Question POCO X4 Pro 5G AMOLED screen shows some bright spots on dark/black images.

[HfTFranz]

Hello everyone! I just got my POCO X4 Pro 5G phone yesterday. I absolutely love using it to bits.
However, I noticed that while browsing through content on medium (40 - 50%) brightness, the phone does not actually go fully dark. Some parts are lit up while others are not. (On dark videos and imagery, it is noticeable enough to really bother me even on just my first day of use.)
To elaborate on my point, I have downloaded a completely black picture and displayed it on my phone.

I have attached the photos below.




Setup. (This is the phone displaying a completely black image on my gallery)


Lights off (Captured on my Samsung A50 normal mode)


Lights off (Captured on Night Mode)

I have tried to capture it on video, but it is simply not visible enough on video to be worth your time. You'll simply have to trust that I indeed downloaded a completely black image and displayed it on my gallery. (I wouldn't be posting here for no reason if I was lying, wouldn't I?)



Anyway, it is worth noting that on both higher (60-70%) and lowest (0-10%) brightness, the issue disappears completely (e.g. the screen completely shuts off as expected.) but then some of it return on maximum brightness.

Now I can definitely use the screen all the time on these settings, but I also want to ensure the longevity of my AMOLED screen, and it would suck to always be watching content on effectively only two brightness settings.



I have tried using AMOLED Fixer apps on Google Play but to no avail.

Does anyone else have this issue? Do you think it is fixable through software? Should I return the phone to POCO before it's too late?

Thank you for any responses in advance.

I am not able to reproduce this on my device. I've tried all brightness levels, no weird spots on my end. Maybe you should RMA your device. But let's wait and see if anyone else is having this issue.

Thanks for your input. I did find someone on reddit having a similar problem to mine, on his mi 11 lite. Unfortunately, the solution offered on his replies does not exist on my phone's settings (I can't find P3 anywhere).

This makes me feel like it could be a software issue, and I'm really liking everything else about the phone so far so I'm still thinking twice about going through the return process. But I still have some time to think about it for now. Please let me know if you find a similar problem with a potential solution!

Interesting... I'll be sure to check my phone once it arrives, cheers

It is recommended that you update the system or set up debugging, good luck

Some updates, I guess.

I sent the phone to a local authorized Xiaomi Service Center in my area. While the technician did indeed see and acknowledge my phone's problem (e.g. he did see the screen light up on a dark image), he says it is a probably normal operation for my phone. (Which I personally don't agree with, because again, AMOLED screens must be completely dark.)

They simply updated my phone's software and did not replace the screen, and did remind me that if it did go worse, I still have a 1-year warranty for the phone if it breaks. I really needed to use the phone to travel so I didn't bother bugging them more about it.



HOWEVER, while testing things on my own I did notice some possibly noteworthy observations:

- on the almost near to darkest settings, some colors of black become dark-purple/reddish (particularly when I use Spotify).

- when restarting the phone, I noticed my lock screen actually becomes more color accurate (in my opinion) for 1 or 2 seconds, then it suddenly goes back looking kinda washed-out.

From this, I hypothesize that maybe MIUI uses some kind of special AMOLED drivers when booted which causes the screen to produce the unwanted backlight. So I tested by changing my lock screen and wallpaper to a completely black image, then restarting my phone. What I found out was that indeed, the screen issue COMPLETELY DISAPPEARS on the first 1-2 seconds of booting, and then it comes back again after that and stays until I reboot the phone again. Also, I found that on the boot screen itself, the screen issue doesn't exist at all. The POCO and MIUI logo appeared with absolutely no screen backlight.

This leads me to believe that maybe this really is just a software issue, and I am hoping that if there would be a custom rom (because I doubt MIUI would fix this soon) for this phone, it would completely eliminate this issue once and for all.

I got that too man and i am so confused ...even on full black wallpaper or reddit or really dark grey i can see a white tint or spots i cant describe it actually ..
I dunno what is this actually but i got this on three devices ..
I have asked everyone on Telegram group the denied it and say they didn't have such an issue ..even i told them that i have this on three devices ..
I general screen is stunning colors are so great but in dark grey and full black screen or any black screen it sucks ..
Can you feedback please if you had a solution or know what is going on and what is this issue ??

I can confirm too that on miui logo on starting device nothing is wrong ...i dunno if it is a defect screen or a defect driver or a backlit issue ...
Have you discovered anything bro ?? Please feedback man ...
Btw i had screen flickers but after updating to 13.0.9 and restarting nothing is wrong now .

 

[HfTFranz]

I dunno what is this actually but i got this on three devices ..

Which 3 devices? Are they all POCO X4 Pro 5G as well or are they other Xiaomi products? Also when did you order your X4 Pro and which color is it?

Unfortunately, I also still have not found any solutions for the problem as well. I am planning to return this soon (to Lazada) if there's no update that would fix it (I doubt there would be). For now I am simply trying to find similarities so we could potentially point out the issue.

Yes all of them are Poco x4 pro and i got them in Lebanon from a retailer he told me that this issue is not under warranty ...
I will unlock bootloader and try custom roms and eu rom to see if this could help by any chance ...
Maybe they are using a very cheap amoled display or it is really a huge software issue ..
Is your phone a global one btw ??
Did you try a custom rom or eu rom ??
I am afraid that this issue will get bigger and the screen is going to break or something ..
Btw why there is no gamut wide p3 option in the settings ??

 

[tornido066]

Btw have you contacted Xiaomi ? I tried to reach the feedback team but they didnt even respond at all ....

Coming to you with a new information !
Go to settings to system apps updater..it doesnt have any white spots or any issue ! The black there is a pure black ! Please try and feedback bro ...

EDIT : the only possible solution to this in my humble opinion is that they must increase grey level in dark mode and let us enable P3 option in settings,i guess the pictures causing this issue is not 100% black so that's why it is happening.
A.w they should allow us to enable or disable p3 option since the device SUPPOSED TO SUPPORT IT.

Yes, my phone is global one. I have not tried to custom rom it yet.
I am also wondering the same thing, why there is not P3 option in settings.

I have, and just like you, they were not very helpful. They only mentioned I should send it to an authorized service repair center, which I did, and same with you, they did not exactly acknowledge this as part of warranty and only did software updates for it.

I tried going to the same menu and unfortunately mine still has white spots in that area. (Maybe your brightness settings changed? Because the issue only really appears on certain brightness levels)

I guess we should wait or use a custom rom which supports p3 option ,try this bro :
First raise brightness to exactly around 40% then totally switch off the phone ,then try and check that menu i told you to check before ..
Btw my device had like a free from white spots hour when i did that !

But after watching a video for about 15 minutes the issue does come back unfortunately ..
To be honest this issue is not ruining anything for me ,i mean the colors are really good and vibrant and i am enjoying every video i am watching at my phone,i just dont want this to become bigger or damage the screen for real lol.

Bro do you have this white spots in netflex on main logo ??

 

[tornido066]

Feeding back again ...my three devices are not usable at all using 120hz ...the issue is getting a lot worse on 120 refresh rate and the screen will flicker after 2 or 3 hours ..
This is so stupid i will never ever buy a xiaomi phone again.

 

[HfTFranz]

Bro do you have this white spots in netflex on main logo ??

Yes, white spots exist at all times as long as the phone is turned on. I notice it even for my always-on display.

Yes, the flickering indeed worsens at 120 Hz.

Just like you, I have also decided not to buy Xiaomi products ever again. Quality control is abysmal. My brother owned a Redmi Note 10 Pro and his SIM slot stopped working after just 2-3 months. Because of these scenarios (including yours which you had 3 phones with the same exact screen problem, along with a fishy warranty), I have no doubt that the problem is with Xiaomi's quality control in and of itself. I guess they had to cut corners somewhere. Maybe others got a good deal out of Xiaomi, but with the risk of having a problematic device, is it really worth spending for a company that obviously does not value quality? Anyways, I will definitely be attempting to return this to Lazada. I hope they will accept and refund it.

I also have the same problem. Since i have used Mi A3 for a very long time so, I can tell how amoled screen looks like. But in my Poco X4 Pro 5G i am facing the same issue as you are facing.

Can you give me your no. I aslo have the same issue

I don't want to disclose my number. However, I guess I could give you an update. I filed for a return to Lazada (an online store) and I am still waiting for their refund. I hope they manage to replicate the issue under a very dark environment so I could receive my refund. Anyway, so the phone is not with me right now. I'm sorry, I cannot do much to help you.
