It is high noon that a mobile phone on which we can install any linux flavour, with a nice debian netinstall like interface, is developed. An os where we can run apt-get and dpkg list on the cli to see what is installed and what it does. Something not android and ideally not a brick, and compatible with arm cpus, can make calls and can do 4/5g. From there on we can develop and use open source apps that we know EXACTLY whom they leak information to.
Purism is doing this already with the [1] Librem 5.
Hmm interesting, will look at this closer. If indeed one can install a gnu/linux flavour as the site claims (had a quick read just now, not in detail), i will pre-order one.
