Weird LCD Lines, colors, blooming effect - G2 Q&A, Help & Troubleshooting

The video speaks for itself. The phone is a Verizon LG G2 on a replacement screen of what I thought was OEM quality after dropping my phone on it's corner (digitizer went). I went for a white b/c why not change the color while you can! The screen was installed in December and running absolutely perfect until today.
eBay link: http://www.ebay.com/itm/171165308218 I've contacted them about it but of course who knows if they will replace it. Just wanted people to be aware of the situation. Not sure why the screen would work perfectly for a few months then just die...

Yellow screen on 8525.

Well I got a "refurb" 8525 from ATT and it was sweet. Until the screen stopped responding to touch. So I had ATT send me another(at my charge first). Well the second one arrived quite quickly but it has the obvious yellow(pee'd on) looking screen. Next to my other 8525 the difference it very obvious. To me anyway. My broke 8525 has white whites. Whereas my replacement one has a yellowish white. I'm kind of miffed about it. I think I'm going to call and have them replace it one more time and see what happens. If I get another yellowish screen I guess I'll have to deal with it. Also I notice the speaker on the replacement is "louder" but more "muffled". Strange. I used the same Black rom on both units so there shouldn't have been any differences software wise.
Anyone else experience this? I'm thinking that maybe my replacement had a cracked screen and they replaced the screen with a lesser quality one...?

Slight Screen Discoloration

I've noticed some slight screen discoloration on my LG G2. The discoloration is about half way down on the left side of the screen. It's a very slight yellow crescent shape of discoloration. It looks similar to the discoloration my iPhone 4 experienced. Has anyone seen this issue with the G2 screens?
I contacted Verizon and they are overnighting me a warranty replacement. They also reached out to LG, who claimed this is not a known issue with the device. I just wanted to make you guys aware, as well as see if anyone else has experienced this. I'm not too familiar with LCD technology, what could be causing this discoloration?
Unfortunately I cannot post pictures because I am a new member, but I wish I was able to show you all what I'm talking about. It is VERY minor, however, I can still see it an it is bothersome to me. I figured I should have it replaced considering it's no charge to me and I don't want it spread... if that's even possible?
I'm starting to question whether or not I want to accept the most likely refurbished phone Verizon is sending me. It seems the yellow has faded slightly, although it becomes more present when the screen is on for longer periods of time. I guess I just have an irrational fear of getting refurbished electronics, like there's going to be something wrong with it or it'll develop problems down the line. I guess I should just take the refurbished phone and call it good enough, this way I don't keep looking for the yellow discoloration every time I use my phone... yea, I'm that neurotic about perfection.
Screen Discoloration
My LG G2 has a similar discoloration, orange in color, on the right edge near the top. I have a replacement on the way.
I don't have a screen protector or a case on my phone. No water/moisture exposure, no drops, no extreme temperatures, etc.
Any idea what might be the cause?
I've got the exact same problem I tried seeing if doing a normal restart of the phone would help which hasn't and it doesn't appear in screenshots and it's also happened recently about 1/2 way down
I'm on my third G2 (in 9 months) with this problem. Few of the staff in the Verizon stores have ever seen or heard of this problem.
I'm probably going to change to a different phone.

Inspect your edge

A lot if people have been received their S6 Edge phones with defects, either through transit or manufacturing, I am now on my third one in 3 days due to there being a small chip out of the metal trim under the screen and then the earpiece speaker being all fuzzy on the replacement, not to mention one of the others i was offered had a chip out of the metal surround. Luckily my third one now seems perfect (fingers crossed).
Just make sure your phone is perfect before you walk away at the end of the day your paying a lot of money for it and its gonna save you going back and fourth like iv had to lol
I don't know how it works in other country's but here in the UK carriers HAVE to give you 14 days "cooling off period" which enables you to get on the spot exchanges if your unhappy with your phone, or they have to let you cancle your contract.
Hope this is helpful, thanks.

I can attest to this as I'm about to take the second one back this week. The problem is that it is difficult to do at these stores due to lighting. The first one I return as there was a small (miniscule) circle on the glass, otherwise the phone was perfect (In hindsight I wish I kept that unit). The second unit has a screen that I'm not sure how it made on the phone as it should have been rejected. Top and bottom has green tint, left side had purple tint and top right has the dusty/dirty section that you can clearly see on web browser when reading. Now, the VZW store was extremely nice and agreed to replace my first one with no issues. I'm going back to take the second one back this week.
The issue is with lighting at store and everything is cranked up. Tough to see screen issues on that type of brightness. I can't stand screens that aren't uniform and calibrated, and after reading about Amoled this weekend, I'm not expecting much. I'm hoping third time is the charm, but in all honesty I may just give up on this phone, as I don't really have the time to go back and forth to store every week to play the exchange lottery.
definitely no hardware problems here..
I smell what you're cooking! Typical company issues
Anyways, got mine S6 EDGE and I'm in love with it. I did not check everything, but it seems to be fine. But I have a question for you :
It is normal that the speakers are a little bit (I don't know how to describe this)...rustled, when I have the uppermost volume?
After reading this I thoroughly inspected mine. I guess I got lucky. Verizon 64GB White one and I don't see any issues at all. Sorry to hear you guys are running into issues though :/
T-Mobile 64GB Sapphire BLUE here. As far as I can tell, no defects. It almost sounds like initial batches had/has all the issues, but that's a small sample size. Personally haven't run into any thing related to: straight-from-box screen scratches, screen rotation issues, or color variances.
Only thing I wish it had was a little less sensitivity right above the home button... I keep hitting the area on top of the home button first, and then the button itself.
As for the speaker quality Its hard to tell really because it could be your cell connection affecting the sound quality as well, the problem I had was that no matter who I called it sounded like there with something going "zzzzzttz" "zzttz" as they spoke! As far as I'm aware the sound quality is actually pretty good cranked up full!
Come to think of it the first one I was given also had more of a yellow tint to the whites than the one I have now... Maybe a placebo effect but still something worth mentioning!
Btw : I just checked my display, I have a few,little scratches on my display. Is that normal? (You can only see them with bright light)

Depends on what you mean by normal. Around 30% of people here have reported the scratches.
You all should check for screen non-uniformity. A portion of your screen might be pinker than normal.
Here are pictures I took of my screen. I have a sliver of pink tint at the top and some pink tint at the bottom part. Grays also appear brighter at the bottom part of the screen.
Should I have it changed or this is above average for a s-amoled screen?

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.

But I still have that unwanted effect even if the second screen is off?

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!

...and these lines stay the same even when you enlarge the photo...

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.

LG V20 pixels burning into screen.. ?

So.. Just today ive been noticing the remnants of a game or video name being "left" "burnt" (if you will) into the right top to mid side down the ride side of my display.. Any ideas? Has anyone else experianced this? Trying to recreate it but its only doing it very fantly currently.. And barley noticable.. But after i had played my game for a little while earlier i could clearly make out parts of the game remnants on my display..
I get this too but it only shows up on grayish colors and it goes away after about an hour or so. Happens mainly with 2nd screen but it'll do it every now and then on the main one. Brightness seems to affect it's appearance more as well. It shows up more frequently for me when Brightness is @ 90 and up.
same here , i am getting the pixel burn as well. what can i do any suggestion?
I'm getting the same problem, called T-Mobile they're sending me a replacement unit to replace the replacement for the original that was bootlooping.
For all with the problem, I suggest getting LG to repair it since it should be covered under warranty. Also, just thought I'd add that LCD screens don't burn in, like their AMOLED counterparts. I believe you can describe this as ghosting, or just say the pixel is stuck on the same color if a customer service rep asks. I could be wrong, but this is what I've heard for most of my life. Hope that you guys solve your issues and return to a problem free experience!
Guys try a program called Pure Noise 2 and let it work overnight. I never had this issue with my Note 4 but even then I periodically ran the noise program. Let me know if it works!
Residual Image
I have this issue as well. From Google sleuthing I've discovered it is referred to as "Residual Image" and it is not a "burn in". It was said that the lcd tech used by LG has this "characteristic". It does self correct. And, most definitely appears most often with gray backgrounds. After seeing both of my parents s7 Edges AMOLED screen burn in issues, I feel we have the better tech comparatively. yay?
Screen Retention\Ghosting
Same problem.
Is covered under warranty?
Did anyone solved this?
