[Help] Image retention problem in Redmi note 4 - Xiaomi Redmi Note 4 Questions & Answers

Hi there. I own a redmi note 4 and I've been using it for a month now. Last week I noticed some odd icons on a plain grey wallpaper and realised that the display has an image retention problem. I could notice Facebook icons as well as whatsapp ones that I had used just a minute before. Any app I use immediately leaves a residue in the background, even at low brightness. I immediately went to the nearest MI service centre and replaced the LCD panel under warranty but after getting home and taking a closer look, I realised the problem still persists. Any help regarding this would be highly appreciated.

There is no fix. Generally the retention goes away after a few minutes-hours.

Yes, it does go away after a while, but is this normal across all redmi note 4 devices/ devices with IPS LCD display? One of my friends has the same device and he hasn't noticed anything like this so far..

I had it on my mtk redmi note 4. Now im using snapdragon rn4 havent noticed it tough but i dont stick to one app for a long time though

I found fix run this app for 30-1hr then cooldown your phone
https://play.google.com/store/apps/details?id=com.blasterbyte.burn_infix
And use this app to prevent screen burn
Bluelight filter - search on playstore
See mine after i run this app my burn is gone

is the solution permanent? does the problem happen again?

Found Fix
I found the solution.. Just flash havoc rom will fk kernal.. Use smart pixel feature. Set the smart pixel setting to 25 percentage... And in display setting go to colour and set all the value to 95 percentage.. Done ??

Stuck pixel

I notice there are stuck pixels on my reno 4,is that normal?do you have stuck pixel ?and anybody knows how to fix it?
i have notice but i see them only when booting my phone there are many .. But i dont see them when phone is booted everything is perfect so i dont think its problem
I think there is a percentage basis depending on the manufacturer but If you have anymore than 3 dead pixels I would be looking to have the panel replaced under warranty.

not really stucked pixels, you should try with maximum brightness, black screen to see when you phone boots up completely.

How about yours?
it happened to me lol. The MI bootlogo got stuck for 1 minute. It was like an amoled burn in but after that it went away.
HOW IT HAPPENED: I was installing a ROM and it took some time to boot at the MI logo (3 minit) and the MI logo got burned on the screen. After that I used the phone as usual and the burn in MI logo disappeared. I cant guarantee my problem is the same as yours tho.
When I bought my phone I checked it for like 5 minutes in the store to make sure that I don't have any dead/stuck pixels and only after I verified that I bought it.
Anyway I think they won't cover it under warranty unless it's more than 3 pixels but you should try anyway.
And by the way burn-in and stuck pixels are different and since this is an LCD display the burn in will go away after a few minutes but a stuck pixel can stay forever even if it's not a dead pixel.
It's a known problem with the Redmi Note 4. The panels are bad \ low quality.
A shame really, great phone other than that.
It seems the number of stuck pixels is increasing with time. I also didn't have even one stuck pixel when I got it, and I have around 20 after 1 month of use.
Yep. Have stuck pixel. When I got it, I checked it and did not have any. Over time two appeared. Since it's a low budget phone and low quality , i think it's normal. I usually buy a phone with quad hd screen to bypass this problem. Cause with quad screens, the dpi is so high that you won't noticed any dead or stuck ones. But oh well, you get what you pay for.
Has anyone replaced screen panel and fixed the problem?
bump, looking for a solution to this.
i got that too :crying:
because mido have 2 type lcd
i forgot the name
1 type is have a good quality
and 1 type have a normal quality

Manufacturing Defect?

Just got the new Redmi Note 4 (64GB+4GB) yesterday and spent half my day setting up the phone and transferring all of data to it. Some time late in the night I did a reboot and while the phone booted in the first boot screen that is, a completely black screen with Mi logo on it, I noticed a few coloured spots ranging from the bottom of the screen to the top. Once it booted up, I went into the gallery and opened up a completely black wallpaper, turned on the brightness to full and zoomed in the black portion of the wallpaper and again saw those spots at the exact same place.
Is this a manufacturing defect?
Thank you for your help.

Have they gone away? The screen is known to have temporary burn in that goes away after like 5 hours
I also noticed these spots on my screen. Is it a hardware or a software defect? If it's a hardware defect, Xiaomi should address this asap. I can't have a brand new phone with burnt dots on screen.

Just checked again and there are still some spots. Majority of them seem to have gone away. Will check again in a day or so.
I don't have any spots on my screen at all.

Have you flashed any Roms since you got it? Could you be running a buggy vendor/reseller ROM?

Haven't flashed anything yet. Got the phone yesterday. Contacted Xiaomi service centre, waiting for their response
dead pixels. xiaomi phones have always had dead pixels at least in all the phones i have used. redmi note 4g, note 3, mi4, the 2 replacements for redmi note 4g all had 5 or 6 dead pixels. sometimes they are not visible until you forcefully try to look for them. 1 or 2 dead pixel is fine and i used to freak out earlier but now i have accepted 1 or 2 dead pixels whenever i buy a cheap phone. only my mi pad had no dead pixel. almost all brands have 1 or 2 dead pixel and that can be ignored but more than 5-6 can't be ignored imo.

Stuck pixels spotted
Hi
Even i have more than 30 stuck pixels,
some are small and 4 pixels are big among them and they are Cyan blue colored.
Same problem here. But my wife's phone doesn't have it. Same model
Please raise a complaint to Xiaomi and get it replaced at the earliest. Sounds like dead pixel issue.

Dead Pixels on the screen

So after month of owning this phone (SD version), yesterday I noticed that there was green pixel on dark backround. After a while of looking at black picture with max brightness, I noticed several small red-blue-green dots all over the screen, which weren't visible on other backrounds. I have already sent it to repair centre (free screen replacement). I just wanted to ask, is it frequent problem with RN3 or I was just unlucky? Is there any side effects of replacing the screen?
I'm using this device for about 6 months now and i haven't seen even one dead pixel in my phone till now, but I haven't noticed even one dead pixel on the screen till now...
So, I guess you were unlucky and your device had this problem...

Can you check it on dark room, with dark backround and 100% brightness? Just want to make sure Also, I think I was unlucky too, I hope replacement screen is better.

I have rn3 sd version.
and I noticed 3-4 dead pixels on the screen
it cannot be seen on regular usage. hardly can be noticed when lcd test (dark screen full brightness)
I think many rn3 phones have same problem. many users just have not noticed yet.
it's common and expected, for the price you won't get the best panel, i also have 2 stuck pixels, one green and one red
Yeah I got one too and maybe 2-3 more...but not visible in normal usage.
Happened after like 5-6 months.
hmm, it seems that many are having stuck pixels, mine just had too many and it's free screen replacement anyway, so Thanks for replies guys.

I couldn't spot any dead pixel on my phone....
I guess I'm the lucky one then:fingers-crossed:
Some of my friends have the same device and they also don't have any dead pixels...
Well, see if your replacement panel also have the same issue...
Edit: I don't think that's a kernel bug as many users including me are on Radon and none of them reported this issue...
I have a unusual red fingerprint that barely visible on the bottom part of my screen.
You can only see it on still black screens and you will have to look carefully to see it.
It is a comment problem to LCD screen my all phones have dead pixel except Redmi note 3

Yeah, I'm pretty sure thats not kernel related (I haven't flashed any custom kernels anyway). I hope replacement screen will be good.
I had a orizontal green line at bottom only on miui.
On aosp doesnt exist.
My phone has several blue and green patch, when I purchased never noticed it till 1 month. After that I got screen replacement when I visited service center, Now my phone creeks.. If grabbed hard its back panel creeks.
I don't blame, Its a cheap company and cheap phone. But performance is good.

Creaking is actually common on RN3. Althought mine didn't (well, I was using a silicon case) and I don't think screen replacement did that, unless service center did a bad job at it.

Actually back panel is rubber glued. (The speaker and upper panel) I think when they open up phone, for screen, they removed rubber glue, so now it creeks against plastic..

[HELP] Screen leftovers from other apps, (lcd image burn)?

So recently my phone has ghost images, leftovers from other apps on the screen. (eg. The top bar showing up ghostly when it shouldn't, controls of a game showing up on home screen after closing the game in a ghostly effect) It is not a software problem. I know it goes away on its own after some time, but it's very annoying and its freaking me out. Anyone else got this problem? How do I fix/prevent it
i got it to.not know hot to fix it
Very disappointed from xperia screen
I have also the same problem and it looks like a hardware issue. It's very noticeable when you increase the screen brightness. Notification bar icons/time appear all time against any dark background. Very annoying, even cheap phones don't have that problem.
Example I found online -> lnv.i.lithium.com/t5/image/serverpage/image-id/79782iF19656F933D1C741

Yes, thats exactly my problem. I noticed that it gets worse if the device is overheating
Sorry for the bump, but is any else having the same issue?
Mine seems to be getting worse and worse over time, to a point that it can literally retain half way up the display.
I use to have the same issue with my iPad Mini Retina until I took it in for a replacement and it hasn't happened since (2 years ago).
Any experiences with Sony replacing the display under warranty?
Thanks,

Wow, yours got on the next level. Mine isnt so bad. Actually , I rarely have the problem lately. Do you run poison 7.1? That particurar ROM I was using was problematic, causing the phone to overheat and the lcd problem was present all the time
Mine is completely stock and unrooted.

running completely stock & unrooted. Mine has this problem too. However, the image disappear after 10-20 minutes :|
I had this problem on my unit as well. Tried to adjust the white balance and it seems the issue was barely noticeable on the status and navigation bars.
The good thing is that screen retention falls under manufacturing defect and you will get a new screen.
Mine got replaced with a brand, spanking new one, but the issue has started to creep in just a little bit after a few months, but its very faint.

screen retention problem?

I'm thinking of buying note 9 pro global (joyeuse), but I've been hearing it has some problems. I don't have problem with software bugs, but some people said it uses Tianma panel which has bleeding and image retention problem.
If it is a gardware bug, it'll cause problems. Can anyone guide.
Thank you

yes its a serious hardware fault, tianma panels have burn in issues + there is a WIFI related hardware issue as well, I made the mistake and bought the phone thinking these won't affect me and now I have to put up with a phone which loses wifi everytime it goes to sleep. SKIP THIS PHONE IF YOU CAN.

Mine doesn't have that issue. Did you try test with a different router? I have no screen issues other than slight bleed from the hole punch which is barely noticeable unless you look from a side angle on white background. I love this phone and have no complaints.

I don't know which version you have but all Global note 9s and indian note 9 pros have the wifi issue, numerous threads @ Mi community and even on xda there is a thread with many pages. About the screen issue just google "Xiaomi note 9s screen burn in" you will see many videos about this.
Most people who are saying they don't have the problem may not be checking their router logs, because the issue is hard to notice on 11.0.8 and above firmwares, the phone disconnects from the wifi but reconnects automatically after a few seconds so the end user does not know whats going on ..... unless he checks the router logs or uses whatsapp web with this phone, whatsapp web will actually disconnect from the phone after its wifi 'disconnects' during standby...it may take 10 minutes or 40 or an hour but it happens its a well documented issue even the Mi community Moderator for 9S confirmed this as a "documented wide spread problem" but has not been able to give a confirmation if/when it will be resolved his last response mentioned waiting for MIUI12.

I have the EU version. Look I had similar issue with my previous Note 5 and Note 8 but it was fixed by not using that router. I plugged a cheap router in my main router as access point and never had the issue again. I'm 99% sure it's some routers that don't work well with Redmi phones. And as India had millions of people a lot of them will be using the same routers. That is why I asked if you tested on a different type of router so we can confirm

and do u u have this screen persistance on your panel?
FYI: Tested my joyeuse, manfucatured Aug 2020, with a Tianma display. Using a checkered pattern, full brightness, for up to 20 min. or so. No ghosting/image retnetion whatsoever.
I bought a note 9s with tianma panel with no lightbleed at the edges. There is also no lightbleed at the selfie camera cutout but on a white background I notice a slight area of reduced brightness (not grey but a little bit not as white as the general panel color) at the bottom part of the cutout. It is very small and curves with the cutout shape and I also have to look from an angle to notice it.
If I'm to nitpick, if i put on a white background and set brightness really high, i can notice some areas of slightly less brightness at the left and right bottom extremes extending about 0.2mm from the curved part. These are so far from anything that no app has any content there so it doesn't bother me. I also have to look at it from an offset angle (about 100°). Who uses their phone looking at it from this extreme angle? Like i said, the display issue is nitpicking.
I can't say anything about wifi because I'm mostly on 4G. That's a worse issue than the screen but apparently it could also be eliminated by changing wifi routers.
I bought mine (6+128 GB) for $200 and compared to other phone brands, this is a lot of phone for $200 so I'd recommend it to anyone and everyone. This os my first Xiaomi phone and I'm already a fan.
Sent from my Redmi Note 9S using XDA Labs
I use Redmi Note 9s 6/128 vatiant and it does have screen burn. Whenever i play cod for a couple hours some of the buttons still appear and will appear for a few hours. I also read alot of Manga and the edges of the screen would turn yellowish/orangey on gray shades. Still not fixed and been suffering for months already. It's less visible on white screen but very apparent on gray ones
