When I made a telephone call with my friend, I can hear his voice, but he can't hear mine. While chatting works normally when we talking with chatting apps, such as wechat.

Phone calls works fine on my Mi 9.
 
I had the same issue.
If you reboot the phone it will work for a while before this will happen again.
i reverted back to 9.8.1 which does not have this issue.
 
when i use 10.2.16 Stable ROM, my MI 9 has no WLAN functionality.(I couldn't turn it on). When I use 9.9.6 dev ROM, I couldn't make phone calls as I mentioned before.
 
I fixed Wi-Fi issue in 10.2.16 Stable ROM. It's caused by persist.img, (we can see error message "Find device corrupt",), Just simply install persist.img to persist partition in TWRP.

I won't use dev 9.9.6 in MI 9 anymore..
