postmarketOS - A Real Linux Distribution for Phones
postmarketOS is a free and open-source operating system under development primarily for smartphones, based on the Alpine Linux distribution. PostmarketOS was launched on May 6, 2017 with the source code available on GitLab.
postmarketOS guys are sick of not receiving updates shortly after buying new phones. Sick of the walled gardens deeply integrated into Android and iOS. That's why they are developing a sustainable, privacy and security focused free software mobile OS that is modeled after traditional Linux distributions. With privilege separation in mind.
Let's keep our devices useful and safe until they physically break!
Because postmarketOS is completelly opensource it can be ported! Here is a list of postmarketOS ports to various devices.
PinePhone is an open source smart phone supported by all major linux phone projects. The purpose of the PinePhone isn’t only to deliver a functioning Linux phone to end-users, but also to actively create a market for such a device, as well as to support existing and well established Linux-on-Phone projects.
