[Huawei Mate 20 Pro Questions & Answers] Crucio_:
Just for comparison, does anyone have a picture of the OLED Tools test on a device that is not affected by the green edge issue. I'd like to see how different it looks?

About to go see about swapping my device, i have the emerald green version from CPW in the UK. Has an LG panel with the number LG-01-18-10-51, the green bleed is there but not as bad as it is in some of the pictures in this thread. It is still distracting when i'm watching shows in low light.
[Huawei Mate 20 Pro Questions & Answers] Trident10:
I really think ALL the LG panels have the issue. I think that are some people who are not testing in the right conditions, but I belive all have the same problem..
[Huawei Mate 20 Pro Questions & Answers] siaosi:
Damn, mine started getting the green edges now. LG screen, but I thought I was in the clear. Unfortunately not...

I got it through Carphone Warehouse, O2 contract. Does anyone know who would be the best one to contact? CW, O2 or Huawei for this?

I'm going with huawei now. I've had three phone from Voda all with same fault. If there was another phone the same or similar then I'd get that but nothing is out yet

Ok, thank you for the answers
[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
Replacement seems 'ok' so far, can't say the slight green tinge at the bottom has got worse over first couple of days

BUT...

I have noticed the 'minimum' brightness seems brighter than before, it's now uncomfortable when using it in bed etc...

Have Huawei done this to try and cover it up?
[Huawei Mate 20 Pro Questions & Answers] MartPwnS:
My replacement device had pixel errors 4 black spots...

Going back to Deutsche Telekom.

I hope the 3rd one is issue free.
[Huawei Mate 20 Pro Questions & Answers] magnatom:
I'm just off the phone to Huawei UK and....well, not much really. They said I need to speak to my provider, and whilst they admit there is an issue, there is still no official announcement from Huawei. So, I've decided to try another replacement via Vodafone. As ever, that was very easy, and interestingly, they have said I should get notification of shipment of my new phone within 24 hours. That suggests that they aren't waiting for stock. Not sure if that's a good thing!

Oh well, lets see where this leads.... This will be my 3rd...
[Huawei Mate 20 Pro Questions & Answers] denzel09:
From another forum:

Errors can be 2:

- design error (lack of black background in the panel or components pressing against the panel)

- design error (lack of magnetic isolation that generates aberration)

The second error is due to an early deterioration of the panel and PROBABLY the hulk effect due to the stimulation of the pixels moving away from the center.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
I'd push Huawei, the person I spoke to yesterday admitted that they recognise it as a fault and are sending me a jiffy bag to send my phone to them for a full replacement (the email I had said repair which was worrying though so waiting on clarification).
[Huawei Mate 20 Pro Questions & Answers] GiancarloMorr24:
Did you end up returning your device to Clove? If yes, did they pay for shipping back to them?
[Huawei Mate 20 Pro Questions & Answers] BillPil:
Someone in the official Huawei UK forum for Mate 20 Pro mentioned that their provider told them not to pursue another product exchange and wait for the official response of Huawei due next week.

Does anyone here have any info on this?
[Huawei Mate 20 Pro Questions & Answers] charming.arpit:
I noticed this problem of green edges in my phone yesterday. My phone also had LG display. Reported today to Huawei service center this morning. Huawei was very proactive and they replaced my phone within 10 minutes. I live in Dubai.

They replaced my phone with BOE display.

I personally think this display quality and even touch screen responsiveness is far better than LG display.
[Huawei Mate 20 Pro Questions & Answers] mwillo:
Hi can i ask what colour device you have asked for, as I raised a swap on monday with vodafone for a twilight and was told there was no stock avaialble and they have placed a handset on back order.

I still havnt heard anything.
[Huawei Mate 20 Pro Questions & Answers] thetroublewith:
I just called and had much the same experience! Even though the person on the phone acknowledged the fault and was taking down details like my phone's IMEI number, etc I was just told I'd be best taking it back to Carphone Warehouse for a replacement. I explained I had read updates from many people who are now on their second and third replacement devices but I was just advised to call back if there was any issue with the replacement device. I'm half tempted just to take it back to CPW, get a refund and wait it out until early next year to see if they fix the problems.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
i did, i had them pay for it. Told them i wasnt paying $100 to return it, and id file a paypal claim theyd be reimbursing me if they made me. I had a label next morning
[Huawei Mate 20 Pro Questions & Answers] GiancarloMorr24:
They’re giving me the runaround saying they won’t pay for my return shipping. It’s pissing me off.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
I sent them this... If i do not receive a paid label for return shipping, to completely RETURN this device for a full refund including original shipping price BY ******* COB your time ( 5pm UK time, 12 noon USA time ), i will file a claim. I have contacted paypal directly before filing a claim against your company. I am doing this as a final act of good faith to resolve this issue.

Make sure you have the time frames for YOUR time zone, and the ***** is the day you have coming up. Mine was sent friday, COB was monday.... So i got a DHL label almost instantly. I got sick n tired of their bullsh*t
[Huawei Mate 20 Pro Questions & Answers] GiancarloMorr24:
Fantastic! Thank you.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
Hope it works for you. Insane that adefective device means i have to pay...
[Huawei Mate 20 Pro Questions & Answers] GiancarloMorr24:
That’s exactly what I was thinking when I first contacted them about the issue. Appreciate your help with this.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
Good luck! If it works great! This is why i use paypal. They help the buyer, as per the reasoning makes full sense. I explained that had it been i didnt like it or want it anymore, then it should make me but NOT for defect
[Huawei Mate 20 Pro Questions & Answers] @home:
I just spoke to CPW & they told me contact Huawei. They are not interested, this is my second device.
[Huawei Mate 20 Pro Questions & Answers] marcadam:
Have you told them they are responsible under the Consumer Rights Act 2015? Your contract is with CPW not Huawei, you also have the right to a full refund if the goods are faulty/not fit for purpose within 30 days.
[Huawei Mate 20 Pro Questions & Answers] @home:
They told me to either ring Huawei or take it to CPW store & they will send it to Huawei who will then deiced if I can have a refund. All very odd
[Huawei Mate 20 Pro Questions & Answers] magnatom:
It's twighlight, but I have a sneaky suspicion that I won't hear anything in 24 hours. I'm not sure the operators are always fully informed.....

I've had 2 in twilight one for my dad and another for myself. Dad got his 5 days after ordering and mine 3 days. Both LG screens and dads went after 4 days use. Vodafone are exchanging once stock is back in. I've just received mine today so we'll see how it goes

My phone company just got a new shipment in i think, since theyve been outta stock for almost 2 weeks, so im really considering buying one, i would really love to have this phone, but those screen issues are playing with my brain.
[Huawei Mate 20 Pro Questions & Answers] mscion:
Is gluegate a problem primarily for phones bought for use in UK? Or is this a global problem. For what its worth, the sales representative from Wonda Mobile (Hong Kong) told me that they have had no reported problems with the green appearing on edges. Is this believable?
[Huawei Mate 20 Pro Questions & Answers] shanume:
I got my mate 20 pro replacement today and I got the BOE-02 panel, can't be more happier, and I can see the difference of the quality from BoE and LG, I love the BoE more.

By the way, i am from Denmark :)
[Huawei Mate 20 Pro Questions & Answers] niclas90:
From where? I'm on my second Mate 20 Pro in Denmark now, and both have been green LG's.
[Huawei Mate 20 Pro Questions & Answers] shanume:
I got mine from Telenor, but my first mate 20 pro was sent to Care1 and I telling them that I want a replacement, and I don't want a LG panel again.

Care1 contact Huawei and get a new one to me, i am sure Huawei know what batch model from Imei has what panel. Just don't get a replacement from the store.
[Huawei Mate 20 Pro Questions & Answers] TimTaylorX:
So how do you Check which screen is there ...
[Huawei Mate 20 Pro Questions & Answers] mscion:
Ok. I see folks from Denmark chiming in.

So is this primarily a problem in EU?
[Huawei Mate 20 Pro Questions & Answers] UM Marneus:
Download the "Device Info HW" application on the Play Store and look in the "General" tab the value for "Touchscreen" .

As you can see in my example, I've a LG display...
[Huawei Mate 20 Pro Questions & Answers] shanume:
No I have a lots of friends from Hong kong, China has this LG panel issue as well. some people are just lucky from the beginning, I think all first batch model are with LG panel :(

Got my replacement phone from mobiles.co.uk today.

Has an LG screen that looks perfect at the moment. This is supposedly from a new batch so time will tell if it's a any different.

I've taken 'before' photos on day 1 and will take photos as soon as I notice any change.

I couldn't see anywhere that stated a production date? Is there such a thing on these? Would be interesting to see if we are actually getting new batches or not.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
only one that comes native Googleplay is the twilight sadly. i dont want the hassle of chinese vpn to get stuff to work. Waiting til they give all colors international 256/8gb

Wait so the rest of the colors don't come with the play store?

How is yours? Is it LG?
[Huawei Mate 20 Pro Questions & Answers] jordand77:
Update, got another phone today it has BOE screen, the screen is perfect.

1st device - green corners after 12 days of usage.

2nd device - partial green screen out of the box.

If you have Huawei Service Center in your city go straight to them, they will replace the phone as many times needed ( from what I know they don't know if a phone has LG or BOE screen, unless they open the box and check the phone manually. )

Some guy I met at the service center said he had 6 phones all with LG screen, and 7th was the lucky to be BOE.
[Huawei Mate 20 Pro Questions & Answers] leo72793:
Nope only the Twilight. Hivision n stuff will all be in chinese also.
[Huawei Mate 20 Pro Questions & Answers] Green Hulk99:
DOnt LOOSE HOPE GUYS!!!! Huawei Philippines started giving M20 Pro with BOE Screen as replacements...as of yesterday... :)

Same here in Singapore service center. I had requested non LG screen for my replacement but they can't make that call.
[Huawei Mate 20 Pro Questions & Answers] stuclark:
I'm starting to get a green tinge at the top of my screen, kinda like a gradient going to black lower down the screen.

So far it is not too annoying, but definitely there...

This is at 7 days of use on UK stock Twighlight with LG screen
[Huawei Mate 20 Pro Questions & Answers] defendergr:
finally and my panel is infected from this green thing :( I have send it to huawei for review and replacement I hope to get soon a good replacement.

the device is perfect, everything is perfect in this device except that glue...
[Huawei Mate 20 Pro Questions & Answers] BillPil:
That is exactly what I am experiencing on the 3rd day of my 2nd replacement. Green tint to top edge and around the notch. Not so annoying though as in the previous 2 handsets. UK sim free, black device with LG screen...
[Huawei Mate 20 Pro Questions & Answers] Indy121:
So it almost made it a week, but the green is back. No where near as bad as the first phone, but it's still there. That and the fingerprint scanner does not work.

I will probably hold off a month or so before I request another, just so hopefully all the first load of phones are gone.

One thing I am hoping someone could help with - is there a way to back up my saved passwords / front screen / apps / themes / settings etc, so I don't have to set the phone up from scratch? The only thing that restored when I changed the phone was the apps downloaded.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
If you have any sort of green tint don't settle. You're paying close to £1000 for this phone and any small issue that from evidence only gets worse over time is going to drastically reduce the value compared to others without the issue.
[Huawei Mate 20 Pro Questions & Answers] sheikgr:
Use Huawei's Phone Backup app on your phone, it does a really great job, it backs up everything even application data
[Huawei Mate 20 Pro Questions & Answers] Indy121:
Is this only to back up to external storage / PC?

Don't want the hassle of having to connect the phone and would rather as cloud based solution?
[Huawei Mate 20 Pro Questions & Answers] Biggenz:
Is there anyone with an LG panel that hasn't had any problems? I've just received my first phone and it's got the LG panel.
[Huawei Mate 20 Pro Questions & Answers] Trident10:
I really think ALL the LG panels are infected with the problem. Some people aren't testing in the right conditions, though. Some people are testing with black screens (and it doesn't happen in black screens, only in dark grey ones) or not with the brightness in the minimum and in a dark room.

I think it's a problem of all the LG panels.

Truly dissapointed for Huawei didn't said anything about this yet.

I got a Twilight model from Vodafone, received it on the 6th, I'm now on day 8 and have no signs of green the screen everyone's been reporting and I have a LG screen.

The only thing I've noticed is on a grey/black screen I see some light leaking on the edges but it's white and not green.

Maybe I've been lucky or this is the start of it I'm not sure.
[Huawei Mate 20 Pro Questions & Answers] Diazz72:
That's the first sign...wait a little bit longer and it will pop up green :/
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Ah balls!! :crying:
[Huawei Mate 20 Pro Questions & Answers] Duncan1982:
So glad I got the BOE display from Vodafone UK, Twilight, looks like I got lucky, however there is a very slight colour shift off axis but most amoleds have this to some degree.

All I can say is whew, but Huawei would be best in formally Acknowledging this issue and making a public statement, and correct it but stopping production with LG. As as far as I can see it's just that display that is effected?
[Huawei Mate 20 Pro Questions & Answers] Phil750123:
still awaiting my first replacement from three, I am guessing they have delayed an order to make sure they get a good 2nd batch.

Got my device on launch day 26th ,first noticed about 5 days in, got worse and worse but seems to have settled for the past week or 2. Noticeable anything below 50% brightness.
[Huawei Mate 20 Pro Questions & Answers] colts187:
Are you going to try to exchange it? I'm not really sure how to handle it since its an import. I know Huawei won't support it here in the US. :(

---------- Post added at 07:25 AM ---------- Previous post was at 07:22 AM ----------

I can't believe they haven't released a statement yet. I bet most people won't notice the defect for some time and will be way past return window. I have to say I'm losing some respect for them.
[Huawei Mate 20 Pro Questions & Answers] magnatom:
An update from me.

I called Vodafone yesterday to try and get a third handset. The operator told me I'd hear within 24 hours about a delivery, but as suspected I haven't. So I called again. First chap was pretty clueless and couldn't understand most of what I was saying ( I've a Scottish accent, but not that strong!). Fortunately he passed me on to someone else. They confirmed that Vodafone are awaiting a new batch, which is a good thing! She also managed to order one of those for me as the operator I called yesterday hadn't actually done what she said she'd do...sigh.... Anyway I have one of the new batch ordered. She couldn't confirm when they would arrive, but did say I should have an update in 3 to 5 days.

Fingers crossed this new batch solves the issue. My phone is now at the stage where you can start to see the green glow in normal light.
[Huawei Mate 20 Pro Questions & Answers] Jonathan-H:
I am on my third one. EE called Huawei last night, and confirmed to me that they had admitted it was a hardware fault and were happy to exchange it again.

I received a new one this morning, and it is LG, and out of the box exhibits some green tint around the edges.

I am now unsure what to do as I imagine over a 6 month period it will become unusable?

Argh I love this phone but the screen issue is annoying.
[Huawei Mate 20 Pro Questions & Answers] BlockXVI:
2nd phone in emerald green. LG-panel again, out of the box worse than my initial one. Ordered from 1&1 in Germany who prove themselves very cooperative. Wanted to swap for another handset. No chance since I came from a Pixel 3 XL which has been swapped out for the Mate (Speaker-Problem). Let's see how that develops.
[Huawei Mate 20 Pro Questions & Answers] kirkdis:
I picked up today my exchange device. Huawei philippines did a great job. They constantly hold the communication and send an exchange device to a shop near my location. Thanks for that. They checked the device afront and even it was LG screen it looks great for now. I will see how it stays in the next few days. What I realized is that my exchange device is one of the really first batches and it seems like much better than my faulty one.

Maybe we should start a list with serial numbers where the issue appears...

I will start herewith:

LHS7N18A10019134 - LG Green Glow

LHS7N18A10000334 - LG still good after 1 day of usage

Maybe there is a chance to find out which devices are affected...
[Huawei Mate 20 Pro Questions & Answers] Troutguy:
The problem is also very big in Sweden. I'm currently on my third device, the best so far but far from perfect. Talked to Huawei Sweden just now and their solution is to keep trying until you get a device that's problem free…. What a circus
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Question for you, I'm with Vodafone and called them yesterday to ask them about the 30-day replacement process, I was told that if my phone's screen does go all Hulk on me then I need to go to a Vodafone store for it to be assessed, then they'll order a replacement handset which will be delivered to me; so I'll be without a handset during this time.

Is that what happened with each of your replacements?
[Huawei Mate 20 Pro Questions & Answers] magnatom:
No. I've just phoned up, told them about the issue and they have arranged a replacement. They haven't even asked for pictures, although I could provide them.

They send the phone and I give the courier the old phone when he arrives to take away. A bit of a hassle as I need to be there at a specified time, but much better than sending a phone away.
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Oh, that's interesting because that's what I thought the process was, however when I called up last night to ask they told me different... I'm happy about doing a swap over there and then because I can get it delivered to my works address, I just can't be without a phone really.

I was also told that the 30 day swap over resets every time I get a replacement, have you been told the same?
[Huawei Mate 20 Pro Questions & Answers] magnatom:
I didn't really discuss the 30 day swap, but I assume it does. I find big variability in the operators. Probably worth phoning again and saying that others are getting replacements at the door.
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Yes I think I will, I'm not one to just accepts the first response anyway, especially like you have stated others are getting replacements to the door. Thanks :good:

I bought my a week ago still no problem and I knew I had a LG 41 en after the update yesterday It showing 51 strange
[Huawei Mate 20 Pro Questions & Answers] xnpu:
This is normal. It's a screen firmware version. That's why mentioning it - which seems to be the trend here - is useless.

If we want to compare something useful we should be looking at the production date of the phone, which you can extract from the serial number. Mine is xxxxx18A27xxxxxx, which translates to October 27th, 2018.

It would be great if we can find some kind of cut-off date after which screens are fixed. (Also because you don't need to open the box to see the serial number.)

To test properly: install the OLED Tools app. This app was mentioned in an earlier post. Perform the uniformity test in a dark room, choose green or grey as color, and swipe to the left to set brightness to level 6. You will see the green glow at the sides. Or no glow if you have a perfect screen.
