The race for smartphone dominance is a little more competitive here in the U.S., though it still tilts in Android's favor. According to Kantar, Android finished 2013 with a 50.6 percent share of the smartphone market in the U.S., up from 46.2 percent the year prior, versus Apple's 43.9 percent share, down from 49.7 percent one year ago.

Lost in the shuffle of all this are some impressive gains by Microsoft's Windows Phone platform, which has seen its share of certain market territories more than double compared to a year ago. For example, Windows Phone is found on 11.4 percent of the smartphones sold in France, up from just 5 percent a year prior.
It's the exact opposite for BlackBerry, which saw its share decline in every single market Kantar reported on except for China, where BlackBerry is now installed on 0.1 percent all smartphones.
