Speaking of the technology breakthroughs that Barra described as "black magic" at the event, Hadlee Simons, a South African tech reporter from local news portal africa.com, said, "The smartphone market is very competitive, vendors such as LG and Samsung have all brought eye-catching functions in their new phones that debuted at this year's MWC, and Mi 5 is definitely on that level."
