Xiaomi unveiled its latest foldable phone Monday, as part of an annual event that saw CEO Lei Jun take the stage. The Mix Fold 3 is a book-style foldable phone designed to compete with Samsung's Galaxy Z Fold 5, except it will not be available globally. As usual, Xiaomi is releasing it only in China, where it will start at 8,999 yuan, which converts to approximately $1,240, £980 or AU$1,920.
