The seemingly unstoppable Xiaomi just had a pretty rough year, having failed to achieve even the lowest sales goal that it set for itself, thanks to intense competition from Apple and its fellow Chinese smartphone makers. Huawei and Lenovo were especially aggressive last year, but there’s another company that always manages to get overlooked, even though it managed to sell more than 50 million smartphones last year. That company is called Oppo, and its smartphones sales have been exploding over the past couple of years, to the point where it’s close to surpassing LG to become the world’s sixth-largest smartphone maker. Once it does that, it’ll be on its way to surpassing Xiaomi and Lenovo to secure the fifth and fourth spots in the smartphone market, respectively.
