What a difference a month makes. Less than 30 days ago, Google reported there were finally more devices in active use running Android 4.0 and up than devices running the Android 2.3 operating system (code named Gingerbread).
The vast majority of those Android 4.0 users, however, were using Ice Cream Sandwich and not the various flavors of the newer Jelly Bean (Android 4.1 and 4.2).
Now, Google's Android developer site reports a jump of almost nine percentage points for Jelly Bean devices (counting both versions 4.1 and 4.2) from 16.5 percent of all Android users in early March to 25 percent in early April. According to Google's numbers, the majority of Jelly Bean devices run version 4.1 and not 4.2, which was released in February.
That's a massive jump in just a few weeks. Unless thousands of users suddenly upgraded their devices or went out and purchased new phones , something is rotten in the city of Mountain View.
How Google counted
To see that big jump in Android 4.1 and 4.1 usage, Google modified how it was counting Android users. Previously, Google simply counted the number of unique devices that pinged the Google Play Store, whether as an automatic device setting or a user-initiated visit.
Now, however, Google only counts Android users based on user-initiated visits to the Play Store. "We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem," Google said on its developer page when announcing the change.
Google's change in how it counts Android devices sounds like a better metric for developers since it focuses on those who are actively engaged with the Play Store and most likely to download apps. But it's not so great if you're trying to get an idea of how many active Android devices are out there, regardless of whether they use the Play Store or not.
Users with older devices, for example, may give up on downloading apps from the Play Store altogether. This could be for a variety of reasons, such as full device memory or poor performance of newer apps on older devices.
Then there's the various Android users in markets such as China, who may not use the Play Store at all. And a smaller stable of users may be using carrier-specific app stores or alternatives to the Play Store such as Getjar.
Google's new metric may also skew towards early adopters who always have the latest and greatest version of Android and would, by definition, be some of the most active Google Play users.
Google's numbers also don't necessarily reflect an increase in actual Jelly Bean users. For all we know, Google's new statistics significantly reduced the number of devices counted overall.
