Xiaomi was supposed to launch Mi mix 3's successor product, MI mix 4, but the company announced a leading smartphone, MI mix alpha, rather than mix 4. The giant later said it would not release Mi mix 4. However, the company did not mention whether it had completely shelved the MI mix portfolio to pave the way for MI mix alpha.Now, the latest leaks show that the company has not shelved the mix 4, and that smartphones are likely to go public next year.
