New [Possible] Bug - Can't make calls - 9.8.29/9.9.3

[firedeimos]

Phone: Mi Mix 2S
MIUI: 9.8.22 (working)
MIUI Language: Portuguese
Country: Portugal
Service provider: Vodafone

Hi, since 9.8.29 that i can't make any call's. I can however receive them about 70% of the time (the ones that fail say my phone it's turned off).

It started when i installed the 9.8.29, since then whenever i try to make a call it starts dialing and about 2 seconds later it says call ended, no dial tone.
I've noticed that when it happens, my cell service indicator goes to zero and displays a cross as if i have no service. 5 seconds later it reconnects.
Still can't make calls.

When using mobile data it works as it should, regardless of the build.
There's no error message nothing so i can't provide more in depth details, i think.

With 9.9.3 it's the same.

What I've tried:

- Checked the settings
- Dirty flash 9.8.29/9.9.3 over 9.8.22
- Clean install 9.8.29
- Dirty flash 9.9.3 over 9.8.29
- Clean install 9.9.3
- Flashed the 9.8.22 modem on 9.8.29
- Flashed the 9.8.22 modem on 9.9.3
- Revert to 9.8.22 (last working build for me)

Sorry for my English and for the lack of details.

Thank you for all your hard work.

Edit: Added details

Hello, sadly after many tries, with many variations of your fix i can't get it to work.
In the latest stable i can make call's, but after the 9.8.22 the problem persists...
Even in the 9.9.10 i have this issue so, i guess I'll have to wait for the next Beta to see if the problem is gone.

Thank you anyway.
