Shortly after the Xiaomi device with model number M1908F1XE was received its 3C certification, China Unicom revealed a list of 5G phones available locally. This list includes a few handsets that have not been released yet and the Xiaomi Mi 9S is one of them. Sadly, we have no official confirmation of the fact that the M1908F1XE is the Mi 9S yet.

Yeah...If they properly update the NEX I could consider that along with LG and Asus too, preferably an international version so the firmware isn't the broken Chinese version...IQ00 is beyond consideration for their laughable naming.
