Chinese smartphone maker ZTE showed off its high-end flagship device, the Grand S II, at the CES 2014, highlighting its powerful processor, vibrant display, responsive voice-assist technology and a lot more.

ZTE, the Chinese smartphone making company, has unveiled its powerful flagship smartphone at the year's most promising electronics show, the CES 2014. The new smartphone, Grand S II, features high-end specs seen in any flagship models from different leading manufacturers. The phone company has already made quite an impact at the event by showing off its first and the world's second modular phone concept in its Eco-Mobius model. Now, the company is bringing more heat in the competitive smartphone industry with its powerful Grand S II.

The new Android-based ZTE smartphone features a 5.5-inch 1080p Full HD display and the latest 2.3GHz quad-core Snapdragon 800 processor, like the one in Samsung Galaxy Note 3. To aid the powerful chip, ZTE throws in a 2GB RAM and 16 GB internal storage, expandable up to 32 GB via microSD card. It sports a 13-megapixel rear-facing camera and a 2-megapixel front shooter and a huge 3,000 mAh battery.

ZTE Grand S II runs on Google's Android 4.3 Jelly Bean, but there is no information on the 4.4 update for the smartphone. The phone uses ZTE's custom-user interface, which in turn adds some extra features, like split-screen multitasking, glove mode for the touch screen, and a few motion gestures, CNET reports.

ZTE has introduced its own voice-assist function for the Grand S II, which responds to "Hello ZTE" in the same way Motorola Moto X responds to its voice functions. On the downside, the device only understands Chinese, which coincides with the company's plans to limit the phone sales to China. The Grand S II will make its debut in the U.S. market, but not until the later part of this year when the phone will be incorporated with other languages.

The pricing of the device currently remains unavailable, but the CNET report says the phone was sold online for $399.99 unsubsidized. The price range will likely differ if it makes it to the U.S. market.
