Obviously yes, going before 30 days timescale is advisable but when you're on your 4th replacement and you are beyond that time does that mean that they would only be entitled to repair? I would think that every replacement resets 30 day hassle free exchange?

Why not return it for full payment? I think it's hard to sell a defected device.
[Huawei Mate 20 Pro Questions & Answers] stef816:
Very little but I have the impression that it began to do it
[Huawei Mate 20 Pro Questions & Answers] cvenk:
Do not know.

I did UV light before my 1st boot. Just to be safe did not want any heat or bends .
[Huawei Mate 20 Pro Questions & Answers] darkoroje:
Why would UV light help?
[Huawei Mate 20 Pro Questions & Answers] lynxblaine:
UV light is used to cure the glue when applying the glass to the screen. The theory is that the glue isn't cured fully so that's why it's green. I'm not 100% sure myself it's the glue, but I don't have any better suggestions to offer.
[Huawei Mate 20 Pro Questions & Answers] stuclark:
That's not the same; that is merely an optical illusion caused by the curve in the screen at the edges. All OLED screens have a hue shift when viewed from different angles

(it's what Huawei initially tried blaming the Mate 20 Pro issue on)

---------- Post added at 09:18 AM ---------- Previous post was at 09:08 AM ----------

That's good news; I've got my replacement being delivered to the local CPW store in London today. Was yours a twilight model?

I don't think that's got anything significant to do with it tbh. *IF* it is a glue not being cured problem then sure, getting the phone hot may exagerate the issue, but it won't cause it in itself. My LG screened original started developing the green glow after 4 days use, and I never even unboxed the charger!
[Huawei Mate 20 Pro Questions & Answers] skoobee:
i have been using the 40w charger since day one and my mate has no green tint (LG)
[Huawei Mate 20 Pro Questions & Answers] urbaniz9r:
Having the screen issues now aswell since yesterday evening...

Getting a replacement tomorrow directly in the shop
[Huawei Mate 20 Pro Questions & Answers] BillPil:
Please state the manufacture date and where you are located.
[Huawei Mate 20 Pro Questions & Answers] skoobee:
18A16, Uk
[Huawei Mate 20 Pro Questions & Answers] BillPil:
Both you and urbaniz9r have similar manufacturing dates. It seems that former batches don't have this issue. I've got 3 devices with 18A25 and all three have this issue. I am also UK based.

It would be useful if anyone with similar batch numbers can confirm my thinking...
[Huawei Mate 20 Pro Questions & Answers] w2cfx:
My original one which I returned was 18A19. My new one is 18A11, which is now almost bad enough to be visible under shop lighting. Does anyone have a source on the 18B dating thing? I'd love to not be gambling on another replacement.
[Huawei Mate 20 Pro Questions & Answers] ero69:
That's probably why next batch are working.... more time for glue to cure.

:D

What's your number written behind the LG entry? Maybe it's just one faulty batch.

My display is an LG-01-18-10-43 and for now, it's just slightly brighter at the edges at min. screen brightness.
[Huawei Mate 20 Pro Questions & Answers] bazda:
Mine is also LG. Seriously, they ****ed up iPhone XS Max also. Probably they won't let me replace next time so i need to get refund... What ever now...

For me its LG-01-18-10-51
[Huawei Mate 20 Pro Questions & Answers] Shakuri1987:
Mine is also LG-01-18-10-51. Awaiting stock from Vodafone before I can get a replacement. Hopefully that means it'll be a different batch and hopefully different screens. Amazes me that this hasn't been tested.
[Huawei Mate 20 Pro Questions & Answers] sirpaul82:
Mine is LG as well, bummer, went to O2 shop ask for replacement, Twilight is out of stock for at least 2 weeks, thankfully I have 30 days to replace faulty device

Mine also has this number. Is there any way to know from the outside of the box what screen it would have?
[Huawei Mate 20 Pro Questions & Answers] stewartk:
I've got the LG. This is my. Second. Still OK after 6hrs use
[Huawei Mate 20 Pro Questions & Answers] stewartk:
I got my replacement today.
[Huawei Mate 20 Pro Questions & Answers] Shakuri1987:
Interesting I requested it yesterday but they said both colours were out of stock. Keep us updated on how the replacement is.
[Huawei Mate 20 Pro Questions & Answers] stewartk:
I called yesterday morning and it arrived today. Maybe its good they have none left. You might get a newer batch
[Huawei Mate 20 Pro Questions & Answers] Shakuri1987:
Yes, true. They told me 3 days but not holding out for that. Hope a new batch does fix it or I might have to consider the 6t.
[Huawei Mate 20 Pro Questions & Answers] stewartk:
I've looked at the 6t. I don't think it's as good as mate 20
[Huawei Mate 20 Pro Questions & Answers] leo72793:
Agreed. It's not bad but the face unlock is just a picture. Not 3d. Probably easy to fool. My m20p comes tomorrow. Hope cloves last shipment mine came from has no issues. Cause they'll be sending me another then I'll send mine back. In the USA, and my m10p is being given away immediately as my buds m9 that he got from me is broken and slowly falling apart. (he's rough af so he never buys new. )
[Huawei Mate 20 Pro Questions & Answers] McMiller:
Got an LG Display in my Mate 20. Here also not as bad as some other here, but also still noticeable green on the left site.

HW-Info: LG-01-18-10-51
[Huawei Mate 20 Pro Questions & Answers] djBarren:
So LG-01-18-10-43. Getting worse as time goes by. My phone will be a week in use on Saturday.
[Huawei Mate 20 Pro Questions & Answers] Nicelysedated:
Is there anyone with an LG display that doesn't have this problem to some extent?
[Huawei Mate 20 Pro Questions & Answers] wqwave:
My m20 pro is LG display. No screen issue out of box. I am monitoring this issue and had been running youtube burn-in fix video for about 8-10 hours already. No issue yet. Trying to run for more hours to see if it happens. If after 3 days still don't happen, *fingers crossed* it won't happen afterwards. Else will ask for replacement. Problem is... The replacement better not be an LG display again :rolleyes::rolleyes:

By the way, China's having issue with LG screens as well. From what I see, none of BOE screen had such issue... Yet.

[Huawei Mate 20 Pro Questions & Answers] shineyads:
Have you noticed if your colours aren't quite as vibrant as the LG screens?
[Huawei Mate 20 Pro Questions & Answers] pincho21:
Yes it's totally different also in some angle I can see different color on white wallpapers but for now everything is OK without any issues.
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
Right, got my third replacement:

Some things to note:

Again LG screen, phone was manufactured 23rd October same as my second replacement.

Screen does have the green screen problem, but as always it's not too bad to start off with.

HOWEVER, an interesting point for me, the fingerprint scanner and face unlock are working VERY Well, compared to my previous 2 phones were they were very intermittent.

So, clearly there are quality issues on multiple fronts here.

I will think for 2 more days on what to do, as it looks like getting a BOE screen is not so easy.
[Huawei Mate 20 Pro Questions & Answers] pincho21:
It's very easy I just call on my letailer Vodafone and tell I want phone with BOE screen from new batch and after 3 days I received my twilight with BOE screen.
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
Which number did you use, and what did you say? I'm also with Vodafone
[Huawei Mate 20 Pro Questions & Answers] enrique71:
I would like to know if this issue is widespread, or are only a few select models bad? I can't imagine the entire batch of hundreds of thousands M20Ps are ALL bad, this would be a disaster for Huawei PR. I ordered my M20P, and of course I'm nervous about what I'll receive. Any input from those who may have bought a M20P and no issues to report?
[Huawei Mate 20 Pro Questions & Answers] pincho21:
I call on 191 and telling I'm loyalty customer in Vodafone already I have again problem with me second device and also is LG screen.

I would like replacement again but for 100%working phone.

Also I telling I don't blamed Vodafone because I know its not his fault after couple hrs call me some guy from high department and tell me my phone will be dispatched soon and will be without any issues at all.

Also from Monday I have again 30days from change my mind.
[Huawei Mate 20 Pro Questions & Answers] Phil750123:
Been waiting over 3 weeks for a replacement, got one and bloody LG Screen with the issue out of the box! Three UK

Not sure if I can be bothered to change it for another one to just get the same issue or just swop to another phone
[Huawei Mate 20 Pro Questions & Answers] maverick1103:

So on a side note, I did a warranty query here: https://consumer.huawei.com/my/support/warranty-query/

This is on huawei site and it shows that I have a two year warranty? Is that right? I haven't heard anything about an extended year of warranty but that is cool if it is the case/
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
Yes, and if you register for HiCare on your device, it's upgraded to 3 years, with a free screen replacement in the first 3 months if you damage it by accident

Finally had time to go back to Carphone Warehouse and ask for a replacement for my first device I got from pre order.

Got a replacement straight away and it's a BOE!

Guy in the store wasn't aware of the issues but had no problems exchanging it.
[Huawei Mate 20 Pro Questions & Answers] lynxblaine:
Went into vodafone, they had an 'old' Huawei Mate 20 pro from 26th Oct 2018 (from SN), mines is 16th Oct 2018. I rejected it and will be getting them to send me a newer one in the post for an exchange.

I've just picked up my replacement twilight from Carphone Warehouse and it's a BOE screen :)

So far I can't say I've noticed it being any less vibrant than my old LG screen'd device was.

For those who have bought from CPW in the UK - most stores don't have any stock, but there's a few hundred in the warehouse for next day delivery to the stores - that's where mine came from :)

---------- Post added at 02:55 PM ---------- Previous post was at 02:53 PM ----------

As a side note, I've noticed that every retailer (certainly that I've been in) have a dual-sim varient as their display model; and having done a quick and imprecise screen test on them (turn brightness down, cover phone in jumper etc.) none of them seem to have display issues; so I wonder if all those phones went out with BOE screens?

... if so, do we think maybe Huawei knew about the issue before they admitted it?
[Huawei Mate 20 Pro Questions & Answers] gmangt4:
I have the dual sim from 3 UK and its an LG screen
[Huawei Mate 20 Pro Questions & Answers] whoops1234:
I dont know if you saw my pics from earlier in this thread but I did a side by side comparison and the BOE was noticeably greyer and less vivid so much so I had trouble reading it in the dark. I am now on another LG that seems to be holding up ok
[Huawei Mate 20 Pro Questions & Answers] BillPil:
Are you referring to twilight variants only?

I am interested in the black one...
[Huawei Mate 20 Pro Questions & Answers] iberr:
Yes i saw it and responded it just below. Thanks. I just asked for several reviews to know if I can refuse a BOE in return.
[Huawei Mate 20 Pro Questions & Answers] stuclark:
I'm specifically mentioning Twilight only; but I suspect the same situation will exist for black ones. (whether they're from the "same" or "earlier" batch I don't know though, as the black ones shipped before the twilight ones initially)
[Huawei Mate 20 Pro Questions & Answers] keyz86:
Can't say I've noticed a difference, if anything I think the BOE is better all round. Seems more accurate.
[Huawei Mate 20 Pro Questions & Answers] crazdgrunt99:
Just a quick question regarding the S/N is it possible to work out the batch date by looking at the S/N on the bottom of the box? If so guessing I want a B in the S/N?
[Huawei Mate 20 Pro Questions & Answers] Spood:
There are 5 characters to look for.

XXYZZ

XX = year, so 18, should be easy to spot in the S/N

Y = month in hexadecimal, so 9/A/B so far (B is newer)

ZZ = day

Newest batch so far was 18B14 or something like this iirc, I think I saw one person here commenting that.

September/October batches are more likely to have the issue because there is no way they could have fixed production by then. So those batches are a lottery.

Early november (18B05 I think) is probably also random since I doubt they'd have fixed it yet too since the issue got showcased a lot towards the mid/end of october.

The bewer the better. Idealy a brand new batch with an LG display seems to be the best thing to wish for : less chance of an issue and better display overall it seems.
[Huawei Mate 20 Pro Questions & Answers] Ksmy89:
Has anyone managed to return a handset with an affected LG screen to Very? I have just phoned their customer services to be put through to Huawei service repair line, they have made me check for a software update and do a factory reset to see if the issue is still there...feel like they are trying to fob me off!
[Huawei Mate 20 Pro Questions & Answers] Spood:
(Double post sorry)

After seeing it in a shop I am really tempted to just get the regular Mate 20 instead. However the LCD instead of OLED at that price just feels wrong. And the screen is not nearly as bright as the Pro version, but I like the size and notch a lot more. And I'm not quite sure I'll like the curved display of the M20 Pro.

Sadly there are little to no review out there. The closest to the Late20 seems to be the OP6T. Not sure which would be better, since OP has an OLED display, but the Mate feels better in hand and has better battery + a future proof SoC (but less RAM)... I havent been able to test video playback on the 6T at the store, it didnt have any sample photo/video. Has anyone tried both ? What would they advise ?

I think I'll try the 20Pro and change for either the regular 20 or a 6T if I cant stand the curved edges...
[Huawei Mate 20 Pro Questions & Answers] crazdgrunt99:
Cheers for the reply that's very helpful :) I shall be asking my local three store to see if they have any in stock.

Day 3 with my BOE screen replacement and I'm pleased to say I've had no issues with green screen! I don't have any issues with the screen's vibrancy compared to the LG model I had either.
[Huawei Mate 20 Pro Questions & Answers] jhs39:
I have gone through every post in this thread. It seems like there are way more reports of display problems on XDA than anyplace else and that easily over 80% of those reports are from junior members with new accounts.

Conversely, there have been thousands of reports of battery drain and overheating for the OP5, 5T & OP6 on the official One Plus community site but owners on XDA strangely seem to be immune to those issues.

There were also new reports every day of Pixel XL phones dying (black screen of death) on the official Google Pixel site starting immediately after launch with numbers growing exponentially larger every month but Pixel XL owners on XDA never encountered that issue either.

I think people should be skeptical of at least some of the posts in this thread. I have no problems with my Mate 20 Pro display (which is an LG). I know another half dozen people who purchased this phone and not a single one of them has a problem with their displays. Anyone can make their display appear to have gone hulk in a photograph by adjusting the color in settings and then taking a picture in a dark room with no flash.

There are people in this thread claiming that every LG display is defective. If that were the case don't you think you would be reading about it on other Android news sites? Even the XDA News Feed has posted no story suggesting anything widespread as that.

[Huawei Mate 20 Pro Questions & Answers] helder_gz:
Well, I can't speak for others. All I know is that my device (HM20P - LG screen) has the green glow. It's not very visible during the day, but whenever I am in a dark room it's very noticeable (using apps with a dark interface, like Netflix, Spotify and the camera).

[Huawei Mate 20 Pro Questions & Answers] iberr:
I'm junior indeed. Maybe is it because I've never had any trouble with my last devices. You certainly know that if we write something about a phone in this kind of forums it's certainly about the cons not about the "normal use" of the phone.

You'll never get the idea to write on a forum just to say that your phone is normal and have no problems. Otherwise you do.

For that price, the phone AND the service need to be irreproachable. I have had the problem of the pink line on the Galaxy S7 Edge. Samsung fixed it at least one hour. New battery and new screen after one year and half of use.

We are not here to waste our time for something marginal. It's a huge issue and Huawei has to deal with it.

Sorry btw for my english, I also waste more minutes by trying to write something easily comprehensive.

The complaints are only on XDA? Here is a thread on Huawei UK community about this very same issue: https://uk.community.huawei.com/mate-20-series-20/mate-20-pro-green-edges-on-screen-679/index31.html. It has 777 posts, by far the largest thread. You think they are all inventing this issue? They are numerous other posts on the Internet.

It is obvious that Huawei's quality control has failed, and that a significant portion of first batch of the phones has display problems. Just because you have no problems with your phone doesn't mean that other people don't.

[Huawei Mate 20 Pro Questions & Answers] Spood:
I don't really believe any flagship camera can be "bad" in the current year. Especialy on a 800€ phone. Not as good as the Pro, sure, but definitely up there.

Also I only have an LG V10 right now so really anything is ak improvement, and I'm not too big of a camera user.

I mostly use my phone for entertainment (web browsing, messaging, youtube, movies, music, some games but not even that many), the camera is a bonus. I like big beautiful screens, good audio with headphones, and most importantly a good battery life.

:cool:I think this is a software problem... Te galaxy S9 plus have same problem on the edges on the screen lstter Samsung update the firmware and add an options to calibrate the edges of the screen like color temperatura and gama red, green, and blue...

Our mates 20 pro dont have this option... I found the only way is on the screen option disable the natural color and the green faded color notably down on the edge principal on the notch area... May be this tip is useful for you dudes...
