Huawei's Nova and Nova Plus: Slim and (somewhat) small

Both the Nova and Nova Plus have full-HD displays. The Nova, pictured here, is the smaller of the two at 5 inches.

Around back is the Nova's round fingerprint sensor for unlocking phone with just a touch. Above is the main camera lens and flash.

Both phones run Android Marshmallow on an octa-core processor.

The Nova's main camera has a 12-megapixel resolution.

Both phone also have USB Type-C ports on their bottom ends. To one side is the speaker.

The 5.5-inch Nova Plus is a bit bigger. But in an age where phones regularly push past 6 inches, it's hardly king-size.

The Nova Plus's back side also is rounded, but the camera lens has a different design and the fingerprint sensor is more of a square.

Indeed, it's best to turn the phones over if you want to tell them apart.

Like the Nova, the Nova Plus has no physical controls below the display.
