The Coolpad Catalyst is a disappointment. This phone may cost only $100, but it's not worth that much. The hardware is uninspired and looks cheap. The rough rear panel is questionable. The screen is simply awful. Data performance was sluggish. The camera is practically useless. Did I mention that the screen sucks? On the upside, battery life is decent. Moreover, phone call quality is one of the Catalyst's only redeeming features: voice calls are superb. It's nice to see stock Android, but Lollipop doesn't taste good any more.
