screen flickering poco x3 - Xiaomi Poco X3 NFC Questions & Answers

hi guys !!
i am still observing screen flickering issue on poco X3 (after update) but it is only observable while using 'material island live wallpapers' or 'live wallpaper from google wallpaper'
what i observe is
1. screen tone change to yellowish (have to on and off night mode to get it to normal)
2. continuous screen flickering if i pay attention to it (observable on dark sides)
plz comment if any of you having same issue with this device or u already resolved it.
i am having poco x3 India varient screen is same on both
update ::
flickering + screen tone change is observable on two apps yet material island app and google live wallpaper ( both have same live wallpapers)
where as screen tone change on opening ANY live wallpaper app (when i am just going to apply it)
already done that google chrome method.

I have similar problem but with browsing the web. Few days ago Xiaomi share new rom update, after that everything works correcly.

I have been using poco x3 the global variant for 2 weeks now, i also use the material islands live wallpaper but i havent noticed any yellowing or flickering so far, maybe the unit you have is faulty?

Hi
Did you try to change "Settings/Display/Scheme Color" to "Standard" ?

Thanks for reaching back, i think this was issue in Indian variants i contacted service center guys they assured me to wait for updates as except few specific apps everything is fine. After update i didn't notice any such yet, as i did notice in previous update.

Oh okay that's perfect then. Since 732G is a new chip and is released alongside poco x3 thus optimizations are needed. I'm very positive regarding future updates

Yeah doing that bring back phone to normal. But after opening that app again problem used to re appear but now after update i didn't encounter previous problems yet.

Help I have screen flickering issue when manually changing brightness to minimum in a dark room (auto brightness disabled in settings). Anyone else experience this type of flickering?
EDIT: I just came across this possible solution to my specific screen flickering problem:

Wrong background shape for some popup messages

Hi all,
after the last security update (plus some bugfix I think) to G930FXXU1DQEI sw version, brand Vodafone, I'm facing the following issues on my S7 flat:
A wrong background shape for some popups and a strange black spot on the selector , only in google now settings. Please check the attached pictures
I already tried to fix them by recovery with an hard reset without success.

Hi
Definitely odd
I would flash (odin) firmware again , use home-csc ( same CSC that is in your phone right now) so you do not loose any data
After some attempts I can say this issue happens moving the screen resolution from FHD to HD.
I flashed the rom by Odin and worked fine, at the beginning.
After the screen resolution mod the issue is still there.
Moving the resolution to FHD again and switch off/on the issue is not present.

Really odd , i would not expected
Thanks for letting us know
Hi,
I can confirm this is a bug, to be honest I don't know if it was present in the previous build. I tried to reproduce on another S7 (brand tim) and it is present.
Basically the steps to reproduce this issue are:
Change the screen resolution to HD and restart the phone. Uninstall an app and check the text box shape.
Probably you will find other problem in google now search bar or settings
To fix this issue move from HD to FHD.

Updated to 1.8.10 yesterday and tried using Lens and Assistant this morning but both seem broken. Lens says "thanks for updating, we will be available soon" or something like that. Assistant freezes the phone and won't open at all.
Anyone else have this problem?
Agreed that fps is faster but haven't noticed the other two.

Happens to me too. Mostly when I go home after browsing the net.
Battery life after update now halved. Not a good update. I reported to support but doubt there will be a solution. Anyone else having poor battery life ?

A double tap to turn off the screen works but on the lock screen. You will wake up with a double throttle to wake up the screen and extinguish it with a double thump.

For custom launchers, try to clean cache files. I had faced some issues before cleaned caching
No issues after that, even in the duration of battery life

POCO F1 Screen Retention/Ghosting Image on custom ROM/Kernel [FIX]

Issue:
1.Some users (like me) must have faced issue of screen ghosting or retention in which if the device is used at max brightness, they see a ghosted image on sides of their phone. (Especially visible when switching from a light theme to dark, for eg, going in chrome incognito mode you will see it)
2.Usually it happens after flashing a custom ROM or kernel.
Fix:
Method 1:
1. In case if its a custom ROM, go to Settings > Display > LiveDisplay
2. Set the Color Profile to ‘Standard'.
3. Go to color calibration setting and set the following values:
Red at 90%
Green at 90%
Blue at 90%.
4. Keep the display screen of for some time (15 min) and boom! Issue solved.
[Note: Max brightness may feel a little less than before but its still better, you will get used to it]
Method 2:
1.In case you have a custom kernel, you can refer to other threads or manually set the values of Red, Green and Blue by yourself by using a ‘Kernel Manager App'.
Just keep it at minimum than its original values.
Conclusion:
This issue is NOT a hardware issue, its a software issue that can be fixed by implementation of any following methods.
Source:
I got through some other threads of Redmi having same issue. Just the difference is in the settings I used, you can customize it as per your own will BUT make sure that the ghosting does not appear by use of that setting. If successful, you may replay
What are you talking about??
This issue is not available in Pixel exp plus pie, is this a Stock rom issue??
but i didn't experience it for whatever hours i was on stock Miui.
It is not software issue, but the low hardware quality I presume

It is not the case that every user will face it. In case if it occurs, you may make use of these procedures.
Mostly, if you use max brightness and switch suddenly to dark grey, you can notice it (in custom ROMs / custom kernel ).

No it is a software issue. I am not talking about the yellow spot issue (that is hardware issue)
This one is ghosting or temporary burn in caused due to change in the default color calibration.
I faced it before but after trying the above settings, even at max brightness, the ghosting did not appear again. So it actually works.
Ghosting does not remain forever in LCD. So its not harmful to hardware in any way. (Just buggy)

What exactly will i notice, i want to know what happens??
I agree. Screen Retention or Ghosting is mostly present on other devices (I'm not talking about the Pocophone alone but on every other devices) and can be fixed via software implementations or updates. Changing color profile and/or color settings can be a solution too.

I am neither using a custom ROM nor have done anything in past which can have these after effects. I am facing these issue or may be noticeable after the rollout of the MIUI11 ROM. So i contacted other who owns pocof1 , but their device don't have these issues. Then i contacted the service center and they reinstalled the MIUI11 but the problem persists.
So then i thinking of a screen replacement since i m on a warranty period so should i do that to solve this issue?.
Also u gave the settings to resolve the issue for a stock/CustomUI but wht for the MIUI , pls give the setting for them too.
pls answer all my queries!

This reply is pretty late, sorry for that.
1.You need to be rooted.
2.Download ColorChanger app from PlayStore.
3.Give root privileges.
4.Decrease the color in Custom1/Custom2/Custom3 by long tapping to these values:
R:240
G:240
B:240
S:1.00.
5.Save it (top left corner)
Con: You need to apply this every time you boot into your device.
You can upgrade to pro and enable “Activate on boot" from app setting to make this happen automatically.
I did it but it doesn't work, I'll consider change the hole panel
Can you take a look at the attached screenshot and confirm if these values are okay. Apart from RGB values, do I need to tweak anything else? Thanks in advance.
Oh I see, I got this problem, and realize I set livedisplay profile to dynamic. I thought my screen was wore out

Thanks in Advance.

I solve this problem on miui oficial without root, Just applying standard contrast on screen settings.

Android 11 Beta 2 Released

Just downloaded the Beta 2 OTA from google's site: https://developer.android.com/preview/download-ota#

Yup just downloaded and flashed and have root still??
Currently on it! Improvement in animation in some places, better landscape to portrait transition.
Missing clock option from themes
Music player now looks better, I think no more an experimental feature.
Final api released good for developers.
Recently screen tweaked a bit no share option anymore.
Yet to find other changes

Updating my Taimen now. About to be in a meeting so I need my Coral working, do will update later.

Problems I have noticed are
The screen flickers a lot especially when using dark theme and a dark themed app.
I'm also missing new media controls.
Anyone got these problems?
does the navigation bar still remain on the home screen even on beta 2?
Flickering here too

I have the flicker issue too, media controls are there though.
I've noticed there's no longer the option to force 90hz now either in developer settings which I presume would resolve the flicker issue.

Just done a quick test and turned brightness up above 70%ish the flickering stops or just isn't noticeable.
Flicking is so annoying.. is there any fix?
Maybe custom kernel? I can't watch on this stroboscope
Anyone got Magisk working on the new beta? The canary build that was reported working on beta 1 isn't booting for me. (I never tried beta 1 myself.)
Here is my experience...
1) The flickering screen is annoying
2) I had no problems rooting via Magisk
2a) After rooting my Messages app stopped receiving messages but I was able to send them without issue
2b) I could not update apps from the Google Play store. It would just say "Downloading" but nothing would happen
2c) The Google weather widget on the home screen would not show the weather nor would it take me to Google weather when I clicked it. It seemed disabled.
I have since re-flashed the latest Beta but didn't root. All of the above issues, aside from the screen flickering, have been resolved,
Lots of flickering
Terrible flickering...
The flickering exists also at Beta 1 but only at very low brightness (environment and system brightness). Now screen flickering regardless of environment and system brightness (except at extreme high system brightness...) as long as background is not totally black.
Flickering sucks! OMG! No media controls here but do have force 90hz option still
Hopefully the flickering issues can be fixed with a 2.5 patch or maybe play services/kernel update ??

I have tried a few ways no luck yet.
As for other people the flicking screen I have it in this beta . I had it before Beta too, It's the 60hz - 90hz refresh rate. Sucks to say but if you disable it fixes the problem.
I don't see the flickering on my device. Yes to using dark mode, force dark mode, enabling 90 Hzv display (no more force), and playing a couple games at well as watching videos, reading news...
It never shows. Or else I am not recognizing it - and I'm pretty sure I know what flickering means, so....
I do use figure mode to automatically pause most of my games and SoS I don't normally use at work during work hours, so maybe that is why?
Or else something else I might have done?
From Coral, with Tapatalk
I thought mine wasn't doing it to until just now. In dark room and looking at chrome settings while using dark mode. The grey background flickers like crazy... On a positive note at least it's safe to to back to Android 10 July without face unlock breaking
Anyone who is missing the new media controls, found any way to get them to work yet?

Question Ghost touch issue

Hey guys!
I'm currently on ArrowOS 07.09 build with firmware 12.5.1. In the last 2 weeks I got ghost touch issues quite frequent. The phone starts to recognize touches crazy fast without me touching it and doing random things. I have to lock the phone with the power button to make it stop.
Does anyone else have or had the same issue? Is it a hw or sw related issue in your opinion? Any tips, ideas, working methods are welcome to make it stop.
Thank you!
It's mostly a SW issue , but it can also be a hardware issue(extremely rare),change the room to pixel plus UI 3.7 most stable(tested by me).
edit: also less bugs than others and very fluent.
I had the same problem. The solution is to turn off the Game Turbo app. Your problem will be solved.
Mine problem is solved by send it to service center. They replaced screen module.
Reporting.
For anyone facing heavy ghost touch issue, you might want to try indonesian miui 12.5.2 rom (rjuidxm)
Previously I got ghost touch on xiaomi.eu 12.0.4, 12.5.1, 12.5.2 to 12.5.4, few arrow OS version, to the point that I got tired of testing backing up restoring and doing clean flash everytime, because this is my primary phone I use for daily driver
But now I have used miui 12.5.2 ID for 9 days and haven't faced any ghost touch.. I also always turned on show taps on dev options so that I'll know if theres any ghost touch, and theres none so far (I have 6/128 unit with tianma panel)
But there's huge performance drop in this rom, game that I play (PGR) have noticeable frame drops where theres none before, others also reported lower performance on genshin impact
i dont have such issue
at least i dont notice it responding to "something" when i just leave it on table
btw, clothing contacts are also contact

For me, it has helped now to set the refresh rate and the screen to 60 Hz. We'll see for how long. All other activities did not help, including the game turbo exclusion.
Unfortunately, but with the 60 Hz refresh, the touch has gone crazy once, but it probably happens less often
well it depends on what screen you have, if it's tianma the ghost touch is "normal" and will only get worse because is hardware related, if it's Huaxing it's probably software related or (very bad luck) defective screen...
you can know your screen:
If you are on a Custom ROM or have installed Magisk:
1. Download Device Info HW application
2. Tap on 3 dots in the right corner of the application
4. Restart the app
5. Check LCM (above touchscreen)
dsi_j20s-42-02-0b <- CSOT/Huaxing
dsi_j20s-36-02-0a <- Tianma
If you are on MIUI without root:
1. Open your dialer and enter: *#*#284#*#*;
2. Open a File Manager, go to ~/MIUI/debug_log/ directory, you should see an archive named bugreport-yyyy-mm-dd-HHMMSS; (Date and time when bugreport was created)
3. Extract that archive, then extract another archive which was in bugreport zip, its name should look like this - bugreport-vayu_global-RKQ1.200826.002-2021-05-27-13-32-52.
4. In bugreport-vayu_global folder open dumpstate_board.txt and type in search tianma. If it's found, you have tianma, otherwise huaxing.
Thanks. I checked my tianma. I found such a coincidence "MDPPLATFORM_PANEL_TIANMA_NT36672C_J20S_LCD_VIDEO" How do you think to advertise the phone?
Well there is many reports that it fixed with MIUI 12.5.5.0 global latest update. ( confirm it, please!?)
For me never happened "tianma".
Regards
Jestem na miui 12.5.2.0 EEA i nie ma jeszcze aktualizacji do 12.5.5.0

yes my phone update the MIUI to 12.5.5.0 and everything its good and smooth but I'm a little scared, if another update ends up breaking the device. On the other hand, I activated the option, to see the touches on the screen through the developer options, and detect that when I use YouTube and try to put a video in landscape using the button in the video, a single ghost touch appears in the middle of the screen, it does not affect at all apparently, but it seems to me that the ghost touches were not corrected correctly or in its entirety.
