In the fourth quarter of 2011, Motorola unveiled the Droid RAZR, the world's thinnest 4G LTE smartphone at that time at just 7.1 mm. The Droid Razr featured Kevlar backing, the same used in bulletproof vests, and a Gorilla Glass faceplate. The phone was very successful through Verizon Wireless, and many color variants were released. In addition, a Maxx version of the Droid RAZR with an extended battery was released at CES 2012. The Droid RAZR MAXX won CTIA's "Best Smartphone" award. The company also announced new products by late 2011 and early 2012 such as the Xoom 2 tablets, the motoACTV fitness watch with Android, and the Droid 4 with 4G LTE for Verizon Wireless.
