Hi,
I have my sgs about 2 months and I'm very happy with it. The only problem I have is, that sometimes there are strange displayinterferences.
It looks like there are moving waves from top to down.
Does anybody have this troubles too and has a solution for it?
Or is it an hardware error? The problem is that the error isn't reproducable.
Maybe somebody can help me, please!
Thanks in advance

I think I have also noticed that once or twice. I believe it can be seen when you have the android drop down menu (notifications etc) open and you start or stop WiFi. It must be some kind of interferance with wifi hardware. Normal wifi operation does not cause it, only the startup of the WiFI which lasts one second or so.
Yeah, i think this could be true. I also see it often, when I open die Notification bar. But I also have the same interferences, when I am working in apps. Maybe also the 3G connection could be the reason? Does anybody else have this problem.
Is this a problem, which I have to life with or could this be an error of the hardware(warranty)?

I have the same problem. Never on wifi tho.
Which firmware are you using?
Hi,
my firmware is I9000AUJF1(A1 branded from Austria). I don't know if the problem in your posted thread is the same. The interferences I mean only exist one or two seconds. There are horizontal dark lines which moves from top to the bottom. After some time everything is OK again. It looks like anything interfers the display(wifi, 3g?).
The problem of warranty is, that I'm not able to show the problem, because it's not reproducable.
Screen flickering under WiFi data transfer
I noticed this problem a couple of days ago.
Whenever there is some data transfer going on over WiFi, wherever I am browsing or some service syncs up the screen starts flickering and I have what I can describe as faint scan lines crossing the screen vertically like there is some sort of interference.
These are mostly noticeable on white and light grey backgrounds.
I have gone trough 2 firmware updates currently being on stock JPK rooted.
I have searched around on google and found on some forum one guy that was saying the cause is an interference between the WiFi module and the screen refresh rate.
Has anybody encountered this problem or these symptoms ?
Is there somebody around more knowledgeable in this issues that can confirm that this is a hardware problem ?
wow! , you might have a defective phone then.
I use WiFi very often, Wireless N at aprox 87 Mbps
that should be high enough to reproduce the problem you experienced, if i had a faulty screen
the description of the scan line reminds me of interference when you are in close proximity with another LCD or CRT screen causing the distortion field
OMG, I get this too. Usually happens on boot or when I'm browsing a data heavy website or using Android market. Are our phone defective? Does anyone else have this problem? I wonder how common it is.
does the scan line comes from bottom up
or goes from top to bottom?
very slowly or fast?
if you are pluged in and charging, also are you in a 120v or 240v?

They tend to be random and I'm on battery power atm. Also they're quite fast but don't last very long. They'll start then stop then start etc ..
Hi,
just for your information. I've sent my phone to samsung on friday. Maybe they find the error. I report, if there are new information.
Yep i have the same problem. Can t find the source though....

The lines appear from top and travel the screen fast.
Imagine a TV who for a second has problem with reception.
I am on 240 V.
Also the issue is much more noticeable when not plugged in.
If I have the phone plugged in its barely noticeable.
I will try to call the service and ask about this issue. I have a strong feeling that this is a hardware issue. But Besides the screen being defective I also think about the battery. Maybe when in high load (WiFi) it's voltage varies and affects the screen.
It seems if I uncheck Power saving mode in Settings>Display and also uncheck Automatic brightness things improve a bit.

Another issue to worry about .. God starting to think about selling this phone and getting something else. Stuck in a 2 year contract though
some one already reported this on another topic
it does seems that some version of the phone are prone to WiFi interferance
we still haven't found out what causes it exactly
for example i can not replicate the issue on my phone when using WiFi
found it
http://forum.xda-developers.com/showthread.php?t=793944
Cant reproduce it.
Not that I'm unhappy with it...
If this is a hardware issue Samsung should replace my phone. I am waiting though a little bit before calling the service to make sure that it is a hardware problem.
If I find that it can easily be fixed with a software fix, it's not worth the hassle of trying to replace it.
can anyone in North America confirm this issue?
i got a huntch it might be an Europe only issue related to the high voltage of the electric interferance nearby, like lights, tv, radio, wifi, etc.
Anybody else noticed that the screen is washed out/blown out sometimes after a video plays (mainly Netflix, maybe)? It seems to be a combination of increased brightness and decreased color saturation, making colors seem... well... washed out. It goes away after either shutting the screen off and on or switching to another app. I think. I haven't found the pattern yet.
I'm guessing it's Nvidia's Tegra 3 PRISM tech at play, and it's just not shutting off after the video app is closed. I'll expect a software fix at some point, but just want to see if anyone else is experiencing it.
Well son of a b... that is what is causing my washed out colors and gamma. I noticed it seemed to come and go. Unfortunately it never seems to completely clear up for me, even after going to other apps.
I tested this with the Transformers movie. After playing that a few seconds, I left and noticed the home screen looked really saturated, then went to the browser, and it was the same.
For me going to another app doesn't seem to clear it up, but it does clear up partially after a period of time. And maybe it might be my imagination, but it doesn't seem like it really ever goes back to normal until I reboot the tablet.
next to my work ipad.. the colors seem really blown out. =\ also there seems to be a video stutter / jittery issue during the panning effect. Played it side by side with my S3 and the s3 can render it just fine. What gives?
Haven't noticed anything like that after watching videos or movie on nexus 7. display looks great 24/7

No, I see it happen with YouTube and Netflix too. I was just trying to make a futile attempt to understand why this happens to some of us and not others. My guess though if you haven't seen it with other videos, the Transformer movie won't do it either.
I've noticed that it's most obvious on some screen elements, but not all. So, it's entirely possible, I think, for someone to be experiencing the effect and simply not noticing it.
I've noticed this as well quite annoying.

The after movie wash-out appearance was particularly noticeable when looking at small fonts on a white background. Such as this forum.
Yeah same for me! I'm on my 3rd nexus because of dust under the screen, I can't remember my previous 2 doing it. Will it be fixed by an up date doyou think? Or could it be hardware related?

I finished watching the transformers movie this morning. Looked great to me. I can't notice any washed out colours.
I just started getting the "whiteout" too. Not from anything in particular that I can tell, it happened twice coming out of sleep mode.
Anybody have a fix? Is it Hardware or Software related?
>Is it Hardware or Software related?
Take screen cap. If cap image is likewise washed out, it's not hardware. If cap image isn't washed out, then it's more complicated.

I tried it on all the same things you listed. Didn't notice nothing some of you described at all. Screen still looked sharp n crisp. Colors looked fine and not washed out.
Its more than likely the nvidia feature kicking in. Especially if you have brightness set up higher. Probably doing it to save battery life. I keep my brightness at 12% and its more than bright enough for me to see everything well. I heard the autobrightness likes to act up so THST could be am issue also if you have that on also. I never use autobrightness unless I take device outdoors.

Can you give me the quick answer on how to take a screen capture on the N7? Thanks!
Just took several screenshots and swiped between the screen that was normal screenshot and the faded screenshot and they both look the same for me, which is lovely with nice rich colours. If I stick transformers on for 20 sec its washed out when I exit, as soon as I turn the screen on and off its back to normal. I just think its a bug in the screen settings when exiting a move or game. Used to happen on my PC until I updated the driver.

You just hold the volume down button and the bower button, it will take a snapshotof the screen. I've tested it though, see my above post
I'm having the same issue too.
Happens when I watch a video on youtube, netflix or play movies. I use a brightness app to change the brightness levels and it returns to normal. I'm also getting the "screen flickering" issue described here http://forum.xda-developers.com/showthread.php?t=1740385
I really hope these issue with be fixed with an update. I'm new to android. Where's the best place to report these issues direct to Google/Asus?
>between the screen that was normal screenshot and the faded screenshot and they both look the same for me, which is lovely with nice rich colours
So it's probably hardware (display), or a combo of hardware/firmware.
Power-saving feature of Kai's PRISM display pertains to color saturation and brightness. As OP indicated, malfunction may be related to that. But it doesn't matter what the exact cause is.
It may or may not be fixable via firmware update. Suggest getting RMA process started, then sit on it for a few days to see if OTA fix happens. Don't wait beyond the return period. Make sure to ask for advance replacement if RMA.
>I just think its a bug in the screen settings when exiting a move or game.
If the issue was firmware-only, then it would happen to all units, not some. It's either HW, or HW+FW.
Edit: Suggest trying different movie players and different movies to find extent of problem.

So question for the community. If you're having issues with the "whiteout/washout", the ghosting and flickering... would you recommend getting a replacement or waiting for a driver / firmware update?
Does anyone have issues with the touchscreen skipping every once in a while? Occasionally, there is an area on the lower half of the screen that seems to be insensitive, but if you start touching around it, it goes back to normal.
I've discussed this with some fellow Z1 owners and it appears to be a relatively common issue. There is some discussion that it may be due to overheating or a software issue.
Anyone else have this problem?
Had this once while my device overheated hard(~47-48°).
Not sure if I have to be concerned about that, because otherwise it works fine.

Same here

At first I thought it was an issue with crappy screen protectors. The Z1 already has a anti-crack film on the screen so I thought that adding a poorly made screen protector would create too much distance from my touch to the sensor. However, I've tried replacing the screen protector and also asked other people with varying brands of screen protectors and it seems that the issue still persists.
The issue seems to occur most often on the password screen for me (which is particularly annoying).
I've had it too, lower half of screen does not register slides on login screen for a brief moment.. No overheat!

No overheat here 2 but with the same issue.
Also the last days i think that all the screen sometimes is more insensitive than usual.I have to touch 2-3 times to do what i want.
I think that is a hardware issue.
Have it sometimes as well sadly! Can't figure out when exactly it's happening though..
I find it very annoying when I'm scrolling and at the bottom part of the screen, the scrolling becomes a click, which brings me to a place I did not intend to go to. Hope it's software, but can't imagine that.
Happens to me as well, regardless of device temperature. Based on the seemingly random nature of the issue, it should be a simple fix via software update. A similar bug persisted on the 2013 Nexus 7 devices when you laid them flat on a surface.

Same problem here!!!
I think is a hardware issue. When you touch the alu frame the phone works fine. If the phone is on the table or in a cover the issue are immediately there.
Sorry for my bad english. Hope you understand
I noticed some small things and thought it was me but I guess this makes sense.
Could be worse, my previous Note 3 had multitouch issues and had problems register several fingers :silly:
Considering how common the issue appears to be, I find it hard to believe that this is a hardware issue.
I also don't believe it's related to overheating since it seems to happen even when I haven't used the phone at all for a long time.
It feels like a software issue to me since the issue sends to go away if you touch another section of your screen

When you touch the alu frame the issue is not there. Only when you use phone without touching the frame.
Must be some kind of hardware issue...

I am having the exact same issue. The weird thing is, is that it doesn't always fail to register my finger. I've gone a few days without it, then suddenly it's back again. Also in the Xperia Diagnostics app I could then see the phone failing to register a proper line, then 20 seconds later it's gone. Weird thing indeed.

Yes, I have it as well.. First of all though, to reply to a lot of people on this thread, it happens regardless of "flat surface, touching the frame, overheating", or anything else. It seems to be completely random with me. Sometimes everything is perfect, then it goes nuts for no apparent reason whatsoever. I'm almost sure it's a software issue, and hope sony will address this issue soon!
it also happens sometimes to me.
the only thing that helps is to touch the ground of the ac power socket. it seems like the screen needs much more potential difference between the pointer and the screen itself and after a while of using it the pointer (you and your fingers) are more loaded.
thats my theory to it.

Unfortunately, unlike the rooting camera bug, it doesn't sound like Sony has even acknowledge it at all.
Exactly this.

I often have to attempt inputting my password multiple times before I can finally get it right. I have since switched to PIN unlock. Really wish there was some sort of response from Sony.
I'd you're using pie then stop using it and retry the affected area. I had this issues because of the activation area causing certain keys on the keyboard to become non responsive.

Hi guys
Have a problem with my Xperia Z, screen seems to start flickering (3lines, from top to the bottom of the screen) You can only see this while playing games. I've already had a screen replaced due to the same fault. With my previous screen it started exactly the same. First I noticed playing the game. Gradually became worse and worse (in the space of two weeks). In the end I couldn't play or browse because I was not able to see anything due to the fact the whole display flickered. Looks like its going to be the same. Hope someone can help me with that. Appreciate for any help.
Regards Luke

I think u have a poor quality screen replacement... Mostly low quality screen have the problem of Flickr or lines goes up and down...
So I'm having some weird issue with my Sony Xperia Z, the screen works absolutely fine, but there's this mystical dissolve(my apologies, couldn't find the right word to describe this problem).
The phone have been dropped before, but nothing happend. It have always been protected by case and tempered glass. One day I noticed the text on menu starts to blur a bit. Then few days later the same started to happen with album. And the thing is I haven't dropped it in a long time. And I have never sat on it either, so that's not the cause.
And what's is most frustrating, that the pixels tend to dissolve only when picture is in background, if its pure black or any other color nothing dissolves. And screen works perfectly in games, but when I view pictures or i open even the menu it starts to act real weird.

PS - I already tried reboot in safe mode, complete factory reset through sony companion, opened it up and reconnected everything connected to lcd and digitizer.
PSS - Today I noticed that the picture blurs on colored image, while on black&white one it is perfect, any ideas?
I am facing the same problem. Havent got a solution yet.
Dont have a perfect solution but atleast i can help you with a trick of my own.
This is going to drain your battery quicker then normal
Go to google play and download screen filter and set it b/w 30 and 34 and adjust your phones brightness to half or even more than that
Im sure you wont be satisfied but atleast it wont give you tears while looking at the screen.
