Offical Huawei Norway now say they only change the screen from LG to BOA and do not do phone replacement anymore.

Anyone else heard about this in other countries?
[Huawei Mate 20 Pro Questions & Answers] denzel09:
Hi, i have now the possibility to buy 2 different available Mate 20 Pro in stock in store near my house

1) emerald green 18C21 Dual Sim L29

2) midnight blue 18C28 Mono Sim L09

Which i can buy to not have problems? Thanks
[Huawei Mate 20 Pro Questions & Answers] acepool08:
Mine is a Dual SIM L29 18C28. Screen is almost perfect, just a bit of green hue on the sides that have me thinking about replacing it again... Not sure though.

I posted some pics before so you can check them out.

Let us know what you end up going for!
[Huawei Mate 20 Pro Questions & Answers] denzel09:
this scares me a little, i think to wait
[Huawei Mate 20 Pro Questions & Answers] denzel09:
Which model is? Mono or Dual sim? And which color?

Atm the screen is still perfect?
[Huawei Mate 20 Pro Questions & Answers] acepool08:
I went back to the service center today and they told me that this green tint on the sides is normal with BOE panels, so I guess I will be sticking with this one (18C28)!
[Huawei Mate 20 Pro Questions & Answers] vandal4e:
this is unacceptable and you shouldn't be OK with that
[Huawei Mate 20 Pro Questions & Answers] Darkat70:
I have a BOE and don't have this issue, I don't see how it can be normal.

And what model and serial do you have? The more info I can gather the better...

Thanks!
[Huawei Mate 20 Pro Questions & Answers] Darkat70:
LYA L09 Single SIM 18B02
[Huawei Mate 20 Pro Questions & Answers] acepool08:
Thanks! And what colour?

I will go there again this week and see what I can get.

Also, I found something else with the screen: when displaying black at low brightness settings, there seems to be some backlight bleeding. If the brightness is set to max the pixels seem to turn off just as usual. I noticed this while watching a video the other day in a dark environment because I could actually see the shape of the screen (most notable in the bottom part).

Again, this behaviour is not typical for an AMOLED screen...
[Huawei Mate 20 Pro Questions & Answers] vandal4e:
it is typical for BOE screens as discussed previously
[Huawei Mate 20 Pro Questions & Answers] Darkat70:
Mine is midnight blue. I've not really noticed any issues other than if I set brightness too low it does get a little difficult to read text, especially smaller or black text on white background, white text on dark background seems to be better.

my mate 20 pro LYA-L09 CUST605 is with screen leakage on the sides at the edges along with the metal housing .. I have already sent the warranty let's wait
[Huawei Mate 20 Pro Questions & Answers] gunggu:
I had not had the problem until I tried to apply a type of screen protector (the hydrogel one that needs to be smoothen with a pad to the screen}, then I noticed that the screen on both right and left edge were a bit greenish and then it turn more green on black/grey background.

But then, after around 2-3 weeks the problem were gone. No greenish tint on both edge anymore.

Until today, i had not experience the same problem, so my guess is its due to the pressure to the screen while i smoothen the surface of the screen protector.

Big Dilemma

Finally got a resolution with my Pre Order Mate 20 Pro which developed the gluegate issue in January this year. Huawei were terrible in trying to sort out the issue as they wanted to have the phone in for assessment and repair / replace but because of their stock issues and customers having to wait 20+ days without a phone, I refused to send it in until they had replacement stock to send back out.

My network provider O2 orginally said if I was within the 30 days of a new contract they would have just replaced the phone like for like but because I was over the 30 days it would have to come in for assessment to see what action they needed to take which again I wasn't happy about because a manufacturers fault like this shouldn't have any detrimental impact on the customer which this would do.

I called O2 again yesterday and spoke to a very helpful representative who took 2 minutes to arrange a swap to happen within 24 hours of my faulty handset for a brand new retail handset including all the accessories in the box. I've got my new Mate 20 Pro coming in the next 4 hours but I have 1 question which is based on the BOE Screen Issues thread on here.

Do I open and use the new Mate 20 Pro when it arrives later this morning Or do I go to my local O2 shop and give the unopened handset back and ask them to freeze my account until the P30 Pro comes out in the coming weeks and change onto that device in the hope that it doesn't suffer with screen issues like the Mate 20 Pro?

Big dilemma!

My local retailer got a new batch. The S/N starts with LHS0219115xxxxxx. Do anyone have any experience with this new batches? Oh btw is this the new date format they use? If yes I guess this one would be 15th January 2019. Right? Thx.
[Huawei Mate 20 Pro Questions & Answers] ccl2003:
Yes, they're the newer batch. Mine is 18th January 2019 and its finally a perfect BOE panel without any discoloration issue.
[Huawei Mate 20 Pro Questions & Answers] acepool08:
Yesterday went to the Service Center and after telling them about the issue with the blacks (displaying black with low brightness produced some kind of bleed at the bottom of the screen, very noticeable when compared to to other oled panels from older phones I have laying around). They told me that since this is not a common issue, they had to send the phone to the technical service.

To be honest, if Huawei themselves replacing the screen and battery of my phone instead of giving me a new one means that I will FINALLY get a perfect one, I'm happy with that. We'll see how this turns out...

Now the waiting game begins!
[Huawei Mate 20 Pro Questions & Answers] buxz777:
Sent my mate 20 pro back ages ago .... just bought another one now they’ve come down in price and I had some vouchers to use .... got a twilight one in the uk and it’s a boe screen and seems good to me

Worth noting the only reason I ended back up with a mate 20 pro is because I got a mate 20 x and the screen was terrible , when I ran oled tools it had weird screen uniformity, weird lines and when I went to unlock the phone it had a green glow coming from the left hand side , going into the phone which is actually what made me check it with oled tools

I took it back and the shop didn’t have stock but priced matched the mate 20x with the mate pro that they did have stock of , I needed up with a pretty sweet deal on the mate 20 pro and one with a good screen ✌️

[Huawei Mate 20 Pro Questions & Answers] miloshsk:
As far as I know, they are not shipping any models with the problematic LG display since the middle of November. All models since then are with a BOE screen which doesn't have those issues. My unit is manufactured on 16th Jan 2019 and has a BOE screen. Very happy with the device so far.

[Huawei Mate 20 Pro Questions & Answers] miloshsk:

[Huawei Mate 20 Pro Questions & Answers] Frontfiringspeakers:
I've had my mate 20 Pro since launch day. It's perfectly fine in everyday lighting conditions (there is no green edges) , but use the screen test app in dark conditions and my god what a difference. My mate has just upgraded to the mate 20 Pro and its has a BOE panel. Just look at the picture difference between the two (photo taken with a note 9, taking pictures with another phone really does highlight if you've issues).

So, that's finally now convinced me to return my phone to huawei.

I bought the Mate 20 Pro on Black Friday (received the 26th November). When I check the phone in the dark, I can see a green tint. I was seeing this tint with Reddit night mode (not AMOLED) but switching to the AMOLED theme generates a true black "color" so I'm wondering if I'm seeing the same issue as it seems the phone is able to generate black. My home screen is rather dark and I can see a green tint... Since I've put the phone in night mode, this tint is pretty much present everywhere when I use the phone in dark environment.

Any idea if this description fit the known reported cases?

[Huawei Mate 20 Pro Questions & Answers] acepool08:
As far as I'm concerned, you should go get a replacement.

Yesterday I went to pick up what is my 4th device and it is by far the best one yet. The screen looks absolutely perfect in every condition (no green tint on the sides, AMOLED level blacks, extremely hight peak brightness, etc.).

It also happens to be from the exact same date as my last one, 28th od December, and (duh) it has a BOE panel.

Will update if anything happens, but I think it's pretty safe to say that 4th time has been the charm for me.

For anyone out there having doubts, I would only say that you need to be persistent and keep asking for replacements if the device does not meet the standards it should for the price point.
[Huawei Mate 20 Pro Questions & Answers] Just a nickname:
Thanks for you reply. How did you proceed with the replacement? You say the 4th time is a charm to you so I'm guessing the first 3 weren't ;)
[Huawei Mate 20 Pro Questions & Answers] acepool08:
Your guess is right.

Just go to the nearest Huawei Service Center and show them the device, they shouldn't say anything other than "we will replace it".

Go for it!
[Huawei Mate 20 Pro Questions & Answers] nick-1988:
I would tell you my sad story around this issue.

1st device - Lg display, changed with another one (new)

2nd device - Boe, but some visible scratches on the back and around the usb port, already present when I opened the box for the 1st time and taking the phone in my hands. Changed again...

3rd device - the same of the 2nd (scratches on the top side... but are they really new as Huawei said?). Changed again...

4th device - BOE display, seems all ok... after 20 days, pink hue on the left! :( You can see from the photos here

Hello,

Last friday, I bought a mate 20 pro with a boe screen.

The problem is that in my device I can see green edges when the background is white or clear. If I try to use OLED TOOLS or Screen Tester I cannot see the green tint.

Is this normal or an issue?

[Huawei Mate 20 Pro Questions & Answers] acepool08:
Ask for a replacement.

My 3rd device was like that and at first they just told me "this is normal".

After insisting and finding out that the display had an issue while displaying black colour, they agreed to send it for evaluation. Then they just swapped it for a new one and is perfect, with no visible green tint on the edges.

[Huawei Mate 20 Pro Questions & Answers] acepool08:
Oh man...

After a couples of weeks with my 4th device and its perfect screen, something started happening. Apparently some of the oleophobic coat has worn off. I attached a couple of pictures (one with a clean screen and another after normal use for a while, bear in mind that this is really hard to pick up on camera). It goes to a point where, obviously, affects the feeling of the display -not as smooth in this area- and that makes the whole experience worse.

I am shocked because this has never happened to me before and I haven't had any weird behaviour with this phone (never used products for cleaning or touched it with anything other than water and naturally greasy fingers).

Went to the store before today and they told me they will replace the screen, which makes me VERY afraid. I don't want to go through the whole process again... Crossing fingers so nothing weird happens this time...

On a side note, the guy at the store recognised me when I stepped in and I could almost hear him think "oh god what now"...

[Huawei Mate 20 Pro Questions & Answers] LuMe96:
Hi all,

Have been following this topic from the distance as I didn't feel concerned up to now. Then 2 days ago I got heavy display issues on AOD first with huge green edges and time not displaying while everything was still ok on unlocked screen. A couple of minutes later artefacts, screen flickering and green tint all over the place. Tried to reboot but no changes. I switched over to my Pixel 3 XL and put the Mate 20 Pro in my suitcase to send it in after my return to home.

Today (2 days later) I needed some information from my Mate so switched it back on and to my big surprise everything is back to normal for a couple of hours now.

Is this something that you guys also experienced?

I'm a bit concerned about sending it in for repair if no issue is visible even if I took some pics but am even more concerned to not send it in.

Thanks for your feedback.

[Huawei Mate 20 Pro Questions & Answers] LuMe96:
Actually, having been in Paris for business last week I stopped by a Huawei Customer Service Center.

Even though the phone was working fine at that time, they changed it straight away against a brand new one (mine was 4 months old) when I showed them the pics.

Hopefully this one will last longer.

Anyway, at least in my case, great service. :good:

Guys, is your screen completely black when displaying black images etc? I mean, for example, if you lower brightness all the way down to minimum and open some full-black image - from definition of AMOLED screen, all the pixels should be off and completely. But in my case, in the dark I see that the screen is not completely black, it's grayish and burned out in some spots. While the burnouts are not that bad, this not-black issue bothers me - if it's normal or not. What's weird, Always On Display works as it should - the screen is off and only the digits are on, so it looks like a software issue?
[Huawei Mate 20 Pro Questions & Answers] Limeybastard:
It depends what black image you are using. Some black images are not true black and have anomolies when shown in a dark room.
