It took a while for Android Lollipop to even get its own slice on the OS pie chart Google releases regularly, but it now seems to be steadily gaining popularity. According to the latest Android stats collected from April 28th to May 4th, nine percent of devices are now running Lollipop. While that's still quite small, it's almost double last month's percentage (five percent). KitKat's stat slid down to 39.8 percent from last month's 41.4 percent, so a number of stragglers might have finally upgraded.
