Rinato (Samsung Gear 2) is a Tizen-based smartwatch released in 2014. See gsmarena for detailed specs. There are two variants of this watch - Gear 2 (SM-R380) and Gear 2 Neo (SM-R381), which are identical save for a camera that's only present on the Gear 2.

As the vendor kernel is very old (3.4) and there's no existing abstraction for the Tizen HAL, a mainline Linux port for this watch is being attempted instead.

Downstream sources available at https://github.com/casept/linux-exynos3250-common/tree/rinato, as Samsung no longer hosts them.

Hardware docs and kernel support

Current port state

This watch is being worked on here.

Currently (June 2024) the watch boots and the launcher starts, but rendering is extremely sluggish. This is suspected to be caused by lacking support for non-Android hardware acceleration in Asteroid's version of lipstick, and is currently being investigated.
