Screen ghosting/motion blur - Zuk Z1 Q&A, Help & Troubleshooting

I've played around with my Zuk for about two days and I'm really liking it. There's however a pretty noticeable issue, regarding the screen: ghosting.
I'm not talking about burn-in, I'm talking about blurbusters com/faq/lcd-motion-artifacts/ type of ghosting, the one caused by long pixel response time. (I removed the dots so i can post the link)
You can clearly see it over grey backgrounds, and since that's lollipop main theme's color, it's starting to bother me.
Since this is the first time I've found it noticeable on a phone, should I be worried? Is there anything that can be done, or is my unit defective?

Bump? I'm returning it for another z1 btw, no one else seems to have this issue

Seems to be a hardware defect, i definately don´t have this.

I have it too but only when I browse through the settings.

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:
- http://mobile.engadget.com/2011/05/30/is-your-galaxy-s-iis-display-yellow-on-the-left/

- http://gsmarena.com/samsung_galaxy_...y_uneven_brightness_yellow_tint-news-2719.php
I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.
Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.

The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.
I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.
Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.
Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!
As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>
I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?
Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.
so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.
I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.
I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?
Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

How prevalent is image-retention/ghosting issue

I've noticed a very slight amount of ghosting on my n7, but most of the existing discussion relates the white-backed google I/O devices (and it's not as bad as some of those examples).
It's most noticeable when switching between landscape and portrait modes. For example...
- Browse threads on xda in landscape for several minutes: Strong contrast between white website and the black back/homescreen/taskswitcher bar.
- Press homescreen button (switches back to portrait).
- I can now see a faint impression of the bar running up the side of the screen, It fades after a minute or two. This is on the default wallpaper.
It's the sort of thing you may miss if you didn't know it was there.
It's not drastic, but my concern is whether it's likely to get worse. At the moment it's less annoying than say a stuck pixel (I'd kick myself if I went for a replacement and found not only did it have ghosting but pixel defects as well, especially given the annoying 'it's not a fault' stance that manufacturer's take on that issue).
I have the screen lift as well of course, but then it seems that's unavoidable?

I'm returning mine because of it. Sounds similar to what you are noticing, but is bad enough that if I spent long enough in the Gmail app I can actually read some of the messages in the imprint left on the homescreen. I noticed it as soon as I first turned on the device and googled for the issue - not because I read about the issue and went looking.
I get the impression it's only some of the I/O devices and a few early retail ones that have this issue. It's far more annoying to me than the screen lift issue and there are hundreds of posts on here about screen lifting. I think if the ghosting was as prevelant there would be a lot more posts on the topic.

I read about potential ghosting before the device was available, but had forgotten about it by the time mine arrived.
The first time I noticed it was after browsing the bbc news website, there was a faint impression of the site banner running across the middle of my homescreen. Initially I thought it might be uneven backlighting. Then I remembered the ghosting on the I/O devices.
So I wasn't specifically looking for it, but it might have taken me longer to figure it out what is was if I hadn't known.
I haven't noticed it on mine at all.
Sent from my Nexus 7 using XDA Premium HD app
I don't see it, and I just watched about 30 min of a video with a constant tv network logo in the corner.
Well, I went into my local store this afternoon to have a look at the n7 on display.
The screen was suffering from the usual separation (no surprises there), but I couldn't replicate the ghosting issue. Guess I'll be looking at getting a replacement for mine then...
Sad, really love the tablet, shame there are so many teething issues.
Mine is a Pre-Ordered 8gb model and I certainly have extensive image retention. For example, if I leave the default homescreen (with the transformer movie cover on it) up on the screen for anything more than 10 seconds, it will be retained when I scroll left to the blank screen. It remains for something like 3 minutes. Obviously I am RMAing the device and all I can hope is that the replacement doesn't have this issue at least to this extreme level. Is anyone else having this level of retention?

[Q] Strange vertical lines on brand new device

Hi guys.
Just recieved my brand new Nexus 4. Haven't rooted anything yet but I can notice some strange vertical "lines" of no colour. You can just say they are present and they give some weird discoloration, seen especially in the Settings menu,
Also noticed that my Antutu 3.0 closed itself (dunno why... it's 2GB of RAM...) only once and after one of several Antutu benchmarks there were some red lines... rectangles or some other stuff moving across the screen while in multitasking menu.
Now I'm a bit worried aboy the lines especially. Does it mean that I've just got a faulty device
Please check your Nexus 4's: just set the brightness to maximum and go to the Settings menu. If you see such not moving vertical lines (they are slight but still enough noticeable to see!) please report.
I live in Poland and I really would not want to RMA it since I would have to send it back to US...
EDIT: To add, the lines are especially seen on grey background, if it matters. But I can barely see them on my main screen too... I've also thought about the protective foil which is still present on both the front and back of my Nexus, but I don't think it may be causing it...
That's almost a description of the digitizer grid. Normally if it's at all visible it would require direct sunlight at specific angles. It would appear as metallic dots in vertical lines that reflect the sunlight. Perhaps the digitizer got bonded to the glass incorrectly? Give it a few days and see, it's well known that some bonding issues stabilize after a short while. If it's still very noticeable and bothers you, RMA the phone.

I'm almost sure it's not digitizer. I've seen it a few times on my dad's Xperia Neo V, and it just looks totally different. Also, I really can't see any dots. The thing that bothers me is the lines seem to be standing in their place all the time... I haven't seen this yet on any phone,
But, as you said, I'm giving it a few days. Also, I'll compare the screens when my 2nd Nexus arrives, so I'll find out if it's an issue or is it just normal (if it really CAN be normal...).
not in any particular order. factory reset it. get z-device test from the play store and run a test on the screen. dont run benchmarks on this phone. many people are having issues. and dont overclock. people are bricking their phones. i think they overheat.
Shouldn't be anything to worry about
Anyone got these lines or am I the only one to worry about them... :/ ?

Are you able to get a picture for us to see and compare?
I have lines, more like dots when angling the phone. They look like solar panel reflection, as a description. Only visible under strong sun light.
I also see rectangle impressions at certain angles;
-CC
Here it is.
They're a little less noticeable in reality (I wanted to show them clearly), but they are. It becomes really annoying especially on one-colour backgrounds (greys!) and when swiping screens from one side to another.
Maybe it will cure itself? I really wouldn't like to do an RMA since, as I already mentioned, I live in Poland, and it would be pain to send it back to US and wait another months for new one (likely with some issues too...).
Please report whether you've got these.
PS. I also see those rectangles, but only at a very specific angle, and these are really not noticeable at all. All that bothers me are these lines...
I also get these lines when I turn the brightness up high
So I guess I'm not alone with this (issue?). If anyone spots the lines please report. It's really important to me as I'll be living with this device for probably a year or so and I really don't want to know that my phone is defective...
It's so sad; except lines, the phone is absolutely perfect; no overheating, no earphone buzz (at least not noticeable during calls at all), no yellow screen spots, no flickering, decent battery life... And now this.
Crap. Maybe that's just another "Nexus 4 feature" ?
Got my 2nd Nexus today and it's also got that strange banding. Guess it's somehow just normal...

Not entirely. It becomes noticeable mainly in dark rooms, and I really like to browse the Web in my bed on my Nexus 4
I guess I am becoming used to it now. It starts to be less noticeable, especially outdoors where it can't be seen at all. So I'll just stick with that and probably keep the phone.

I am experiencing the exact same issue you are describing and am worried myself. I just opened up my phone today. Did you end up RMAing the device? With people claiming that this is one of the best displays out there, it seems like more people would notice this problem, especially since it is so noticeable from the settings menu.
Here's a picture of the screen banding.
Yeah same issue here guys ... Already some post about it. I'm used to see thèse now but very visible at high light and grey or setting background.

So do all nexus 4s have this issue or should we be RMAing our devices?
i have this too...
why does iPhone 5 get display from lg and dont have this issue but lg themselves do?
strangely apple can handle lg's screens better than themselves
kind of sucks...
this is one of those things that once you've seen it you cant unsee it
i also have a little bump on my aluminum bezel you cant see it but everytime i scroll on the left side on the screen i feel it...
So I guess the majority of Nexus 4 devices have that, but bany users can just not be aware of this issue.
That kinda sucks, but for this price... it's totally acceptable for me
Just like to say that I also have them, they are more visible at higher brightness.

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.
Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.
I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.
I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.
Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.
Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.
I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)
You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!
Good luck...

Dark horizontal lines cause ghosting?

Hey everyone,
I just got an S8 and am curious if a display artifact I'm seeing is normal for AMOLED or not. I tried getting a picture, but it is too faint to pick up clearly. What I'm seeing is that any dark horizontal line on a light background creates a faint ghost of the line extending to the screen's edges. The more black visible, the stronger the ghost. The ghost looks like a light single pixel strip at the top if the line and a slightly dimmer one at the bottom edge.
I see similar artifacts on my old plasma TV. It's like there is a total voltage limit per pixel row. If this is normal (it really is feint) then I don't necessarily care, but if it's a defect I will do an RMA. To replicate, look at an all white image with a few black lines running horizontally, but not all the way to the edge. You should see slight ghosting "finishing" the lines if this isn't just me. Thanks for any insight/help you all can provide.
Edit: just noticed the breadcrumb/forum path right here in XDA (its black underlines) cause the issue, so there's an easier repro.
Hi, could you either detail or link your solution? I'm pretty new and couldn't find it by searching.
Sadly I don't have a solution, just a problem I haven't had a chance to check another S8 to see if the problem is just with my unit, or all units. I did check an S7 Edge, and I couldn't create the problem, but that's still not exactly apples to apples. Will post again if I learn anything, but nothing so far.
Well from your description, I'm pretty sure I have the exact same problem on S8+, and although it is really feint, we've spent so much on these phones, that that little line to me is just infuriating, and I can't stop noticing it. I'd imagine it is actually quite common, but only a minute amount of people will have even noticed it. Will talk to Samsung tomorrow and see what they say about it.
Hi,
is this anything like this: https://forum.xda-developers.com/galaxy-s7/help/ghost-shadow-issue-black-text-white-t3576934 ? I`d also like to know if this "featrure" or bug.
Thanks

i have this problem too do you know of a solution.
Checked on my S8 but could not replicate your issue.
I think this is related to your particular device. It is a hardware issue which you should fix it by either sending your phone to Samsung or to local repair shop.
