[Huawei Mate 20 Pro Questions & Answers] Nation89:
Right so I've decided I'm not happy with my BOE screen. I'm awaiting the jiffy bag from Huawei to send it off hoping for a replacement. This phone is about 2 months old. It doesn't suffer form the glowing green edges that my LG screen did but what's happening is the green tint at the top quarter of the screen is definitely getting worse, slowly but surely..

I don't want to get another two months down the line and have a device which is green in most lighting conditions so it's going back.

I have spoken to Vodafone and they have been very good. They are allowing me to return the phone directly to Huawei and if I am not satisfied with the replacement they said they will allow me the potential of changing the handset for a different model/manufacturer all together.

We shall see if they stick to that. Ideally I just want a mate 20 Pro that is totally fault free but I'm not sure that there is such a thing.

For reference this is a BOE with seriel 18B22, a batch I thought was unaffected.

That's appalling.

Is this through Huawei or your network provider?

wow.... so huawei still aren't able to install non-defective screens on their flagship devices? smh
[Huawei Mate 20 Pro Questions & Answers] cordonbleu:
It's impossible for all BOE screens to be 100% without issues. A lot of LG screens had issues, more than what you would normally expect. Right now, a very small number of BOE screens might still have some sort of defect. I believe these numbers are the numbers you would normally expect from a smartphone screen. Every display manufacturer has a certain standard deviation and I don't think the BOE screen differ from that. So, when you have a defective BOE I think you're just unlucky and should swap for a new one. The odds that you receive a good one are high.
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
I exchanged my phone twice with batch 10 Jan 2019 and all boe screens were trash.

One with pink color shift in almost half the screen and the other one with extreme green hue on the right side and I settled with the last one best of what I have seen. Green hue on the right side but less intense but it is still annoying and I can still see it in some lighting conditions.

Complete fail
[Huawei Mate 20 Pro Questions & Answers] crossdeath:
maybe try replacing it again? or do you feel you'll get a worse display than your current one?
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
It's directly through Huawei. I think that although BOE screens don't suffer with the glue issue. They will never be uniform unless you're looking 100 dead on. As soon as you get to 1% off center you start getting the green shift. They're just Chinese rubbish.
[Huawei Mate 20 Pro Questions & Answers] Nation89:
The BOE I am returning tomorrow had a faint green mist in the top 20% of the display under very specific lighting conditions (dark room, minimal brightness, dark grey background)

It's got worse though. It's now visible in low brightness levels in the settings menus, Spotify search bar, amazon prime search bar, basically any grey feature at the top of the screen appears green on low brightness ( <20%) .

I am expecting them to send back with no fault found as it's an issue only visible in the instances listed above.

Fingers crossed that is not the case.
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
They actually saying the there is no defect and the green tint is normal because of the curve and lighg falling on it and the problem is that it is visible head on 100% center. It clears when I tilt the phone. Again a big fail for this amount of money they better do it right or charge less

---------- Post added at 08:16 PM ---------- Previous post was at 08:11 PM ----------

The green line along the side is visible when I look dead center to the phone. It fades when I tilt the phone. The failed the curves screen. And it is not only me. A lot of people are accepting those defects from the curves being green to the pink tint in parts of the screen to not being uniform on low brigthness and Grey background. To many issues with the display

I bet you will at least have one of those defects if you start to look closely.

I will live with the phone till maybe the s10 plus is out and surely flip it and never look back.
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
So does anybody (LG or BOE) have a screen that does not have the green edges? I have posted over on another thread. I have BOE with the green edges viewed straight on (they disappear as soon as you tilt the phone)

Interested if there is anybody who does not have this on theirs? I am weighing up an exchange vs. just giving up and returning it.
[Huawei Mate 20 Pro Questions & Answers] cordonbleu:
This seems normal for the BOE. No need for exchange, as any other will have this. The curvature and/or light refraction is different compared to Samsung displays, which causes the BOE appear to have this slightly green edges. It's just the refraction you see. Unfortunately on BOE's displays it's more visible than on Samsungs displays.
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Thanks, I wonder if a good LG one has them too?
[Huawei Mate 20 Pro Questions & Answers] chiffa_ua:
Can this problem resolve itself or 9.0.0.183 update fix it? My phone had really bad green edges with dark areas and green flashing on a lock screen with fingerprint reader not working. I organised return and was about to post it back, but then realised that for the past few weeks it was actually OK.
[Huawei Mate 20 Pro Questions & Answers] crossdeath:
That pink shift is a bigger issue than the green edges imo
[Huawei Mate 20 Pro Questions & Answers] steadly2004:
That's normal with the polarizer of the screen. It's the same shift you'll see with a white background and tilting the phone to an equivalent angle created by the curve. Only Samsung has really defeated this issue. My Pixel 2 XL had more of a blue shift.

Here is an read about why they use a polarizer.

[Huawei Mate 20 Pro Questions & Answers] phil999:
I agree on the fingerprint reader it seems much much better on 183
[Huawei Mate 20 Pro Questions & Answers] chiffa_ua:
Yep, the fingerprint reader is a lot snappier on 183. Also I think they increased brightness a little... Anyway, on the lowest brightness with notifications panel pulled to the bottom I can see a bit of green over the phone dialler, very dull almost unnoticeable. Almost perfect, definitely better than it was before https://youtu.be/yv5fxVpC5Ug Not sure if it's fixed itself completely or just temporarily.
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
I get that some shift when viewed off axis can be 'normal' on an OLED my issue (I too had the 2XL) with my M20 pro is it is there when viewed straight on. You are I guess viewing the flat part of the screen straight on and the edge is off axis. It means that on a lighter screen the green is always visible and quite noticeable which I do not think is acceptable.

I'd like to know if they are all like it. Picture of mine attached.
[Huawei Mate 20 Pro Questions & Answers] crossdeath:
don't you have the receipt?
[Huawei Mate 20 Pro Questions & Answers] steadly2004:
Yes. On mine too, the edge when viewed straight on with a lighter screen, is quite noticably green tinted.

I would say almost identical to your picture.

But it doesn't bother me, as I don't use light colored full screen programs often.

Do we think this glue gate well ever be fixed. I have my doubts.

Green tint

Interestingly, I have early 256GB LG screen that delevloped a horrible green tint, put it aside to decide what to do with it. Buught anoter one in meantime , no issues. Afre a couple weeks, too original , did a master reset

and updates, the screen now is perfect with no issues. Have been using for a couple weeks now.
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
You mean the LG that developed a green tint is fine now after updates?
[Huawei Mate 20 Pro Questions & Answers] ivan552:
yes :D
[Huawei Mate 20 Pro Questions & Answers] blackspp:
I did that, factory reset and afterwards it was just as green. Had the screen replaced by a perfect BOE

[Huawei Mate 20 Pro Questions & Answers] El-Shams:
They changed my phone twice before getting an issue free screen.

I am thinking that I may just return it and wait for the S10. Have a feeling it could be a painful experience trying to get a good one.

Visible with the pure eye on grey and blue backgrounds also sometimes on red.

Any suggestions?

It's a boe screen btw already got an exchange for my other device with LG screen

Till now it's seems a little bit worse but I'm not quite sure.

I will give you an update tomorrow.

So far I got 3 h 15 on screen with 2 hrs of listing to music, Facebook and WhatsApp but only a little bit of the last two. My brightness was set to very low.

Got 67%% remaining till now.

UPDATE:

overnight I lost 4% with airplane mode on. Definitely more then before - especially considering, that my night was about 6 Hours long without touching the mobile.

Since then I lost 5% more.

So the battery IS indeed not as good as before.
[Huawei Mate 20 Pro Questions & Answers] jadaress1:
That's what is putting me off removing it as yet. I'm hearing conflicting answers on how it effects the battery. Thanks for sharing.

Just got off the phone with SBE. They're sending me a replacement hand set due to the green screen issue mine went back for. It's apparently not coming with the box, accessories etc. Should I be concerned about this being a refurbished phone or has anyone had a brand new device without the packaging.

Thanks
[Huawei Mate 20 Pro Questions & Answers] steadly2004:
I've not heard of one being new without box. But I may just be a freshly replaced screen on a lightly used phone.
[Huawei Mate 20 Pro Questions & Answers] Nation89:
The replacement phone is perfect. I called SBE and they told me it's a brand new device, the serial number suggests that too.

I previously posted on here doubting this phone could have a perfect screen, I was wrong. This one has absolutely no screen inconsistencies on the screen tester app at 1% brightness. The edges of the screen also have zero greenish hue, this is something I thought was a characteristic of the curved screen rather than a fault. There is a very slight grey edge which I attribute to the curve.

After 3 devices I conclude from my experience that you can get a good one, they do exist.

Thanks everyone for their help and advice on this thread.

Mine too has the issue

Version is LG-01-18-10-43

Problem has definitely gotten worse over time. I pre ordered so would presume it's from the first batch.

The issue was only apparent at low light with a gray image but is now obvious all the time

Has to be a hardware issue and not software as it's too inconsistent.View attachment 4632304View attachment 4632305View attachment 4632306

what the hell is going on? wasn't Huawei supposed to be using BOE as MAIN supplier and LG only as backup supplier, why everyone except reviewers seem to have an LG screen, after all other phones that have had issues with LG OLED displays, I really really wanted the Mate 20 Pro to have a samsung one but I only pulled the trigger because I thought it was at least going to be a BOE one since it was supposed to be the main supplier.

I wouldn't worry about the return periods in UK as they have legal obligations under the Consumer Rights Act to replace or refund faulty goods without question for 30 days. The 30 days will reset when you get a new device as it's a new product.

I got mine yesterday. Couldn't really check it out until today. I have the LG screen. Looks good for now. Hopefully it stays good.
[Huawei Mate 20 Pro Questions & Answers] freezingpoint:
Picked up mine last night and out of the box it has this issue.

Contacted Huawei in my country as I'm almost 100% confident the other units in the store will have the same issue.

Will see what they say and will check daily if this gets worse.

It is only visible in lowest brightness, dark conditions, and certain shades of grey. Hopefully it won't get worse.

It doesn't look as bad when I look at it with just the edges having the tint, but when I took a photo of it with a Note 8 it shows green tint on the top as well.

My Pre order was received on the release day (26th) so 6 days Inc today.

Pretty poor really. This is the first phone I've ever pre ordered which was driven by the promo offer. Had there been no offer I'd have definitely waited.

I'm curious as to whether it's just the LY09 model affected as it seems to me that everyone without the issue seems to be an LY29 owner?

wow! .....is all i can say after reading this thread.

Since I have to order one from abroad without any guaranty I'm definitely not willing to take a 50/50 chance that I'll get an LG screen with this ****ty problem ....what the hell is with LG that they can't make a good oled screen, and why did huawei take a chance with them after seeing the mess they made with their first attempt.

looks like i'll be skipping this phone, was planning to upgrade from my mate 10 but now not to this one.

Not so easy getting a replacement in Norway:

I have already changed the whole screen once, and it didnt help. In fact, it got worse.

I went back to the same authorized huawei servicecenter today to get a replacement.

They refused to send it in for replacement, but offered to change the screen once more. If that didnt help, they would change also the motherboard and the screen for a third time (!)

They also said Huawei only replace phones max 30 days after purchase.

I then contacted Huawei support and they said have never heard of this and said I had to take it back to the store where I bought it.

Theeeeen I went to that store and finally got some help. They had talked to Huawei who told them to send inn all phones with green screens. Only problem now is that the store uses the same servicecenter who refused me a replacement.

So, now Im back to my old iphone and have no idea if i get my phone back with a new screen or a replacement :/

[Huawei Mate 20 Pro Questions & Answers] acepool08:
After going to a store and comparing their device on display with mine, I have some doubts...

Mine is a 18C28, BOE panel with perfect uniformity and just a slight green tint on the curved sides (maybe you can see it in the picture).

The thing is that the one on the store (18928!) does not have this green tint, but the screen itself is way dimmer at max brightness. I'm assuming this is probably an LG panel (and may hulk on dimmer settings), but it actually surprised me A LOT that there appears to be no burn-in at all. My guess is that they have that device since day 1 and they recently replaced the one they had or something like that.

Now I really don't know what to do. The green tint on the sides is not as pronounced as in my last device, but it's still there sometimes (mainly watching content that has a white background or something like that, then I really notice it). At this point I think I might just stick with this and learn to live with that minor thing since the rest of the phone is absolutely brilliant...
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
I am in the same boat and mine looks the same as yours too. I had a look at a number of display models, most were similar but there were some that do not have the edge shift at all. My issue is I cannot un-see it! Also I have not seen one response on here from a BOE owner saying that they do not have the shift so I am assuming that only non-hulk LG screens do not have it, it seems that all the models out there now are BOE ones so the odds are any replacement will have the edge shift.

I am on the fence about whether to keep it or not. I have a bag to send it to Huawei but I am convinced they will just say it is normal and no fault, so it is either return it for a refund or live with it.

The S10+ has me curious especially the ceramic one and having a proper functional always on display would be nice too, on the flip side though there is still a lot I prefer about the M20 pro including a better size, proper face unlock, expected better battery and the S10s main camera looks to be the same as last year which really surprised me
