The OnePlus 2 is an incremental step in terms of overall design language. The frame is a magnesium and aluminum alloy, which should keep weight in check, and provide a high-quality feel to the physical build of the device. On its left side is a new hardware feature called the “alert slider.” It’s a 3-stop sliding button allowing for quick switching between sound and notification profiles, making it easy to silence your phone in a hurry. The OnePlus 2 is a dual-SIM device, and it features a USB Type-C plug. The larger male USB plug is also reversible, and is patented by OnePlus. Switching out back plates is easier now with “StyleSwap” covers. OnePlus will have four new StyleSwap options available should you not prefer their signature Sandstone cover.
