2nd Screen back light bleed like the V10? Screen ghosting/burn?

Hello, now that the Note 7 is dead the V20 is my best option here. I am worried about back light bleed from the 2nd screen and screen ghosting on the V20 I Had very bad screen ghosting with the V10 especially when playing games. I would even get screen ghosting while being on the home screen the status bar and navigation keys would ghost into the display for a long time. I always had my brightness below 20% and this still happened. Does anyone think these issues will be present with the V20?

As an educated guess I don't think it's going to be an issue, but we really won't know until people get their hands on these awesome devices...

cant remember who, but a reviewer on youtube running the preproduction model said there was light bleed from the second screen and around the bottom as well. who knows.

I just watched it about 30 mins ago. It's the Android Headlines "LG V20 Full Review." Hopefully just some preproduction units have that issue...

I have a production North American unit, I see a very very slight light bleed on the top left of the screen. Doesn't bother me and only saw it when I looked for it.

Do you see screen burn/ghosting when playing a game for a extended period of time?

Haven't used it for long enough, but not that I am aware of so far.

i got the LG V20 (F800K) and i cant tell any ghosting or bleeding. but i guess time will tell, I'm currently happy with the phone.

no ghosting after running a few benchmarks back to back, reboot, run again on my new v20.
I concur with the V10 screen issue, my v10 has really bad ghosting
I do have slight bleeding in the second screen lower left corner (only visible in a dark room though) on my v20

I was looking for some info what it might be that im starting to notice as apps change maybe we can chime in now that it been a year. I forsure get ghosting from my home screen to others and back. Yes there is definite bleed from the second screen. I just ran the LCD test and during a few of the color test i see my status bar and the out line from the calendar app i use as a home page. I keep my screen on all the time and run about 50% brightness with the comfort view on high.

V20 screen burn?

Probably a stupid question but - is screen burn as much of a problem on V20 screen as the Samsung Note amoled screens? All our notes have bad screen burn in.

No. LCDs are hard to get image retention. An example would be a status screen for equipment that needs to be continually monitored and has a static image often or all the time. I wouldn't sweat it. These are smartphones and if you're using it daily and repurposed for something else where screen is on all the time and same or mostly same image you should be fine.
But for example if you left secondary screen on all the time with a signature or something it could be possible, but supposedly it turns off when put in pocket.

I leave mine on my windshield mount turned on all day at work.

The V10 had some pretty hefty image retention on two of the ones I owned. I used to turn brightness up all the way all the time and suspect that's why..

Yes, my first V10 did to, but once you let the screen turn off fire for a couple of minutes it would go away. My second V10 had no retention at all and neither does my v20

i do have v20, image retention / ghost image / screen burn, whatever they call it. it shows on my phone status bar.

I think thats just a software glitch, not hardware burn like on every samsung I've owned or seen.

Seen quite a few demo models at carrier stores while I was playing around with the V20 before buying 1 and not a single one had any of those issues like most of the demo units with AMOLEDs. That's just my experience though

I have had image retention a few times. At first I thought it was burned in. It seems to only do it to me with Facebook in landscape mode. Scared me at first.

No, an LED screens main advantage is it doesn't burn in unlike AMOLEDs, but it uses a **** ton of battery as you know. It would be very hard to burn in a V20, and even if you did get some, one of those apps would remove it, where it won't remove it on an AMOLED.

uneven screen backlight...anyone?

Hi guys,
Anyone else notice any uneven screen backlighting? I read forums on the v20, and when reading back text on white background - while scrolling down to read more text I notice dark shades on the screen. I downloaded screen test and lo and behold...dark patch on my screen! I then sent it back to LG and assured me that they replaced the screen module and tested it and all 'voltage' was normal - BUT, dark shades were still present albeit in a different spot!
Can someone here please confirm if this is a normal thing for LG screen as I realise it is LCD backlit and not OLED hence a few bleeding / inconsistency of backlight would be present. Even though I have never experienced this on ANY of my HTC's which were all LCD screens.
cheers guys! sorry for the long post!

Yes, i have it too! H910 variant. Two dark/dim spots that run horizontal from edge to edge. Can be more noticeable/annoying in landscape view than portrait actually.
Exchanged one brand new H910 for another. Same problem. Both manufactured 12/16. Havent had this on any other LG Ive owned (RS988 G5, D850 G3, P930 Nitro HD) or Moto for that matter. Pretty bummed to have this in an $830 USD device.
Edit...seems like the issue can be excaberated by different viewing angles. Also, totally anecdotal, but i looked at my display at a stoplight (wearing polarized shades) and i noticed the screen looked unaffected by the shades compared to other LCDs (cars TFT nav screen, an eIPS tablet, etc) that i have in the car. Wonder if what we are seeing is some type of side effect from a polarizing filter, or maybe lack of, used with this display/panel?
Or, maybe these things are edge-lit and LG used an uneven arrangement of emitters. Not really sure.

Good call...I do think it may be the backlight being edge lit! which could only mean (maybe) the backlight has failed at some spots or LG engineers mis-formulated where to put the lighting. it is very sad to hear that this may not be an isolated problem.
I did however sent it back for repair and the technician advice of a NEW LCD module/screen fitted. was sent back to me the same day!! WOW! BUT...same problem but it a different spot.
If this keeps going I may have to consider a new device altogether!
Then im starting to hear crackling on both earpiece and speakers....but thats a different thread!
arrgg...

I began to notice this on my v20 that I bought at the end of December, at first I thought it was just viewing angle or I messed up the screen. However my mom just got a v20 and hers' has the exact same problem in nearly the same spot. I should add that my phone is an LS997 that is completely stock. Also @D0NZ which screen test application did you use to see the problem better?

I used an app called full screen test...its free and simple. I then took a photo of it with my old htc m8 then sent it to lg for review.

The V10s have this as well. Something to do with the backlight and 2nd screen. Kind of got used to it on my V10. Was hoping that would have been addressed with the build of the V20.

I think so. On the V10 it was really noticeable when the main screen went into immersive mode and the 2nd screen went off.

this to me is a deal breaker! I read a lot on my phone, tis why I got a large screen! If this is the 'norm' for a flagship...
I pretty much think its unacceptable. They produce their own screens and cant get a flagship right? hmm...which phone to replace it with now that is available locally (for me that is down under)

So here are some pics I sent LG originally!

Looking at your grey screen, those bands/dim areas are in the exact same locations on my device (and my prior V20)! It must be inherent to this panel. You said the bands/dim locations changed after LG swapped screens/devices for you though?
Either way, it is a bummer. I'm still undecided if I should return mine as well, or just live with it. Almost every recent device has some quirk to live with it seems. I recently traded a Samsung Galaxy S7 that had a beautiful AMOLED display, but the device picked up scratches (on the display *and* body) like I've never seen before. I even took a look over at the dark side (Apple), and they seem to be catching flak for overheating and camera problems in some iPhone 7 devices. Sigh.

I have it on one corner pretty bad, is this because of the IPS screen and how the frame of the phone is pressing on it?

I think its to do with backlight distribution tbh. Ive had a number of HTC's and NONE of them had backlight distribution issues. Im now wondering IF a 3rd party screen module would be better than the original LG produced? OR...if this is an isolated issue only on some devices. My device was manufactured Nov 2016. Maybe a later produced model has better screens? Anyone with a newer produced V20 care to share?

I think its the placement of the 2nd screen backlight. Ill try to find the thread. Someone with a V10 explained it last year.

Here is the post I remember from the V10 forums that seem to make the most sense regarding backlight being uneven.
https://forum.xda-developers.com/showpost.php?p=64236798&postcount=45

Both my replacement V20 and original V20 have uneven screen backlighting (at least the replacement has a better back cover mechanism). There is a dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.

^
I think I can live with that...as in...the dim sections are on the edge of the screen. Mine was in the middle of the screen which i cannot stand!
I have sent the replaced screen NOT to LG but to the place where I bought it.
They said that the repairer that LG told me to send it to was the last on their system as 'reliable'. The store said that they will deal with the repairer and LG. I kind of hope the worst happens and they just offer me a refund or a total replacement - but I doubt that would happen!

UPDATE: so i sent it back to jb hifi, on the report, they can replicate the issue. On the repairers report - they couldnt
SO i get it back with all the 'test' that they have done on it being to manufacturer's specs.
Which i think now...was never good to begin with
Too bad i cant unsee what i can see...sux...I wonder if AMOLEDs have these issues? Anyone care to elaborate?

I have this issue with my LG V20 -- only when viewing photos
I have this issue with my LG V20 -- only when viewing photos - see photos -- screen has two long bright lines.
See attached photos - lines are not on the photos themselves --it is just in the backlighting -- and the lines are not there when viewing websites or if testing the screen with an test app. Please cut ans paste links to see photos - remove blank area after http -- I can't post links till I have 10 posts on this site - if any kind poster could repost so others can see them that would be great!

http ://oi68.tinypic.com/331oj0n.jpg

I have the same issue below secondary screen. Only noticeable on white background. Doesn't ruin reading books, it's there, but minor. I have dual sim variant. I'd be very upset if I paid launching price. All those things you only find out when you get the device.

image retention?

So far this has been the best mobile device I have ever owned from Palm, to BlackBerry, Motorola, iPhone, Samsung, Nexus, Asus. This has also been the best OS I have used to date. No lag, no battery drain, no boot loop, and I get a removable battery.
Too many features others lack for the same price with less storage for the same money as the V20.
All that being said there is a problem with this phone that also ocurred with my V10. I keep the screen on at maximum brightness all the time since battery is not an issue with this phone (I have many spare batteries). About 7 months into my V10 I started noticing "ghosting" along the left and right edge of the screen. I use white icons which means I always have a dark wall paper. I could notice a very thin whitish smear along the edges. Its not bleed like you sometimes see on the second screen. What I notice goes away when you turn off the screen a while or you switch to a lighter colored background. Then I started noticing that icons for notifications were beginning to burn into the screen when using a dark background... Very odd because this is almost always an issue with OLED screens and not LCD displays like on the LG phones. Then the screen burn in started occurint on the main screen, typically when a bright image is on the screen for a long time and when switching to a screen image with a dark background the borders of the previous image are still visible on the new image. Once the phone is off for while, again, the retention issue goes away but comes back if the same image is on the screen for more more than 30 seconds or so.
Thankfully This does not affect video playback or video streaming. Its only with digital images, logos, or text.
For those not familiar with this problem its called image retention.
I placed a warranty claim on the V10 and a new phone was sent. I traded in the replacement phone immediatley for the V20. And now only 4 months into ownership the exact same problem is occurring... Grrrreat.
When I called LG about the V10 they had no idea what I was talking about. I pointed out that this issue has been discussed in the forums for the last year.
Are you also seeing this issue?

it will go away its not really screen burn in, lcd's have this issue and its common, turn screen off for 24 hours and let the lcd cool off and the ghosting will go away. The LCD's dont have the same screen burn in that the OLED screen would.. but latent images will occur if your keeping it on non stop and high brightness. IPS at its best.
also try and use the screen burn in app and let it spam the screen with the multi colors overnight, this will help cover the burn in like ghost images.

24 hours? Hmm... I will try 8 hours tops because of obligations I need to be available by phone all the time.
I have had IPS displays before that were on all the time and didnt see this issue before...and I run all my devices into the ground.
My Plasma TV has latency issues, my Samsung AMOLED displays have burn in, Samsung LCDs had vertical banding, this LG IPS display has latency...so which displays are immune from premature (in less than one 12 month) issues?

V10 , V20 , G5's displays ( maybe include G6) are quantum dot IPS so they all meet image retention . Other IPS displays never meet this problem

I noticed this issue on my v20. If the phone remains off for a bit the image goes away. It can be annoying but if it doesn't hurt the phone
Sent from my Nexus 9 using Tapatalk

The screen on the V20 isn't a regular IPS, it's a "quantum dot IPS" which may be more prone to some degree of image retention due to their form of illumination (I don't know a lot about it but it's a kind of atomic luminesence) which supposedly increases colour accuracy and range while lowering the power requirement for for the backlight.
It's possible this might be the root cause of the 'ghosting' but I'm mostly guessing.
Ironic though if QD displays are prone to ghosting, and LG knowingly equipped thier phone with an always-on second screen with that tech.

Yes. I'm on my 2nd replacement for the same issue. The phone I'm typing on is now having it. The screens last anywhere from 6 to 8 months before breaking down.

Glad to see that this isn't only happening to me, I find it super annoying, I never had this happen before on other devices, and it's an unacceptable occurrence that of course nothing will be done about it, I for one can't wait to get rid of the V20.

same thing started happening to my v20 recently, around 4-5 month old phone. it's an annoyance that should happen to a flagship phone, but it looks like we're SOL...

Tilted Pixel lines Problem.
I am also facing same problem with my 3 months old LG V20 Phone.
My phone have one more Problem.
I can see pixel lining (in whole screen) even though it is quad hd display. But the problem is that it is not horizontal, It is tilted 10 degree, and there is no vertical lines that I can recognize . And it is annoying to me.
If the screen is equally pixelated then I should have seen both vertical and horizontal lines of pixel equally like you can see in TV LCD Displays.

I encourage anyone whose 12 month warranty is about to expire to file a claim. And not use the phone at maximum brightness unless outdoors. Luckily I had some other issues with the phone like NFC and the speaker being somewhat distorted and the phone was replaced for those issues as well. If you see any deterioration in any other hardware aspect of your V20 you should definitely file a warranty claim.
I plan to keep this warranty replacement for another year as the only phone with the image quality I like is the Sony Experia XZ Premium which doesn't work with Verizon. Believe it or not I compared the V20 to virtually every new OLED flagship anr they all had a dingy yellowy color compared to the V20, including the new iPhone X. The Sony was the only phone that had both the color accuracy like and LCD but the deep color pop of an OLED. Best of both worlds with the only 4K screen and battery life better than my V20

It is my understanding that the V20 will get image retention, but not actually burn-in. Is this true?
Also, I have searched for solutions to the image retention problem. Most solutions advise the use of apps that cycle through colors or simply leaving the device off for awhile. I used a color cycle app, which helped, but the issue returns. And leaving my device off is, simply put, not an option. I did come across a post about replacing the thermal paste. Any truth to this method?
But I'm wondering, if I go through with taking my phone apart to apply paste, wouldn't it be beneficial to also replace the screen as well? Or am I missing some factor I haven't read about yet?

Once image retention sets in it will return once the screen is on for long enough. I ran those screen burn in apps overnight for months. Made no difference at all. The only option is to completely replace the display if you can get it cheap.

No need to do all that, install Night Screen by paper airplane dev team and set the slider at around 80%(make sure you're on the moon icon). Also let the screen cool off before you do this and set it up. You won't really notice the filter much and all the retention problems will be a thing of the pass.

@porscheoscar - No kidding lol Replacement LCD are not cheap. I'm gonna keep an eye on them cause I want to keep my V20 as long as possible. One of the last phones, that I'm aware of, I can carry an extra battery for. I love switching batteries while my friends with their latest, greatest phones watch their battery percentage like a hawk hehe
@salvichulo - Thanks for the tip ^_^ I installed it & am giving it a workout. I try not to be on my phone a lot, but I'm a gamer ;P Once phones became powerful enough to really game on, I killed my Xbox Live account & game exclusively on my phone. When I get the money I'm gonna look into getting an Android Emulator for my laptop.

A bunch of people are on here saying that they notice this ghosting problem after a few months, and that after that their phone's screen deteriorates rapidly. I just got this phone for Christmas, and I love it, but I noticed this annoying ghosting problem immediately. Should I be worried? I'm a little nervous it's getting worse.

why don't you root your phone? By rooting your phone you can change color setting by using custom kernel it help you with this problem .

Screen retention purchase question

Hi All,
I know that there are some topics regarding to ghosting/screen retention etc. What about now? Is it still safe on the long run for the users, are you experiencing the screen ghosting like on the G4, G5..??
I want to purchase this phone, but on the G2 i had screen issue.. G3 luckily no issue, G4 burn in/ screen retention, G5 burn in/ screen retention... So can someone give me some advice, is this still a problem on this devices?

No burn in so far. But that usually takes a while for it to show only had mine for 3 or 4 months so far

I had the G5 which had serious issues with screen retention, purple spots when screen was hot, etc.
The G6 does not exhibit any of these.
You can buy it without problems

Exactly, well it is a nice phone and it is 2-4 years proof..

What the hell are you talking about? I have the G2, G4 and now the G6. I don't have any issues like that.

unfortunately even the g6 has that ! but its not as bad as the g6 ! its not even noticeable you can see it only with white colours in certain backgrounds (grey)

It's a common problem for LCDs display, G5 was the worst because display was not perfectly mounted, on G6 there is way less retention

No problems on G6, even after the full day of usage on highest brightness settings. This Quantum Dot display is beautiful btw.

I got the screen retention problem after 2 months of use but it was gone without me doing anything after 10 or 15 days
