Last weekend, ZTE announced the Grand S II as the successor to its former flagship smartphone of 2013, however, the Chinese company neglected to inform us that a dual-SIM variant of the handset would also be produced, entitled, surprise, surprise, the Grand S II Dual.

As you’d expect, the Dual continues to pack similar specifications when compared to its single SIM brethren, sporting a 5.5-inch capacitive touchscreen with a resolution of 1080 x 1920 pixels, a Qualcomm Snapdragon 800 chipset powered by four 2.3GHz Krait 400 CPU’s, an Adreno 330 GPU, 2GB of RAM, 16GB of expandable internal storage, a 13-megapixel rear-facing camera with an independent LED flash and a 3,000 mAh non-removable Li-Ion battery.

Strangely, the S II Dual runs Android 4.2.2 Jelly Bean, while the regular Grand S II ships running the latest build of Android 4.3. But don’t despair, both handsets come with ZTE’s Mifavor user interface plastered over the top, which supposedly allows users to operate their phone with ‘little effort, naturally and easily.’

Typically dual-SIM smartphones aren’t overly popular in the United States, so we expect the S II Dual to be a Chinese and possibly European exclusive.

The Grand S II has lots of fancy software features under the hood, which are all demonstrated in the video below, including a new ‘always on’ voice recognition function that allows users to wake the device even when they’re on the other side of the room.
