OnePlus started as an underdog offshoot of Oppo, one of the largest phone manufacturers in China. It provided smartphone enthusiasts with powerful hardware, fast software, and great values, making it the phone of choice for many. These days, OnePlus has a complete line of phones, from its well-regarded Nord line of budget and mid-range models up to its top tier OnePlus flagships. Though it has lost some appeal among enthusiasts due to changes in its software design and the ever-increasing prices of its high-end models, OnePlus is still one to keep an eye on.
