Xiaomi's Mi Mix 3 might be the first 5G phone ever

As mobile carriers light up their 5G networks, the race is on for phone makers to launch phones that can support faster data speeds.

While most manufacturers probably won't have 5G phones available until 2019 or 2020, China's Xiaomi   might release one by the end of this year, which would make it the first company to offer a 5G-ready smartphone.

Continuing with teases on social media for its upcoming Mi Mix 3, Donovan Sung, Director of Product Management at Xiaomi, tweeted a photo showing the phone being tested for 5G.
