Screen Tearing / Interference? Problem - Galaxy Tab 8.9 General

Recently the screen on my tab has been going crazy. Often, when I turn the screen on, it is distorted. It is hard to describe so I have recorded/uploaded a video:
Has anybody seen anything similar or know what is going on?

That is indicative of a bad connection between the display board and the display. I had this same issue and had to send mine in to Samsung for replacement. I have seen the same thing happen in laptops where the ribbon connector that carries the display data is poorly connected or has worked it's way out.
If you search youtube you will find people who have had problems with their Galaxy Tab 10.1 units showing weird/pink displays.

[Q] Screen flickering under WiFi data transfer

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)?
http://forum.xda-developers.com/showthread.php?t=753402
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.

Z1 Touchscreen Issues

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!
Sent from my C6903 using Tapatalk
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.

Is this the case? I don't think I've ever used my phone without touching the frame somehow.

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.

[Q] Screen keeps flickering

Hi all,
Recently my Moto X developed a screen issue. When I load any application, the screen flickers as if the window is being pulled to the top of the screen. The screen will flicker about 3-4 times, during which I can't get the screen to respond in any way.
This started happening after I installed the Google Now launcher, I've since uninstalled the launcher but the screen flickering will not go away.
Does anyone have any idea what is going on and how I can correct it?
Thanks!

Are you able to get video of it with another device? Is it the actual backlight that is flickering, or just the elements on the screen flashing around?
You described what sounds like the notification shade being pulled down. I've noticed that I get erratic behavior with my Moto X if there is any moisture on the screen (even a few very small drops), and some chargers. I used the BlackBerry charger that came with my Storm 1 because it had a very long (4-5 feet) cord on it, but it seemed to cause issues with the touch input. I switched to the cable that shipped with my phone and haven't had any issues since.
Maybe try wiping the screen down real good with a microfiber cleaning cloth. Not sure if screen protectors could cause this either, but I would imagine that they could interfere with the touch screen if not applied correctly or designed/made well.

Thanks fury683! Yes the elements on the screen flash around, very similar to what it would look like with the notification shade being pulled down.
I've given my phone a good wiping, it's behaving so far but we'll see if it's for good.
Have you tried restarting the device? Just try different little things and you are bound to find your answer.

Did you fix your problem?
I am having the same issue where my screen will flicker a few times as if another app is being opened by the app switcher. I noticed it happens when I am connecting or disconnecting from Wi-Fi. I tried factory resetting my phone and it did not help. It is very strange. Did anyone else experience a similar problem or find a cause?
Having this issue too — screen flickers when moving back and forth from wifi to 4g
Yes! Took me a while to connect it to offline/wifi/4g transferring, but my screen flickers 3 to 4 times (basically the view refreshes the same way crappy apps that didn't bother programming a transition go from screen to screen) every time I access an app that uses the internet after this transition between data sources. It is infuriating. Anyone ever resolve this?

Touchscreen issues

I've experienced some serious touch issues in the past two days. It's happened very randomly and I can't replicate the issues. The screen losses touch sensitivity and I can't do anything, then it randomly comes back after 10 seconds only to animate every touch I made during the 10 second lull.
Has anyone had any touch issues like me?
Edit: disregard this post. got the forums mixed up with another device.

sounds like a software glitch, is anything eating up the processor?
I'm on LRX210 out of the box. I haven't had any battery stat app running but nothing unusual is going on in the regular battery app
I have this issue as well. Drives me nuts when I'm playing clash of clans. Found a sprint forum post that says it could relate to screen protectors? I have an invisible shield on right now.

Have you updated to 5.1? Since 5.1, there were significant changes that appear to have been made to proximity sensor that seem to be affected by any sort of screen protector that may cover it. If your protector covers the sensor, then I suggest removing it.
I haven't. I currently have the notification on my lockscreen (since I can still use the power button and view that basic info). It simply just stopped working while I was using it. Going into the Sprint store early this afternoon
My N6 arrived yesterday and was immediately unusable. The keyboard filled in a ton of garbage when I was asked to first enter my name ... Power cycled to try again and have had nothing but reliability issues with typing at times the screen will lock while trying to type (no response) or assume I've clicked when I haven't which makes accurate data entry impossible.
wiped, reset and upgraded software from 5.0 to 5.01 to 5.1 - had to remove my ATT sim which initially blocked this process and reset. Issues are still present seems like the screen is defective.
Support has issued an RMA to return the device after suggesting they would replace. Not a great start.
im having the same issue with my nexus, i went back to stock, not even rooted anymore, still doing it, its driving me nuts..
RMA. It's quite obvious you have a hardware problem.

Although we're in an pls thread, I tend to agree. If it was a hardware issue, I don't think we'd see the OS acting out the touches later.. It means the hardware actually accepted the input but the OS didn't do any thing., Likely an OS hang or something.

[Q] Intermittent smearing (blurry) screen

Hey all,
I got this badass LG R watch for Xmas and it's never had a problem. Then a day or so ago it's started "smearing" on the screen. Anything white/lighter colour sort of ghosts or glows like it's being viewed through frosted glass.
The touch screen still works and any and all functionality is still there with no problems. It's only the view that's sort of washed out. I don't use "always on" and it's not screenburn as I've tried different watch faces and it still does it.
Worst part is: It's not permanent. It's completely intermittent and I have no idea how to duplicate it. I went to take a picture of it to go with this post, and now it's not even bloody doing it.
Not sure if it's related or not, but I've been having difficulties with my phone's OS upgrade at around the same time (4.4.3 is giving me ****s) and it's paired to that, so I don't know if that'd cause issues. Dog knows that the phone is having issues...
Any help/advice is much appreciated! Cheers!
Have run another upgrade across the phone and it appears to be bringing down the frequency of the blurriness. I'm seeing it only once or twice a day since then.
Any ideas?
