A few years ago, the mobile operating system market could be called a "race for the buck". 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. It is better than Huawei Hongmeng, and it is still almost blank in the overseas market. According to media reports, Samsung has permanently closed the tizen app store on December 31 last year, and relevant mobile phone users have been unable to access it. In fact, in June last year, Samsung closed the store and registered new users. Even for existing users, it also limited the function, that is, it can only download the programs previously recorded by the account. It is reported that Samsung's last mobile phone equipped with tizen system is the Samsung Z4 in 2017. In 2016, tizen was once the world's fourth largest mobile OS, even more popular than BlackBerry. At present, tizen is also used in Samsung's watches and TV products, but this year's Galaxy watch 4 announced that Samsung gave up self-development and turned to Android wear OS. The tizen project has been a shadow. However, due to the huge global shipments of Samsung TV, tizen is still the largest TV system, and it is unknown where to go in the future. (Xinhua News Agency)
