This page is about developing hardware for Jolla devices.

The Other Half development

Jolla Phone (2026) features The Other Half (TOH) functionality. TOHs are back covers that can interact with the phone software. This is enabled via pogo pins on the back of the device that provide power, charging input, I²C / I3C communication and interrupt. The device also features mounting points intended for heavier versions of TOH but most are expected to just clip on.
