White Line 'flashes' on N7 Screen

Hi,
Every now and again, in either game or browsing with Chrome, a white line flashes across the full width of the screen, doesn't happen very often but would you say this is a software or screen issue?
I also have a couple of pixels in the bottom left which I can only assume is dead pixels, but they only are visible when the background is black, so are they dead pixels or stuck pixels? I've tried one of those apps that supposedly fix the stuck pixels but they are still there.
Any thoughts?
Thanks

The flickering SHOULD be fixed in a firmware update. Regarding dead pixels, you should return it.

Vsync isue?
I'm really curious what this is... it was described well in the general section by markfid like this:
I've also been seeing some issues with the screen, not sure how to explain them but it's like screen taring, that you see in games or like an old CRT monitor when it get's degaussed. It's a line from one side of the screen all the way over to the other side (Held in portrait, from left to right) for a fraction of a second. Very quick but when reading a book on a white background noticeable. At first I thought it was just my eyes getting tired, but it has happened 10 or 15 times so far (with ~5 hours of use).

I've seen that same screen tearing issue! I thought I was crazy because I've only seen it like 4 times, I think always on white screens. It happens really fast and is almost unnoticeable. I'm not sure whether it's a hardware issue or a software issue with the vertical sync in jelly bean

All quotes are from the screen separation "fix" thread.
I'm seeing the same thing.. like when you overclock a gpu or like the vsync is off or something. I's gotta last 1/10th of a second, and on irc user "speechles" says he sees it most when scrolling text and the gpu can't keep up.
Anyway, you're not going insane. I see it too.

Thanks, glad to see I'm not the only one... So going by the fact this is affecting a number of devices it might be a hardware issue?
I'm not sure about the pixels, there's probably 4-5 in a line and they go from dark to light from the top to bottom, basically a gradient but like I said they are only visible with a black screen... Might ring Google and see what they say, not sure if it's worth sending back...

I'm pretty sure I have what the OP first described too, but only when music is playing (either through speaker or headphone jack).
I already started the return process, but I'd like to know if this is software or a bad screen. I tried doing a factory reset, but the issue persists.
Maybe there's still hope for a software update.
I wonder if this issue is present in other roms.

I sure hope you're right. Seems like a relatively few amount of people have this line flashing/screen tearing problem compared to the number of people that are just experiencing flickering at low brightness.

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.

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.

White vertical line on screen Moto X style

Hello,
I have a Moto X Style.
Just a few hours ago started seeing a white very thin vertical line in the middle of the screen that goes from top to the bottom.
Didn't do anything special with the phone, scrolling facebook... just turned off the screen, and then turned it on and voila... it's there
The line is most noticeable in bright blue screen. Tried to take a picture of it, but doesn't have good camera so it isn't noticeable in pictures. Also it doesn't shows on screenshots and it appears even in recovery so it's definitely hardware...
The phone is only 3 months old... But I have unlocked the bootloader and rooted so I think the warranty is void...
Does anyone have/had some expirience with this and can help me?
Or the only way is to pay for a repair?
Thanks in advance...

If no physical damage moto will repair unlocked phones that have hardware failure. Best to get a ticket started and get some help over in their forums. Advanced swap is best even if it costs a couple bucks.

Anyway, yesterday happened another strange thing. I was taking pictures with the camera, then noticed that all the screen covered with white horizontal lines half transparent as if it is some sort of interference.. Restarted the phone and the lines disappeared, but also the vertical line got much thinner. You need to search for it really hard to find it. So maybe it was stuck pixels or something? I don't know
So it leads me to confusion. Either i leave it as it is as the problem is barely there, but then I'm afraid it will come back later, or i talk to Motorola, but then how am i gonna prove them if they won't find the line?
Thanks

I would discuss it with them regardless. If you still see the problem then they should be able to as well. Be persistent and very detailed about the problem. If you can get photos magnified showing the issue more clearly, even better as it clarifies the exact problem.

OP already stated it doesn't come up in screenshots. It's clearly a hardware issue...

I have this issue I believe. Except that it's when I dim the screen the previous images on the screen will not refresh.
See video I shot of it, at 1min 30sec I can start to see the ghosting. The white lines come and go too, usually when the screen is off and I wave at it to get the circles to appear so I can pause/play music. The more black on a screen the more likely it is to get lines down it.

Any luck in fixing this? My phone has the same issue and I keep reading things that say its a driver problem. Really seems to be hardware to me though, given that the same issue shows up in recovery mode...

Hi, same issue here. Had it for ages now, tried to return mine but Moto refused repair as my bootloader is unlocked. Have this issue in each and every ROM I try, stock or custom. Definitely seems like hardware.
If I keep the screen brightness up above 50% it's fine but anything below about 50% and it's unusable.

Same issue since some days

Edge tint calibration after update, missing blue screen.

I have seen a few YouTube uploads and other users describing that during the edge tint adjustment the phone reboots and a blue screen appears with an animation that resembles some kind of firmware adjustment.
I don't get that blue screen and don't notice any difference adjusting the red tint that for me appears in the top of the phone.
Would like to hear if the adjustment worked even without that blue screen or other thoughts about this issue.

if you check local "red tint" thread (and it's huge), nobody had experienced any extra blue or other screens or double reboots (like the instructions on the Edge adjustment screen state). also, just like you, many don't notice any changes after adjusting the edges color temperature and rebooting. so either that "extra" adjustment screen was Korean update specific or Samsung has butchered international update. or, which is even worse, many screens are just defective and beyond any software fix.

Me either
Yeah, I'm also facing this issue either. So bad that our unit didn't get that blue screen and edge screen still red.:crying:

Well mine did the blue screen and rebooted and my edges are fine now

Ditto here. Actually, it was the second time I did the calibration that I got the blue screen with some white Android figure (didn't really pay much attention), and a reboot. Fix was effective at changing screen edge tint...which I'd likely never have noticed had there not been all these threads re same. VZW S8+ here.

Okay , yeah I've read the thread shallowly, I can't remember anyone posting that it worked and mentioning a blue screen, so that's why I made a separate thread to hear more in detail if someone got it working and if that includes seeing a blue screen. My suspicion is that the update is flawed and maybe doesn't apply the changes to all the units.

so the first time you did it there was no blue screen? just for science, can you do it few more times with different slider setting and see if you get it again?

So the first time it didn't appear right? Did you notice any change in edge tint that time tje blue screen didn't appear?
That gives me some hope at least , I've tried applying it in Safe Mode but that didn't work either.

The "blue screen" you guys keep mentioning is when the display driver IC itself is reflashed with different calibration values, it isn't just slapping a software overlay.
My edges are fine, but just as a test, I set them warmer and the phone displayed the blue screen as expected, and the edges became warmer, I set it back and the same happened.

the problem is, only few people get that screen on reboot hence no edge color changes are observed.

No, no blue screen the first time, IIRC. Again, I really didn't pay that much attention, but I may have done the process a second time as I didn't notice either much change or a change that I was happy with the first time. But, it did definitely change the edge "tinting", and I then switched back to amoled cinema from adaptive, so perhaps moot.

Screen ghosting/ image Retention

So, I am 1 unlucky in 1000 who has a tianma lcd panel and facing screen ghosting since one month after buying the Note 7. Is there any software fix for this? I heard Redmi note 4x has similar issue. It doesn't affect performence but unpleasing to the eyes. I am not looking forward to replace the lcd as the phone us still brand new. It is imported, so there’s no way to return it. Thanks in advance.

Same thing is happening to me, sadly... Don't think there's a way to solve this through software, as it's a hardware issue

Bought Redmi Note 7S (Lavander) Onyx Black 4GB/64GB Yesterday , Faced Touch Ghosting.
Edit : Requested For Replacement * From Flipkart.

Actually, I did a little goof. Turns out I have a BOE panel instead of Tianma which is good, but even on that panel, I still get some ghosting... so I can't imagine how bad it must be for the worst panels Guess that's what you get when you cheap out on a phone

Wouldn't I need to pay for the replacement? Or if covered under warranty as it's a manufacturing issue?

So basicly even if you replace the phone under warranty, you will get the same panel and the ghost screen will be there again after some use?

you can use this tips to modify the display color a little, to minimize the ghosting effect.
I have tianma with pretty nasty retention, and modifying the display kcal does the job.
**You need use custom kernel with kernel manager or simply a LOS-based ROM to apply this mod.

I have tianma, everything just looked fine, this is only "things" , not she or he , so for me just use it

Fix for now
I thought I was the only one. Bought this device from China and started having this issue after around 4 months.
The problem does not occur with pitch black wallpaper.
I did some research and found this app (Ghost screen).
It's not in play store.

Solution in Pixel Experience Rom
I found a workaround in the pixel experience rom without any apps .
Go to Settings > Display > Live display > Colour Calibration > and set all 3 values to 92.

Weird. I have a Tianma display, yet I am not experiencing any noticeable ghosting. Maybe your screen is faulty.
