Only happens if you go into your room in the night with the lights turned off, put the screen in the minimum brightness and with dark grey colours.

i really think all the LG display panels suffer from this but some people aren't testing in the right conditions to check.
[Huawei Mate 20 Pro Questions & Answers] Senjaya:
Huawei Penang Malaysia has offered me a new replacement for my unit. But when I test the screen on the new device, it has the same issues (bleeding on the top side). It was using the same LG panel. So I refuse the replacement and they suggest me to wait until new batch. Thumbs up for Huawei Penang for the effort. In the meantime, I'm using my old unit with the cloudy (bleeding) screen in the middle.
[Huawei Mate 20 Pro Questions & Answers] pyro2677:
ok i just used the OLED tools on both my old 2 weeks since screen replaced S8+ and also my Mate 20 Pro 2 day old.

When the brightness is turned all the way down yeah i can see the colour on the edges where the S8+ doesn't. I haven't noticed it in everyday use I guess I'll have to see how it goes.

Pictures didn't work couldn't see very well as was in pitch black room.
[Huawei Mate 20 Pro Questions & Answers] miloshsk:
Are you in the UK? When did you pre-order and claim? I've claimed 2 weeks ago, no confirmations yet.
[Huawei Mate 20 Pro Questions & Answers] magnatom:
Yes I'm in the UK and made my claim on the 28th October. I'm with Vodafone.
[Huawei Mate 20 Pro Questions & Answers] misiokicio:
I know what ur saying bud, i dont see anything at all, but i am not searching for it, just using the phone as normal , if anything appears with higher brightness then yes, i would return the phone right away, maybe that's how oled panels are, yes agree to some extent like green uniformity at the sides like some reports... That's a shocker,
[Huawei Mate 20 Pro Questions & Answers] vwite:
Yeah your panel is probably a good one, if my phone is fine with auto brightness during the night I'll just keep it but if it looks extremely green on the edges I'll definitely exchange it or return it
[Huawei Mate 20 Pro Questions & Answers] djBarren:
Mine is getting progressively worse. Just finished night shift where I've used it all night, mix of web browsing, Netflix, YouTube and Instagram and a 40W charge.
[Huawei Mate 20 Pro Questions & Answers] riz157:
I've bought mate 20 and find light bleeding at the bottom of the screen, it's terrible and so obvious.

Lovely phone but not going to tolerate this sort of poor quality.
[Huawei Mate 20 Pro Questions & Answers] havokk:
Took a coupe pics of mine last night and it appears to be worse yet this morning
[Huawei Mate 20 Pro Questions & Answers] edward78:
Not true buddy, i compared my mate 20 pro with S9Plus, both in a dark room with the same dark grey wallpaper on.

The mate 20 pro has very uneven screen, showing patches of different grey colour, lighter on top and edges. In the other hand S9Plus has a even screen everywhere.

I didn't noticed first as i wasn't looking for this issue.

If in normal brightness on white wallpaper you will see pink/purple patches/lines then you have a burn in(i had this on a S8 and had screen replaced under warranty).

We should ***** about on huawei twitter /Facebook page, after all we bought their flagship and it was expensive
[Huawei Mate 20 Pro Questions & Answers] Phil750123:
here is my example, pretty uniform apart from bottom left which it doesnt seem to happen as much.

Its only visable at min brightness in darkness, on dark grey backgrounds! Not decided what to do yet, to be honest without reading this thread i would of never of noticed.

Brought from 3 uk and they havent got any stock in anyway so might leave it a few days see if it gets worse.

Plus has anyone actually exchanged and not got the issue, this seems pretty wide spread to me, i assume its an issue with the screen rather than a glue problem.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Damn that last picture says it all. What the hell have they done on these screens to produce such an awful glow.
[Huawei Mate 20 Pro Questions & Answers] Frontfiringspeakers:
What wallpaper have folks used to test this problem?
[Huawei Mate 20 Pro Questions & Answers] Phil750123:
i am using an app called blackscreen, you can change the greyscale and its full screen so seems best.
[Huawei Mate 20 Pro Questions & Answers] havokk:
You can see it on any wallpaper when you drag down the notification bar so it dims it
[Huawei Mate 20 Pro Questions & Answers] wqwave:
I just got the m20pro but does not have such effect. Does it happens after time? Or out of the box issue?
[Huawei Mate 20 Pro Questions & Answers] havokk:
Mine didnt show it at first but it gradually appeared over a few days
[Huawei Mate 20 Pro Questions & Answers] Guitarfreak26:
Yep I can report I have the same issue. Mine was fine at first, suddenly appeared yesterday all down the left side. I purchased it in Twilight from Mobiles.co.uk and now they don't have stock for an exchange. The head of uk customer service Muleya Sialwiindi said it was a one off issue in reply to my email... Clearly not.

Really like the phone but cant unsee the green now and cant get an exchange. Wish id never bothered!
[Huawei Mate 20 Pro Questions & Answers] lynxblaine:
Factory defects can happen, they do happen to every company. Have you tried Huawei UK direct?
[Huawei Mate 20 Pro Questions & Answers] bazda:
I think every single person will notice it after some time. For me it was first device with curved sides,so the first impression was focused on this sides,and i saw more light glowing from them. After 10 days of usage,even in normal light at grey background it was turning into green/yellow. While i was watching series on netflix on fullscreen i could notice that colour was changing on sides and near notch. I hope that swapped device will be better,but after 1 day heavy usage, it starts to glow a bit. I'll keep it for one week.
[Huawei Mate 20 Pro Questions & Answers] Guitarfreak26:
Yeah mine now shows green even on white screens.. was perfect at first
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
So had a call from mobiles.co.uk about arranging a replacement. I've said to call me back in a week to sort so I can arrange a replacement phone for the time being as I'd have to send mine back first for a replacement to be sent out after. Bit annoying but I guess I can deal with that. They also said another batch will be coming soon so hopefully I can get a phone from that 2nd batch to see if it's any different. I'm pretty screwed here though because I paid out my contract with O2 to get this and now I've transferred my number over, I don't think I have the rest of my contract with O2 should I decide to cancel and just wait it out. Sigh. Hoping that soon Huawei will give some sort of statement.

As a side note it's definitely getting worse or more noticeable. I use a grey gboard keyboard and can see the tint now at medium brightness in a lit room. What a farce.
[Huawei Mate 20 Pro Questions & Answers] stewartk:
Got my second phone today from Vodafone. Will test for a few days but I'm guessing its going to do the same
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Keep us updated, it really sucks.
[Huawei Mate 20 Pro Questions & Answers] stuclark:
UK twilight phone from CPW's stock last week - LG screen and so far (day 4) no green bleeding anywhere.

Comparing the screen to my LG V30 (also P-OLED), the whites are far colder, yet the screen tinges towards pink far more at low brightness; so I'm sure something could be done about that with a software change.

...the green bleeding though is definitely an issue - should mine start doing it, it's going straight back for refund.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
If they did you'd be through them directly. Retailers will have no idea
[Huawei Mate 20 Pro Questions & Answers] GrumGrum:
Just FYI mines through Vodafone as well and mine was validated last week, got mine on 26/10. Although replacement is coming tomorrow.
[Huawei Mate 20 Pro Questions & Answers] YoSoyCarlosG:
Same here. Did the test and you can see something, at brightness 2 and 3. From 4 and up it looks very uniform :)

When on dark theme and in phone app, no green on minimum brightness, so thankfully I got a good one!
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
My replacement is coming today from Vodafone UK will update with a new picture when it does, for reference I had a pre-order with an LG screen

Let's not talk about how difficult it is to backup and restore this phone using Mac OS X, iTunes doesn't seem so bad now
[Huawei Mate 20 Pro Questions & Answers] benbird7:
Really feel for you having to get replacement phones due to this green screen issue last thing you want is waiting around to change phones, I purchased mine through Facebook marketplace as an unwanted Vodafone upgrade (phone too big) and whilst it has an LG panel I have not had any issues with the screen. I am however going to keep an eye on it over the next few weeks.
[Huawei Mate 20 Pro Questions & Answers] bronxxxxx:
just received my second replacement from Vodafone uk (twilight).this one also has the LG screen.i'll run some tests later today and give see if it has the same problem.
[Huawei Mate 20 Pro Questions & Answers] Zulliz:
I have been considering buying this phone, since my OnePlus 3 has gotten a tad old and this phone looked great, but im very hesitant because of this problem and i dont wanna go through with having to possibly return it and keep doing that till i get a good one.

So today i asked a colleague which brother is a Huawei sales person to ask him about the problem, funnily enough he had not been informed that there was any issues, but he would Call and ask some people. He then called back and told us that there was a problem with some lg panels, but only 5 defects had been reported in the EU and 0 in Denmark (where i live).

I just find that really funny that they only have 5 reports of it in the EU judging on this thread there should be alot more.

Biggest issue for me with this is that i dont know what phone to get instead? Op6t is fine, i just wanted the m20p camera, wireless charging, design and just overall i wanted something not all of my friends have.

So my second replacement i got form the retailer here in Norway ( Telia ) have now the same problem its slowly truning itself into HULK.

So i contacted huawei in Norway and they will solve this issue by personally meeting me and replacing my phone and making sure this does not happen again. So im hoping for a BOE screen this time ! So huawei is not jerk about this situation even tho its sucks for us users experiencing this.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
So I got my replacement on Friday which was an LG screen. Seemed okay but now seeing it again after about 4 days. Assuming it's going to get worse. Has anyone in the UK had one direct from Huawei?
[Huawei Mate 20 Pro Questions & Answers] djBarren:
Just got my replacement device this evening. Sad to say it's an LG screen and also sad to say it's looking like it's going to go hulk on me.
[Huawei Mate 20 Pro Questions & Answers] Trident10:
I think its ridiculous that huawei didnt said anything about this yet.
[Huawei Mate 20 Pro Questions & Answers] jordand77:
Got my replacement today too. LG again, out of the box the lower part of the panel is looking green - when in a dark room with low brightness... Note that my first device didn't develop the green screen Issue until 12 days....

Do we have any other news on BOE screens? I recall there was a post or 2 a few days ago where BOE users also had the green issue...
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
Got my replacement, here is the difference:

[IMG="a"]https://image.ibb.co/esaRDV/Image-12-11-2018-at-23-16.jpg[/IMG]

It's an improvement on before, but still slightly greenish at the bottom.

LG again
[Huawei Mate 20 Pro Questions & Answers] bronxxxxx:
i'm exactly in the same boat.received my 3rd replacement phone today and its exactly like yours.an improvement but still...
[Huawei Mate 20 Pro Questions & Answers] RabidWolve:
Agreed.

Also alot of websites still have not reported the Green Screen issue.

Android Authority one of the major sites being one of them. Instead promoting the Mate 20 features and

Deals.

A disgrace all round.

How long u had it for now?
[Huawei Mate 20 Pro Questions & Answers] leo72793:
I fought clove AND WON. I got them to cover the friggin shipping, which was all i asked for to begin with! Now they did it, probably thinking im going to accept a replacement, which i refuse. i will not deal with a company this disrespectful to its consumers AFTER a product has issues, they go completely ghost. Went from a few emails a day to one every 3-4 days! and then none at all.

The M20P is boxed and going back tomorrow. I will be informing them that IF i do not have a refund within 24 hours of receiving it, ill act on the claim. Im not playing with them. Its been over 10 days of trying to RETURN this phone with them. It should be there thursday night while i am asleep, and i should have a refund FRIDAY.

Do not settle people. Fight til you get the right outcome! we are the consumer, NOT the responsible one for defective items!
[Huawei Mate 20 Pro Questions & Answers] mrljina:
I have bought Mate 20 pro in preorder (24th October) in a store in my country (Croaita), I took blue with a gift (wireless charger and a NM card). During purchase delivery date was November 7th, but shortly after paying the phone, they contacted me with info that delivery will be in second half of November (they explained they were notified by importer...). Contacted today the store and they explained me they have black and twilight if I want any of those two, but I declined with explanation that I want a blue one. I read all posts from first till last and now I'm in a bit of an agony because what to expect from it and what is the solution considering all those problems through your providers and services???

I'll continue to follow the thread and of course when I get the phone post any future **** with it...
[Huawei Mate 20 Pro Questions & Answers] leo72793:
The blue is not really released so it may have fixes done to it. Hope for it. Just want a uniform screen. I may wait a few weeks to get another

After 4 days with my Canadian twilight LG screen I now have a complete green bleed down the right side and top. It wasn't there when I did my uniformity test out of the box. Guess I will see how Telus handles it. It's clearly a widespread problem around the globe
[Huawei Mate 20 Pro Questions & Answers] RivAngE:
2 out 2 phones with the same problem so far, I'm thinking to either go for the Samsung equivalent or wait for P30... Since Huawei is in denial mode I don't expect my problem to be solved, they might have sent only LG screens in Greece.
[Huawei Mate 20 Pro Questions & Answers] Phjodor:
How did you convince them to do that? When I talked them they said that the only solution is that I should talk to Mobylife and get it sent to service.
[Huawei Mate 20 Pro Questions & Answers] Orabas:
Hi, I followed this post actively before deciding to order my m20p and wanted to share my experience.

For those who are interested, I ordered an emerald green one from carphone warehouse on O2 and it came with a BOE screen. So far no issues. Can't say if that was luck or just what carphone warehouse have in stock so use that info at your own risk :)
[Huawei Mate 20 Pro Questions & Answers] E36coupe:
Just get a Note 9 and be done with it. Far better phone than the Mate 20 pro. The only things you'll lose are the IR blaster and the flakey in-screen fingerprint sensor. The Note 9 camera is better and Samsung experience has less glitches and is much nicer to use than EMUI, and will be better still when Pie launches on the Note in January. Huawei have shown their true colours with this and it's appalling the way it's been handled.
[Huawei Mate 20 Pro Questions & Answers] codified_canon:
Light bleed from icons at top of camera app?

I didn't see this issue mentioned here and couldn't find it by search... But maybe I missed it.

Is anyone else getting light bleed in irregular patchy patterns that extends downward from the icons at the top of the camera app, appearing whenever switching/cycling between camera modes (photo, portrait, video, pro, etc)? For me it's excruciatingly reproducible.

I need to be in a somewhat dim (not necessarily super dark) room and have brightness turned up somewhat. Also, if not in a very dark room or in night, the camera sensor needs to be covered to darken the viewfinder (camera view window).

Then, when cycling between camera modes their is a somewhat bright flash of blotchiness that floods down into the viewfinder. It is brief, but happens evertime when switching between any two modes except "more" option.
[Huawei Mate 20 Pro Questions & Answers] sevanig:
I got a replacement model with a BOE screen, no green tint so far, however I think i liked the LG screen better (besides the green tint).

The LG appeared a little cleaner and clearer.

Mostly because this BOE screen has a blue colour shift when viewed from an angle, which may be more annoying than the green tint I had on the edge of the LG screen...

Any one else having a colour shift on their BOE screens??
[Huawei Mate 20 Pro Questions & Answers] Shadey1:
Thanks for this, I am watching with baited breath as I was about to pull the trigger on one and the thought of it hulking out on me is putting me off. My s8+ is creaking at the seams, and the Mate just seems too good!
[Huawei Mate 20 Pro Questions & Answers] djBarren:
Pure luck. As I lifted a replacement from Carphone Warehouse last night and its frigging green straight out of the box. Raging.
[Huawei Mate 20 Pro Questions & Answers] Orabas:
Ah sorry to hear that. At least we know they do have BOE if you went for another replacement
[Huawei Mate 20 Pro Questions & Answers] PakaDingDing:
Had mine since day 1, nothing so far but fully aware of the issue and will be keeping my fingers crossed I have a good LG panel.
[Huawei Mate 20 Pro Questions & Answers] Shakuri1987:
I have just got off the phone with Huawei customer services UK and they told me that they are aware of the issue with green screen and are contacting customers affected they are offering to replace phones. Albeit that means sending it to Huawei and waiting for replacement.

They also told me that they are working with retailers to make sure they have batches with working screens.

Personally I am going to speak to Vodafone to see if they have the new batch as I can get it replaced a lot quicker.
[Huawei Mate 20 Pro Questions & Answers] siaosi:
I was wondering what do they do with the returned phones. I hope they are not just re-selling them...
[Huawei Mate 20 Pro Questions & Answers] GrumGrum:
Got my replacement updated and restored through the cloud easy enough, obv not as easy as apple but hey ho, and gues what green screen lg panel right out of the box. Going to return and get something else its a shame as I really did like the cameras on it but that doesn't make a phone for me.

Dont hold your breath matey, my replacement was from Vodafone today and out of the box crap :(
[Huawei Mate 20 Pro Questions & Answers] stewartk:
Just got my 3rd phone from Vodafone its the same LG. Let's just wait for it to go green. Then I'll. Either contact Huawei and get them to swap it or get a different phone. Just not sure what to do for the best and nothing is better than this phone
[Huawei Mate 20 Pro Questions & Answers] Shakuri1987:
They're out of stock and think it's due to then being told to stop selling and wait for a new batch, that's my guess anyway. Either way it's on back order.
[Huawei Mate 20 Pro Questions & Answers] markybhoy75:
Noticed this issuse on my phone today. Also flashes bright green on the lower half every now and again.

EE uk says ive to contact huawei for a replacement . Is this right ? My contract is with EE surely they should replace it?

Marky
[Huawei Mate 20 Pro Questions & Answers] jadaress1:
That doesn't sound right, I'm sure at least the first year the retailer who sold you it has to deal with it.
[Huawei Mate 20 Pro Questions & Answers] wtabram:
Spoke with mobiles.co.uk today as I'm waiting for my replacement. The guy said they are out of stock and were returning all of the 1st batch to Huawei. Also that they are waiting for a new batch you arrive Hopefully he was telling the truth and not spinning me a line and I get a perfect replacement.

Here is mine ,just after 4 days with it, that wallpaper is suppose to be black
[Huawei Mate 20 Pro Questions & Answers] Merlinux:
Hmm I noticed you had to tilt your phone on its side in the 2nd picture to see a bit of green hue along the edge. When I look at mine straight on (had mine for a day only) there is no green, but when I tilt it about 30-45 degrees, I can get it to show a slight green like you have, but I believe this is normal... What's abnormal is if you are looking at it dead on and it's glowing green somewhere along the side. I think so anyway...

But like I say, have only had mine for a day, will continue to monitor it.
[Huawei Mate 20 Pro Questions & Answers] Mumb1ing:
I had the LG 51 screen on my JB HIFI phone. Currently getting assessed...
[Huawei Mate 20 Pro Questions & Answers] jonascos:
The store should replace it. I had the same problem and they replaced it for me and they told to come when it starts showing up
[Huawei Mate 20 Pro Questions & Answers] 1979Damian:
If EE supplied the handset then they are 100% legally on the hook for the warranty, your legal "agreement" is with them as the seller, not Huawei. You'll still have a warranty with Huawei but in this instance the retailer should be sorting it and sharpish (once they have appropriate stocks available).
[Huawei Mate 20 Pro Questions & Answers] jonascos:
Huawei should have done better duren the test be before selling but think it's has something to do with the environment there did not see any issue
[Huawei Mate 20 Pro Questions & Answers] denzel09:
still no communique from huawei, ridiculous
[Huawei Mate 20 Pro Questions & Answers] Zilongofchangshan:
I wanted so much to believe that Huawei would do the right thing

It's been 10 days for me since I reported my screen issue with Huawei at their Service Center. No official statement except that they will replace the unit. The order was placed on Nov 4 and I have since posted a video on this at:

youtu.be/HhVPv2Xng9c

youtu.be/DIKx7yc7APM

It's now more than just the green tint on the top and sides. It flashes in the morning especially on the lock screen and sometimes can be quite sustained and intense.

Huawei says will take 2 weeks for the replacement units to arrive from China. I hope they didn't just replace the screens and shipped it over to us. I would be very pissed since the phone is less than 3 weeks old in total. For the $1,300 that I paid for this which is on par with Note 9, the users ought to get a brand new unit. One with BOE screens and not LG again. That would be nightmare all over again.
