[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
Guys, I have noticed that whenever I pull down the notification shade, there are black spots underneath. It has happened across multiple apps now. The weird thing is, whenever I play with the brightness, it seems to fix itself and for a while the spots don't show up. My screen according to hw device is the BOE variant that ends with the number 61.

More explanation on the black spots, they are like shadows. It's very hard to explain but, imagine your hands are dirty, like lets say with oil, and you smeared it all over your screen.

On the right side it's seems to be very visible and on the other side it's very light but still visible.

Anyone else noticed this?

Edit: https://youtu.be/EiJt4zvXUXQ

This video showcases what I mean. Apparently, identified as brightness artifacts.
[Huawei Mate 20 Pro Questions & Answers] hendogg_af:
I have had Boe for 2 weeks now. Haven't noticed this. Huawei needs to get their shiz together though.

mine seems slower after update to .126 and .146. Wiped cache and facial data bit still slower than when I was on .108. Screens don't affect face unlock I wouldn't imagine.
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
Okay I found a way to replicate it, it seems to happen both in youtube vanced and normal youtube. The way to do it is, click on a random video, play it. Switch to landscape mode and then pause the video, then go back to portrait mode. Then pull down the notification panel. And look underneath it.
[Huawei Mate 20 Pro Questions & Answers] samb42:
I have noticed it on my BOE screen when I use the Sky Bet app and pull down the notifications. In the system update thread someone posted the changelog from twitter for the 166 update which is being rolled out in China.

https://mobile.twitter.com/ClubHuawei/status/1073199538519736320?s=19

Under the system changes it states that fixes the problem of displaying black screen or a white screen when viewing some interfaces. I'm not sure if it's related but could be.
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
What is going on:confused:

Is it a hardware related issue or a software related one? It's not consistent throughout the whole interface, yet I did a test in the stock photos app and it happened there aswel. Albeit really faintly, but definitely still visible.:confused:
[Huawei Mate 20 Pro Questions & Answers] Spood:
It looks like a software one tbh.

If it was hardware you would see those spots all the time because the pixels would be defective.

I personnaly only use the dark theme and havent noticed this.

However I did notice some kind of uniformity issue at brightness 0 on gray/dark colored content, there seems to be a while vertical "line" (more line a spot, not an exact line, but it goes from top to bottom) that gets darker than the rest of the screen.

However this only appears in these specific conditions. Even at brightness 5 it does not happen anymore, soI wont call it an issue, probably just the very low voltage not being evenly distributed to each pixel. This is way less noticeable than any hulk that has been posted here, and the observation conditions are even less realistic.

BOE screen btw.

Also, while the battery life is insane, and the fast charge amazing, I do feel like I'm not getting as much out of it as I should... BOE screen on update 146 (which many people reported made battery drain worse than before). Are there any settings to turn off to get better battery life ?

Also does the AOD count as "screen on" in the battery consumption details ? It showed me 7h40 of screen time but I dont recall using it that much. Or is it actualy that good and I wasnt paying attention because it was mainly for setup and updates...
[Huawei Mate 20 Pro Questions & Answers] BillPil:
I had 3 devices with LG panel before this last one that has BOE. All three with LG were showing these brightness artifacts you mentioned. I remember it was the most noticeable when I used the YouTube app with the dark theme.

Thankfully the last device with BOE display (18B15) does not have this issue.
[Huawei Mate 20 Pro Questions & Answers] vanillaLVL:
Just got my replacment unit and its 18B19 , and its BOE on a first try :D ALTHOUGT i joined this replacment fest late , so no wonder why huawei sended me BOE , because its well know problem now for sure , but this BOE display seems about same quality as LG and will see in upcoming days what will happen with it :)
[Huawei Mate 20 Pro Questions & Answers] colts187:
So update on my situation. I emailed some director guy with Huawei that was given to me on here and the Singapore Huawei finally responded to my query. I sent them my info and I haven't heard back but hopefully they let me mail it in to Singapore for replacement that's my best bet at this point. :D
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
So, I should also head back to T-Mobile and ask for a replacement. I have the 18B13 variant.

Help guys!

Hey guys!

I had mine for just over a week, serial number 18A16 with an LG display (the one ended in 53).

At first I thought that the fact that the pannel uniformity is not that great would not bother me that much, but then I saw that when I have the brightness at minnimum, it gets more noticeable than I would like.

Do you think this would be enough to ask for a replacement and start the gambling? Everything else about the phone is just perfect.

I attach some pictures of the screen at medium and lowest brightness.

Thanks!

If you get a replacement in huawei, make sure you check the screen, some units come with scratchs, be careful
[Huawei Mate 20 Pro Questions & Answers] Kermeet:
Hi guys, I returned my phone with LG screen and Hulk, and bought another one with BOE. It's a great screen and is on par with the LG as far as I remember it, the only concern being its a very slight greenish tint when viewed from an angel (which is actually how it's normally looked upon). Do you think it's a defect or a normal thing? Thanks!
[Huawei Mate 20 Pro Questions & Answers] trigos9421:
i found yesterday an stuck green subpixel in the edge of the screen.

I know is not a big deal but i constanly looking at it, software fixing didn't work, as long as green is required in the pixel i see it, so you can't see it in red or blue colour, just in green or in any combination of colour it requires green, the less bright the display is the more the dot can be seen

Is there any possibility huawei replace the screen or exchange the unit?

I'll post a screenshot as soon as i can.

Sorry for bad english

Edit: zoom is set to x2

If i really hard to try closer, i kinda see 2 pixels instead of one, hard to explain bad english :(, just like they were 2 circle but too close, so they seem like 1 but if u look closely you see a distort in the dot
[Huawei Mate 20 Pro Questions & Answers] Biggenz:
Huawei is sending me an 18A26 replacement, having waited for 3 weeks. They said they had to wait for new stock, but I'm seeing people with 18A31 units so surely this isn't the newest stock?

Does anyone know if the 18A26 units are ok?
[Huawei Mate 20 Pro Questions & Answers] trigos9421:
fail post delete pls
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
Well l, just had mine replaced with a 18b23 variant. Lets see how this one is gonna do. Will post updates.

Well, the problem still persists. Dammit. At this point I think it's a software problem.

People with a newer device should test to see, if it still remains. Only then can we conclude that this is a software issue.
[Huawei Mate 20 Pro Questions & Answers] jizang:
So I got mine now and checked the display its a Boe, one question where can I see which batch it is?
[Huawei Mate 20 Pro Questions & Answers] crossdeath:
Check your serial number. But since it's a boe, you'll most likely be fine.

---------- Post added at 01:36 PM ---------- Previous post was at 01:33 PM ----------

Damn this looks bad. Ask for a replacement.

---------- Post added at 01:39 PM ---------- Previous post was at 01:36 PM ----------

Maybe not, devices manufactued as late as 23.11. are still showing signs of hulk.
[Huawei Mate 20 Pro Questions & Answers] mrbeem:
Which issue are you talking about??
[Huawei Mate 20 Pro Questions & Answers] TomSmith001:
Have they started using boe on l09 models now and do you think this one will become green too?
[Huawei Mate 20 Pro Questions & Answers] fuzzybearcow:
Received my third device today, serial 18B26, BOE screen, doesn't seem any different to the last two LG screens in regards to brightness or colour. It came with a full one time use plastic protection wrap unlike the previous two LG devices so felt like a 'proper' phone which is nice.
[Huawei Mate 20 Pro Questions & Answers] nikooe:
I got tired of waiting and multiple replacements and I just got myself a Mate 20x!

Honestly, I couldn't be happier. I'm glad I had issues with the pro.

For anyone else who's looking for another phone, the 20x is amazing.

Just my opinion.
[Huawei Mate 20 Pro Questions & Answers] Frontfiringspeakers:
I honestly thought that there wasn't anything really wrong with my display. You cannot detect any bleed in normal light. Even in total darkness its not too bad. But installed the screen check app and took a photo with my note 9, and got this. Ouch taking a photo really shows up hulk.

Replacement I take it?
[Huawei Mate 20 Pro Questions & Answers] denzel09:
LG or boe?
[Huawei Mate 20 Pro Questions & Answers] Frontfiringspeakers:
LG, it was a pre order phone.
[Huawei Mate 20 Pro Questions & Answers] Pr20:
If you can't see it in regular use, does it matter? Genuine question. I have one on the way here in USA and I'm wondering what do I do if and when I come into your situation. I always use at half brightness. I don't know if it matters or maybe it gets so much worse and then is a problem in regular use? I don't know.
[Huawei Mate 20 Pro Questions & Answers] Rogero:
LG to BOE, glad i replaced it

Just sharing my one experience here after having the phone from Day 1

( 2 x M20P actually, mine and my friend's, both same batch, LG screens with same problems )

I had the phone from first batch in Lebanon/Middle East LG screen Serial 10A (October) and i thought it was perfect, nice screen, colors, resolution , etc..

then i started watching the Green screen issue online and especially here on XDA, i didn't care much and tested mine which showed very little shades of Green on the sides which i though this is normal and i can live with it no problem, after almost 2 weeks of using the phone i started noticing the green shades more and more and also started to appear from the Top of the screen too, especially on the Dialer screen (in Dark Mode, where the Gray/Black background shows it clearly) then i installed Screen Tester app and tested it in the Dark and that was the moment i called Huawei asking for a replacement because Hulk was really taking over my screen.

after almost 15 days, Yesterday we went both (me and my Friend with the very same experience) and got 2 new phones from Huawei Service Center Lebanon, i was worried about the reports saying that BOE screens were not as vibrant and nice as the LG ones, anyway it was a risk we had to take, the New phones were from batch 10B (November) and both have the BOE screen, and i tell you guys, the new phone screen is by far better then the old one with the LG, the White color on the BOE is true white, Brightness is almost the same but something we noticed clearly while comparing both the old phone (LG) with the new one (BOE) using the very same wallpaper, the BOE shows much more detailed pixels on the very same wallpaper, it seems like the Sharpness level is much higher on the BOE screen then the LG, also we can see the LG screens having a clear yellowish tint on white pages, all in all, i am so glad i did replace it, so for those thinking the phone is fine with the LG screen from the first faulty batch i advise you to replace it with a BOE screen phone for a much much better experience, also we tested both new phones with Screen Tester app on lowest Brightness setting, and now the screen looks all black and dark and no shades of green or any light bleeding on the edges.

Cheers.
[Huawei Mate 20 Pro Questions & Answers] Biggenz:
I've just received my replacement from SBE. It is NOT a new phone. It clearly had the display replaced as the display is flush on the one side, but there's a gap running along the whole of the other side where the glue between the bezel and the display is visible. I'm trying to ring the service centre number but it just dies. Absolutely f*cking raging!!!
[Huawei Mate 20 Pro Questions & Answers] djBarren:
This was my replacement. I've aired my voice on her a few weeks back that I think all replacements are refurbished phones.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
Pictures? I'm about to send my replacement from BOE back because my replacement still has green screen issue (not hardly as bad but it's there and I'm not paying for a defective phone). Wonder if there's a way to make a hidden mark on the one I have and see if I get it back.

I guess it's easy to just repair two phones and swap them so both users think they're getting a new IMEI.
[Huawei Mate 20 Pro Questions & Answers] Biggenz:
I'm sick of dealing with these incompetent clowns. Three weeks of my life wasted getting nowhere with them. I will get another replacement, sell it and buy something else.

Hi again!

Okay, so I just got back from the Huawei store here in Barcelona and they told me they are going to replace mine (Midnight Blue, Dual Sim) as soon as they have stock. They said that it will be a matter of days, around one week tops.

The lady there told me that if I bring the box and all the accessories they will just give me the new one. I asked about ir having the plastic wrap and she said that the phone they give don't have it because they are 'tested' before handing them.

In theory everything is fine, but I can't help but thinking that maybe that's how they slip refurbished phones (although she stressed that they -Huawei- thought about that but instead opted to just replace the faulty phones with new ones).

We'll see...

I will keep this updated!
[Huawei Mate 20 Pro Questions & Answers] @home:
Surely the IMEI will be different?

I sent mine back a couple of weeks ago & the IMEI & Serial number are different, So I defiantly got a different device. I was told on the phone by Huawei it was a new device.

[Huawei Mate 20 Pro Questions & Answers] jizang:
So I just checked my screen and I don't quite understand if my screen is faulty or not the first Pic is from the testing app everyone uses here and the second one from YouTube a black screen.

In the app it looks a little green at the top but in the YouTube app it is perfectly black without any green.

Can someone tell me if my screen is faulty or not?
[Huawei Mate 20 Pro Questions & Answers] steadly2004:
Doesn't look bad at all, actually looks great.

But if you took a screen shot and didn't take a picture with a second camera we won't see it at all with the upload, as screenshots will record the what it's supposed to show, not what the screen is actually displaying.

[Huawei Mate 20 Pro Questions & Answers] sketchyterry:
I was promised I would get mine back last week, having sent it two weeks ago last Friday. But I never got my replacement. I was promised I would definitely without a doubt get it this week but so far nothing. I was also told they would escalate it and a senior manager would call me to help my case as they claimed it was taking longer than normal. None of that happened. Anything support tells you is basically a lie. I got my doubts I will get it back this year. I would hold off sending it back for now.
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Not had much time with it yet; but all I can say so far is that after using two previous Huawei devices and a couple of Samsung phones it is like going back to an iPhone, but obviously Android, I think it's because it just works.

Like software wise, it's so slick and there doesn't seem to be any stupid glitches like EMUI has! One major plus is the AOD display, notifications are soo much better it's nice!

Only negative is battery life, but I knew that would be the case coming from the king of battery life.

Will do. Was chatting to another user who moved from mate 20 pro. She loves the xl and says the battery life has improved the more age has used it. Headed now to order it. I'll have it Saturday. Did u opt for 64gb or 128?
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
Ah, that's promising then. My network only had the 64gb variant which is unfortunate, but with the way the Pixel's storage works with Photos/Videos and the unlimited back up with Google Photos I think I should be fine, you can set it to remove Photos/Videos off the device after 30/60/90days, so it should be fine.
[Huawei Mate 20 Pro Questions & Answers] w2cfx:
I recieved my replacement from Huawei two days ago, sealed in its packaging (though they forgot to send me the case they promised as consolation I don't like flip cases anyway). It's B02 and finally a BOE screen. Colours wise it's great, don't think it's any different to the 4 LG screens I had (for reference I find Samsung displays just a little oversaturated, this sits just behind them). Uniformity wise it's as good as any of the many OLED displays I've owned. Haven't noticed any difference in battery life - it was amazing with the LG already (which is the only reason I didn't demand a refund and get a pixel 3 xl or wait to see what Samsung does next year).

Still, my first and second LG screens only had barely perceptible green hues at this point so we'll see how we go.

Based on my experience
[Huawei Mate 20 Pro Questions & Answers] BlueMeany68:
I sent my back , 3 UK dual sim, on Tuesday 11th December. It didn't arrive at SBE until Friday 14th.

Online tracking has been at "with repair engineer" since that point. Nothing else has changed.

Just curious how you guys are 'exchanging' to different phones? Are you going back to the network and complaining? I'm not prepared to pay monthly cost for a phone, I'm with 3 UK. I've actually bought a honor play to tide me over until the Mate 20 Pro returns... seems like a nice little alternative (although camera is naff).
[Huawei Mate 20 Pro Questions & Answers] djBarren:
Couldn't do it. Looking at both side by side I preferred the Mate. Man oh man. I'm worse than a woman in a shoe shop.
[Huawei Mate 20 Pro Questions & Answers] maverick1103:
I was offered an alternative after 2 faulty handsets, I gave Huawei one more roll of the dice and then changed handsets. It did take a phone call to the complaints team as when I reported my 3rd one faulty they could only offer me a phone I didn't want, so after a phone call I managed to agree the phone and a tariff, which does cost me £6 more a month but that's because of the tariffs cost more.
[Huawei Mate 20 Pro Questions & Answers] merewood bebox:
This is an absolute joke ffs. They should just send new phones with DPD replace or something. They know this problem exist. Spoken to Huawei and they confirmed I'd likely get it back in January. Offered me to wait till then. But I don't wanna crack or scratch my phone in that period.

To be honest I think its software issue as another member noticed it his first lg panel then his replacement lg panel and on his third BOE panel.

Hopefully when the update drops it resolves the issue.
