You should go into recovery and wipe user data and cache if you have not done that.

Mic fail in call - no sound transmitted

Hello,
This has been driving me nuts. I can't be heard in normal calls, the mic picks up nothing.
I am using global 9t pro.
I have tested the hardware and the mic is working. Speakerphone works also. All roms tried present the same problem (stock, lineage, Xiaomi.eu). I have now clean flashed stock MIUI 10 and updated to 11 and problem remains.
I've read there can be sim reader problems, but speakerphone seems to work. I've read there can be audio routing problems relating to headset with mic being detected, but I can't find evidence the phone thinks there is a headset connected. I've disabled Google Assistant and the problem remains.
What puzzles me is that even after a complete clean flash of stock rom there is no improvement.
Any advice would be greatly appreciated.
Thanks

Hello I had a similar problem, my autorotation and mic started to fail and I got confused, after some research it turns out if I flash MIUI 11 and go back to MIUI 10 a partition called persist gets deleted and it completely messes up your sensors and it won't get fixed regardless you flash another rom, what I did was download fastboot rom and flash it. If that doesn't fix it extract the persist.img from the rom files and flash it through TWRP and it should go back to working. Wait now that I think about it you try flash persist.img from the files and if it doesn't work then you flash the fastboot rom. Good luck

[Q] Mic Problem in Android 10

First of all, I'm running MSM Xtended v9 dirty flashed from v5 which was clean flashed after Havoc OS Pie rom some time ago.
Okay so here is the problem as specific as possible.
At first, after doing an online call using headphones (Either via Whatsapp, Messanger, Discord) the mic would suddenly stop working, no voice input would be detected whether its Voice Notes, regular calls, google assistant or any other app that detects voice input. This was back on MSM Xtended v5, which was Clean flashed. The problem then persisted and turned into the mic doing the same thing even without the headphones, then onto doing it again for regular calls too, not just the online ones (so that means I have to reboot after every call). I thought it was a problem with my android version so I upgraded to v9, dirty flashed. I wanted to opt for a clean flash but I had some data on apps that couldn't be backed up at the time. Problem still remained and now the mic suddenly stops working after reboot for no reason without making any calls.
Obviously, as every developer recommends I thought to clean flash the rom again, and prepared myself to backup everything and lose that which I can't back up. Then while looking for a different rom, I noticed multiple people having the same problem for different ROMs, though all were Android 10 ROMs.
So I wanted to ask, is there any solution to this problem? It makes the device basically unusable without any mic, and I do understand that not everyone has the same problem but when I saw others having it I realized it might not be specific to my unit.
Anyone trying other Android 10 ROMs without this problem? Should I downgrade to Pie? Any help would be appreciated, please.
If you recommend downgrading please tell me how, as I seem to have forgotten and can't find the method online (it may be there but I haven't seen, I apologize if that's the case).
Thank you in advance.

Known issue on Android 10, most probably it is Gapps issue, so try Weeb Gapps if you don't need 'Hey Google' thing. Downgrading is not that hard on OnePlus 3T, just download OOS 9.0.6, backup your data to PC or OTG, wipe all and format data and flash OOS, that's it.

Do you solve this problem?

i started having issue with my camera after 12.5.9 update my default miui camera app would close after clicking one photo although it was working in other camera like snapchat or fj camera. But few days after 12.5.10 update both front and back camera completely stopped working.
I unlocked my bootloader to downgrade the rom or flash custom rom as this seemed like a software issue . But after a week when i downgraded to my surprise the issue was still there which implies that the camera hardware has failed . So i dropped the idea of installing custom rom and instead went to service center, now they are replacing the motherboard as its hardware issue . I am gonna get back my phone today from service center so will update you guys accordingly .
Blog Link - This is the blog link which discusses about same problem even xiaomi has accepted the issue.
Its weird that software update can cause hardware bug but what i think is that with the update kernel setting might have been changed which can cause over voltage to camera module or something. Its my wild guess i don't have much idea about it . I would love to know it from experts out here .
