The Mi Mix brand has been left to founder, with the last proper device, the Mi Mix 3, having been released over eighteen months ago. However, Xiaomi has registered a new Mi MIX Weibo account, hinting that it may not have long to wait until the announcement of a new Mi Mix. Could the Mi Mix 4 be almost upon us?

Buyers beware! The last Mi Mix flagship was the Mi Mix 3 5G and that hasn't received an update since! No Android or Miui latest releases. You would be better off with the cheaper phones!
