Xiaomi has announced the newest version of its bezel-less Mi Mix family, and it doesn’t sport a notch like its Mi 8 flagship. Indeed, unlike the Mi 8 — which I called one of Xiaomi’s most brazen Apple clones — there’s a lot more to get excited about.

The Mi Mix 3 was unveiled at an event in Beijing and, like its predecessor, Xiaomi boasts that it offers a full front screen. Rather than opting for the near-industry standard notch, Xiaomi has developed a slider that houses its front-facing camera. Vivo and Oppo have done similar using a motorized approach, but Xiaomi’s is magnetic while it can also be programmed for functions such as answering calls.
