"This year, we are looking to work even more closely with our customers worldwide to develop the products they want and deliver a superior customer experience. They have told us that they want ever more innovative and high-performance products, so at MWC 2014 we are delivering this with the launch of two new high-profile devices, the ultra slim Grand Memo II LTE with 6 inch screen and the ZTE Open C in partnership with Mozilla and Telefonica. We expect 2014 to be our strongest year yet – and we’re putting our customers at the heart of everything we do to help us achieve that."-Adam Zeng, CEO, ZTE Mobile Devices
ZTE is also expected to reveal version 2.3 of its MiFavor UI, which will appear on one or more Android handsets at MWC. Some interesting products include the ZTE Projector Hotspot, which combines a mini projector with a Wi-Fi hotspot, and the ZTE Grand Watch Smart Watch.
