The days of the $700 Android smartphone are numbered.

Exhibit A is the $400 OnePlus 3, the latest in a string of value smartphones from a Chinese startup challenging the full-priced giants.

Apple Inc. may have a little more time in the premium-price range, given that purchasing an Apple device gets you services such as iMessage and Apple Photos you otherwise can’t use. But when it comes to Android devices, the OnePlus 3 puts even Samsung Electronics Co. ’s killer Galaxy S7 on notice.

First, the OnePlus 3 has a great metal-and-glass design. Sure, it may look a tad too much like an iPhone. (And have the same lack of expandable storage and removable battery.) But it’s one of the sharper-looking phones out there.

It’s also future proof. The design includes the new USB Type-C port, which is growing in popularity for its ability to carry plenty of power and data, and send power in two directions. (It’s also nice because there’s no up or down—any way you plug it in, it fits.) With 6 gigabytes of RAM and the brand-new Qualcomm Snapdragon 820 processor that’s found in many $700-and-up competitors, it won’t be obsolete the morning after you buy it.
