Hello
I was thinking about buying this phone but i'm pretty sensitive to flickering screens (using PWM control backlight), it gives me headaches that's why I only use flicker-free phones like the Asus Zenphone 2 that has an IPS screen without PWM. I was wondering if it could be the same with this Le Max 2, but even with its IPS panel someone talked about PWM in another thread (https://forum.xda-developers.com/le...ng-problem-t3431637/post72794267#post72794267) so I need someone to check that precisely. There's no information on the internet about PWM on this phone , so I can only ask someone who has the phone to test it for me, and i'm sure it could be really useful for a lot of people that are sensitive to PWM.
To test if the phone is using PWM, follow the instructions :
1. Put a white background on the Le Max 2
2. Put it at 100% luminosity
3. Record the screen of the Le Max 2 with another camera
4. Keep recording while decreasing the luminosity of the phone(20% by 20%) until reaching 0
5. Check if there were any kind of flickering (black lines moving on the screen)
(6. Upload the video so we can all check if needed)
Would be really nice if someone could help !
Thanks :good::fingers-crossed:

I'm sensitive too and can't understand how can Galaxy's OLED have such a visible flicker from PWM and still be considered high quality. I dislike DLP projectors for the same reasons. Never had an issue with this phone though. The user complaint you mentioned was likely a faulty backlight. IIRC there were some reports of two different suppliers used for displays though.

Hi, thanks for your fast reply !
Ikr , that's why I avoid every OLED panel now. Did you do the test though ? It's great to have a feedback but a real test would comfort me way more, especially in low luminosity conditions (this is where PWM is really visible).

I did test in low luminosity. At least with Nougat based ROM (Slim) that I use I can't detect any backlight flicker, even if I move an object in front of the screen in a dark room. There must be PWM* but the frequency is just very high.
*the amount of backlight bleed when showing pure black screen changes as brightness is adjusted
Alright thanks a lot ! Hope this help some other sensitive users too !
TL;DR : After getting the phone and tested it myself, I can conclude that the PWM is not visible on this phone, thus it should be safe for people suffering from migraines caused by PWM flickering.

Hey,
I used the phone for 2 years, and I have been doing fine with it, there is no visible PWM on the Leeco Le Max 2 so if you are suffering from migraines it should not be because of the phone (flickering wise). Now, maybe you're affected by blue light, in which case I suggest you to install the application "Twilight" on your phone and set it up to have a color temperature of around 2400K.

I bought this phone 2 days ago, new, sealed, free from contract, and so far I love everything about it, except for this problem which I have found only today. I guess It was all the first excitement keeping me to notice earlier.
Like the thread's title says, it's like a perfect pattern across the screen, from edge to edge, consisting in perfect parallel 10-degrees-from-horizontal-oblique stripes. They are very very subtle and only visible on light backgrounds and more from looking from the upper part of the screen down.
Do not confuse them with the pixels matrix, whose density, by the way, is great. They are all right, and the effect described above seems to appear on a layer which is on top of those pixels.
To make an almost perfect comparison, this effect looks almost like the striped background from market.android.com (as seen on a computer), but with more subtle greish on white stripes inclined from right to left, and only like 10 degrees oblique from the horizontal. That is what's making me curious, why is that pattern oblique? If it were straight horizontals or verticals I would have confused them with the pixels arrays, and it would have been bearable. But like they are I can't stop but notice this pattern every time and it annoys me a lot! In GMail, Browser etc... all the apps with plain backgrounds...
It wouldn't appear on any close picture I tried to take, and I guess filming for you to see it isn't a good idea either, because you won't notice it. It's only visible with the naked eye, at a distance closer than 30 cm from the screen. It isn't also a problem of my eyes, because my wife is noticing it too.
Thank for any shared thought.

Much better to send you're mobile to the store were you bought it. because as what i have know the problem is the LCD. that is what they called wire stripe or ribbon.... maybe that is the problem. Try it, there is noting to lose.....
I see that too, only on light (white) backgrounds. I thinks it's normal, you may ask your local Sony Ericsson customer service or a phone shop, but I don't think this is a production fault.
On a dark blackground it is purely invisible.
Try it with and without the Bravia engine enabled.

sdk16420, thanks for sharing this, It is somehow a relief for me to know I'm not alone in this. Yet, I'll wait until next week to see if I can find more explanations, and then maybe I'll return it for a replace. It's especially bad for me, as I waited a lot to receive the silver one (a week or so), and I don't know if I can find another.

It doesn't depend on Bravia Engine, unfortunately. It was also the first thing that came into my mind, tried it several times, even with deactivating and rebooting, but the effect is persistent.
Again, it's only visible on light backgrounds, especially white and large ones (browser, gmail, etc). If you read this, please check yours also find some time to post a reply with the result. I would be very grateful.
Thanks!
I have the blue model but i can barely see that pattern with a screen flashlight (on full white) and i don't find it annoying at all in daily use of the phone.
You can check the screen from a new phone in a shop, to see if it looks like yours ... or you have a eagle eye
PS
check softpedia also
I think I can see what you're talking about on my Red Neo but only if I max the screen brightness and look really closesly (like practically inserting the Neo into my eye). 99.99% of the time I don't notice a thing.
I just followed your description and found the same with my neo, so I think it the LCD design. Not an issue to me indeed.
Does anyone have another phone model (e.g. Samsung, HTC) with a LCD touchscreen? Is it also visible on other phones?

I have a Samsung Galaxy S with SAMOLED, a HTC Desire with S-LCD and an Asus Transformer with IPS LCD, and they all have better screens. The Desire's is the most problem free, whereas the Galaxy S has problems with screen burn-in (or image retention, like some are identifying it, but for me it's still like the old good plasma screen burn-in ), and the Transformer's has light bleeding. But, like I said, when put aside, the Neo's looks the worst.
I don't know if you noticed it already, but it comes with another "feature" that is so annoying: it stays always on auto brightness regardless of the custom level set, maxing that automation on that custom level. It's so annoying, cause it's always too dark for me, and being a "feature" it doesn't have also a switch for that. At least it has for Bravia....

When I put brightness on 100%, and hold my finger on the light sensor, I don't see the screen getting darker. What does annoy me is that you can't make the brightness less than about 30%. I use widgetsoid for brightness adjustment, and the screen will only become darker than 30% if I hold my finger on top of the sensor. That sucks. I I want to sacve energy, I have to hold my hand there, while using the phone.
I don't see why people need the brightness that high anyways, aside from in some games with small hard to see details I'm perfectly fine with my brightness set at just 30% or even just 20%...heck I can still use the phone when the brightness is completely off though that does get a little hard to see everything.

I use it a lot outside, and its sunlight legibility isn't as good as SAMOLEDs or others, but that I knew from reviews before the buy. If it wasn't for the problem in this thread, I wouldn't be so harsh on it.
LE I se new posters here. Do you noticed the problem described in the first post? Does it bother you?
Hi all, How are you?
I have a Nexus 9 wifi 32GB "volantis" running stock Android 5.0.1 (LRX22C).
Its display shows a white border/blurry around the device edge on black screens ( or when there is a black area close to the device display edges ), Is this behavior normal?
I appreciate any hlp you can give me,
Roger
Welcome.... Just search for light bleed and you got enough to read ?

Hi mrorange2108,
Thanks a lot for helping.
It looks like that It is indeed backlight bleeding
My screen looks like this one:
http://forums.androidcentral.com/google-nexus-9-tablet/457830-example-light-bleed-nexus-9-a.html
Please, Is there any work around for this issue?
I have read lots of users reports saying that they had requested for a RMA, and They received another Nexus 9 with the same issue.
So, It looks like that It is useless to request a new one, as It will probably have the same problem.
I appreciate any help you can give me,

It's a flaw in the manufacturing process. Basically a hardware flaw, so you cannot fix it, only HTC can replace the parts or replace the whole device. If it really bothers you I suggest using low brightness, since the bleed will appear worse as you increase it.
Also the problem isn't universal. Mine has little bleed, and others can have even cleaner screens depending on their revision code.

If it is something related to IPS screens, thus It does not help to request a RMA, as the new device is going to present the same issue , right ?
It looks like that all Nexus 9 are affected with this problem because It relies on IPS screens, some of them with major degree of screen bleeding, and others less affected - but still with bleeding issue.

You will most likely get another N9 with this issue, but maybe you could get lucky and find one with minimal bleeding if you're okay with RMA. The screen in the N9 might have poor quality control just like some models have bad buttons+pushy rear covers+uneven volume rocker.
And I think it's safe to associate bleeding with IPS & (low quality) TN tech just like OLED tends to show the mura effect.
If you don't want to play the game of getting lucky I suggest waiting for the Galaxy Tab S2, next Nexus, or even getting an iPad if you already use their ecosystem.

Hi Ace42, thanks for helping again.
I understood that all IPS screens have bleeding screen issue, right?
Does bleeding screen issue indicates some kind of another future screen issue?
For instance, If my device has bleeding screen issue, Its screen is going to fail after 3 moths of use?
or Other problem might rise if my device has bleeding screen issue?
I appreciate any help you can give,

No, it doesn't indicate other issues. Light bleeding has been around forever & even TVs + monitors can still experience it to different degrees. I wouldn't worry too much about it because of its commonness. I'm not saying screens can't randomly fall, but if it develops dead zone, yellowing, etc it will not be due to the light bleed.
HTC just has poor QC, it's the job of their employees to evaluate the performance of parts. Despite being an expensive device the quality isn't equal to Apple's.

Contrary to all the crap you will read about "light bleed", it is neither a defect, nor a flaw. It is a CHARACTERISTIC of ALL backlit LCD displays. The reason is has recently become a "defect" in some people's minds, is that there are some display technologies now that do not use a backlight at all, such as the common AMOLED... which has its own set of flaws, such as requiring a much greater resolution in order to yield a similar "look" as a backlit LCD (the higher number of pixels means that you need a stronger GPU), and being extremely poor at accurately reproducing colors.... BUT, no backlight = no light AT ALL from areas that aren't displaying pixels.
Hi all,
thanks a lot for helping.
I understood that black light bleed is a issue in all IPS screens, so if I request a new nexus 9 with HTC's RMA, thus it is going to have the same issue.
Lesion learned: I am going to avoid IPS screens for my next devices.
Thanks a lot,

IPS still a good technology, that's why LG banks on it unlike Sammy. The bleeding can be unnoticeable or severe. That's why quality control is so important.

Hey guys. So I've pre-ordered the Emerald Green version of the phone due to ship on 13 Nov, but I'm still in the process of deciding whether this is the phone for me . It'd be really helpful if those with the phone could take a minute to answer a few questions. Thanks in advance!
1) The GSMArena review just published mentions some minor screen bleed occurring. This is something that LCD screens are more prone to, so I was surprised to hear that it's present on the Mate 20 Pro's OLED panel. Is this something you've noticed and if so how bad is it?
2) I've never used a curved display before and am wondering what the experience is like when watching full screen video (because I watch a lot of video on my phone)? I know the screen in general is considered to be very good, but what about the curved aspect? Is it causing a lot of distortion? Is there distracting glare on the sides of the phone? And what about the unusual aspect ratio - any problems with that?
3) How good would you say the camera is when used simply as a standard point and shoot camera? Is it a camera you need to tinker a lot with or strong under automatic settings?

1) this sort of problem wouldn't be because of the phone itself. Any number of problem can arise with an oled screen on any phone. I don't have any screen bleed at all. They probably just have a slight uneven shift on there unit
2) I'm with you. Never liked curved but I have not noticed any glare. There is a slight colour shift on the edges ..but believe me you don't notice at all in normal use only if you were to stare at the curve intently. The screen is amazing quality .
3) it's early but the camera looks excellent. The wide angle and 5x zoom produces awesome results
I sent back an Mate 20 Pro because (with LG screen) I had intermittent data disconnection issues. I had no gluegate screen issues, the screen was fine. The replacement device has a BOE screen. In comparison to the LG screen, after a few days here are my observations:
- The screen has a greenish tint (not gluegate) when viewed from the side. View the screen at about 45 degree angle (left, right, top, bottom etc.) and the color changes.
- Brightness: the BOE screen I have seems less bright than the LG one.
- The screen also seems less sharp than the previous LG, I would describe it as a bit "grainy" or "noisy", not the pin sharp display you would expect at this resolution
- Low brightness: when the brightness slider is low (10% brightness or less), the grey text breaks up on a black background when scrolling. Here is how to reproduce the issue.
1. Go to Settings and select the BLACK background mode. All text is white or grey and the background is black.
2. Set the brightness slider to minimum
3. Select a submenu in settings (e.g. Battery) then go to a dark room (with brightness at minimum)
4. Scroll slowly up and down the screen in the Battery (or some other) settings menu
5. On my screen the light (white and grey) text breaks up into green/magenta components. When the scrolling stops the text is white again. It's like the screen can not keep up with the scrolling, can not refresh the pixels fast enough so the white text breaks up into various colours.
Anyone has experienced this issue on either an LG or BOE screen? Any feedback is welcome.
I am not pixel peeking. I noticed this behaviour while adjusting some of my settings on the new phone. I did not see this at the LG screen. Because my old phone has been taken back by the courier I can't do any parallel comparisons.
This screen is a BOE screen, serial number 18B08. on the latest 122 software version. Based on my subjective observation the LG screen was brighter and did not notice these low light issues (however I was not looking for it in all fairness). Update: now on 146 software update.
Any feedback is appreciated.
===============================
Update (9 Dec 2018)
I went to a local store and took some comparison pictures / videos between store units and my BOE screen Mate 20 Pro. See them below. All videos taken at MAXIMUM screen brightness on white background to compare the quality (max brightness and colour shift) of both screens.
Here are links to 2 Youtube sample videos:
https://youtu.be/t_BSsJi0f1o - My unit vs a O2 store demo unit
https://www.youtube.com/watch?v=AUPe-z5ArfI - My unit vs a Three store demo unit (verified with LG screen)
Some images also attached.
The green 99% of people report on LG displays is in completely unnatural conditions that would never occur in real life use. They use a grey background, turn the brightness down to 1 and see a tinted glow coming out of the curved part of the OLED display that isn't even part of the actual display area.
The fact that the BOE display is not as bright and smooth as the LG display has been reported by many owners and is also likely the reason there is less light bleed coming out of the curved edges when people use the same unnatural conditions--the BOE screen is natively less bright and powerful at every light level including 1. If you research exactly how AMOLED displays generate color you will understand what I am referring to.
Even though the LG display actually seems to be far superior to the BOE display in normal everyday use with better colors, contrast and pixel response Huawei will probably be using the inferior BOE displays going forward because of the hysteria of some users that believed the LG display was defective.
As far as I know the curved OLED display was used on the iPhone X but not on any Android phone before the Mate 20 Pro so doing the same unnatural display test with the curved Amoled on the Mate 20 Pro and the non-curved Amoled of any other Android phone is obviously not going to yield the same results. The light bleed only manifests where the curve in the Amoled is.
Huawei said this was normal but some people loudly insisted that it wasn't so now going forward everybody is going to get the markedly inferior BOE display.
AMOLED displays do degrade over time so it would be interesting to compare how the LG and BOE displays each hold up but since people are only interested in the newest phones that comparison probably won't happen.
Wow dude, you don't know what you are talking about...
The green is totally defective and can be seen in many normal conditions!
The fact that it's emphasized by grey screen doesn't mean it cannot be seen.
I now have a BOE screen and cannot be happier, colors look excellent compared with my Galaxy S9+
LG green screen was crap. And I'm not biased towards LG, I have a very nice OLED 4K tv at home.

Huawei said this was normal but some people loudly insisted that it wasn't so now going forward everybody is going to get the markedly inferior BOE display.
AMOLED displays do degrade over time so it would be interesting to compare how the LG and BOE displays each hold up but since people are only interested in the newest phones that comparison probably won't happen.

Hello,
Thank you for the elaborate answer.
I don't have a problem with the unevenness of light or bleeding but lower brightness and grainier screen are not OK in my opinion. When I first opened up the first unit with the LG screen, it struck me how better it was than my SONY Xperia XZ Premium's screen, both in terms of perceived sharpness and luminosity. As a first impression.
The BOE screen however, shows much grayer and overall of inferior quality in comparison to the Sony. Might have an inferior screen on this Mate 20 Pro, I don't know, that's why I was asking for feedback.
For this price and being a flagship device having only an "acceptable" quality screen is not acceptable. Having so many posts online and cases of green screens it's a good possibility that there is something ongoing with these screens.

The green 99% of people report on LG displays is in completely unnatural conditions that would never occur in real life use. They use a grey background, turn the brightness down to 1 and see a tinted glow coming out of the curved part of the OLED display that isn't even part of the actual display area.
The fact that the BOE display is not as bright and smooth as the LG display has been reported by many owners and is also likely the reason there is less light bleed coming out of the curved edges when people use the same unnatural conditions--the BOE screen is natively less bright and powerful at every light level including 1. If you research exactly how AMOLED displays generate color you will understand what I am referring to.
Even though the LG display actually seems to be far superior to the BOE display in normal everyday use with better colors, contrast and pixel response Huawei will probably be using the inferior BOE displays going forward because of the hysteria of some users that believed the LG display was defective.

Funny, I was sitting in a dark room with the screen set to grey and on the lowest setting and I was thinking, what the **** am I doing??? When would actually be doing this?? Probably never. I think some people are looking so hard for something that they are starting to see things.
I'm not doubting the there probably are some faulty screens out there, I had one right at the start too. But I've had an LG screen for a while now and it kinda looks green round the edges in that unnatural way of grey screen and low light. But I find it 10 time better than the grey washed out screen of the BOE. I had to turn the BOE screen brightness right up if I wanted to read in bed and the auto brightness was unresponsive.
Normal everyday use of the LG screen is 10 time better and the colours are just more vivid. I think I'm going to stick with LG
I found myself on Spotify with a really distracting green uneven smear all over my screen.... That wasn't a unnatural situation.

biggest pile of rubbish ive ever read in the nicest way possible. to dismiss other peoples experiences just because you havent seen it is rubbish. my friend used my phone in the car at night ( i was using it for sat nav, is that normal enough?) they went on the spotify app to change the song then asked me why is the bottom half of my screen green. if thats not an unusual use case then no one can use their phones at night?

I sent back an Mate 20 Pro because (with LG screen) I had intermittent data disconnection issues. I had no gluegate screen issues, the screen was fine. The replacement device has a BOE screen. In comparison to the LG screen, after a day here are my observations:
- The screen has a greenish tint (not gluegate) when viewed from the side. View the screen at about 45 degree angle (left, right, top, bottom etc.) and the color changes.
- Brightness: the BOE screen I have seems less bright than the LG one.
- The screen also seems less sharp than the previous LG, I would describe it as a bit "grainy" or "noisy", not the pin sharp display you would expect at this resolution
- Low brightness: when the brightness slider is low (10% brightness or less), the grey text breaks up on a black background when scrolling. Here is how to reproduce the issue.
1. Go to Settings and select the BLACK background mode. All text is white or grey and the background is black.
2. Set the brightness slider to minimum
3. Select a submenu in settings (e.g. Battery) then go to a dark room (with brightness at minimum)
4. Scroll slowly up and down the screen in the Battery (or some other) settings menu
5. On my screen the light (white and grey) text breaks up into green/magenta components. When the scrolling stops the text is white again. It's like the screen can not keep up with the scrolling, can not refresh the pixels fast enough so the white text breaks up into various colours.
Anyone has experienced this issue on either an LG or BOE screen? Any feedback is welcome.
I am not pixel peeking. I noticed this behaviour while adjusting some of my settings on the new phone. I did not see this at the LG screen. Because my old phone has been taken back by the courier I can't do any parallel comparisons.
This screen is a BOE screen, serial number 18B08. on the latest 122 software version. Based on my subjective observation the LG screen was brighter and did not notice these low light issues (however I was not looking for it in all fairness).
Any feedback is appreciated.

inn regards to this. the BOE screen seems to be less vivid if you had the LG phone before. however i had my S8 on standard or SRGB mode. (maybe it was called basic i cant remember) and to me the colours look fine. i cant say it looks less 'smooth' not sure what that means either and i think you hit the nail on the head. when you start to pixel peep youll see many flaws. even if they arent really there. if you look at the LG display as hard as you have looked at teh BOE, maybe you would have found something else. I know the whole display thing is annoying for the price but i took into account selling my s8 and selling the WAtch GT (which i am using at starting to like) into the price
I think low brightness usage of a screen is a valid scenario which should work properly without green issues. I am occasionally reading ebooks in the dark, at minimum or close to minimum brightness. I had a number of smart phones and they all worked fine with a pretty uniform screen. I am not looking for perfection, but low light performance is a valid usage scenario where smartphone screen have to deliver - especially top tier, expensive flagship models.
I have the LG screen and apart from the greenish tint on the curved sides when viewed in a dark room with grey background (low brightness), I really have no issues during the day when there is normal lighting. I've read several forums with other phone manufactures where this complaint seems to be common, clearly Huawei could have done better QC. For me at least this nuisance isn't enough to return the phone.
Hi The LG is very bad, did you see the anandtech review of the Mate 20 Pro

That makes sense. For me the overall brightness and sharpness is important as I am doing a lot of work outside surveying buildings. This is what I am apparently seeing in my BOE screen, the screen seems to be greyer and less bright than the LG one. But again, it might be an issue with my screen only - that's why I am looking for others' feedback.

Thanks for sharing this review - it's so comprehensive and technical, without being too technical (if that makes sense).
On my 3rd phone with this being first BOE screen.
1st LG screen was utter crap, by the 2nd week at 50% brightness you could see the green around the edges on youtube videos etc... ( I would count that as most peoples use of a phone?)
2nd was much better but was still noticeable while using dark theme and dark backgrounds, which I do a lot. Main issue was I didn't want to wait for it to get worse like the first one.
3rd BOE - Much better screen. It is slightly less vivid but still plenty nice enough for me. Sharpness I have it set to FHD all the time and haven't noticed any issues at all. Only thing I did notice is there is a slight green tint viewed at certain angle, but pretty extreme angle which is unrealistic so doesn't bother me.
I don't think this is an issue that's specific to LG or BOE screens because I had this on my 2nd LG device. I thought it was because I was using YouTube vanced but obviously not. These screens are garbage.
I think OLED screens all have the problem to a certain degree. Just some are worse than others.

Sorry but you are dead wrong. This does not remain this way. The LG panel shows the green after a few days even on 50% brightness.
The BOE screen is exactly as bright, clear and sharp as the LG and I know this because I had them side by side.
Don't spread nonsense. LG screen TEN TIMES BETTER? Shame on you.
For your information, Huawei admitted to EE on the phone that all the LG panels were in an early batch, and faulty. Good luck getting help when your LG panel goes bad, and it will.

No need to take that tone. We're all adults here so please don't act like we're back at school. So shame on you!!
It was just my opinion. I have both of them next to each other and there is a difference, I even posted pictures on another thread showing the difference in colour. I'm also not the only person to notice. Plus I've had my LG screen for 3 weeks now and it hasn't got any worse.
I mean jeez all these people getting het up, when it comes down to it, its just a phone.
I have a BOE screen as a replacement for my (slightly) faulty LG screen.
I've had other LG & Samsung OLED (both P-OLED and AM-OLED) screens on phones as well as many LCD screens.
I can honestly say that the BOE screen I now have is at least as bright as *ANY* other OLED screen I've had and pretty much as bright as the SuperBright LCD on my LG G7 Thinq.
The resolution of the BOE screen is also pretty bloody good; certainly no worse than it was on my LG screen'd original Mate 20 Pro.
I don't see any light bleed; only the "usual" colour shift evident on pretty much any OLED screen when viewed at an angle; and for me this phone hardware-wise is now pretty much perfect.

I'm sorry but you made so many mistakes in your assertion. First the LG Display is by no means superior. The BOE display uses the new Synaptics driver that is light years ahead of the Unkown LG driver. I have meanwhile in my family the possibility to test the LG Display directly with my BOE display. The only thing I mentioned was that the colors were a little more vibrant on the LG. After adjusting some parameters my BOE display looked almost identical to the LG. But without the green tint. And your claim the green tint is not that visible under normal circumstances is totally rubbish. On my first mate 20 pro the green was visible under all circumstances. Not from the start, the issue progressed. I must admit Huawei handled my issue very good. I got from the start a very good BOE panel. And believe me if the green tint was anything normal, Huawei would never have exchanged the devices that easy.
My BOE Screen is great, clear, sharp nice and bright. Except for when the Power Genius app kicks in for Gmail, Chrome and Facebook.
So, I have been seeing many reviewers commenting potential display quality issues, mainly screen bleeding all the way around the screen and punch hole.
I know it can be considered as normal for IPS LCD screens, but many say it's really noticeable and can be annoying. Also, pretty low brightness is reported as under-average.
It seems, according to what I have seen and read, that display is downgrade from Redmi Note 8 Pro, which has pretty good display, no screen bleeding and decent brightness.
So, those who have Note 9 Pro (9S), have you experienced this issues, is it a general thing, or maybe it's just some batch in question.
I really would like to buy a phone, but I wont take a bellow average display as compromise.

Not confirmed from my side,no visible bleed around the camera hole. I was asking myself about this reported claim.
Display is good for me and can easily compete with my old MI9T.
I don't regret buying this phone.
I was hoping to hear that, because I've also saw people commenting that their units are free of any kind of screen issues.
But it seems some batch of phones is impacted by this issue.

Mine is perfect. Don't listen to Frankie from Frankie Tech on YouTube. He's full of $hit.
Mine is fine. Nothing noticeable. ??
Mine is two weeks old and absolutely fine. I have yet to notice light bleed (should I have, or would I need to look for it?) and there's no display retention issues.
I notice the faded color around the screen, im thinking on a return. But dont know if its normal, cause cant notice on some apps even at max brightness. Just got the phone on Sunday
