[Huawei Mate 20 Pro Questions & Answers] mate20pro_London:
I'm having the issue, I've taken pictures over the last few days which are below.

To be honest, there are some other issues with this phone:

some applications have glitchy sounds

it's easy to press on the sides by mistake when holding the phone

EMUI 9 is ok but not as 'slick' as some other skins

pinch and zoom is not as easy as iphone

fingerprint sensor is temperamental (works 7/10 times), and face ID sometimes works flawlessly, and sometimes just doesn't work.

But... most of this is made up for by the great camera (and night mode), battery, and what I thought was a great screen, although from the first day a friend of mine pointed out the slight odd shadows on the screen, but I put this down to the curved edges. I guess it has got worse over time, as now it seems to be irritating me during the day.

I'm with Vodafone UK, and in theory have 30 days to return / change my mind.

Not sure what to do, as fixing an issue like this is a 4-6 week turnaround from first awareness to changes to consumer units.

Maybe I should cancel around the 28 day mark, and wait for Huawei to fix the issue.

It's strange there is no official statement, i chose this over the XS and Note 9, and if it wasn't for the wide angle lense, I would have already traded this in. Plus, there is a lot of heavy marketing for this phone in London at the moment...

Anyway, here are the pictures in various light conditions:

Regarding the slickness of EMUI, have you made your self a developer and decreased the animation speeds to x0.5? Makes a difference to the perceived quickness of things

How can l verify what kind of display l have?
[Huawei Mate 20 Pro Questions & Answers] galaxyYtester:
Download this app from Google Play, "Device Info HW":

https://play.google.com/store/apps/details?id=ru.andr7e.deviceinfohw

When you open the app, you arrive at the "general" tab. From this tab look for a listing called "Touchscreen". To the right it will read either BOA or LG, if it reads LG, your display may develop this green tint issue later on. Mine hasn't developed any sort of issue, but mine has a BOA display panel.

So my screen definitely looks like it's burning out or the adhesive is changing!

I now have dark sections on white backgrounds. Was going to wait for a decent batch to come through but now I'm definitely getting this one swapped out sooner rather than later!

I just got my first replacement. Both the first and replacement have this issue from the moment I turned them on. LG displays on both of them.

The technician in Carphone Warehouse here in UK told me that there is no point in ordering a second replacement right now as this will be from the same batch. He suggested to wait for an official report for Huawei and to try ordering a replacement towards the end of the 30 day period.

The thing is that only my making this widely known to all we can force Huawei take action sooner. We have to post the issue to every possible forum, or social network in order to affect the reputation of Huawei not only in our eyes, but in the eyes of their competitors too.

Does anyone have a dark grey full screen image I could open on my phone to test this I've tried xda app etc but I still get the white bar at the bottom. Plus it would be good if we could take pictures with the same background for comparison.

Also I don't know if I'm doing something wrong but I've turned my brightness down as far as it will go and the phone doesn't go very dull. All images I've tried show as a very light grey. It's there any other setting I should be changing? I'm sure I'm affected as I notice a tint at the bottom of the screen when watching on Netflix. Bought from amazon so going to give it longer before I think of changing.
[Huawei Mate 20 Pro Questions & Answers] wtabram:

Did the guy at CPW indicate how big the problem was? Clearly lots on here, but then that's still quite a small number of devices compared to the total amount sold.
[Huawei Mate 20 Pro Questions & Answers] BillPil:
When I first got there to ask for a replacement, he wasn't aware of the problem at all. He said that up until the nobody had popped up with this issue. Today, when I went to receive the replacement he must have searched it on the net because he akcoledged than the defective devices seem not to be rare...
[Huawei Mate 20 Pro Questions & Answers] jordand77:
Nope,

Been following this thread since page 5 or 6.

Testing my phone almost daily now, LG 51.

14 Days of daily use and while mine doesn't have green stuff on edges or around the notch...there's a spot on the display about 1x1cm that has a green like colour when using the LCD app test.

That was 2 days ago, now I can see that spot from 0 to 10% brightness on any dark mode app such as reddit.

I know most reports are ranging from " out of the box to after 7days"

Well mine got this after 14 days.

The 1st handset - you can notice it all the time regardless.

Even on the second handset - always noticeable, more so in lowlight. Top would be fine, lower would be a washed out yellow version.

Yeah very similar to my 1st one - no chance I would keep that.

First of all you won't see any issues from a screenshot :D

Second - if an image is black the pixels are off so the issue wont show up.
[Huawei Mate 20 Pro Questions & Answers] __NBH__:
This is mine with a grey background on fairly low brightness, seems ok, the photo makes it look slightly red in the middle but it doesn't look like that in reality. Maybe a touch lighter in colour at the bottom but nothing like the glowing green ones, hope you guys get a better one next time.

Download the trial version of Fenix for Twitter so we have an apples to apples comparison. Put it to lowest brightness too.

couldn't find the trial version on the play store, any chance you could post a screenshot so we can download it and open it full screen?
[Huawei Mate 20 Pro Questions & Answers] daz_2000:
I've just spotted this problem tonight too, first time using it in a very dark environment. Very annoying.

Do we know if Huawei have acknowledged the issue? If so any comments?
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Just Google Fenix 2 preview APK and it's easy enough to find.
[Huawei Mate 20 Pro Questions & Answers] vwite:
Well, I've gotten malware/adware downloading APKs from random website so wouldn't want to risk it but I'll compare a screenshot of the Mate 20 Pro dialer with dark mode displaying on both the Mate 20 Pro and Note 9 to see the difference and maybe of spotify and netflix

Just tried the dialer in dark mode and it's actually funny to see the difference between the grey and black lol.

[Huawei Mate 20 Pro Questions & Answers] vwite:
Some have said it gets bad after a few days, I'd suggest you try all the functions and use the phone very heavily (face ID, under screen fingerprint sensor, triple camera setup, playing a lot of videos, speaker quality, Bluetooth audio quality, call quality, haptic feedback, smoothness, EMUI functions, settings, features, aesthetics in general, battery life, 40W charging, etc.) without transferring all your information of your current phone yet but use it enough so you determine if the phone is worth it for you at the price you paid and then check the screen after 3-4 days in a completely dark room with minimum brightness and dark background (but not completely black so pixels are on). That's what I think I'm doing, mine is also being delivered tomorrow
[Huawei Mate 20 Pro Questions & Answers] misiokicio:
So explain me one thing...how that affects the screen in overall, if u can only spot these screen uniformity in 0 brightness?
[Huawei Mate 20 Pro Questions & Answers] vwite:
It can be VERY noticeable with 0 brightness but it can be still considerably noticeable with just low brightness(i.e. auto brightness turned on and you're in a dark environment), it's just the lowest the brightness the worse it looks and easy way to identify how bad is your display

When the OP6 was announced I bought 2, one for myself and one as a gift for my dad, I compared the screens and chose the best one for him because I knew he was gonna keep it for a long time and I was gonna ditch it in a few months for the Note 9 but for the time I had the OP6 with screen uniformity issues with dark gray colors, it was perfectly fine during the day but I hated it in the night (auto brightness on)

I'm in the U.S. and bought the dual sim model from PDA Plaza. They are in Canada, so you'll get a U.S. plug 40W charger. Right now they're doing preorders and they start shipping between 11/10-11/20. I asked them on FB about the green tint issue and they said that if that is an issue it has a 30 day return policy since it would be a manufacture problem. You can get a full refund or choose to exchange it for another Mate 20 Pro.

Hi all can confirm the issue on a 5 day old twilight modell with lg poled. If I already knew that there was only a bunch of devices with boe screens and the rest from lg i would have checked it before buying. The lg oleds are all bad quality. They never had a screen without tinting, unregularities or burn in.

I bought the device in Philippines General Santos city in the Huawei franchise store in SM Mall.

So check before buying if it is a LG Display or not via the explained app mentioned earlier in this post.
[Huawei Mate 20 Pro Questions & Answers] AndreBernardo13:
Im not sure if there is an indicator if its LG or BOE. Does it have?

UK users who purchased from a Network, what route have you taken about replacements?

Mine came from 3UK online, just spoke with Hauwei support & they gave me a generic reply "if there's a fault you can send your phone to our service centre for repair which takes 10 days"

Bit poor really for a phone only a few weeks old.

Gonna try 3 instead, not sure if they'll entertain me in a store though if I ordered online.

Those of you on a contract who've had replacements, who did you go to?
[Huawei Mate 20 Pro Questions & Answers] w2cfx:
I have been given a replacement phone through JB in Australia (the store I went to were excellent), another LG panel so I'll keep the thread posted. They also said they hadn't had any returned or reported though one staff member had read about the issue.

anyone reached out to you tube bloggers as well ... unbox therapy will cover this **** if you get in touch via twitter etc ... he loves telling manufactures it isnt good enough and speaking for the people ... he done it with the apple charging problems recently and bought that to the attention of people .... flossy carter ... mbk ... they all have a big following im sure huawei would speed things up if bloggers were saying dont buy this device until huawei confirm its fixed etc

Finally today I handed on a very good BOE screen Mate 20 Pro. It look perfectly when display grey @ lowest brightness. But on normal condition and brightness, LG display look better: abit brighter and clearer. If I have to choose, I will pick up no faulty LG screen: better than Samsung Note 9 screen ( my 1 week ex-phone ).
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Don't accept a repair, you have 30 days in the UK to get a replacement device from your provider. I'm unsure if on each new device you get 30 days, hopefully someone can provide some law for that.
[Huawei Mate 20 Pro Questions & Answers] xnpu:
The whole "it's a feature" thing is nonsensical and, frankly, embarrassing. If someone brings it up, ask them why only some Mate 20 Pro's have this feature and not all of them - that seems unfair.

That should shut it down pretty quick, but if you feel so inclined play along and ask them why the hue-feature doesn't match the color of the phone? Which competitors might provide a better hue-feature? What are the best practices to get the most out of the hue-feature?
[Huawei Mate 20 Pro Questions & Answers] buxz777:
its been reported people who have been to a huawei service centre in other countries are getting good screens fitted , perhaps the best option is to get it repaired? a screen swap for a good dispaly or a phone swap with a high chance of getting a duff screen again?

id personally return it and wait a month or two for huawei to fix this problem but more people need to make more noise about it on twitter and get people like unbox therapy on board etc
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Unfortunately because the device isn't being sold in the US, a lot of the YouTube reviewers don't want to cover it. Because iPhones are huge, it's guaranteed views reporting on the issues, with this device not so much and at the end of the day they're running a business based on views.
[Huawei Mate 20 Pro Questions & Answers] jusumgeezer:
I spoke to 3 online chat. They said just return to your nearest store, they will need to assess the problem but will most likely replace it.

I will try to go this weekend.

I purchased from 3 , ring them up and they should offer a doorstop exchange. They also offered me if I wanted to swop to a different phone as I have to wait until 20th Nov for a replacement

I am still waiting a replacement but don't mind too much as hoping it will be a 2nd batch means its taking them so long.
[Huawei Mate 20 Pro Questions & Answers] sevanig:
My theory is that the green tint is heat related.

I have a LG panel and use the dark theme.

I tested this out by letting the screen cool down by leaving it alone for 30mins (with no AOD), then checked with a grey background at its lowest brightness in a dark room.

I could see a light green hue surrounding the edge of the screen, the curved edge made it better/worse depending on viewing angle.

Then used the phone for 5-10mins at 50% brightness (basically letting it heat up), and then tried again, no green at all!!

I believe it's heat related, letting the panel warm up to optimum temperature,

Makes sense tho. I think most people who use the white theme (stock) probably don't suffer this problem as much.

I think i'm OK with this...
[Huawei Mate 20 Pro Questions & Answers] mscion:
