As it does every month, Google has just updated the Android distribution data to reflect the month of July. Jelly Bean is now running on 37.9 percent of devices, with 32.3 percent of those running Android 4.1.x. That’s up from 33 percent this time last month. Gingerbread fell from 36.5 percent to 34.1 percent, which makes Jelly Bean the most used Android operating system. Ice Cream Sandwich is now at 23.3 percent, down from 25.6 percent last month.
Froyo is now at 3.1 percent (was at 3.2 percent), Eclair has fallen to 1.4 percent (was at 1.5 percent), Honeycomb and Donut are both now at just 0.1 percent.
Google collects this data during the first week of each month by logging the devices that access the Play Store. It use to be that the data was collected when the device simply checked-in to Google servers.
