Hello,
First firmware I was using was Chinese firmware and it worked fine (OTA was updated to 10.3.17). I used it until I got permission to unlock my bootloader. Then every other firmware from Mi or Xiaomi.eu have this problem. I cannot calibrate compass - in compass application or maps app my direction is spinning all the time counter-clockwise. Spin speed is ~5 spins in 3 second. Tried to clean compass app cache - do not help.
Tried to test sensors - in "all specs" click 5 times on Kernel and enter CIT. Result - Accelerometer looks working fine, Gyroscope - Z axis shows -7 all time, Magnetic sensor - spins counter-clockwise all the time.
My bad I have formatted all system before flashing firmware, that may get lost of original "persist" and "vendor" images if they are required.
Summary - looks like gyroscope sensor is failured - Z axis shows -7 rad/s all the time and that makes some functions hardly usable. Compass included.
Phone did not had any drops all the time. Only magnetic car holder was used, but cannot remember it happened same day. It was used with previous phone too and it still worksfine.
I have tried many Cn stable Roms, Indian roms, EEA, Xiaomi.eu. Installing in fastboot mode. No one firmware works fine with compass application.
Several fastboots tried:
Code:
raphael_eea_global_images_V10.3.1.0.PFKEUXM_20190723.0000.00_9.0_eea
raphael_images_V10.3.6.0.PFKCNXM_20190516.0000.00_9.0_cn
raphael_images_V10.3.8.0.PFKCNXM_20190601.0000.00_9.0_cn
raphaelin_in_global_images_V10.3.3.0.PFKINXM_20190711.0000.00_9.0_in
raphaels_images_V10.4.1.0.PFKCNXM_20190827.0000.00_9.0_cn
Recovery ROMs tried:
Code:
xiaomi.eu_multi_HMK20ProMI9TPro_V10.3.17.0.PFKCNXM_v10-9.zip
xiaomi.eu_multi_HMK20ProMI9TPro_V10.4.4.0.QFKCNXM_v10-10.zip
Maybe you can suggest any possibility to fix this? I assume that should be software issue.
Did you ever flashed Q or Downgraded from Q to P?

Originally was Android 9. My first ROM flashed was Xiaomi.eu V10.4.4.0 - Android Q. Later tried Android 9 and Android 10.
I have just tried to install Lineage ROM over Stable CN 10.3.17 ROM - it misses compass app, but random app from net shows that compass works good. I mage a backup of all partitions. Maybe it is possible to restore some partition over working Xiaomi.eu ROM to keep Miui working and make compass work too?

Like others, most probably you broke your device sensors while downgrading. Do a clean restore of Android Pie with a fastboot image. Extract the persist.img from the fastboot package and flash it to the persist partition through LR TWRP. Reboot and Calibrate your front Camera and let other sensors Calibrate aswell. Do a hardware test (*#*#64663#*#*) and you should be able to see values for x,y,z axis for most of the sensors. If the compass still doesn't work, you might have a defective item.

Redmi K20 Pro persist backup required
I have tried steps you suggested and works everything except Gyroscope. As before. I have made testing using Sensors Multitool. Rotation vector Z is swinging from -1 to 1 all the time even if phone is still. Gyroscope info shows Z axis always -7 or more. Gravity reacts to movement, but unnatural. On Q everything worked until downgraded back to P.
I have found useful topic about this problem - https://forum.xda-developers.com/pixel-3-xl/how-to/android-10-sensors-bug-t3964904 . Reading through maybe will find something useful for my phone. I have never rooted my phone. Used Magisk few times. Persist.img I used was from Android 9 Chinese ROM 10.3.16 (As my phone is Chinese version). Persist.img was installed only with TWRP, it showed no problem when processed it.
Maybe someone can share backed up persist partition of Redmi K20 Chinese version? Hardware version in "All specs" page shows "Hardware version: V1". I got instruction to retrieve it. The following should put an image of the persist partition on the phone's internal storage. It should be executed on TWRP from Advanced > Terminal window.
Code:
dd if=/dev/block/by-name/persist of=/sdcard/persist_backup.img
I have made md5 checksums of all persist.img I have in each firmware. Despite file size is same, content each time is different.

User which requires sensors fix should do following:
1) Open root shell
2) dd if=/dev/block/by-name/persist of=/sdcard/persist_backup.img
3) Copy new persist.img to your sdcard home directory
4) dd if=/sdcard/persist.img of=/dev/block/by-name/persist
5) Reboot device

So, maybe someone with K20 Pro CN version can share their persist.img file with me and others?
Hey, I have the same problem and this is getting me crazy. Have you solved the problem?
No, I got tired trying and now use phone with this problem. I get to much effort live without my new phone as I need on my daily life. Lineage os is not interesting to me too use for working sensors but without miui.

hmmm i am seeing a pattern , where many had problems after flashing roms , odd , anyway how to tell needle on the app is really facing north ?
It occurs also on my Mi 9T Pro with official global ROM... Compass spins constantly over Z-axis. It is especially visible for instance in Google Maps and annoys a lot. I think I will wait till MIUI 11 release and then maybe return this phone unless it will recover.

Yes, looks like it occurs with officials ROM too if ROM was uploaded by FASTBOOT mode. Stock sensor settings gets rewritten with universal settings which do not work as desired.
Yes it seems so. The worst thing is that, it was working just fine at the very beginning, compass was lost just few weeks after I bought the phone
In the meantime maybe there were two official OTA updates, nevertheless I cannot recall what could cause loss of this functionality.
Thanks for your comment anyway.

Even mine was screwed up..I taught I'll have to take it to service centre ....I had formatted system ...and when I installed fastbiit ROM..the gyroscope and accelerometer was not working.. unfortunately I had relocked my bootloader and had to wait for 30 days to flash persist file....so I just gave factory reset from settings a try..and it worked

You did factory reset from ROM version you have uploaded via FASTBOOT earlier and that worked? What persist file you have used? And how compass functionality - works? Fastboot ROM version accelerometer works fine, but compass fails.

At first my gyroscope also wasn't working....I didn't flash any persist file but now I can see that the compass is buggy... And also the video recording is buggy.... Hope after flashing miui 11 upcoming update it fixes things
I have the same issue. Don't know how to fix it. Am already using miui 11

Hi everyone
I Update my MI 9 Global to android 10 ( MIUI 11.0.6 Stable QFAMIXM) but after setup finish and phone rebooted the touch screen dont work any more.
one month ago my phone touchscreen broke and replaced and worked great before update (android 9 on MIUI 10.2 I think )
but after update it does not react at all . i installed custom recover twrp and installed new rom from xiaomi.eu but nothing changed. :crying:
I connect optical mouse throw otg cable to phone and every thing works normal. sound , network , wifi , bluetooth , camera , .... all work great but touch screen doesnt respond .
I think the problem is kernel dont load driver for touchscreen properly or the new android dont load firmware for touchscreen.
it is dmesg output :
https://pastebin.com/i4Cfyden
if you look at dmesg log you can see some line with error like :
"Firmware in the chip different from the one that was burn! " and "fts_fw_update: firmware update failed again! ERROR 82080B02"
please help me to solve this problem . if I have to use custom kernel or change and compile the driver for new touchscreen ??
based on dmesg log (Read FW from BIN file st_fts_f1.ftb !) firmware must be in file "st_fts_f1.ftb" but I cant find this file in phone memory. I have root access to phone and searched all folder ( including vendor and persist partitions )
Just flash the previous Android version that worked. It sounds as if you bought an aftermarket screen with different hardware.

I Installed android 10 GSI Rom from https://github.com/phhusson/treble_experimentations and touch screen and finger print sensor start to work !!
but GSI have some problem and limitation for mi 9 for example battery is not so good and full screen gusttures dont work. how is possible touch screen works with this rom but not by official Android 10 ?? If i can use some part of GSI with Official or Xaiomi.eu roms to enable touch screen ?
Maybe pocket mode is interfering on stock ROM?
Try a old stock Chinese ROM?
Start from very old..

How Can I test that ? And yes all android 9 ( official or xiaomi.eu ) work but have some minor finger print problem . But The only Android 10 that has not problem with touch screen is GSI rom even GSI v220 ( based on android 10 ) works . I dont know how this is possible ? I based On this I am sure the problem is software not hardware . A question Sir : If touch screen driver in Kernel (boot.img) or in vendor ? I think If I can merge vendors or kernel from android 9 with system and other from android 10 the problem is solved. Thank you and Please any Of your help and info can solve the problem
I have the same problem, Mi9 running MIUI10 Global, want to upgrade to MIUI11 but after update the touchscreen doesn't work, only via otg USB mouse. Tried to flash MIUI12 ia TWRP, again touchscreen doesn't work.
Have you solved the problem?
Same problem
Guys, has anyone managed to solve this problem?
Mi 9 After changing the screen the touch locks after a few minutes of use
My Mi 9's screen broke and I had to change it, but after a few minutes of use the touch simply stops working.
It happens a lot when I lock the screen, and I try to unlock it after a while.
Guys, I've been looking for the solution for some time but I just don't think so. I even found some forums saying to downgrade to version V10 but I still have this problem.
The screen is original, imported from CHINA and is of high quality.
Has anyone had this problem and can share the solution?

unfortunately i dont find any solution yet. and i think no one is kind enough to help us . Now I am sure it is kernel problem. i installed GSI android 10 on android 9 vendor and touch screen works great ( but have some other problem with GIS like cant recieve or send sms messages) So the problem Is kernel used in android 10 . even i installed Quantic-Kernel on aosp and after that again touch screen stop working.Please if any senior member who is familiar with android kernel help us to compile or change touch screen driver used in version 9 and solve the problem . Please Please

You can install new Rom and see if the problem gone or no . I recommentd you install new stock android 10 with MIUI 12 or xiaomi.eu rom .
If after new install problem exist it may be some hardware problem . Even before install new rom you can reset factory your phone and see what happens ( backup up your data before reset factory)

Right. Dude, thank you very much for your help. As I live here in Brazil, there is almost no content talking about this error. Thank you one more time!!
After upgrading to MIUI 12 Global OTA yesterday, fingerprint unlock stopped working. When I select fingerprint unlock in settings to switch it on and enter my PIN, phone goes dark and restarts (MIUI splash screen). Any suggestions? Phone is stock and not rooted.
Additional info: from CIT menu I ran the fingerprint sensor test. Result shows: all success. Next test (Fod fingerprint input test) gives following message: Your phone has password can not enroll fingerprint information
Not sure I understand the result of this test. Phone of course has a password (required to set fingerprint unlock).

I installed MIUI 12 through OTA global version. I am not rooted and therefore not easy to reinstall. I might try factory reset, although that also involves some extra work...

Too bad, but my AoD is working and no issue.
See, the cause of fingerprint bug on miui 12 I guess is replaced Lcd. Let's see if anyone fixes this bug
hi guys i have the same issue, please teach me to fix this please i badly need your help
I have the same problem, also changed the screen. I hope some one find a solution for this.. Now i went back to miui11
Eu também estou com esse problema, alguém tem que saber a solução.
I have the same problem. I updated from a fresh MIUI 11.06 (i wanted to remove orangefox cfw to do OTA update) to MIUI 12 via ota update. I didn't register fingerprint in fresh 11.06
OTA went perfectly but when I tried to register fingerprint it crashed and rebooted.
My screen was also replaced a couple of months ago, if the service center uses an original screen? I don't know. I should ask. They provide 2 year warranty on installed screen so maybe they should replace it with REAL one!!

Yah, could be your phone screen not original. Did your phone screen support 5 or 10 multitouch?
and if you already replace your screen on service center and try the fingerprint please update to this thread, I want to know the reason of this bug.

I asked the repair centre if they installed an original oem screen or not. Still waiting for reply.
10 point touch does work though.
Same problem
I'm having the same issue with my Redmi K20 Pro. My display was also replaced to a not original one and fingerprint was working fine at MIUI 11.
After updating via OTA to MIUI 12, it crashed every time I tried to unlock, restarting the device with an infite loop. After that, I made a factory reset, then configuration reset and reinstalled the OTA package but it still won't work.
Hope we can find a solution to this problem!

Hi,
I've bought a used MI 11 (8gb/256gb) phone. Did not pay attention during buying, so the issue might be present from the beginning: the gyroscope, accelerometer and magnetic sensors are not working. Steps I've already took:
- I've entered into CIT and I've went to calibration: they all fail. More precisely I open the e.g. gyroscope and then wait and nothing happens. Same with the other two sensors. Camera calibration also fails, I assume bc of one of this sensor is not working.
- I've already flashed persist.img via TWRP (i know, I have lost L1, so DON'T DO IT!) and that did not help.
- Tried fastboot / twrp flashing different roms (xiaomi.eu, xiaomi global, xiaomi chinese, xiaomi europe).
Is there anything I can do here? Is it possible that these 3 sensors are all physically broken? Are they actually just one sensor?
thanks!

I'm not sure how is this related to my problem in any sense, but thanks, I am not planning to close BL.
the standard of the stock tool is to close your BL

I understand, but not the opening/closing the BL is my problem. Sensors are not working
iknow its a tipp with the bl, flash a tgz file then your problem with sensor are end, the tgz file make your system complett new it is better than flash a recovery rom the different is more than 1gb of partiion repair

Persist partition was damaged. Classic problem. Reflash it.
But you loose wideline certificate. I warn you. (Wideline=Netflix in hd)
Flash a original rom with flashtool from Xiaomi without locking bootloader .
