Sensors do not work

I deleted the sensor folder via twrp to see if it works in a custom ROM, I went back to miui and installed the rom via flash clean all and even then the sensors do not come back, please help me

You can reboot into fastboot mode then into EDL mode.
fastboot oem edl
Then flash with the fastboot method. Your sensors must go back.
Regards.

Not working for me...

I had the same problem, I recovered the sensor reperstoire of our redmi 4A and it works after removing the file sns.reg (and that it) reboot.
only since it works only with the cddroidandroid rom.
with other rom the rotation does not work ?? !!. if a person can post the sensor directory for AospExtended I am a taker

Hello,
I solved the problem by reinstalling the ROM MUI but developer version (http://en.miui.com/download-319.html).
then flash the custom rom of your choice

K20 Pro popup camera problem

So after trying Xiaomi EU, MiGlobe Rom and Android Q Beta
I decided to flash back to MIUI 10.3.8 via fastboot
Somehow my front camera won't open properly, it kept saying "Can't open front camera, please calibrate".
And when I press Calibrate, popup cam goes up and down 3 times in a row and says "Can't calibrate".
Any idea how to fix this?
EDIT: Must be the fastboot rom I downloaded. Other rom's front cam worked fine...

I am having same issue. Initially I thought it was hardware problem.
But I noticed it seem to be related to software.
Took few restart of camera app and sometime phone restart, for it to work

same problem here
just came from Android Q beta from Mi Global Home, and I decided to go back to MIUI china. The problem occurs after flashing the v10.3.15 china ROM.
Any ideas to solve this?

Did you install a fastboot ROM or go straight to the latest recovery ROM. If you went for the recovery, then I suggest installing the most recent fastboot ROM, then upgrade to the latest recovery ROM.

I wiped all partitions via LR. Team TWRP, and flashed the most recent fastboot ROM. Still doesn't work
after analyzing for like 3 hours, I noticed that all sensors are also not working (Gyro, Accel, Proximity, etc). I googled it and found the solution. Here it is:
by flashing persist.img (from the extracted latest fastboot ROM) to persist partition via LR. Team TWRP, all sensors are working fine. Even the camera's calibration now works perfectly

I've got same issue, coming from Android Q beta. I've put the Indian rom and I thought that this is the issue.

Problem solved! I flashed via miflash the Chinese rom, in fastboot and the front camera was working. Then I've put the Indian global version and front camera is working fine now.

Once done!! My device can't use rom (EU, Miglobe, Indian fastboot rom) except China Stable !! Boot is used for the first time, reboot the device it will stuck into TWRP (eu, miglobe), Mi Recovery. Format data can re-enter the system but continue to reboot the device and it will be similar. Go to the log section of TWRP, the whole message is unable to find crypto footer , erros opening data/data.... !! I do not understand which step I made wrong !! Sr for my bad Englosh

How did you manage to flash persist.img file? Just one file from the ROM or like in the link below?

In L.R TWRP, we can flash other kinf of partitions (like persist, for example)
I always used the "persist.img" file of the stock ROM (installed via fastboot). I trasfered it from my computer with ADB. The command is:
Code:
adb push [I]the_path_where_you_stored_the_persist_file[/I] /sdcard/
To to that, go on "Install"->"Install image"->Now choose the persist.img file-> Choose the "persist" partition -> "Flash image" -> Reboot
Then just wait for the MIUI to tell you to calibrate the camera, now it should work!

You can't show them up. The only way is to change TWRP, hoping that is supported

Facing issues with camera pop up calibration and sensors (proximity) after reverting back to stock miui v10.3.3 (Raphael India through fastboot & zip) after flashing android Q Eu rom.
when flashing persist.img through fastboot it gave write protected error. Through LR TWRP, it didnt show any errors but problem is not solved.
I couldnt flash chinese rom through fastboot, faced error saying expected device is Raphael not Raphaelin.

try flashing 10.3.16 chinese rom via fastboot yesterday i flash that rom and it fix that problem in my k20 Pro

autorotation / accelometer stops working

After boot the accelometer stops working after a few minutes, so autorotation is not functional.
I found that this i maybe a bug in miui 10 and also other devices, some users say when you google this error.
IT seems to have to do with autobrightness setting. I tried some things but did not find a solution yet.
eg I tried this: http://en.miui.com/thread-458462-1-1.html
My question is, is this still a bug or I am the only one who has this issue?

I am facing the same issue. What ROM are you using?

I´m on raphael_eea_global_images_V10.3.1.0.PFKEUXM. There is an update to V10.3.3.0.PFKEUXM, but this has problems with TWRP and I need this.
A solution for many ist, that the persist.img has an error and to flash persist.img again through TWRP or fastboot. But when doing this I get an error "partition is write protected".
Look here: http://en.miui.com/thread-312976-1-1.html
Maybe a dirty flash of the full rom is a solution, but I have never made this.
It has something to do with automatic brightness. I also tried this, but didn´t work:

It´s important to know if this is a general bug or we need to flash rom again. I don´t know....

Thanks for the insight.
(I flashed latest fastboot rom using miflash tool and auto rotate was broken.)
Flashing persist.img has done the trick. My problem is solved.
Here is what I did:
My device is raphaelin, that is k20 pro Indian.
I downloaded latest fastboot rom for raphaelin and extracted persist.img and flashed it using TWRP 3.3.1-15 Unofficial by mauronofrio. Problem solved.
Hope the same works for you.

Flashed TWRP you mentioned, flashed pesist.img and sensors work again. Before that, front camera calibratet itself , but then everything works :good:

Sensors don't work

I was in Bliss ROM and wanted to do a clean flash so I wiped system, data and cache and installed ROM, Gapps, Disable encryption zip and Magisk but when the ROM booted the android setup crashes and didn't go past there. I flashed again following the instructions for that specific ROM but the sensors didn't work only the camera so I flashed a persist image but now not even the front camera works, how can I fix it? Please help
Could someone please send me their persist/ persist backup?

Question Sensors not working properly after brick

I recently bricked my RN10s and then had to flash stock ROM using the SP flash tool now the sensors are not working properly.
The device turns its screen on and off because it thinks it's being picked up.
The sensors used by google maps show that I'm rotating constantly.
I am new while flashing on A/B partitions and thus ended up bricked, any help will be highly appreciated. I was trying to flash pixel 4 android 13 GSI A/B and also tried dot os but it seems like my device's flash memory after the brick is not working properly because it does not boot into custom twrp by the command Fastboot boot TWRP.img.
looking forward.

flash stock rom and done

I flashed the stock ROM using sp flash tool and tried with the mi flash tool but same results.

I think it might be due to corrupted persist partition, I never custom romed a device but have been researching for my RN10s and I read that persist contains the sensor data control and l1 certification that's why you need to back it up in case it corrupts. Sadly you can't flash persist from the internet since it's unique to every phone if you flash it you loose l1 certification forever but get back sensor functions (I am not sure about sensor functions returning)
Also there is a tool to fix corrupted persist so do research it but whatever you do make sure you are 100% certain it's what you want changes to persist are permeant (except if you backed up persist before the brick in which case just flash the persist backup)
V.I: as I said I never flashed a device and don't know much about it this is what I read through reddit and research, take it with a grain of salt and do your own research aswell

alright so I did some research and re-flashed the persist file from the Fastboot IMG and got the z-axis moving again of the gyroscope and some other started working properly but still the rotation sensor according to google maps and compass is not working properly it's just rotating clockwise while the magnetic sensor is a pass in CIT.

This is because persist is unique to each phone and each sensor, you should have searched for the tool that fixes corrupted persist first. Anyways there might be another issue to this as flashing official tom through mi flash tool should fix any corruption in persist anyways try finding some solutions on reddit you might find something there

you flashed miu 13 rom with android 12? if does, the problem is the rom itself has many bugs in sensors, you must flash miui 12.5.16.0 with miflash and select flash_all to wipe all partitions and rewrite them

Okay will try this now truly appreciate the support thx. Tho the phone is working quite better by time apart from the sensors.

The degree sensor or smt like that is just increasing to 360 and then will start from 0 again

Any suggestions form where to download because there are lot of sites available

This is the sensor data and as you can see Orientation sensor along with the rotations third value and the z axis of gyroscope and accelerometer isn't working well so ill re-flash with the first miui this phone had and apply updates on it hopefully it will fix the errors.
Your browser is not able to display this video.

Alright so the result is the same rn I'm running miui 12.5.2 (android 11) now what I saw after reading the results from the command fastboot getvar all that there is written no after persist I was thinking if any of the redmi note 10s users could upload a back up of their persist.img and I could try flashing as it would help in knowing what is going on phones model M2101K7BG tho the point to be noted is that the mi flash said successful while phone booted on fastboot and had to use twrp to flash the recovery and again it showed some errors but after booting the phone is working

alright so I was going thru the images and I couldn't find any persistence in both 13.0 and 12.5 but now as I am now the question is how are the x and y axis keeping their value correct while z isn't so will tho ask for a persist file but just curious how is it detecting sensors then ??

That is the issue my friend each persist is made specifically for that phone it is unique to a phone not a model so if you do flash persist of a back up from a phone of same model see sensors will either not work at all or be extremely wrong

Yea I discovered the fastboot ROM didn't have persist.img and I've stopped trying because the gsi has detected it and some how some things have been fixed I've also seen. File named gsi_persist_data in /data nvr opened it but gyroscope while gaming doesn't stop and raise to wake works.
