Android platform versions

The latest numbers are in, and things are continuing to move in the right direction: The "Jelly Bean" version of Android -- that's Android 4.1 and 4.2 -- is now on 10.2 percent of all active devices, as of the two weeks ending Jan. 3. For the two weeks ending Dec. 3, 2012, Jelly Bean was on 6.7 percent of all active devices. Ice Cream Sandwich numbers were up slightly as well, from 27.5 percent to 29.1 percent. Devices on Android 2.3 Gingerbread are trending down, from 50.8 percent last month to 47.6 percent today.

Breaking down the numbers, you'll see that both Android 4.1 and 4.2 increased about 50 percent over last month. But It's Android 4.2 that's on more phones and tablets -- thanks in no small part to updates to the Samsung Galaxy S3, HTC One X and One S, and Motorola's RAZR line. Android 4.2 means Nexus, of course (and custom ROMs), and remains significantly lower.
