Hello guys , i noticed the the infrared led from the proximity sensor is always on, even with the screen turned on. Isn't it supposed to turn on only when you make a call ? or when you use face unlok ( but it's non my case, since i don'e use any lockscreen )
I have an another samsung device, an galaxy s9, and the led turns imediatly off when you pass the lock screen or you end a call.
This is my second Note 9 device, both had the same "problem".
I uploaded o video on yuotube, i cant post the link since is my first post. But you'll find it on youtube " Samsung Note 9 IR led allways on "
Thx
Mines off after face unlock is used...
Took picture with another phone to see if it was on, it wasn't...
Might be something wrong with your Note 9 or an app you are using might be causing this, especially if it's a problem that has migrated across 2 Note 9's...
This is my second Note 9, both with the same issue, and the odd thing is that this morning i chatted with samsung chat assistance, and they claimed that even their test model had the infrared led allways on , and that it's normal to be like than ! In my modest opinion, i think that it'a bug (related maybe to the exynos models ).
I do not know whether to keep the phone or to get a refound.
The infrared LED is on when auto-brightness is enabled to detect light, turning auto-brightness off will turn off the LED

I assume OP is not refering to the infrared flood light used during iris scanning
It's the smaller LED near the proximity sensor, visible with a camera or something that detects infrared-light
Gsam used to always show high proximity sensor usage on both my note 9 and note 8 . I turned off smart alert and usage dropped by 90%.

I'll try to switch off smart alerts to see if the situation improoves. Since now i tested 3 samsung models: s8+ , s9 and mine note 9, all with th same settings , and only mine keeps le infrared led on .
With my first note 9 i tried a factory reset, reflash fw with odin , but with no luck, so i asked the seller to change it with a new one. And even this one has the same " issue" ( if we can call it like that )
I like the phone but knowing that i have a infrared led allways on in my eyes , it's bother me.
By the way i have the exynos version.
Hi quys!
first of all ,sorry for my bad english!
but, i recently bought xiaomi mi 9 , i had lot of problem with it till now but the most important of it, its about display panel.
my perivious phone was samsung s8 Plus and s8 display was awesome (its 2 years before phone) but my mi 9 display not good as s8 plus , not even close, is this normal? or my phone have problem software?
Hi, what problem did you get ?
I had the reglular Samsung S8 and I find the Mi9 panel not far from the S8. As it is 1080 and not 1440 it has not as high pixel density, but I am more than happy with the Mi9. Never have any problems in bright sunlight as I could have with the S8.

thanks for your reply, but i a disappointed the first time i saw mi 9 display. i think the icons are like washed out and not sharp. i saw someone in this forum said after update mi9 , have a better display and compared his phone with S9!
my next problem is updating miui. my mi 9 is china pack and the website that i bought my phone , open phone box and flash global rom on china rom in china country and send them to customers. i have weird problem with the phone.crash app frequently ,google play service crash and stop ...,the worst problem is closing all apps and go to lock screen and after unlocking phone ,the message "find device closed unexpectedly" showed me and if im not reboot my phone this problem repeat and even sometimes my phone reboot itself even twice or more. now i signed out from my mi account and i turned off sync option and set off battery optimization and lots of setting option, and betternet app (vpn) not use anymore (this app made a lot of problem for me , i think) and now i have a better experience. i wished a new update fix my all problem . i am on V10.2.9.0.PFAMIXM Global Rom and new OTA Update V10.2.13.0 shown on my phone after downloading update , my phone reboot to start the update but after 25% in fastboot update failed and not update this time OTA Update is 2.2GB . i repeat this process a lot and no progress. even downloading zip file by PC and update manually not help, phone it said this is not official update.
what is the problem of my phone for OTA Update!?
You might be looking for more vivid colors. Go to Settings, Display, Contrast & Colors, and see if moving between "increased contrast" and "Standard" gives you more of what you expect to see. You can also set the color temperature to better match what Samsung uses by default

Yes, didn't think of that as I always tune down the overly saturated Samsung displays!
The auto brightness also seems to be a bit off. I have my brightness forced.
If you have DC dimming turned on, it can also change colors if you are on a lower brightness.
Coming from note 8 i am very satisfied with the screen, if the note is a 10" the mi 9 is 9,5". (i change the settings to be more vivid). I

Okay, now that I got your attention, this is a SERIOUS issue. You may not even realise it, but if you’re not using MIUI, you pretty much have a Screen Burn In / Image Retention problem on your RN 8’s display. It’s temporary though, and goes away after a while. You can see for yourself, but I’ll come to that, and also to why it doesn’t really happen in MIUI. Also, the RN 8 isn’t the only device affected!
The issue:
This never happened over the 5 months I’ve used MIUI. It’s been a month since I flashed Pixel Experience Q, and I’ve noticed when opening Reddit, in its dark grey splash screen, I could see my notification bar and some app’s hamburger menu faintly. It started bothering me, and I started researching. How can I get burn in on a new device!? And heck, it’s an LCD. Turns out I’m not the only one. A quick Google search on “Redmi Note 8 Screen Burn In” gives you tons on people complaining, even here on XDA. Many think it’s a hardware issue, and replaced their display and still faced it!
See for yourself:
Open this dark grey picture linked below in full screen in your gallery. You may notice the notification bar burnt in. For a better example, exit your gallery with that picture open, set brightness to 100% and screen timeout to 2 mins, light mode, and just open settings and leave it alone. After almost 2 mins, quickly go back to your gallery with the picture open. You’ll see settings lightly imprinted into your screen!
Here’s the dark grey picture:

Here’s how it looks (sorry for the crappy quality!):

Solution:
Turns out that the Tianma LCD display panel found in most Xiaomi devices, like the RN 3, 4, 5, 7, 8, Mi 5 etc have to have a specific colour calibration. You need to set the Red, Green & Blue values to 90% in your ROM’s colour calibration. Take a look at these:

https://forum.xda-developers.com/re...utorial-how-to-fix-screen-burn-issue-t4014519
Here’s how colour calibration should look, I stole this image from somewhere
https://imgur.com/pgTExqo
MIUI already has the right calibration by default.
But here comes the biggest problem for some of us. Pixel Experience Q, the most popular Custom ROM for RN 8, doesn’t have this option. I tried Franko Kernel Manager with the stock Kernel and Genom kernel, and the display RGB values make no effect. So as of now, I’m stuck with this. Any tips? ROM’s like Havoc should have it though. So dev’s, please set this as the default colour calibration value!
I hope this helped, I put 2 hours of effort into it haha.
On another note, I hope y’all are staying safe from this epidemic!
bro i have it in miui .. its hardware not soft .. i noticed it in different xiaomi devices like note 8 - note 7 - and sure poco f1 .. then noticed it in realme 5 pro .. not found in my very old samsung grand prime / though companies nowadays go to those low end panels .. all of them
I have the same issue on MIUI (stock rom) too.
I did the exact same steps you described and I got the burn in. Well it is not much, I could see it only on full brightness though. Not much of an issue for me on such a budget phone tbh.
Changing the color calibration for all colors to 90% might help to reduce this burn-in, speaking of custom roms to include this as a default setting.
But it won't help with this cheap panel, which is ineed a hardware issue anyway.
Setting all 3 colours to 90 % just reduces overall brightness nothing else.
Thank you! Display colors can be changed on crDroid 6.4
https://t.me/InceptionNote8/66967
this works well for me, use franco kernel manager
It is not the rom issue
I'm seeing this issue in stock rom and i never changed roms till now. It is bcoz of poor quality display panel. Get it replaced ASAP before warranty runs out
I dont know if this is universal but setting the colour tone to cool fixes the issue completely in my redmi note 8
just change the color calibration to this and voila, u never experience burn in screen anymore. i changed it couple weeks ago and no burn in AT ALLL untill this day!

I own a MI A1 it's 2 years, 9 months, 2 weeks, 3 days Old and has screen burns in.
not unlocked bootloader.
no twrp,custom roms,rooting.
but being a budget device (having eMMc type of storage) i have no regrets it performs very well against phones of Exynos 9609(UFS2.0), SDM665 (UFS2.1).
Comming to the topic "screen burns" will go away on its own not a matter of Great concern, leave it like that only it will automaticly go away its not Permanent .......... :fingers-crossed:
So suddenly the display of my note 9 suddenly became wierd, where black suddenly displayed yellowish tint, blacks were dark Greys. Already perform factory rest, color adjustments and so fourth. I'm wondering if the following behavior is normal

My Tab S6 does that sometimes, only in setting menus but it's fine when am on YouTube and Browsing the net and use other apps. My Note 9 does not show grey colors when in settings or other menus! Try turning brightness to around 20 to 25% then try ?

Sounds like you might have a faulty display! Ring Samsung and get it replaced! i can see in your 1st pic Brightness is maxed out OLED panels can easily burn in! maybe it's burnt in, that's why your seeing yellowish and brown as the panel is shagged!

Big thanks man, I have being freaking out lately over it
My screen sometimes stays like this.....
Is this software related?
I even try a full format, but sometimes it stays like this, the green cames.
https://photos.app.goo.gl/okhHvVyuBtgy7ZYq5
That's the beginning of the headache if your situation follows mine. I also noticed a weird green hue about a week ago on dark grey background, but thought nothing of it, until the whole display became awashed and green and glitchy in normal brightness like the article above suggests (it still looks sort of acceptable in 10-20% and highest level brightness though). If the March update is to be blamed, I cannot wait for April update because right now there's just no service centre opening.

We all are facing the sams issue. Like the article says its mostly because of software update however after getting this problem some were downgraded to android 9 but no luck. Seems Samsung is willingly glitching their customers after warranty period is completed. We created Telegram group also search in Samsung members you could join there.

Are you sure, that even a downgrade (via Odin) is not fixing the issue ?
Than : Samsung Damaged the Screen with the update !
Iam not hit by the problem.
But maybe soon ? (Exynos here)

Hi, I recently bought a Realme GT 2 8/128GB Global RMX3311_11_A.14 firm and have been using it for past couple of days.
What I have noticed like artifacts around black text on white background, like a bright halo under dark shapes and clear/light background, it's like a 1px brighter-than-the-background, like a broken anti-aliasing/ClearType or maybe is that the sharpness is very high.
I have tried all the configuration options available for the screen but there have been no changes. For example, in the list of Wi-Fi networks, in the password field, if you look at the black line, it is in one of the places where it is most noticeable.
https://imgur.com/t50LOm5
it is very difficult to capture with a camera, this is not my phone but the same thing happens
https://imgur.com/zOkyWWG
I think i have same problem which is reported in this other thread for a Xiaomi phone https://forum.xda-developers.com/t/over-sharpened-mi-11x-amoled-display.4319715/
Is this normal or there's any problem with my display? Is this a Realme UI 3 issue and can be solved in following updates?
I have other three Amoled phones and this DOES NOT happen to any of them! (Realme 8, Oneplus 3T, Xiaomi Mi A3)
thanks!

Do you have DC Dimming enabled ?
I noticed that when it is enabled in low brightness and black background there's some flickering on the page text when scrolling.
But that particular issue I don't have.
Hi apsol, thanks for your answer
No, I did not have DC dimming active, I have tried to activate it but it has no effect on what I comment
with time I'll get used to it, now I know it's there and I see it. What I would like to know is if it is a problem with this AMOLED panel or rom/driver issue which could be adjusted via software
I know how it is, once you see it you can't unseen, it would drive me nuts too. Hehe
Have you tried testing for dead/stuck pixels if it doesn't show there my guess is software.
I'm on RMX3311_11_A.14.
What about you ?
Hi,
Same firmware version here, RMX3311_11_A.14 global
the truth is that I am not sure if it also happened with the A.13 because I almost updated it at the moment, I did not realize this until I was in the A.14 ...
thanks
The same problem on my phone. It is easier to see also on black background with white font.
Unfortunately I think this is a screen issue not soft
Have anyone have similar issue? Is this global problem or only 2 of us struggle with this issue?
Check if you have high contrast text enabled.
I have high contrast disable ( but the same issue is visible when option is on). Do you have this is issue? Or should I send my phone on RMA?
I don't.
If it bothers you that much return it.
Hi again,
After continuing to search for information on this issue, I found following post on reddit that I think has the same problem with an iPhone 13
https://www.reddit.com/r/iphonehelp/comments/tdy5tc
I think it's a common problem with AMOLED screens, but in some it is more noticeable than in others and it also depends on the user
after detecting it on my Realme GT 2, if I make an effort, perhaps I could say that it also happens on my OnePlus 3T, however the difference with my Realme is remarkable, the same with a Realme 8 of a family member
By the way, another thing that I have detected is a color shifting when the viewing angle is varied, much higher than in my other devices with AMOLED, it must be said that the larger the screen, the more noticeable it is
I'm a little disappointed with the screen to be honest
thanks

I came specifically to this forum to check whether its true about the screen's colour shift and font edge issues. Seems its true. Its believed that they have used the same samsung E4 hard screen, that they used in oneplus 9RT. You can check 9RT's display review below:
https://www.gizmochina.com/2021/10/22/oneplus-9rt-review-perfect-balance-camera-price/
There is also a Chinese video on GT2 display. Its a review of k50 and gt neo3, but they have shown display of gt2 also. Watch from 2:30 min.
I don't see that problem on my gt2 in normal use.
I also have the blue shifting even when looking straight. I try to ignore it.
Someone told me it was the screen protector but I never removed it to be sure.
But every review I've seen there is color shifting.
