Google's Android platform has been growing steadily since its release in 2008. Now, one out of every three U.S. smartphone owners is using an Android-based device, according to a recent report.
 
So why aren't developers more excited about the platform?
 
Of the 69.5 million Americans who owned smartphones as of the end of February, 33 percent used Android devices, according to a report from ComScore. It's a leap of 7 points in a period of only three months.
 
The growth of Apple's iOS remained stagnant, seeing only a 0.2 percent increase over the same period of time. Competitors Microsoft, HP and RIM were the ones who suffered as Android grew, with drops of 1.3 percent, 1.1 percent and 4.6 percent, respectively. The five companies' smartphone market share is shown in the table below.
