샤오미가 MIUI의 이름을 하이퍼OS로 바꿨는데요.

MIUI 15부터 중국 지역에는 하이퍼OS라는 이름으로 출시되지만 다른 국가/지역에선 계속해서 MIUI라는 이름을 사용합니다

At first, Xiaomi was planning to use the name MIUI 15, and the official MIUI server already confirmed this. The ‘Bigversion’ section indicates it as 15, which signifies the MIUI version. ‘[Bigversion] => 15’ stands for MIUI 15. However, for some reason, a decision was made to change the name. Today, Wang Hua stated that names like MiOS, CNMiOS, and MinaOS are entirely incorrect.
