A $50 open source smartphone based on the Raspberry Pi Zero
This project is launching soon.
ZeroPhone is an open source, Linux-powered, $50 smartphone. It has no
carrier locks, bloated apps, or data mining, and it doesn’t depend on
big companies - instead, its open source hardware and software give
you as much control over your phone as possible.
ZeroPhone is user-friendly and will have the typical features of a
phone, but will give you advanced features when you need them. You can
modify and repair it easily, and it’s power-user and
programmer-friendly. It’s also built from widely available components,
so you can build a ZeroPhone independently if you need to.
