Even though most smartphones today run on Android or Apple's iOS operating systems, there are still a bunch of other players scrambling to fill in the gap for third place.
One of those is called Tizen, an open source operating system that's being developed by Samsung and a bunch of other companies.
Some see Samsung's involvement in Tizen as a sign that it's trying to ween itself off Google for smartphone apps and services. Samsung misses out on a lot of potential revenue when Galaxy phone owners use Google services like Gmail and buy apps and content from the Google Play Android store.
In fact, Samsung already announced a major Tizen-powered device this week at the Mobile World Congress in Barcelona, the new Gear 2 and Gear 2 Neo smart watches. (The original Galaxy Gear ran Android.)
It makes sense too. Samsung is the biggest Android phone maker, and the only company that makes any real profit from Android phones and tablets. If it suddenly decides to migrate to Tizen, then Google will lose its biggest Android partner and a bunch of potential revenue and market share.
Tizen is still in its early stages and likely won't start shipping on devices for another year or more. But we got a look at an early version running on a prototype Samsung device.
