the Past few years, a monthly report from Google about the percentage of used versions of the OS, Android 2.2 Froyo invariably in the list of operating systems, even showed a slight indicators. However, in January 2017 this version of the OS from Google was excluded from this list.
of Course, this does not mean that devices running this OS not left. However, their number is so small, that there can be any meaningful for General statistics.
the oldest of the remaining in the list of versions is Android 2.3 Gingerbread, under which at the moment still has about 1% of Android gadgets, so it is not surprising if this version of the next will drop off the list.
Android 7.0 Nougat showed in the last month, an increase from 0.4% to 0.7% of all devices running Android. The 1 percent in the us, but expect that it will happen soon. It is noteworthy that the increase in the percentage received not only the latest version of the OS, but also Android 6.0 Marshmallow, the number of gadgets under which increased from 26.3 to 29.6%.
Other versions of Android such as Lollipop, KitKat, Jelly Bean, Ice Cream Sandwich, and Gingerbread showed a decrease in percentage. I hope that February, thanks to the active update OS many manufacturers will allow Nougat to exceed 1%.
