A few years ago, the Mobile operating system market could be regarded as "crowded", in addition to iOS and Android, there are blackberry, Samsung Tizen, Microsoft Windows Phone/Mobile, etc. However, today's pattern must be seen by everyone, stronger than Huawei Hongmon, there is still almost no presence in the overseas market.

According to media reports,Samsung permanently shut down the Tizen app store on Dec. 31, making it inaccessible to users of the phones involved.

In fact, in June last year, Samsung closed the door on new users signing up for its stores, limiting the ability to download only apps that had previously been used with an account, even for existing users.

The last Samsung phone to feature Tizen was the 2017 Samsung Z4. At one point in 2016, Tizen was the fourth largest mobile OS in the world, even more popular than blackberry.

Tizen is still used in Samsung's watches and TVS, but the project has been overshadowed by this year's Galaxy Watch 4, which announced Samsung's decision to abandon its own development in favor of Android Wear OS.

But Tizen is still the no. 1 TV system, thanks to Samsung's massive global shipments, and its future is unclear.
