Previously, Google would check the usage of different versions of Android via the times the device pinged Google’s servers, stating what software version it had. Starting this month, however, Google has included the actual visit(s) of devices to the Google Play Store, so that more versions can be recorded. Since this is meant to help developers building apps, it rather innocently boosts the stats of newer devices. Specifically, Jelly Bean (Android 4.1 or higher), up to 25 percent from 16.5 percent last month when it was calculated using the previous method. The number of devices recorded running Froyo and Gingerbread also took a bigt hit, down 3.6 and 4 percentage points, respectively.
It’s an interesting new way of calculating the way Android works and if it’s being introduced on better, higher-end devices.
