I am considering changing to an open source smartphone. However there are some apps that I must have, like authenticator, mobile bank and government apps. Does anyone have any experience with any of these brands, what are they like and also is it possible to install android apps?
That is too bad. Scary what the government can do. Sounds like you will need two devices if you care to have one that is open source.
Requiring 2FA is a good idea though.
