YotaPhone vs GeeksPhone

The back screen writes information in E-Ink, meaning it can display that information without draining the battery. Apps can be set to route incoming information, from, for example, social networks, to that screen.

YotaPhone's signature feature is the dual-screen. On one side it has a typical capacitive 1080p display on the other an ePaper display. On latest generation phones both displays are fully touch compatible.

When buying a phone you typically buy into an OS, then only upgrade that OS to a new versions; never switch to a different OS. GeeksPhone was built to help open up the ecosystem, allowing for entry of other OSes without committing users to the investment & risk of getting a new phone with an OS with which they're not yet familiar.

To make this possible there are options to "install another OS" or "install zip from external SD" easily accessible from the phone.

GeeksPhone comes with a pre-rooted Android operating system that doesn't even includ the default Google apps.

FireFox OS, also known as Boot to Gecko or B2G, is a new operating system from Mozilla, that aims at creating an affordable smartphone solution for the emerging market.

To help Mozilla achieve this goal, GeeksPhone offers FireFox OS build as self-contained downloads for flashing the phone.
