Never had this problem with the EU roms.
Did you use this TWRP?
https://androidfilehost.com/?fid=17248734326145679747
With a stock rom to have all the calibration options.
https://forum.xda-developers.com/t/use-xiaomi-flash-tool.4262425/(last).
possible with twrp(zip) but more safe with this method.

Use miflash and flash a android 11 rom(tgz).
If your phone is a EEA flash EEA rom.
global to global rom.

Did you use the calibration with a piece of white paper then black?
I had this problem and it was solved with this manipulation and if I remember correctly it ended with an error but restarting the phone it came back.
You have to restart the phone after trying a calibration, trying several times in a row no longer works.

And the calibration must be done with the rom you had at the start.

It was on roms V12.2.4.0.RJKMIXM or V12.2.3.0.RJKMIXM(my phone is global version)

Downgrade your Device even from Anti ROLLBACK SYSTEM

Hello MIUI Fans,In this video I tell you about to Roll Back even on Anti Roll Back System without any Bricking or Error.If you are facing any type of issues and want to switch back to Stable So, Please like this video , share in your circle & Do Subscribe for more future updates.PLEASE LIKE, SHARE COMMENTS & SUBSCRIBE.
https://youtu.be/9wCsK_uzh1I
no english
Can switch between Anti 4 roms
Basically the video explains how you can install miui 9 (9.5.19) which is an anti 4 rom, using the updater app, from miui 10(8.7.12) which is also an anti 4 rom.
The older roms are anti 3 roms, hence they can't be installed without a hard brick.
So if you're on an Anti 4 rom, you can only install anti 4 roms, but not Anti 3.
How bout if we downgrade via TWRP is it safe??
yep safe

Download 9.6.4 recovery ROM and flash it using updater (goto system update click on three dots from top right corner and click on choose update package, select downloaded 9.6.4 recovery ROM and flash it)
After downgrading to older version just do factory reset

Sensors not working

I was using pixel experience rom but then I flashed stock MIUI and suddenly sensors stopped working. What could have caused it and how can I fix it? I want to stay on MIUI. Thank You!
Switching back to android 9 from android 10. Get back to android 11 all sensor will work again

To fix this issue you need to flash persist.img from Fastboot rom to Persist partition using Orangfox recovery- But remember after this you may/will loose widevine L1 support to L3
My compass sensor doesn't update at all
Why

Downgrade to MIUI 11

Does downgrade to MIUI 11 causing any problem with sensor lost? im planining to downgrade, just curious if anyone experience problems after downgrading?
EDIT: for those interested in this thread and wanted to downgrade..in my experience downgrading cause fingerprint sensor lost..and i was able to bring back fod only after flashing miui 12 back

Did u even try to downgrade to miui 11?
Hmm i blindly believe u...and now I lost fingerprint options. and I didn't create backup of persist.img
Hope other sensors are fine. Please in future don't answer anyone with guess and if u are not sure.
EDIT: Tried everything to back fingerprint on miui 11 but fails. All other sensor is fine even L1 widevine is ok. After flashing MIUI 12 fingerprint is back but i think it working slower (maybe placebo effect)

Hey,
When i had a trouble, or stutter on my fingerprint on my oneplus 3, to avoid that, the tips is to delete all fingerprint, and restart saving new one. Try it and tells me if it works.

I did the same thing without any FOD problem (V12.0.3.0.QJKMIXM to V11.0.2.0.QJKMIXM miflash).
But i lost fingerprint with a Weekly EU rom.
I solved the problem with this method:Flashed with miflash V12.0.3.0.QJKMIXM clean all and lock then :Go to the CIT menu press the 3 dot in the top right of screen scroll down calibrate the FOD -> place a white thing on FOD click start before next step put something black on FOD and press next...wait until finish close restart and add your fingerprint(Thanks to tze_vitamin).that's all...

i was downgrade 12.0.3.0eu to 11.0.6.0eu (clean all and lock method) and lost FOD. Tried everything to back FOD and only solution for me was flashing back 12.0.3.0. Didn't try with calibration on CIT as i didn't know for that..all i was tried in CIT was fingerprint test which failed. Thanks

yes i was using miflash to downgrade and i was downgrading from 12.0.3.0 to 11.0.6.0 and i was lost fingerprint, since 11.0.6.0 is last and only MIUI 11 for EU i was not able to flash any other 11. so i was back on MIUI 12 again to fix fingerprint problem.
Right now im using 12.0.4.0 Indonesian rom with locked bootloader and im pretty happy with it, im only missing miui launcher right now.

Surely already done:
check the permissions of the affected apps
settings / management of applications / installed applications.
Uninstalled and reinstalled the affected applications.
If you have updated roms on roms, try a clean flash with the latest android 11 version.
Yes already done i think this is micro cuts on cellular reception for exemple when i use tethering with ftp soft on my comp i can't keep connection because the connection is unstable or micro cuts on cellular datas...
Have you an idea to solve this problem i am the only one facing this issue?

Stock camera app not working

Hello,
I got a big issue on my Mi 10 Ultra, the stock camera is not wanting to work anymore.
It's black only and then refuses to launch (see screenshot attached).
I've tried third party apps but quality is not as good and I can't use all the camera modules. I've bought the 10 Ultra for it's cameras and really want to keep using it. (I do a lot of macrophotography and the 10 Ultra is amazing for this but only on the wide angle module.)
Did someone encountered the same issue ?
I've tried installing GCam but I do not managed to install apks. Theres an issue during the package analysis... (I've tried all GCam apks I could find here.)
I'm on stock EU OS with TWRP and I just activated root to try to solve the issue.
Sorry for bad english and french screenshots
EDIT: Every camera is working in the CIT hardware tests, I think it's software but I resetted the phone and nothing changed.

you mean Xiaomi Eu ROM?
If the code name is CAS,there are chinesse firmware only.
maybe try that

I got the Xiaomi.EU ROM as it was shipped with. It has a TWRP recovery from when I rooted it and got Magisk installed.

I understand this is a tutorial to change my ROM, which is not what I'm searching for as the ROM works really well. Plus I only see the CAS on this thread's links which is the chinese ROM.
Not sure what you meant.
My bootloader was locked all the time, I just unlocked it during my testing but it did not change anything.

Now in the tests, my 5x telephoto camera does not respond, so I think it's an hardware issue, but I don't think the camera is broken so I'd like to found people with the same experience.
I don't think changing the recovery will solve the problem.
Plus I like having TWRP

Flash this rom to be sure
Mi 10 Ultra ChinaStableFastbootV13.0.4.0.SJJCNXM
Just to be sure of something, I did a test. Thanks for answering all my messages but what I need and want now is info or a way to debunk the issue.
I wont flash a ROM in a language I don't understand on the phone I use every day just to test something.
I already tried resetting the phone (including dalvik cache iirc) and it did not change anything.
Plus I would need a PC and a flashing tool, this would take a lot of time...
Finally, the issue did not came with a ROM change, the actual ROM is stable.
Edit : I changed the camera module, everything works perfectly
According to my repair shop, Xiaomis are just unreliable.
