Yes, the flicker is high when you open the keyboard on sunlight but is different then the gsm flicker.
You noticed the flicker in gsm mode?
Not sure what gsm mode is but I was just trying to send a text yesterday and noticed it. Could be to do with the keyboard because today I was just taking some pics outdoors and couldn't really see any flickering.

My device has the same issue. I claimed it and got another one -> same problem.
Some devices seems to be good. Two friends of mine have also a Galaxy S4, but their displays do not show the flickering.
My device is a black one, my friends have both a white one. Which colour of device do you have?
I don't think the colour is important, but I noticed that the displays of the white S4 of my friends are darker (when set auto brightness of / full brightness enabled). So I think there could be different types of display assembled in the devices.

The displays are all different on S4. I've had 2 now which had the screen flickering issue on gsm.

Screen Flickers to Black Clock
I have been having the screen flicker going to black clock problem on the S4 now for 2 months. After doing a factory restore and nothing installed or setup on the phone I did some tests. It happens only when there is 4 bars or less on the Vodacom GSM/Edge network. It does not happen on 3G, HSDPA or LTE. Setting the phone to WCDMA fixes the problem but I travel to places where there is only GSM/Edge signal. Funny if I swop from Vodacom to another provider the problem goes away. I would really love a permanent fix for this.
Swap the phone mate. I replaced mine and the new one is fine.

Hi All - had my Note for a couple of weeks now, hardly used the camera but just tried it and there is a pink tint/hue at the centre of the camera view area which shows on taken pics too. Wondering if anyone else is having this issue. I have the international/UK white version of the Note.
Its normal all to do with light note and s2 has issue

Yes Ive seen the problem with the S2, however its really noticeable and it seems that Samsung have not fixed the problem at all. Really quite disappointed with it on such a high end device.
i saw it happen once recently with low light and low screen brightness on one camera app. but didnt happen with other camera apps. dont remember which app though. so try other camera apps to see if it is an app problem. turn up screen brightness and see if issue resolves
this problem is very common (the HTC devices i owned had the same issue) and there is not really a solution to it for now. the reason for this problem is within the optics, it CAN be compensated software-wise, but there is no 100% compensation possible. also this occurs only for specific wavelengths, therefore the light-source is important too!
All due to cheap sensors. The sensor isn't big enough to let sufficient light in so the darkest part (the center) gets the weird pink effect. You won't see too much of this when you're out in a sunny day.
This is just the nature of the game with cellphone sensors.
hmmmm... it seems blue on my phone. not pink at all
mine is green..... :s

mine is a perfect mix of VIBGYOR pattern (white!)
mine is sometimes green.
but its seams to be problem with the AWB (auto white balance) and artificial light sources. If I change my WB to a daylight (or what ever) the pink/green spot is gone. When i switch back to AWB most of the time the pink/green spot is also gone
i would appreciate if you can test this
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!

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.
regards

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.

Old post but mine dose it too!! Galaxy s5
I've noticed whenever the keyboard is toggled on or off the greys change their hue.
It's subtle but most noticeable when on low brightness and in a fairly dim room.
I noticed it the most in the Playstore when you click the search bar at the top it brings up a list of resent searches, now hit the back button to make the keyboard disappear and the whole screen changes hue, click search bar again and it changes back when keyboard reappears.
Can someone else please test this?
I'm just trying to work out if my screen is defective or if it is an 'issue' with all S4s.
Thank you
Yeah, mine changes hue a little as well. Strangely I had my screens changed four times but this is the first time I noticed it.

Thank you for checking. It is actually quite noticeable when you're in a dark room, it's really bugging me!
This is my third handset, the first had a serious pink tint on the bottom of the screen and the second had a light horizontal band across screen when viewing white or grey images.
This one also has 'banding' on light coloured or grey images but not half as bad as my second!
I have the banding issue too! But my problem was mostly dead pixels and stuff. My current set has one tiny spec of dust under the screen but they told me I couldn't change it anymore.
It's a shame that you just can't seem to get a perfect AMOLED screen. There's always something

If you put the phone on lower brightness or auto-brightness, do you see faint vertical and horizontal "streaks" of discoloration or shading? It's especially apparent in the dark, and on grey backgrounds. My phone has this exact problem, and I tried taking it to a Verizon store to exchange it and they refused, because the two S4's on display had similar issues (although less apparent). So either this is a very common problem on the S4 or I'm just incredibly unlucky. Would like to hear from other Galaxy S4 owners to see how widespread this really is.

Strange, my S4 doesn't has.. But my old GNexus had vertical lines visible only with white or green background.
I think is lucky.. If you can, change it or ask to technical assistance Samsung for display change..

try to test the screen first.
Go to Dial Keypad and enter the code below:

Test your screen by dimming and check if lines would show clearer.

How were you able to convince them to change it that many times? All within the 14 days?

I didn't get a 1-1. Went to the service centre. First time it was an issue with the sound crackling but somehow they changed the screen when they shouldn't (and I still hate them for it).
The replaced screen had a greenish blotch in the middle, so back it went.
Third had two dead pixels so I sent it back.
Fourth they replaced on the spot for it had a big piece of dust inside the screen.
Fifth has a small speck of dust under the screen which they refused to change for me in the end.
Still quite a bummer that five screens later I still ended up with a less-than-perfect screen. But I just gave up and it doesn't affect me too much nowadays.
I have the same problem.

Yup, I have this issue too on my international S4 (GT-I9500). This only happens with grey. The screen tests for red, green and blue are perfect. And they're only usually visible in the dark. Best way to show them the problem is to search 'solid grey' on Google Images, save one of them and show them the image on full screen in the dark. After seeing that, it'll be pretty much impossible to deny that it is a problem. I took it to service and got a screen replacement under warranty, but it didn't help. Still has those stupid lines. Most apparent in the dark on solid gray. I'm taking it back to the store on Monday, if they replace the handset and that fixes it, I'll get back to you.
Me too
I think this is another variant of the smudges that are apparent in amoled screens sometimes. Search Google for lines in amoled displays or something similar. There's loads of threads talking about the same thing.
At any rate, it seems to just be luck of the draw as to how bad it is, or if you even get it at all.
At least, if you have them, they don't worsen over time, and any phones that are made with amoled screens can get them. I have two lines myself. I've just gotten used to it really. Don't see them now, unless I look hard for them.

Hi everyone, I have had my Nexus 4 for about a month now. When I was using it, I noticed a strange pattern on the screen. I looked into it and found out that it was the digitizer. After doing some research, I learned that seeing this was normal. Except, on my phone you can see the digitizer very clearly in sunlight even with the screen brightness all the way up. It also is visible when using the phone indoors with auto brightness. Is this normal? If not, does LG offer warranty for this issue?
