Screen retention is a result of using cheap LCD panel. I didn't face it on Poco (or probably didn't notice it yet), but I had it on Mi A1 and it kept becoming more visible with time and I had to sell the device off as the service center didn't admit the issue to be hardware related and kept calling it a software related issue and kept flashing the fastboot ROM.

How could you LG??

What's up everyone, loving this k one but how about that screen bleed though!? Yes I know there is a similar post about this, but I want to make it only about the screen bleed issue and anyone experiencing same? I am about to go get my third exchange in less than ten days
I just checked and the only noticeable bleed I noticed was by the top left of the second screen but it's small. Main screen seems ok, to me at least.

That's true, and for me it's fairly noticable on the top left, along with under the two front facing cameras there is bleed as well for me. This is my second phone.
Could be like the g2x lol
It's definitely there in the top left corner, but there's no way it would bother me enough to go exchange it.
Same here, if only there was a way to invert the color from BLACK text on White backgroud, to WHITE Text on Black Background. The fade would not be noticeable.
I went through 2 V10s and ended up returning both and going back to my M8. Basically what I noticed was slot of backlight/screenbleed issues when in immersive mode of an app. Like a book reader for example. If the background color is white, up at the top of the screen there would be a gray/black hue leaking through.
Of course once you notice it, you see it in other applications that go into immersive mode. I think there is something happening where the 2 displays meet at the top when immersive mode kicks in.
It's mostly only noticeable when the screen is like 60% brightness or less.
Unfortunately that was a deal breaker for me, even though the rest of the phone was great.
What sucks is that I'm going to have to fight a restocking fee for this problem even though t-mobile store reps saw the problem as well

I was thinking in maybe doing the same but getting maybe the HTC m9 or anything other than the Samsungs. Hate them. I will be going today to get my third new exchange since I still have seven more days left. Gets very annoying all this screen bleed issues. This phone is so beast in all other aspects. Camera, sound quality, and love the software but not as much to stock like nexus line.
I have a post here with dead pixels issues, the replacement T-Mo sent me not only had dead pixels as well, but a terrible bleed where the two displays meet. It is only noticeable when you look at the display from an angle, for example phone on the table and you have a light background you see a dark spot there, once I noticed that its driving me crazy. LG quality control is a POS IMO. This phone rocks, but is plagued by stupid QC issues.
There is nothing you can do. All phones will have the "second screen bleed" due to how it's designed.
There are two backlights. First is the normal backlight that lights up the entire display (there is no "second screen" - it's a single LCD panel). Then, there's the secondary backlight - a single white LED on the left edge of the "second screen." This single secondary backlight LED is injecting light through the left edge of the second screen and is not attached to the main backlight diffuser, which is why it lights the screen so unevenly. There are certain times when that secondary LED is on and when it is off. When it is on, it adds extra light near the left edge of the screen, which makes the notifications in that area brighter.
Try this. Turn on the Camera app and observe the buttons that appear on the second screen. Notice that the left-most (or bottom, if you hold it horizontally) button is NOT brighter at all? That's because the second backlight turns off when the camera app is running, and you only see the main screen backlight, which is even. Exit the camera app and you'll see the second backlight turn on and the bleed return. Open the camera app again and you'll see the bleed disappear, as the second backlight turns off.
Do another test. Hold the phone at an angle so the bleed from the second backlight is clearly visible, then go into the settings for the second screen, and turn it off while watching the left-most edge of the second screen - you'll see the "bleed" suddenly disappear, because the secondary backlight turns off (even though the main backlight is on). Turn the second screen back on while watching the left edge, and you'll see the bleed come back as the secondary backlight turns back on.
Yet another way to see it - power off the phone, then power it on while watching the left edge of the second screen. During initial boot, it will look perfectly even, no bleed, because the secondary backlight is off. But half-way through the boot process, the secondary backlight turns on, and you see "bleed."
Now, when the main screen is off, the ONLY thing lighting the second screen is the secondary backlight, so ALL you see is bleed (since the main backlight is off) which looks horrible.
The reason you don't see bleed at all in TWRP is because TWRP doesn't know that there is a second backlight and therefore it doesn't turn it on, since it doesn't know how.
To get rid of the "brighter left side" problem when the main screen is on, all LG has to do is issue a software update that turns off the secondary backlight when the main screen is on - I'm surprised they overlooked this obvious problem.
And here's the kicker - you know why you don't see the second screen bleed on the demo units in stores? Because the Retail Mode app turns the secondary backlight off, just like the camera app.
here's my issue, called again to T/mo and they're sending another RMA..Apart from that am having a defective proximity sensor...will update when the "new" phone arrive
That's not screen bleed. That's where the edge of the lcd panel meets the edge of the bezel around the front facing cameras. It's an unavoidable shadow.
I'm really picky about my phones, especially the screens, but I think you're honestly expecting the impossible. They can't NOT make a shadow there, given the arrangement of the secondary screen backlight and the camera bezel.
If that's your biggest complaint about this phone and the screen, then I think you're being too picky.

I know am picky, we all should be with a $600+ smartphone, in the highest end gamma quality control must be precise. Apart from that I already posted a dead pixels thread and this one has dead pixels too...take a magnifying glass crank the brightness to 100% and watch very carefully in a dark, this is my second V10 and a third is on the way
Now dead Pixels are not acceptable. But that shadow will always be there no how many times you exchange it.

That shadow was not there on the last phone and its really annoying cause it distorts any solid color that's displayed there, also it's only a "shadow" with light content, it's a bright spot with dark content. It looks worse in real life than it does in pictures

That means our models r very radically different.
way much more of an extent than I have been realizing.
Or...u have an adware prob or it's hidden
I think when it comes down to basics...each flavor has it's own heart.
Yet..No matter the carrier and especially when it's a basic LG/LGE setting....it shuld b on all.
Forgive my lack of correct wording....
I bet if u can't see it ..the ..invert....setting maybe just hidden
Again...u r stock?
K now i think....
You should Try searching for "invert" with QuickShortcutMaker app https://play.google.com/store/apps/...G6PnXP4eFRw4Tw9vg&sig2=ujB0W4bySmI1c5Qzvof0KA
No I'm not pushing the app...I'm hoping it may enabling u to see the setting.

You need to take use of their 3 RMA in 90 day policy and switch out from the V10 than.

Lg G5 Screen Issues?

A number of reviewers have noted serious issues with the ips lcd panel on the lg g5, specifically backlight bleeding and "blooming" (when pressure from touching the screen causes distortion). Has anyone else out there with the g5 experienced these issues? If so, will you try to return and get a replacement?
Have noticed neither of these problems. I don't ever run 100% brightness on the screen, then switch to a black background and go into a bathroom and view the screen. And, I don't press the screen hard enough to cause distortion. If you don't do these things, you will never notice an issue.

There is clearly a problem more or less with some units ( bleeding light).
And you don't need to push hard to cause distortion.
I have a very strangle faint vertical line on the right side. Not visible with a black background but looks almost blue-ish on a white background. Like a line of a very light shadow.
I've seen this issue too, but not enough to bother me. I didn't notice it with my phone until i read this post.
I think it's due to the design and battery placement. I think there's a very small gap between the battery and the screen, where the LCD is practically floating and when you put pressure on the phone, the screen deflects a bit until it makes contact with the battery. Otherwise, the battery would get scratched up if that gap wasn't there.
Yes, I have a 2nd G5 and it has the same vertical shadow, except much fainter. I wouldn't of noticed this new one if it wasn't for my first phone being so prominent.
Haven't checked for light bleed, but no bloom issues with finger presses whatsoever. I pushed as hard as I was comfortable on several locations and nothing. Also no shadow that I can make out and I am very sensitive to that kind of thing, especially if I'm looking for it.

I tried swapping out the battery & bottom-chin-thing between my two phones and now my original first phone that had the worse 'shadow line' has improved a little bit. So there's definitely a fault between the contacts that's causing this effect.
It just seems like such a mixed bag in terms of quality control Kills me too, since I've been super stoked for this device since MWC

I'm not completely sure what you mean by fault between the contacts, but i think the issue is due to very small and minute variance in battery shape or size. This variance is probably causing different pressure points on the bottom of the LCD screen causing the shadow.

Personally, I wouldn't call it bad quality control, but rather mechanical and structural design limitations with the materials currently available for use. The thickness of the G5 is only 7.7mm (0.303 inches), that's pretty incredible with a phone that has a removable battery. By comparison the Galaxy s7, is 7.9mm (0.311 inches).
I maybe speaking out of line here, but from an engineering point of view, I am impressed with the design. I am a little worried about the battery swelling up crowning the screen, but i guess i can change the battery if that happens. I've had some battery well up a little in the past...
I've had the phone for 5 days and the more i use it, the more i like it. Believe me, i'm looking for every reason to hate the phone while i still have 8 days to return it if i wanted to. After that, i'm stuck with it for two years.
I don't have any technical knowledge with this stuff but just thought perhaps there's some kind of interference or feedback happening near those plugs next to the battery inside that's causing it like when you hold a magnet up to an old tv.
The battery of my last two phones (Droid Maxx & Galaxy S5) both swelled up which is why I went with the only phone that offers a replaceable battery
FYI, I have a small magnet attached to the battery for my wizgear phone holder in my car. No issues with the screen when I press hard. There is definitely an interference fit now sliding the battery out, but it's not causing any issues.

I'm pretty sure a swollen battery in a G5 will absolutely destroy the phone.

Ditto. The issues AP and others have reported, I've not seen at all. My only real complaint is not being able to do tap to focus reliably on the camera.
I have the led bleed issue, but now I also have image burn in as well. you can see a faint update popup box and notification bar on the screen.
I'm assuming the phone updated last night, and when it finished, it never turned the screen off and left me with what I'm hoping isn't a permanent reminder of the update pop up ghosted on my screen.
LCDs don't burn in. If you have anything it is image persistence. Leaving the screen off for a bit (like overnight) and should clear itself.

I'm noticing it's going away on it's own by keeping the screen off, so you're right it isn't a burn in. thank you for informing me. I'm still getting it replaced however due to the backlight bleed.
A coworker of mine was given a G5 as part of an advocacy program. Within 3 days of getting the phone before the actual launch day, half the screen was unresponsive. We turned it off and next thing we saw was half the screen was showing the home screen, and the other half was stuck on the LG startup. Seems the G5 is having the same issue that LG recalled the G4 for.

I agree, i wouldn't call tap to focus a 100%, but one of my favorite futures with the camera, is the manual focus. I think that for me that makes up for it. Do you know if the s7 has manual focus?
ive noticed this im on my 4th phone from att. I love the phone but i cant deal with it it bothers me too much. i will be returning it soon.

Uneven black levels

Anyone else having this issue? When I switch to the dark mode it's obvious the black level from one corner to the other is not the same.
A black saturation test clearly shows the bottom row visible when the device is rotated one way and then not visible the other way.
Anyone else getting this? I'm going to ask for a replacement.

Damn, that's almost exactly the same.
I just got a full refund for mine as the shop I bought it from had no stock for a replacement. Another one on the way from another retailer, hoping the display is in better shape.
The quality control on these appears to be a bit crap.
OneUI uses dark grey on the Tab S and Note10... There are many, if not infinite variations of grey that approach black. I do art, so it's easy to notice that #000000 was substituted.
SD_black is black, OneUI simply has a dark mode. Also black cannot be uneven on OLED, because black refers to an off state.

You're just splitting hairs.
Black can appear uneven on defective OLED displays. If you use a black saturation or black clipping test you can clearly see with the tablet or phone rotated one way that the bottom row is barely visible (which is normal), but rotate it another way and suddenly they're all clearly visible, they're only visible because that part of display is defective.
I have OneUI on my phone as well, there is no visible banding and black/gray levels (whatever you want to call them) are uniform. If you're seeing any variation then you got a bad display and you should get it replaced.
Similar here. But mainly noticeable in very low brightness especially with night mode on
With which app do you test it?

Display tester, first match on the play store. Find the black saturation test
Or you can use something like the below, loads of similar tests available on the Play Store or online.
https://www.avforums.com/threads/ho...el-on-oled.2204710/#lg=thread-2204710&slide=0
Replacement arrived today and it's even worse than the first one, instead of one corner it's right down the centre of the display.
Also found an easier way to highlight the issue, using the image tester select the burn in test and move all the sliders to the left, this should give you black. Then slowly move the green slider over, you'll notice some parts of the display become green when the rest remains black, at least up-to a certain point. Took the image below in good lighting.
The Amoled lottery. I had to go through many returns before I got a Tab S3 that didn't have unacceptable display uniformity and things don't seem to have improved a lot since then.
I guess that it's cheaper for Samsung to deal with the returns of customers who notice and care about this than simply having better quality control in the first place. Reviewers of course get cherry-picked samples so the quality of the display can be praised to high heaven.
Really makes me think twice about even considering upgrading though...

you can even see it on on xda black theme.
But since this is a common issue maybe manufacturing level, I rather leave it like this, because I do not want to end up with an even worse one.

hi
hours ago i found that when a blank tab is opened in samsung internet (i am using dark mode in system as well as the samsung browser) i could see the uneven black on the screen. i tried to rotate it but still the uneven black was there on the left and right hand sides in landscape mode, and on the top and bottom after i rotated it. so it should not be the ui or one ui problem
i remembered i have read this post so i revisit it and found many of you have the same problem. when i bought this tablet i have check via *#0*# to see how the black was and it's perfect. i also checked with *#0*# before replying to this post and the black was perfect too!
i am too wondering what could be the problem. i think it could be the dark mode which does not use true black (pixel off) in fact

Yeah, It's not the dark mode, this issue effects everything.
If it was just One UI I could ignore it, but sadly it's not. Essentially you have different parts of the display clipping at different black levels, even the sections that are relatively good still look patchy.
Samsung screwed us all but it's OK because it's not a popular product so nobody cares, prime example of how useless reviewers are as well because none of them picked up on it, cherry picked parts from Samsung probably.

Screen test comparison

So I did a screen test using Four fingers multi-touch. The first one is my old Op3T showing all four traces clearly. The second is my Poco showing first two fingers (to touch screen) clearly and other two are faint lines.
Both phones running same android 10 ROM setup and latest firmware. Tried different ROMs on Poco, same issue. Any ideas?
Yep
Happened with me too
Compared it with OnePlus 7T though
Btw Am having Nvt panel on my poco
I'm having no such issues on my Poco.
I've seen a lot of threads regarding Poco display. From day one to now I haven't faced any issues with poco like low sound, poor network, light bleed etc.
However I do have one issue that is image retention. If I am on a website with static fixed colors and I open an app with white screen, the previous page can be seen. But this is only temporary and goes away after 15 seconds.

I'm on CR custom rom, but actually all my gestures are disabled. The issue isn't ghost touch, i dont have it. For daily use it's fine.
It's just the quality of touch screen as seen on the screen test in OP is sub par.

Since its LCD there's no option (nor needed) to have Live Display or Ambient Display. The image retention began about two months ago. It is not consistent. Sometimes the image retains for about 5 seconds, sometimes there's no retention at all. Since this is LCD I don't need to worry about burn in. And even if burn in is possible on LCD I frequently move the UI in different places.
I have a 2013 Moto X as well as a Moto G
I have compared the panels from those phones with my Poco and I see no problems at all. All touches are fine and there is no ghost clicks.
Almsket every day there is a new post about display issues... I guess I'm just lucky to be in the few who don't have any problems.

POCO F1 image retention or LCD burnout on MIUI stock ROM please help.

Hi there, I am using 6/64 GB variant POCO F1 for one and a half years recently I noticed problem like screen burning, on my display. If I use any app for 5 to 10 mins I see a shadow of the same app for 20-30 mins behind the screen. It is more clearly visible in dark mode or dark grey background.
Is there, anyone facing the same issue or knows whether it is a software issue or there is something wrong with the LCD panel? And if its a hardware issue where in India can I change my LCD panel for a good price with good quality?
I posting the Pictures of Screen shadow below, please check it out.

It's a hardware issue. Have an issue like that too. It happens intermittently, but isn't really an issue for me anyway because when I switch to another app it's not too noticeable. Usually happens when I read manga since the screen is mostly white, then there's artifacts for a while then is barely noticeable.
As to where you can get it fixed in your country, sorry I'm not from India so I don't know. But if there's a Xiaomi store/service center they should be able to help you
You can greatly reduce that effect on stock MIUI by going to Display > Color Scheme and change it from Automatic to Standard. Been having the same issue for about 8 months (my device is 18 months old), other than that, haven't had any other display problems, so there isn't much of a reason to replace the lcd pannel (unless you're still under warranty).
Had the same issue with a replacement screen, but after some time i decided that it bothered me too much, so i decided to replace the screen again, and now everything is fine.
