Hello everyone
I just bought a galaxy s4 live demo unit and then i swap the motherboard , everything works fine but i look closely on the screen on white and other bright colors i can see some shadows on the screen with something that was once displayed on the screen , probably this was displayed a long time and somehow was imprimed on the screen , i don't know , i will attach some pictures , it is not so visible on that , but is quite embarrassing , on the upper part of screen it appear big "group play" and some strings , and in the lower part witch is more vissible i cannot read what it appear but is some text too whit some strings , the shadows appear like brighter color on the color that is displayed , i dont't know how to call them exactly, it is any way to resolve this without replace the screen ? why is this happening ?
I think is something common in demo units , i just see another demo with exactly same shadows , probably it is just temporary because both demo units are new with factory foil on them , and the shadows appears with both normal and demo motherboards , is there a way to fix this ?
It is called "burn in" I guess. Not sure how to fix it though...

It's burned in, every galaxy s unit had this issue. In fact all amoled screens do

Hi all,
I think my display has a problem of flickering: I noticed it going to "system status" window by clicking on battery, or signal icon. Here you have a gray stripped background that on my display seems to be unstable...something like flashing. I have the same impression if I look at the headers stripes of the tabs, where you find, "People", "Messages" etc...
The strange thing is that what ever I see, pictures, different windows, they all seems to be very stable, no flashing...flickering...problem.
Now I ask to myself, could it be an optical effect due to the pattern of that specific background?
I make the same answer to you all...and did somone notice the same problem?
Please answer me becouse I should have to replace it if I really have this trouble...
THX so much!

Did you try a Clear Storage followed by a Hard Reset?
@tnyynt
Thank you for your replay.
Other people suggested it to me. I've tried it right now and it had no effect, I'm still having the same problem.
BTW: Clear Storage performs by itself a HardReset after typing 1234...am I right?
I too am noticing this flickering on the top bar. I couldn't work it out. No idea what it is, but quite glad I'm not the only one with it. No idea if it is an illusion or a fault though. Can anyone else confirm?

Yes, you are right, but it's a different one than the normal Hard Reset.
Try to change brightness of the backlight, for example turn it off and check then.

thats normal. it has something to do with the refreshrate. that occours on every phone and pc monitor and so on. it always depends on what you are viewing at the momeent and often occurs when there are many very thin lines like at the top of the HD.
I have noticed no flickering at all.
@tnyynt
Do you mean I should perform a normal Hard Reset? How can I do it...I still haven't discover how to do it...
@Raziel1
It would be normal if everyone could see it on their HD, but it seems that only some terminals have this problem...Do you mean so that my HD has no problem?
THX to all!

A LCD display shouldnt flicker. It's either a hardware or software problem. Old CRT-monitors and TVs flickered because they "painted" the picture from top to bottom, and if they didnt do it fast enough it was perceived as flickering. LCD displays uses a dot matrix and shouldnt flicker regardless refreshrate.

Do you mean that I'm calling my display problem improperly or that it really can be a problem of this kind of display and so it means it is broken?
I have been noticing this exact same flickering, and couldn't decide if it was normal or not!?
but this flickering only occures when there are certain things on the screen like the thin lines of top of the home screen. its not the screen itself which is flickering. maybe it has something to do with vision and not with a technical aspect. the same thing can be seen on every screen i ever looked at. you can try it out, by taking a picture of a pc monitor at close range with high resolution. when you look at it and scroll around with zoom, it will often flicker like hell because of all the details and maybe downscaling or whatever

I havent seen the problem myself so it's hard to tell. You can often see by looking at it if its a software or hardware problem. If it's a software problem its just a certain part, for example a window titlebar, that flickers. This is usually caused by bad programming, the programmer has told the program to repaint with a certain interval even if there is no change. If it's a hardware problem the flickering usually isnt constrained to parts of the window, for example it doesnt follow the titlebar. Instead its usually diffuse parts of the screen that flickers.
@Marinese
Uhm...I'm figuring out how to test it...If I look at a picture, I can't notice the problem, and it seems to be localized on upper bars and on some particular windows I told before. If I could flash it with another ROM...but it's not HardSPL yet and I would keep it in warrenty untill my provider/seller TIM tell me what to do with it. So it could be a ROM problem too?
It would be usefull to have two of them placed side by side
and see the differences...
For me it seems to happen when the brightness is set to high, or I am in a well lit room with auto brightness enabled. With the brightness reduced I see no flickering...
Does that give any clue as to whether it is hardware or software? It seems to be dark colours that flicker.
@evilskanker
Uhm perhaps if you reduce brightness, you reduce the visibility of the problem as well...
I don't know about the dark colours...but I took a black picture and it doesn't flicker...
I have that exact same issue..
Altought I only notice it, on the upper horizontal lines on the RIGHT in TouchFlo3D.
What is the reason for that? And how to solve it?
Thanks.
I'm not sure we're talking about the same thing, but what I have is quick fluctuation in the brightness level without changes in the ambient lighting. You could call it flickering, although I would say it's not as fast as a flicker in my case. It seems to me it has something to do with the light sensor and its sensitivity. I would like to think that a ROM update will sort it, but we will have to wait and see. I'm not doing anything about yet.
@atomikpt
It's the same of mine and also try to go to "system status" window by clicking on battery, or signal icon and take look of what it happens.
@arisg
Nothing to do with your case. Consider that I desabled the light sensor and I'm using brightness to its maximum level.
Hello i have just received my nexus. All is good but ... Has any body can notice a litlle bit of vertical lines on white background on screen ??? Is this normal ????
Thank's. Anyway i just have a little light bleed not importante but these line .... Hum mm... Not very noticiable. You have to watch very well to see them.
I don't want rma lol .....

Hi all,
A months ago I bought a new, unopened I9506. When i switched on i realized it has a display failure. The bottom of the screen was pink on bright background (1st attached picture).
I took the phone to the service, they warranty replaced the whole front panel.
But unfortunately the new display isn't perfect either. The abnormal pink color ceased, but on the same area of the screen has different (brighter) color tone like above. I took it back to the service again. After a week they told me, that the instrumental measurement values are normal, and compared to other S4's there isn't any difference.
The fact is, the problem not so significant like before, but is see it, and it is annoying. I attached the current state (2nd picture), but my camera isn't good enough to show the problem properly.
I don't want to disassemby in the warranty period and the service won't solve my problem, so my question is there any software solution to balance the tone of screen partly?
And what could cause this failure? Interference of the antenna, or something push the back of the display?
I don't believe the replacement part is wrong too.
thanks
All screens are different...
Try to *#0*# then select "receiver"
Check the white tone..
I don't think it's defected..
I bought s4 3 tines. Every time tone is different. Amoled never same..
It's normal dude..

Hey guys i found that when i have a low brightness set, especially on greey white backgrounds like whatsapp or empty chrome tab, i have a greysh vertical(straight from top to bottom) line on my S5.
Is that normal Should i go for warranty ?
If i set the britghtness higher the line isn't visibile.
Does any one expericence this ?

yes I have the exact same thing but is on bottom of screen at low brightness...from what I searched is an hardware issue...beacause samsung phone are rubish (s5 is the last phonr bought from them).

Maybe it's a burn-in in the amoled screen. A photo showing the problem would be great.

It's a straight line so I don't think that the protector has anything to do with it. Even that's a rare zone, I wouldn't discard a burn-in in the panel. If you still are in warranty you shoud bring it to the nearest Samsung Service Centre. If you already lost your warranty, and you can't live with that line in your screen, you should replace you panel because that's definetly a hardware issue. Cheers!

Hello, been visiting the boards for a long time, but I didn't register because I had nothing to contribute really. <.<
I currently have a i9505 running on cm13 6.0.1.
Last night when I wanted to reply to a text I used the right side lock screen shortcut that's set to messaging the circular motion thingy messed up the edge of my screen. (I didn't realize until later that it's not actually a hardware issue if you ask me.)
Some pictures, screenshots don't register anything:
CAN'T POST IMAGES because I'm a new user. :/
It's on imgur, with /a/Murqy extension after .com. Album of three images.
Messaging shortcut thingy on the second screen is a lock-screen burn in, as is lock screen in the middle of the first screen.
Sorry for the garbage quality screens, I don't have any other spare phone except for the ancient Sony Ericsson with me atm.
At first this obviously looks like some display issue or a burn-in. I've checked the display, it has absolutely no scratches.
I've also read about the quality issues of some S4 phones and glass+display being glued together which can lead to yellowish tint. And how display breaks easily because of bad build quality and too much pressure being put on the display itself.
Anyhow, ever since that brown/yellow thing appeared the right/left lock screen shortcut animations stopped showing. And that thing is the exact size of the lock screen shortcut animation.
Also, those three burned in lock screen buttons, phone/unlock/messaging aren't really burn ins. When I try to press any of them in the bugged state when the screen is already unlocked, the dropdown menu activates. Also when I use dropdown menu myself, those 3 buttons are instantly gone without leaving a trace. And when the dropdown menu is activated, the yellowish corner translates from the background to the menu itself. Icons on the home screen in the background aren't yellow anymore, but icons in the dropdown menu are.
So, I'm completely at loss what to do here. I don't wanna use one of those burn in removal apps to mess my phone up, I don't have a warranty because I got it used like less than a month ago and everything was working fine. And I don't wanna take it to a repair shop because they'll just tell me the display is messed up.
There's just too much coincidence here for me to believe it's a classic case of display burn in.
Why wouldn't lock screen shortcut animations show up anymore if that was the case? Even on the left side which is completely fine. And it just appeared out of nowhere when I used one of those shortcuts. As if animation is stuck in there.
Sorry for the wall of text, but wanted to explain it in detail as I couldn't find anything similar anywhere else. <.<

I'm not familiar with burn-ins, but since it's a used phone the probability of the screen being messed up is high.
If it really is a software glitch, the only option would be to flash a different rom. If it continues, flash a stock rom via Odin. If the problem still persists, then it's most probably a hardware issue.
Remember, the flashes have to be clean flashes. As clean as possible. Dirty flashes won't help, especially when trying to find the root of a problem.
I've had it for nearly a month now and I didn't have a single issue.
As I've said, it's probably not a burn in because it just appeared like that due to one animation.
And since it's also there when I boot into recovery I don't think flashing a new ROM would help.

Is this gradient (around the icon) visible to naked eye? This is really nasty Just a guesswork: this could be one of failure modes for amoled. I have 8 weird rectangles burned in over the whole screen and really don't know where they came from.
Check this: http://forum.xda-developers.com/showthread.php?t=2603039 evidently even light from outside can burn in your screen.

Yea, it's visible.
That's the far right shortcut on the dock.
But the weird thing is that it just disappears if I try to click it.
Same goes for the lock screen shortcuts as I've said already, that's why I'm not sure it's a regular case of screen burn.
And when I pull down the dropdown menu, the color of the desktop goes back to normal, but dropdown menu icons in the bottom right turn yellowish, as if the tint translated to the screen that's being used at that moment.
After I realized that I tried to mess around with color saturation and brightness.
Changing brightness had no effect, lowering it would just make that corner darker, but as I dropped down color saturation on all of the RGB components more and more it became less and less noticable.
But the buggy lock screen shortcuts still puzzle me. They remain on the desktop after I unlock the phone, but are instantly gone as soon as I click them.
If it wasn't for that, I'd be pretty sure the screen broke because of bad build quality. I read about the display having too much pressure put on it, somewhat of a design flaw.
Gonna try that burn in app, what's the worst thing that could happen to a broken display. <.<

MuF123 said:
Does it disappear if you press and hold without actually doing something? Make a screenshot and display the image fullscreen as if it was lockscreen, will it happen again? While showing the screenshot, press and hold on the icon, any change?
Does all of the gradient disappear or just the icon burn in?
Click to expand...
Click to collapse
If I hold it, it actually works (eg taking me to messages or phone menu as if the screen was locked). It doesn't appear on screenshot, only after I unlock the phone. That's what's puzzling me, it's not actually burned in, it looks like an issue with the display when I change screens (from locked to unlocked or switching from desktop to broswer like in that screenshot with the burned in icon, as soon as I click it it also disappears, same as shortcuts).
And gradient gradually disappears as I lower the color saturation. Disappears fully at around 30% for all RGB components. But brightness is way too low then.

I get your point, like I'm leaning towards display issue but not a classic one but a weird one because it has issues with switching screens.
Idk, I'm gonna roll with this for a couple more days, if it gets worse it's definitely the display.

As you can see, after I unlock the screen, all three shortcuts are burned in.
When I press the burned in unlock icon it just briefly opens the dropdown menu (it wasn't me opening it at that point, when I clicked the lock screen icon in the middle)
Yellow tint in the bottom can't be seen on the video.
