ZTE doesn’t have a strong presence here in the U.S., but the vendor revealed several smartphones at this year’s Mobile World Congress trade show that will be big sellers in a number of markets. The Era, Orbit and PF112 are among the new ZTE phones that will launch this year, and we spent some time with each of them on Monday. The Era and the PF112 both run Google’s Android 4.0 Ice Cream Sandwich operating system, while the Orbit is a Windows Phone. The Era is a quad-core Tegra 3-powered beast with a 4.3-inch screen and high-end specs that rival any device launched here at the show. The PF112 sports an even larger 4.5-inch screen, tri-band HSPA+ and an 8-megapixel shooter. The Orbit is the company’s low-end Windows Phone model, with a 4-inch display, a 1GHz processor and 4GB of on-board storage. In use, the Windows Phone-powered Orbit was definitely impressive for an entry-level smartphone, exhibiting the smooth user experience we’ve come to expect from handsets powered by Microsoft’s mobile platform. The Android phones weren’t operational, so we can’t comment on their performance. We can definitely still admire their sleek designs though, so check out our hands-on gallery for photos of each of these new ZTE phones.
