I've been using Android 4.x Jelly Bean since day one, and I'm in love with it. But, it has seen a slow adoption rate, but thanks great selling smartphones like the Galaxy S4, HTC One and Xperia Z, Jelly Bean has finally become the dominant version of Android.
The numbers speak for themselves, with the digits posted on the Android Developers website. As it stands right now, Android 4.1 and 4.1 are found on 40.5% of all Android devices, up from 38% of devices last month. This news means that Android 2.3 "Gingerbread" users are upgrading, with Android 2.3 numbers down to 33%, just 1% lower than June's numbers of 34%.
