I've always liked cheap smartphones ($ 50) because with little money I can have a powerful system with lots of sensors and things like that. So I wondered if it was possible to use the hardware without using the very limited android APIs, programming it at a low level then, of course with the root. In particular I wanted to see how the LTE module worked and experiment with this having full control, the Android API does not allow it to do much.
UPDATE: I'm using something called libhybris, a wrapper that permit the use of android driver blobs in Linux.
