Unveiled at thePT/EXPO COMM CHINA 2012, the Grand Era contains a "PC-class" Nvidia Tegra 3 quad-core CPU and operates on Android 4.0 Ice Cream Sandwich.
It has a 4.5-inch HD retinal screen boasting a resolution of 1280x720, along with an 8MP BSI AF HD camera. All this comes in a form factor that has an average thickness of 8.6mm, and is just 7.9mm at the slimmest section.
ZTE believes that this is currently the thinnest form available for any quad-core handset. The Huawei Ascend P1 is slimmer, at only 6.68mm thick, but it comes with just a dual-core processor.
Following various headlines about cyber criminals and device security, ZTE has fitted the Grand Era with a new tool called Palm Manager.
Independently developed by ZTE, this dual software and hardware system monitors permissions for installed applications protests user information in relation to power management, traffic monitoring, software and security protection.
"The Grand Era has opened the door to the quad-core era for ZTE smart phones," said ZTE executive vice president He Shiyou.
"We believe these products will produce a butterfly effect across the industry, domestically and abroad."
ZTE has also announced additional models at the expo, including the Grand Era V985 and the Grand Era LTE.
The handsets will launch in China in the "coming days" , but there has been no indication as yet whether the range will arrive in other markets, such as the UK.
