Screen issues! - Huawei Mate 20 Pro Questions & Answers

Anyone else experiencing this? See attached photo. Bottom end of the screen, pretty much half way down and onwards, colours and get lighter at 0% brightness. Top of the screen is black, like an AMOLED panel should be, bottom is light with an almost green tint. Used a screen test app and can see the shift even more and also navbar burn/retention.
Not impressed.
As I ordered this on O2, via Mobile Phones Direct, who do I contact or do I go to Huawei? Only been using the device for a weekend!

Ok so on lowest brightness in a dark room the darks on xda for example is greyer bottom half of the screen. But tbh any oled I've tried struggle a bit at very low brightness on dark/grey colours. Staying that yours does look particularly bad on the bottom 3rd

I have that too in the bottom right hand side of the screen. I already spoke to Sky to get a replacement and they want me to send pictures.

I'm printing out the photos I've taken in colour and including it with me return, keeping them for my record too. They want me to factory reset the device so last thing I want is for them not to be able to replicate the issue. Unsure what tests they'll do, as it's going back to Mobile Phones Direct

That sucks mate. I've not followed screen issues on OLED devices closely across the brands...so surprised this is happening with a premo device. Hopefully there are only 1 or 2 cases for some of these major defects...as many more becomes worrying!

I know right!
Another thing, sorry for off topic is I've switched from Three to O2 (number transferred a few hours ago and now using O2 with old number) and I'm getting absolutely terrible 4g speeds. At work at the moment and signal hasn't always been the greatest on my office, but hoping when I test speed when I leave and also when I'm home that speeds are decent. Otherwise I may end up cancelling this phone and contract, and maybe I'll see about the Pixel 3 XL on a contact back with Three, or maybe I'll go sim only and get the Oneplus 6T - as the likelihood of getting root for this device is looking slim.....

Wait for 1/11, which ius the AUS release date of the phone and an extra week and see if Funky Huawei offer rooted versions of this phone. The hardware by itself is far superior...it's a same there's a lot of bugs and problems letting it down though...and then there's EMUI...

I've had similar issue on mine but it's down the right hand side.. Three sending me out replacement on 9th Nov when back in stock

It looks like your navigation keys caused this awful OLED burn-ins. Use gestures instead of the keys instead.

is there a way to change the background of the keys? e.g. to overlay on the app thats open rather than display on a white band?

Ive got the same issue only just started though which is weird!
if its carries one I am thinking of jumping ship not a massive fan of the curved edges but everything else about this phone wins for me just a shame they didn't keep it flat like the P20 Pro.

Light leaking underneath 3 front buttons of HTC Titan

Just got my Titan a day ago and i notice light leaking between the edge of the screen and the frame, just below the back, windows and search buttons. This is obviously visible when using the phone at dark places. I find it annoying, does your phone have this problem? Should i have it replaced? See attached photo...
Is it normal..

Just to clarify your response, this problem is normal? So i guess your phone has this issue too? TIA
This was already reported in another thread.
I don't see the issue though; it's not noticeable nor is it detrimental. The real problem is that you can't turn the lights off when watching a video; then the entire thing is distracting.
Capacitive buttons suck in general, except for the cool factor.

I still find it annoying. This is on top of one the Windows logo that's brighter than the rest. Hmmm what to do...
Mine doesn't leak under the edge of the screen, although it is brighter in the bottom half of the buttons, so clearly the lights are right at the bottom. If it's leaking under the screen edge, it would indicate that the screen is not quite seated correctly, so could be worth exchanging. That said, it won't affect the functionality of the phone so it depends if you find it annoying enough to send it back. Personally I think if you've just bought a brand new device at £400 odd then you want it to be spot on - on my first device, the little plastic surround around the micro usb port would come loose, and the headset speaker would buzz at high frequencies, so I returned it and the replacement has been spot on (touch wood). Over all, I would say the Titan is a very well made phone.
I think it is normal.
It is normal. I have it also. Underneath and when my brigtness is low i can also see it below on the screen.
Pretend it's the glowing under icons in a mac like dock

No!!!!
It's normal and already mentioned quite a few times. It would have been nicer to not have just the bottom right to be extremely bright but then the whiteness wouldn't have come out so well. It might have been dull. Hope Titan 2 has a smaller LED.
No such problem with my Titan manufactured on December 7th, 2011.

Just like others here I thought it was normal and didn't think nothing of it however due to a recent screen fault on my Titan, it was sent to HTC for repair now it's comeback fixed, they replaced the whole screen and not sure what they've done but the light leaking from between the edge of the screen and the frame is no longer there!
So I guess it's a case of quality control at manufacturing, you'll either get Titan with this issue or not!

Great to know that! I sent back my unit to ebay seller for replacement. I asked them to get me a new unit with no issue - in case all their stocks are the same, it is nice to know that it's repairable!

Yellow Tint

Hello,
I was just wondering if this is a hardware error or software error but my screen seems to have a slight yellowish tint, but the very bottom seems more white.

I'd guess it's because of glue which is used to hold screen and glass panel together. Probably it haven't dried yet. Wait couple of days and screen should lose it's yellowish tint. If not then RMA the phone.

So I ordered a OPX on 8th Nov and got it on 10th Nov, What an awesome device with brilliant Display !!!!
Then my cousin saw it and wanted on for himself, so I ordered another one for him on 11th and got it on 14th ...
But when I saw compared both the phones, I realized that my OPX's display has a Yellow Tint
So after the Moto X(gen 2), Nexus 5X ... The OPX also has the same problem ...
I wonder what might be the reason behind this and why none of the company ever commented on this issue before ????
I want all of you to check your device and see what type of display you have, so that we may be able to conclude which one is defective, and if a particular batch is affected .
Here is the information of my 2 OPX :
1.
Month and Year of Manufacture: Oct 2015
Month and Year of Import : Nov 2015
QC: 2003D
Date : 2015.10.21
Yellow Display : YES

Blue Tint Display On OnePlus X
Using This phone for about 2 days and just found that the whites on the display are bluish in color or i can say that it has blue tint on display when viewed from different angle . Also found that the Reds are somewhat orangish red in color .
Just wanted to Know that is this is Software problem or i have got a phone with defective display .
Maybe it's your personal taste of colors ? I haveQC2006N

I've read about a slight blue tint when looking at the display from an angle, in several video reviews.
I've came here to rant as well, bought the OPX and have used it for a few days, mine also has the yellow tint issue on the top half of the screen (bottom half is a nice white). It is visible on day to day use which makes it annoying. Would've been able to live with it if the whole display was slightly yellow but the fact that part of it is and part of it isn't bugs me.
I've seen possible solutions like using a hairdryer of leaving it on the car dashboard but this issue is not my fault-I shouldn't have to go through **** to fix it. OnePlus better do something about it or I want my money back.
I've opened a ticket/RMA hopefully they get back to me early next week.
On a side note camera isn't as good as it could be, sd card bug is annoying, battery isn't great. My LG Spirit served me better to be honest.

I don't know if it's plcaebo or it really happened. I stay in Mumbai which has a hot and humid climate (40degree is normal for us) and went to a cold place with temperature around -5 degree. I noticed that the screen got a yellow tint but it got back to normal once I got to warmer place. Now it could just be my illusion. Could anyone with some knowledge on this opine on this??

S9+ screen burn in after 4 days

Hi there. Long story short I've already encounter a "mild" screen burn in on my brand new S9+ I receied last Friday. I say it's mild cause it dissapears after few moments but I'm not happy with that on almost £900 phone. Basically when I use AOD in blue and unlock the device I can see a ghost of the clock burned into my home screen. I reckon it's because it does not moe as much as it used to on my S8. Im attaching a short video but its hard to see in on there. And funny enough all it takes is few minutes for it to show up. Does anyone seen something like that before? My only concern is that if it's doing it already after few days how bad will it be few months in? I've contacted O2 to get it replaced but I hope my next one will be ok.

In my experience, screen "burn in" doesn't go away after a few moments. So if it does, then it's not really burned in, and isn't really screen burn in, yet.

That's why I've called it "mild" burn in. I know it doesn't go away cause I've had it on my previous Galaxy phones near the end of first year. This one does kinda ghost behind. I'm having a door swap this morning so hopefully it was just a case of bad batch. Also I managed to get a better video of what is occuring to my device if anyone is interested

Do you also use AOD? If so hopefully mine was just a bad one-off. The thing is, only few minutes are enough to make it seen. First time I wasn't even looking for it, phone was not moved for about an hour and then when I unlocked it it was pretty much black on white, that bad. A lot worse than on that video. Hope Samsung will notice the problem and make some adjustment to how AOD clock moves around cause it's moving nowhere as much as it did on my S8

Got my replacement device this morning and I can confirm that this one does the same thing for me. The question is, am I really unlucky to get a bad batch or is the problem a lot more widespread on S9+?

This is why I very much dislike AMOLED. Sure, it looks pretty but you have to watch what you display, how long you display it, and the brightness of your screen. The Nexus 6 burned in on me in less than a week and that was the last AMOLED device I owned.
I've been debating on trying the S9+, mostly because it's almost impossible to find a decent device without AMOLED these days. Same with glass builds. Yeah, they look nice but they're fragile and prone to scratching.
Seems like everyone jumped on the AMOLED bandwagon and now the glass build bandwagon. It's looking like the notch is next.
ive read OLED screen will have a tendency "burn in" pixels that are always on. need to keep things moving.

Rule #1 never use white **** on AOD
Rule #2 never use white widget
Rule #3 Use Dark theme
im out
Speaking of dark themes are they ever going to have an entire black scheme, system-wide?
I can understand having white themes for LCD devices but I really miss the system color schemes of the jellybean days.
When the S5 came out, for example, the dialer was so damn bright you could use it for a torch! (flashlight)
Ridiculous.
It.Needs.To.Stop.Now
Also, burn in and persistence are different. With the former being permanent and latter temporary.
Hopefully it's not permanent.
I usually disable AOD anyhow.
It's really dim but I feel safer with it gone.

AOD has been designed to keep shifting the content on screen so that burn-in doesn't happen. Not sure if anyone has noticed but I have noticed it on S7E and S8 so far.

PSA: Huawei Mate 20 Pro has a display problem - Gluegate

VÍDEO
https://www.youtube.com/watch?v=smsc_wp_YuI
UPDATE:
OK, now it's a widespread issue.
It looks like it could be the glue drying or something else.
Because the issue appears after some days of usage.
Btw, I've returned my phone
-------------------------
I bought the Mate 20 Pro the 18th of October, at first the display looked fine but it's been some days already that I'm noticing a yellow/green tint on the right side of the display that reminds me so much to the problem that happened with the Nexus 4 (it was because of the glue [https://www.pocketables.com/images/....com/images/2012/12/nexus-4-yellow-screen.jpg) ).
And it's getting worse.
It's not just me, another user on XDA and another user on Reddit also said that are having the same issue.
If it's the glue, even if you don't notice the issue right now on your device, it might appear in the next days, as it happened to me.
These are my pictures:

What do you think?
I'll go and return my phone for another one this Monday. And if the new one has the same problem I'll ask for a refund
UPDATE:
More things I've noticed:
After playing a burn in fix video, the way that this issue looks is different, it changes.
Here I took some pictures of the display with a black background:
https://imgur.com/a/RVscvY9
NEWEST UPDATE:
There seem to be two different issues, or maybe one. Maybe it's related with the display controller

Gesendet von meinem LYA-L29 mit Tapatalk
I'd definitely 100% exchange it or return it if my screen looked like this
Mine is today returned my shop and have new

is there a way to find out if your unit has a BOE or LG display? All of the reviewers said the screen was amazing but LG screens had a lot of complaints on the Pixel

Then it will probably be the glue
if its glue, its a manufacture faulty batch (lets hope). This even happened years ago with Samsung phones due to poor QA (and for Samsung that's huge).
While highly unlikely, if you happen to find its software related or to do with w/display driver, post it in the EMUI/software problem/fault thread so you can let others know. Also, be sure to get in touch with Huawei and keep us posted on your results.
EDIT 1/11: From what I can read on the first 30-40 pages its moistly screens with LG and not BOE. Its in multiple regions, so let's way a few more weeks and see if the newer BOE batches or wave 2 of the shipments fixes the issue...

Yup sending it back to mobile phones direct tomorrow...
I have similar problem. The brighter shade can be visible on both sides ( on the right side little bit more expressive) and at notch edges. I'm returning phone tommorow . Sucha a shame :/
I have the same problems
Following this. I also have the same issue. Not sure though if it's to do with the screen refractions on the curved glass. Will wait to see what happens with others. What apps are people using to test?

I thought that. I've never had a curved like this. I put a black wallpaper on and it's fine. Put a colour one on and you see it
A great way to tell is if you have a white chrome window and then pull the notification shade down it shows all around the notch. I think it's something to do with greys on low light levels?
Yeah greys at low light seem to vary in colour a little, if it's really bad keep swapping the phone. I had to change my Nexus 6P made by Huawei 3 times before I got a good screen. Mine is slightly lighter on the bottom third but it's hardly noticeable so I'm going to stick with it.

I've got the XDA app open and it's green on the left , green around the top and bottom left. Think I hear the 6T
For me it was netflix loading screen,it's gray,and the amount of shade was overwhelming :-/ I'll check another version tommorow,if the issue will show up on another device i quit and wait for S 10 probably.

Be cautious,I saw nothing at first day of usage. I think this issue is getting worse over time.

Mine got worse today. Used a lot today though

Display woes

So i swapped my first device kinda wish i hadent as the screen was great.
New device has green tint anything below 10% (this i can just about live with as i just raise brightness). However i recently noticed in direct sunlight yesterday that i can barely see screen and it tints purple (yes i have adaptive brightness on)
Now something really strange in bright sunlight when a shadow casts across a white screen , the shadow against screen is green has anyone else noticed this ......?
.
hard to capture properly as spare phone is an old iphone but the green shadow is from my hand which can be observed above , also notice how the white tints to purple.

Well the green tint below 10% i don't experience with my phone.
The other notion/complaint, is just natural properties of an OLED panel, all my previous phones had the purple in sunlight tint.
probably the brighter sunlight reflecting in one of the physical layers of the panel. Nothing you can get rid off unless you want LCD.

i have a new phone incoming tomorrow , these are the pictures of green tint (purple sunlight) sounds like something will have to compromise on .. green tint i cant though.

Look, the picture you took in sunlight is normal behavior and physics.
The low light low brightness pictures are indeed not normal, indeed should be exchanged for another device!

also, on the first photo I can see black bar near punch hole
exactly the same as on mine.. will probably send it back
Just got new phone July batch , first impressions are a lot less green tint ..... thank god June panel was a joke July panel I think its still there just a lot less this time ... will see later this evening and post picture back.
black bar across top i can see but not to bothered about this in all honesty.
Colours have to admit whites are cleaner as a result but rest look to be calibrated identical to last panel.
I think my first panel dated May was the best colours just seemed to wow instantly , everyone who saw phone commented on display in a positive manner.
** dupe post del
Here, this is how mine looks like at min brightness: green tint and horizontal bar
Sending it back

Seems to be some QC issues, I'd suggest getting a replacement, I can't see any of these issues on my device personally

Might that be because your device is prior to May on build?
I think it’s pointless replacing now I’ve had three models and it seems inherent now from my own experiences.
Do you use dark mode?
Sorry for the questions just trying to get some feedback
I’m only speculating but my latest device also has it my only device which didn’t have it was built in May , I’m wondering if the early batches had good panels for reviews etc and they cheaped out after that to bring production costs down (speculation as I say) but seen this before with other companies.
One thing I’ve noticed on my latest device is it goes a lot brighter than my previous June model. I’m thinking if I want to keep this device, I’m going to have use light mode which is a shame, if we had root we could just black out all the grey parts like status bar notifications etc and mask issue.

not sure about your theory abt early batches; my device's QC date is April 22 and yet I have display issues
seems this type of issues are pretty common with this panel which is used by both Oppo and OnePlus

well that shoots that theory down
I dont think there`s much point swapping its like looking for a unicorn either return and try a device without this samsung panel or find a way to live with it sadly :/

yep, seems so.. a lottery
the thing is that I can see this issue only at very low brightness, somewhere below ~15%
and in everyday use the display is perfect (I anyway always use light theme)
but then again it bothers me knowing it is there
on the fence now:
send the Oppo back (already have return label) and try luck again with OP8 Pro (order placed, should be dispatched tomorrow; I sent back my first OP 8 for a refund due to same display issues)
or just live with it, keep Oppo and cancel OP 8 order...

Hold onto oppo await OnePlus if it's green then decide on which phone to keep or return both ... Less swaps
Good luck ?
How do you see your QC date?

I cancelled OP8 order that day as I thought that I can live with Oppo's screen. But I can't, so I sent it back today.
Ordered OP8 pro again, it is arriving tomorrow. Will update once received, fingers crossed.
