Another day, another player stepping into the 5-inch smartphone arena. As listed on CES 2013 official website, ZTE will be unveiling its 5-inch full HD display flagship option, the ZTE Grand S, on January 8th at the major consumer electronics trade show. Aside from a 5-inch form factor, the Grand S is touted to be the "world's thinnest", and features" a traditional Chinese style" on its ceramic body. There's also reason to believe that it is related to the previously leaked Nubia Z5 model:
PhoneArena - "There is some speculation that the ZTE Grand S is related to the ZTE Nubia Z5 model that we have been seeing much of lately. The ZTE Nubia Z5 is expected to be equipped with a 5 inch display offering 1080p resolution, and a quad-core Qualcomm Snapdragon S4 Pro under the hood. 2GB of RAM and a 13MP rear-facing shooter continue the high-end specs parade for the unit. The device is said to be just 7.6mm thick. All of it dovetails with what we know about the ZTE Grand S."
