Android Jelly Bean got a boost over the last two weeks, according to developer stats from Google, thanks in part to the search giant revising the way it calculates activations.
As of 2 April, Jelly Bean was on 25 per cent of Android devices, with 23 per cent running Android 4.1 and 2 percent running Android 4.2. That's up from 16.5 per cent in March.
Why the large jump? Google noted that starting this month, its Android platform version charts will be based on data collected from each device when the user visits the Google Play Store rather than when the device checks in to Google servers.
"We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem," Google said.
"Note that as a result of these adjustments, some slices of the pie charts have changed more than usual," Google said on Google+.
The new data shows that Jelly Bean is gaining on its predecessor, Ice Cream Sandwich, which is now on 29.3 per cent of Android devices, about the same as last month. Both systems continue to lag behind the aging Gingerbread operating system, which is still on 39.8 per cent of devices — a drop from last month's 44.1 per cent.
Meanwhile, Android 2.2 Froyo still powers 4 per cent of Android handsets, more than Eclair (1.7 per cent) and the very early Donut (0.1 per cent).
Jelly Bean will likely get a boost from the upcoming launch of Samsung's Galaxy S4; it has already been pushed out to the Nexus 7 and Nexus 10 tablets, as well as the Nexus 4 and Galaxy Nexus smartphones.
