellphone to watch movies in a dim room it makes sense to turn brightness down to save power.

While I agree with you that this issue is not as major as screen smearing it is still an issue that should not be happening on a flagship phone that costs a lot of money.

I "upgraded" to the S4 from the S3 mainly for the "better" screen so issues with the screen to me are a real annoyance.
[Galaxy S 4 Q&A, Help & Troubleshooting] ewok666:
I can see the smearing on my S4 so I got the S3 4G out of the drawer and it does the same thing. Less noticable but then it a lower res screen. It's a bit like the scrolling issue on the Nexus 10 where the image is skewed while scrolling: It's there but how much of an issue is it really?

Black Clipping on GS4

Good evening

My GS4 has this issue to an extent as well and I believe it is related to black clipping, in that there is a slightly purple hue on some of the jagged blocks :(. When I used the standard gamma test ( in a darkish room), I observed that the screen gradually lightens from 21 to 3, then suddenly drops off to black for 2-0. I know this issue has plagued the Galaxy s 3 and the galaxy Note. Have any of you guys suffered this issue as well?

Try looking at dark videos in a dark room or try the standard gamma test (0-21 greyscale)

I have attached some pictures of the issue.

Also, here are my device details for your consideration

MODEL GT-19500

ANDROID4.2.2

BASEBAND I9500UBUAMDE

KERNEL 3.4.5-460554

I happened to check an S4 in a store today, I9505X. It didn't have "smearing" as such but very slight blurring. The thing that bothered me even more was the lag and stuttering. I just can't believe the amount of crap samsung stuffed on the phone probably without even optimizing it all.

It's got the smearing. It's not only on the settings page's, but on any grey 'stuff' on the screen, like in the (old) Playstore.

my first aid workaround for the Galaxy S4 text ghosting...

hi @ll.

sorry for my bad english, but i have really good news for some disappointed Galaxy S4 users.

yes the Galaxy S4 is a very very nice device.

i have see this text ghosting too and was very disappointed and frustrated. :crying:

the symptoms : i touch the display and scrolling in the settings menue or some other apps and the ghosting is starting, the text beginning to hidden twitch.

furthermore i see the text in the browser going a little darker and bigger if i touch the display. :confused:

but now the good news : :laugh: i have found a first aid solution, maybe later come a fix from Samsung.

the error is very simple.

the only reason is there is to many black contrast in the Stock Rom parameter.

please download from the Playstore the free app " Screen Adjuster " pusch the slider contrast ( not the colors sliders ) to " - 20 " ( or what you want, but minimum " - 10 "

after this, you see the fixed result. :good:

i like the display from the Galaxy S4 and thankfully it is not a hardware damage or bad controller.

it's only the black contrast parameter a little bit to much...

i hope your enjoy this workaround and now we can relaxed wait from a simple small Fix from Samsung.

have a very nice day.

Dear Mark,

Thank you for contacting Samsung Customer Support.

I can understand your concern when you have read these forums the second being German so I was unable to read it.

I have chatted with all our technical support advisors and asked them if any customers have called to report the case you have described and not one of them have had a call regarding this issue.

If you read everything bad about any device then you would never buy another product from any manufacture. Why not focus on the good aspects of the S4.

I Hope this helps.

If there is anything else we can help with, please let us know.

I have both the smearing while scrolling and grays turning into magenta (when I open/close the keyboard) problems.

Smearing while scrolling:

https://dl.dropboxusercontent.com/u/41361171/2013-04-29 00.43.21.mov

Grays turning into magenta when the keyboard is opened/closed (minimum brightness):

https://dl.dropboxusercontent.com/u/41361171/2013-04-28 23.58.42.mov

Especially check out the second video. The grayed out MessageMe contact list (RGB 50,50,50) turns into magenta (RGB 50,0,50) which appears to be triggered by an Average Picture Level change (due to keyboard being opened/closed). Interestingly, the change seems permanent: While the contact list is magenta, all grays on this display will be magenta. Pull down the notification bar and the brightness bar will also be magenta if the contact list was magenta. If you pull it down while the list is gray, then the bar is gray as well. Can someone please try and reproduce the second problem and confirm my unit isn't faulty?
