I have this too. BOE screen. Must be a software issue since it only happens in YouTube app.
[Huawei Mate 20 Pro Questions & Answers] From0toHero:
I mentioned something very equal to your issue. But relax. I own the note 9 and the grey background is much more a dark grey than the grey used on the Huawei. The grey Huawei chosed tends to look strange after transitions of portrait to landscape. You can exit the app and enter again. This will make the grey uniform. It's more a calibration issue. Because else the display is perfect. Almost perfect. And after 10 different screen protectors I finally found one who fits and hold well.
[Huawei Mate 20 Pro Questions & Answers] charming.arpit:
I had LG display earlier and it also had the same issue. Also my current BOE display unit too have this. Definately something to do with software..
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
Yes, it has to be a software issue. Just had mine replaced. The same issue persists. 18B23.
[Huawei Mate 20 Pro Questions & Answers] stuclark:
This seems to be a software issue as it doesn't happen in every application; and looks worse / acts differently in certain ones.

I can certainly reproduce the issue when pulling down a notification in YouTube - the screen portion which darkens does not do so uniformly; but on repeatedly pulling down the same notification whilst watching the same video, the location of the non-uniformity moves around the screen. (I can also reproduce the issue by pulling down a notification while watching a video in Firefox)

It seems to me this is an overlay bug; almost a transparency issue where the software is trying to apply a darkening to an area of the screen (the background area not covered by the notification pull down) yet it is not processing the changing images *under* the darkening correctly.

To test this theory; set any static background in any static app and pull the notification down - it will be uniformly darker under the pull down....
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
No, you're absolutely correct. I stated this on another thread also. I exchanged my older device for a newer one, and it still persists. This has got to be a software issue, that I'am pretty sure Huawei can fix. I'm not gonna exhange my device for another one, as I'am happy as it is now.

It was a little awkward having to see those weird artifacts, as I was afraid, that a brand new phone was handed to me, while it was damaged.

I hope that anyone else that reads this, doesn't panic, like, I did. As it can be fixed it looks like.

Anyway thanks for your input, I appreciate it.
[Huawei Mate 20 Pro Questions & Answers] charliebigpot:
You are totally right on the "don't panic" part, but are we sure that it's a software issue? It could also be that it's a hardware issue and that your new device also has it (not to jinx it, but it would be great if someone can confirm it's a software/hardware issue)
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
It is too inconsistent, it only happens on select apps. If it were an hardware issue, it should happen everywhere.
[Huawei Mate 20 Pro Questions & Answers] achie010:
It has to do with the show natural colors mode, you can try to turn that off, select standard colors and color temperature 'cold'. It will be way less, but I don't like the colors then, so I turned everything on. 99% a software issue.
[Huawei Mate 20 Pro Questions & Answers] Maxxwell_Rhyno:
That is helpful, I'll try this out as well. Thank you.

Not experienced any abnormalities with my screen, although I don't use the official YouTube, I'm using vanced.
[Huawei Mate 20 Pro Questions & Answers] luvdog1st:
It has to be a harware issue. My screen on low luminosity is not keeping up on the scroll on ANY application, the color shifts and greyes out. Definitely not software. Also my eyes hurt when scrolling on normal luminosity, a issue that's not happening on my op3t, or htc u11
[Huawei Mate 20 Pro Questions & Answers] beastlyhax:
I have the same issue, it's been an absolute nightmare to deal with. The company I bought from claimed they can't find an issue even though it has been through "thorough testing", what a load of BS. I contacted huawei who asked me to get the phone sent back to me, and send it in to them.

Luckily I recorded video, just can't post here due not having enough posts.
[Huawei Mate 20 Pro Questions & Answers] charliebigpot:
I got a BOE display and just tried what's mentioned in previous posts (grey wallpaper, auto brightness, dark room, flashlight to the sensor). The brightness adjusts in several steps but it's uniform, just a bit darker on the edges depending on how I hold the phone.

Weird, that would mean that it's a hardware issue, not software as somebody mentioned earlier.

Did you notice it from day one or a only later?

That's a manufacturing problem, I think. These screens should be consistent and they're should not be so wide variation between batches. They should be consistent.

Major smearing problem graphical glitch on mate 20 pro

Hi guys new here and new owner of a Mate 20 pro, BOE screen.

I'm having this problem of graphical glitches when scrolling through the gallery or any app that supports a sideways scroll (chrome tabs for example) issue is darker images smear a dark patch/reddish glow when scrolling, doesn't happen or isn't visible with lighter colour images.

I'm thinking software but it's pretty hectic. Have screen recorded for everyone to see, how do I add to this post?

Thanks, Mike

Compared the LG Mate 20 Pro with my Note 9 using the screen tester app and the difference is night and day.

Note 9 is pure black at low brightness whereas the mate 20 pro shows green on most of the screen. Disappointment with Huawei, quality is not there yet.

I think i got screen issues on BOE as well although it's very edge case. Should I be alarmed? Cannot attach image yet.
[Huawei Mate 20 Pro Questions & Answers] PVRP:
And what about uniformity, solid whites and grays, I have handled two mate 20 pro, from stores and I notice in whites the one thing I don't like about oled, a shade of warm to cold white a long the display (diferent ways from one to the other), when it should be equal.

I'm very picky with it, I replaced my older s7 edge 3 times because of this (lack uniformity in whites and grays).

I think with mate 20 pro would be the same lottery of getting one near perfection.

Don't spread nonsense. 99% of LG screens are no good. I just can't see it. Maybe you're just color blind and think you see something
[Huawei Mate 20 Pro Questions & Answers] ccl2003:
Sorry mate but I don't see any difference at all after using both panels. I know you've been reading such bull crap here but its only a figment of their imagination. If only we're in the same country/region then we can compare our units and see for ourselves. While both panels have had some issues the notion that there is a quality gap between the two is a total nonsense.

Just had the horrible green LG screen replaced at a Huawei service center nearby. Took all of 30 minutes to get the BOE screen. Great service!

Update: Also the fingerprint and face recognition now work like a charm, was hit and miss with the LG screen.
[Huawei Mate 20 Pro Questions & Answers] mike2518:
Hey, what difference, if any, do you notice in the screen quality between both panels? I have a BOE and I love it, but then I've never had the LG so I can't compare.
[Huawei Mate 20 Pro Questions & Answers] blackspp:
Screen colors were a bit more punchy but I like the BOE better in fact, more natural, less saturated.

And 8 hours later I'm 100% convinced that also the fingerprint and face recognition is far better. No more misses!
[Huawei Mate 20 Pro Questions & Answers] mike2518:
Good to hear, absolutely no issues here as well! Best phone I've ever used, and I sweared not to ever use a Huawei device after my mate 10 pro experience. Emui had issues back then, Bluetooth was wonky,.... They've fixed all those issues in EMUI 9
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
Crappy panel, green hue on the right edge and they refuse to exchange it as they say it is normal for curved screen and it isn't defictive. Coming from a note 9 and never had this green hue in the curves!

Only visible on light backgrounds on dark backgrounds you can't see it. It is so annoying. I learned that this happens when you buy a Chinese product. It's a lovely phone but terrible service and product quality control.
[Huawei Mate 20 Pro Questions & Answers] webpatrick:
What happens if you lift up the right side of the phone and then at that angle take a picture. Cause I really think this is because of the breaking of the light due to the curve. The green hue I had on 3 previous LG displays at dark circumstances was far beyond the curve in my situations and much more disturbing than this, which i also have on my BOE screen.
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
It goes away if I tilt the device. That what they said to me but I look to my screen straight ahead and not at angle.

They really screwed up the display on such a beautiful snappy device. If they can't just do the curved screen right why not stick to a flat one it really boggles my mind.

Hopefully p30 pro fixes that

Today I am 49 days old with my BOE 18B26, and the problem of inconsistencies is happening outside YouTube, now while I watch a video and a call comes from a contact without a photo and therefore shows a solid color, the color starts to show incosistente, which are removed in 4/6 seconds, is very annoying, someone else happens?
[Huawei Mate 20 Pro Questions & Answers] Darkat70:
Interestingly I was getting similar issues with XDA forum, huawei video and YouTube. See image of huawei video below, but the odd thing is that I removed the Power genie to stop the auto dimming in manual brightness mode, this has also fixed the background colour issues too. I have no idea why. But I'm not complaining. ?
[Huawei Mate 20 Pro Questions & Answers] bastienff:
i am getting the same problem but just noticeable (for now) with a game called "math", it have a blackish background...

i am not sure of uninstalling powergenie because there is no going back after right? it is not like deactivating it.

i love the phone, but the screen thing problem is bull****, i am always afraid there will apear some screen problem, really a crap experience for a highend not cheap smartphone :/

If you uninstall it you can always reinstall via this command:

I have the exact same issue, really quite noticeable when viewing a light screen straight on, disappears when I tilt so I assume it is colour shift on the edge rather than gluegate. More noticeable on the right but slightly on the left. May be the photo but I think mine looks slightly worse than this.

I am still within 14 days so may just return it, not sure yet.

Anybody else got this on their BOE screen?
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Just checked a friends (also boe screen) and it was exactly the same. This would therefore seem to be a characteristic rather than a fault.

Just need to decide if I'm happy with that or not now.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
If you can return it for a full refund I would. I'm currently in a situation where if I want a full refund and to send the phone back I'm going to have to get a solicitor involved which is even more grief and aggro. As much as I love the cameras on this phone. It's pure Chinese trash tier quality and that won't change.
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Here is mine.

I guess I'd like to know if it is worth trying to replace or if all BOE screens are like this?
[Huawei Mate 20 Pro Questions & Answers] demon2112:
this is normal, because of the curvage anf light is deflected
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Might be normal for the Mate but the Samsung's do not do this. Yes there is some slight light falloff but no colour shift when viewed straight on.

I'm on the fence as to whether to return or not. Seems to be a characteristic rather than a fault.
[Huawei Mate 20 Pro Questions & Answers] Kipp162:
To me the edges seem okay, but what I can see on the photo a gradual shift up the main display from green to white.

Heres my issue:
[Huawei Mate 20 Pro Questions & Answers] Aslan55:
I went to the Huawei center in Amsterdam, showing them the same issue you have with the greenish tint. And they told me that the greenish tint is normal, based on how you hold your phone.

My biggest issue is that the screen (BOE) isn't uniform. You clearly can see black vertical lines on low brightness with a white/grey background (like Chrome).
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Wow that is worse than mine.

I am wondering if a good non-hulk LG will be the same? Is this just a BOE quirk?

---------- Post added at 03:21 PM ---------- Previous post was at 03:18 PM ----------

Mine seems uniform but it is noticeable in what I would consider normal use, when for example I am using any app with light screens the green is there, mine is worse on the right than the left.

As I said above I wonder if a good LG (i.e. non-hulk) will also be this way?
[Huawei Mate 20 Pro Questions & Answers] Aslan55:
It is very difficult to find a good working LG screen as most of the faulty screens are replaced by a BOE. The manager at the service center told me that they give the priority to BOE screens as they don't want to risk with more faulty screens. BTW he also told me that the percentage of faulty LG screens for Western Europe lies between 25-30%. For BOE it is between 10-15%. I am really considering to replace my Mate 20 pro for the Galaxy S10+.
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
After intense research and visiting 4 stores.

LG DISPLAY HAS THE LEAST GREEN HUE EDGE ALMOST LIKE THE NOTE 9

EVERY BOE SCREEN HAS VERY STRONG GREEN EDGES AND MORE NOTICABLR ON THE RIGHT HAND SIDE.

lovely phone camera battery and size everything is perfect about this phone but crappy trash cheap display.

Most Boe screen are not uniform and can shift in areas in the screen from white to blue to green to pink. It is very visible in the Grey's and whites on the keyboard.

Just wanted to say that I had some strange graphic issues, but I removed the Power genie from the system to stop that annoying dimming in manual brightness mode. Now I am seeing a lot better graphics no more issues.

Not saying that it's going to work with every phone but it has for me.

The BOE screen on mine is fine. I do see the odd vertical bars on a grey screen but it's minimal and even my note 9 has the odd issue with a grey screen too. Guess it's just an AMOLED issue. No green on mine either.

Honestly the BOE screen is near identical to the market leader Samsung.

I am very happy

Even my note 9 has a slight green tint when viewed at an angle and that's the best screen out there . It's just an AMOLED thing...

Yeh i agree, my BOE screen is great, comparable to my Note 9 screen which has a slight yellow tinge to it when compared to my Mate 20 Pro. Still need to sell my Note but haven't got round to it. Its a great phone just too big.

[Huawei Mate 20 Pro Questions & Answers] Mosman12:
I am not saying that every single screen is like this.

But a company production with so many defects is buying a product with hit or miss and I can tell you the ratios are high.

I don't have numbers but me myself. 3 devices were faulty and 3 on display faulty.

6 devices that I came across are faulty. When you buy a product you expect it to flawless with somehow sometimes defects.

But what is the odds of me getting a flawless device very low from the 6 devices that I came across. Good for you that you have a nice flawless display.

If you went through 6 devices and still couldn't come across a perfect display you will understand how I feel for almost a 1k $ device.

Cheers

I can't say anything else but this boe they swapped in is perfect, no spots or glitches. The tech that did it did say that this screen would be perfect so maybe Huawei woke up? Or I'm just lucky...
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Interesting that there are some good ones out there, as I say I compared my friends and it was the same. I just cannot unsee it now and with my most used apps having a light background it is there all the time.

I have started a return with o2, not exchanging as their process is just slow and convoluted (it would take 2-3 weeks to actually get a a replacement), I have also contacted Huawei directly asking for an exchange so I guess we'll just see which one happens first. Reluctant to return it as I got the £649 o2 deal and buying one elsewhere will cost £899. Back on the Note while I ponder.

Better option is direct to huwaei. You will get a replacement
[Huawei Mate 20 Pro Questions & Answers] Mosman12:
But huwaei don't consider these side green hue as a defect they say that this is just the light reflection on the curve! Or at least in my country they didn't replace it.
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Well Huawei came back to me really quickly, explained the issue and they are sending me a return bag to get it replaced.

As I did explain the issue to them I will not be happy if they then say it is not faulty.

Viewed 3 display models in store today. Hard to judge but 2 were the same or slightly worse than mine the other did not seem to be affected at all other than maybe some slight falloff. This a torture test of course plain white background.

I am starting to think that they will either not replace it or I'll just end up with one that is just as bad or worse.

I am keeping mine until the s10 plus is out and flipping this cheap trash phone for a quality product from Samsung. I love the m20p but I had Huawei for screwing it up. A flat screen wouldn't hurt no one. Even OPPO find x doesn't suffer from that! Can't figure out how Huawei failed like that
[Huawei Mate 20 Pro Questions & Answers] arsenal74:
Here is mine full view. Not perfect and imo not acceptable for flagship but really not terrible.

Leaning towards just keeping it tbh.

Totally agree a flat screen would be preferable.

I still find it in unacceptable.

I sold one and exchanged one, and I couldn't find the perfect screen.

And I find it really distracting with any light backgrounds and since I know it is there. I always notice it. Flipping the m20 pro for an s10 plus or a p30 pro if it has flat screen.

I have the same as you but my green hue is wider but lighter. So many variety of issues and inconsistency. If Samsung has put this phone together with this battery. It would have boomed
