According to the ranking of brand sales in the first half of 2016 calculated by the market research company, the overall sales volume of the domestic smartphone market in the first half of 2016 reached 250 million units, of which Huawei ranked first with 43.77 million units, OPPO and vivo ranked second and fourth, Apple firmly occupied second place, and Xiaomi, once the hegemon, ranked fifth. The sales volume of its 23.65 million units is nearly 20 million less than that of Huawei, which ranks first. It seems that Xiaomi really needs to focus on returning to the mobile phone market first. After all, if it loses in the main battlefield, the pyramid that has been built with difficulty will be equal to less than the foundation.
