The top OnePlus phones show that there are alternatives to Apple and Samsung's duopoly when it comes to smartphone purchases. OnePlus has evolved from obscurity to a smartphone manufacturer capable of competing with the best in less than a decade. OnePlus achieves this by putting as many quality features as possible onto their phones while yet keeping prices lower than similar Apple and Samsung smartphones. As the price of OnePlus flagships has risen in recent years, the company has shifted its focus, creating the Nord budget line, which still manages to put a few top features into low-cost devices.
