Anyone that's already updated to HyperOS.. I've got a 12S Ultra and running it in the US with AT&T. The only way I've been able to use it was due to Xiaomi having a "disable VoLTE check" dialer code(to stop AT&Ts white list from blocking the phone). So I've been kind of afraid HyperOS might get rid of this feature. Could anyone check to see if the dialer codes still exist?
