I prefer Delta Chat, but sadly video calls are experimental :(

And also there is no support for group calls.

You could just unlock the bootloader and install a GSI. Problem solved. That’s why I still buy Xiaomi phones, because they have great hardware and software freedom’ish

If you cannot unlock the bootloader, it’s not truly your phone, and Honor has a tendency to block bootloader unlocking

Mullvad Browser for the win!
