When it comes to hardware design language, non-Apple/-Samsung phones tend to be all over the place, even within the same product line. One model of a phone may use onscreen soft buttons, the next one may have hard physical buttons. One year's phone may be made of metal with fingerprint sensor on the back, the next it might be leather with a front scanner. Meizu, on the other hand, has stuck with the same design language over at least a half dozen phones released in the past two to three years. The result has been mostly good -- Meizu's phones are very nicely built metal unibody devices with a sturdy oval all-in-one home button that doubles as a fast fingerprint sensor.
