Screen issue or is it just like this?

My Galaxy S4 screen is strange. The top of the phone seems to be lighter than the bottom. As in when im texting the and I turn the phone sideways the blue bar that is there is a lighter blue on the left than it is on the right. This annoys me to no end and I want to know if this is normal or not. I also notice this in a ton of other apps when in landscape and it has a bar. Like Youtube.

it doenst look the same to me. This is my 3rd S4 already, The first one the charging port went, then the second had a dead pixel. Now this...

im terrified to send it back because they will send me an updated bootloader version back.... its not a bad issue the screen still works. its just really annoying. Custom roms and Kernels i will take over anything.

If I were you, I will go and get it exchanged even if it get you one with the new firmware. Rooting is less important than quality of the phone to me.

Plus in time (not guaranteed) Usually there will be an exploit hack to get root. I'm sure someones working on something. Especially since some were able to keep root after updating

I can replicate the issue you are talking about in the messaging app. About an inch of the screen at the top is slightly darker. But only noticeable on certain colors. I tried all sorts of pictures and other things, I can only see it in the messaging all. The issue is there with all screen modes.
The S II had a very similar issue. There was a triangle of screen that was lighter than the rest, and under certain circumstances you could see black splotches. But both issues were only apparent when you worked hard to see it, but never under "normal" use.
From what I understand having a little inconsistency in AMOLED screens is unavoidable. I would rather have this issue than the washed out colors of an LCD screen, personally. I would wager the issue is probably there on every S4 if you look hard enough, it was on every S II I ever saw.
The only issue I saw that I felt was worth getting a new device was burn in. On the Captivate it happened after about 6 months, the S II about 9 months. I'm hoping that Trend (each phone lasting longer than previous gen until it burns in) continues with the Note, S III, Note II, on to the S4.

This seems to be a common issue. I'm on my third s4.
Phone 1: vertical lines
Phone 2: pink tint at bottom (screen darker at the bottom)
Phone 3: pink tint at top (screen darker at the top)
You can try exchanging it but there's no guarantee you will get a better screen. In fact you may get a worse one.
The qc on these phones seem to be pretty awful.
If the problem isn't too bad I would just keep it and try to get used to it.
The galaxy s2 had an issue where the left side of the screen had a yellow tint compared to the right side. Samsung eventually came out with an update to fix this issue. Hopefully they do the same with this problem.

Touché - I'm on my FIFTH S4 already. I documented the 1st 3, but I've lost patience now... I don't know what to do further???
http://forums.androidcentral.com/samsung-galaxy-s4/304256-s4-screen-uniformity-issues.html

This has been common with quite a few of the phones I've had. It's more of a yellowish tint at the bottom. I read that its most likely the glue that they use and that it will correct itself with time. I just never waited long enough to see if that was the case and always exchanged them.

where is your phone made from? mine is made in korea, it works perfectly. I heard the ones that are made elsewhere has lower build quality.

G4 white static flash display glitch! POLL

Anybody else have this odd screen glitch anywhere on their display. Its like half a second white flash once in a while when I'm on Tapatalk, or the Amazon app or other apps.
Maybe its a bad display of my G4 or a 5.1 bug?
Edit....
I've since replaced my G4 with another new one with zero issues.

Should of added more to the poll, but my G4 is with TMO USA. Maybe the glitch is carrier independent.

Ever figure out the cause? I'm debating returning the phone

I saw this today on an H815 unlocked model on display at Best Buy. Only saw it when looking at a particular photo with a bunch of horizontal lines on it.

I think a software update should fix this or apps updated to support LP 5.1. I've only seen the glitch when I'm using an app, never on home page, or dialer, etc.
Hopefully its not a display defect.

Odd...

Nothing as described on my TMO variant.

could it be because the phone is in game mode which is a battery saving mode.

Here's the image I saw this problem on yesterday. Download it to your device, open it in the LG gallery app, and in portrait orientation, double tap the image to zoom in a bit. I saw the flickering on the stairs in the picture.

Nope.. mine seems fine..
Am I supposed to scroll around really quickly while zoomed in or something?

Just picked up my white Verizon g4 last night, haven't noticed this problem

Today on an international version, while using internet app to read this site, the screen gently faded really white, then a few seconds later faded back to normal again. It continued like this for prob 30 seconds. Leaving the app didn't help, but getting some black colour on the screen stopped it. No idea why it was happening... Something iffy with the display and maybe power saving though. Nervy now!

No, it happens while you are not moving the image or touching the screen at all. Might not work with that exact image I linked because the image on the device, while the same picture, was at a higher resolution I believe.
edit: I'll go back to the Best Buy today and film the issue so people can see what we're talking about.

Well only 3 people with this glitch? Maybe we have a defective display! I have 14 days to exchange it for another new one.
If your having this problem, please do the poll. Thanks

I suspect all have it, but it's hard to trigger. After I get a video of it at Best Buy, I plan to go around to some other stores like AT&T and see if the demo units there also have it.

Well crap. It was less noticeable on the G4 at Best Buy today. I could just barely see the flickering with my eyes, and it was impossible to capture on camera, at least without a tripod.

But you did see the flicker. I've noticed it could be a super fast flicker barily noticilbe to a 2 second square section looking like a static tv like on the movie poltergeist.

Yeah it's really quick, too quick to get a screenshot. It's mainly on scrollable apps. Just a thought, anyone using nova launcher? Maybe it's an artifact

TMO G4 here and I get a screen glitch occasionally. I can't consistently recreate it. It happens for a split second. The screen static affects about a quarter of the screen.

mine does that 2 could it be the kernel needs to be optimized a little better. Its like its underclocked to far or something. When I try to underclock and undervolt my nexus 6 i get similar issues. i bet they will be able to fix it with a kernel update im gonna go ahead and exchange it out

My personal G4 arrived yesterday and so far, after using it for about 7 hours screen time, I have not seen this issue. I know what the issue looks like too because I saw it clearly on a model at Best Buy. So maybe it is a defect in some models? Or maybe it only affects some firmware, because I doubt the Best Buy model is running the same firmware as mine, which is from Asia.

Anyone with dead/stuck pixels?

Got my first S7E, realized both the main speaker and headset speaker were very crackly. Did a swap and the new phone was great. On day 14 (luckily at least) a single dead pixel developed in the center of the screen. It appears on green, white, and grey backgrounds and is green in color. Not having great luck with this device.....
Anyone else experiencing dead pixels? I tried an app on the playstore which rotted colors for like 8 hours but still no change. Not sure if just need to swap it out again.
Thanks all

For some cases this could help to get suck pixels back to work:

Thanks. While that isnt the exact app I used it did the same thing more or less. Left it on for 8 hours and no change. THink I should run it longer? Also this may be dumb but is it possible the recent Samsung patches (which I know help with the touch sensitivity) might improve anything? I disabled the update app via Package Disabler for future rooting potential

I don't know if this would work if you use it for a longer period. Duo you have something to loose?
I don't think the April update will fix your problem.

How would one notice a dead pixel at 534 PPI? I'm genuinely asking since I would like to see how noticeable that is. Would it be possible for you to take a photo of the screen and try to catch that dead/stuck pixel?

For me it would be a pain in the... Staring at a bright screen and one pixel stays black...

See attached. Pixel is under the SU in SAMSUNG logo.

That's WAY too big to be a single pixel. The screen has 534 pixels per inch, and that "thing" is very big, so I think you have a cluster of dead or stuck pixels here, and I would get a new one ASAP if you still have the chance.

no chance to repair it by urself.
just take it for replacement
:good:

yep, definitely send it back under warranty from where you bought it.

Thanks all. I called ATT and plan to exchange again. They hadnt received my first RMA back (with the bad speaker) so once they receive it they can ship out the new replacement. Hopefully third time is a charm lol

White dots across the screen when rendering some images.

I don't know if anyone else have this issue since nobody has mention it on this forum or ZTE USA forum but there's a weird image rendering bug on mine. It basically shows a bunch of white dots that look like dead pixel across the screen horizontally. It comes and goes but it's pretty damn annoying to see.

So, it seen i am the only one with this issue. Strange.

I don't know about the dots, but don't you think "Candy" might get upset if a whole bunch of guys start calling her? It's usually not a good idea to post people's private numbers in a public forum. You never know who's in here.
Always thank those who are helpful...and just ignore those who aren't.

It reminds me of dead or stuck pixels on a DSLR sensor. DSLR's often have some means of mapping them out, but I doubt that smartphones have that capability.
Might want to read up on this and then decide if you want to return your device or have it repaired. Kind of a bummer, considering the short supply atm.
Search on google for "dead/stuck pixels on smartphones". Can't post any links yet.

But they're also showing up on screenshots, so it can't be an issue with the physical display. Makes me think it's some sort of software/driver issue.

Do these white pixels always show up in the same location? The shot you posted (with the flashlight) has a fairly well defined diagonal line/pattern, running from the bottom left to top right. Can you see the white pixels on a non-black background, like a light colored wall-paper? When you say "screen-shot", do you mean taken with an app on the phone?

It's a rendering issue not a dead pixel issue, which is good. The white pixels come and goes. The screenshot was taking on the phone with three finger pinch.

I factory reset the phone and the issue is still there which is extremely odd. I might have to RMA just for this stupid bug.

Might be memory issues or something else with the SOC. I'd definitely RMA.

Ever get a fix for this? I have the same issue and I don't want to have to wait for a return, just got the device today on my birthday :/

I have this issue on a couple of screens, one being my dialer. Here is a zoomed in screen shot. Seems I've seen it in one other display, but haven't noticed it since. I wonder about a fix?
Edit: I've kept the phone, tho I occasionally have a screen with this minor bug. It's clearly not dead pixels, but some software bug. It's so minor. I just wanted to bring it to light in case there was more to it, or a fix.
Love the phone!

Lol. So I am not the only one. FYI, factory reset doesn't fix so don't bother. It has to do with overlays.

It's actually possible for an effect that looks like this to be caused by memory errors. I'd RMA the phone.

Yea, i started the RMA process with advance exchange.
FYI, call 800-617-5065 instead of the CS number they have on their site.
Axon 7 customer are "VIP" apparently and that number goes straight to a CS rep right away. Kudo for ZTE for that.

Having the same white dots pop up on my Axon 7. Thought I was alone on this one. It doesn't show up in my pictures, but only the camera application. Maybe I could live with this.

Hi
Im shoting in raw with my zte axon 7 and And the dng file is completely filled with white dots evenly distributed over the entire surface o picture

Anybody having/had this weird display issue?

Hey all,
Yesterday morning woke up to my MZF's screen being all weird. Anything dark looks fine, but the white levels are very subdued and even seem to have a slight reddish tinge. And there's also these two black dots that wont go anywhere. Seem larger than just a dead pixel. This has been going on for a full day now; every once in a while it seems that the colors go back to normal, but the problems seems to always return.
Photos below show my MZF (right) next to my buddy's MZF (left). Both displays are at full brightness. Didn't purchase protection through Best Buy or Verizon, so I'm likely gonna have to deal with Motorola Customer Service. Yay.
Any one else seen this? Any ideas?

Do a factory reset and see if it calibrates itself

Tried those too, no luck. Have a new MZF on its way from Motorola, warranty is covering it.

I JUST sent my Moto Z Force in for nearly this same issue. I was cleaning the screen off and I had a black dot pop up and after about 3 hours of it showing up I had a bright yellow line running from the dot to the top of the screen. Warranty is covering mine as well.

I had the same problem with the color/contrast on my Moto Z Force, but without any black dots. Mine had the same blue tint/haze to the display. I did a factory reset with no luck. I am getting a warranty replacement today, but this morning the problem disappeared (6 days after the problem started). I think I'm still going to take the replacement.

I have a little different issue. Screen has 4 rows of multi colored small lines. Unreadable, yet the touch and buttons are still functioning, any ideas?
