Until Samsung and Apple settle their differences regarding the thinnest device among the Galaxy S II and the iPhone, Huawei is stepping in at CES to unveil the world’s thinnest smartphone.

6.68 mm! Yes, thinner than seven millimeters is how thick the Huawei Ascend P1 S is. As for the specs, it’s also one of the fastest in its class. Check it out: 4.3-inch Super AMOLED display with qHD 960 x 540 resolution, dual-core Texas Instruments OMAP 4460 Cortext-A9 CPU clocking at 1.5 GHz and supported by the PowerVR SGX 540 GPU, and powering it all is Android 4.x Ice Cream Sandwich. There’s an eight-megapixel camera at the back with dual-LED flash and 1080p video recording capability plus a 1.3-megapixel HD front-facing which can record in 720p. There’s a 1,800 mAh battery to power everything.

If you come to think of it, even the thicker brother of the Ascend P1 S, the Ascend P1, is thinner than the Galaxy S II and the iPhone. It measures 7.69 mm and shares the specs of the P1 S. They both pack 1GB of RAM and 4GB of ROM but the P1 has a smaller battery of 1670 mAh.

Look for both smartphones in the second quarter of the year if you are living in Europe, Asia-Pacific, North America, Australia, Middle East or China. There will also be three color choices: metallic black, ceramic white, cherry-blossom pink.
