@rysiek Librem 5 is a phone by Purism, which aims to be as secure as possible with no nonfree microcode on cpu, separated baseband/cpu, and hardware killswitches. It runs PureOS which is a linux distribution recently approved by FSF. They're still developing it so first batch of prototyping boards will be shipped June 2018, and first batch of complete phones will be shipped January 2019. You can learn more on their website:
