Update: completely new installation didn’t change anything. Still, every call is listed as "Unknown number". What's more, when I decline the call, the caller gets my voicemail - as if I was talking with somebody.Guys, I've got a weird bug (not necessarily related to the ROM) - every call number is listed as unknown, including mine in the Settings. Numbers are displaying completely normal when using SMS, it’s only a problem when someone is calling me. I'm using vanilla version with microG installed.
EDIT: Found a problem - my carrier has a problem with VoLTE on. Everything works with VoLTE set to off.
