Android stood at the core of Samsung’s rise to dominance in the global smartphone market, and Google’s mobile OS continues to power a vast Samsung Galaxy family of smartphones. Despite what seems like the perfect love story, however, Samsung is doing its best to separate its future from Android by slowly adopting Tizen, an open-source OS that Samsung is developing with help from other companies such as Intel, Huawei, Vodafone, and Sprint.

One segment where Samsung has aggressively pushed Tizen as an Android alternative are smartwatches. Out of the seven watches that Samsung has launched so far, only one of them – the Samsung Galaxy Gear – came with Android Wear. The rest of them, including the recently-unveiled Gear S2, run Tizen.

As far as Samsung’s smartphone efforts are concerned, Tizen powers a single smartphone, the Z1. Given the entry-level philosophy behind the Samsung Z1, a very cheap handset aimed at emerging markets around Asia, no one was deeply surprised to learn that the Tizen-based Z1 lacks compatibility with Samsung’s Tizen watches. But with the upcoming Samsung Gear Z3, the company appears to have bigger goals in mind.
