The OnePlus 2 is a sequel to the company's first phone, the OnePlus One. It will come in three different versions, one with LTE support for the US market; a global version that will work in the UK, Australia and Asia; and one more for China.
The OnePlus 2 will retail for a bit more at $389 -- which converts to around £350 or AU$533 -- for the 64GB version. The 16GB model will only retail later in the year for $329.
The 13-megapixel rear camera also comes with dual-LED flash, an f/2.0 aperture and a larger sensor for low-light shots. It also has optical image stabilisation.
The Alert Slider is a new feature that lets you set how bothered you want to be. There are three modes: all notifications, priority notifications, and no notifications.
The OnePlus 2 will use a USB Type-C port, and buyers of the phone will never have to worry about which way is the right way to plug a USB cable in. There's also a fingerprint sensor.
