Jelly Bean now on just about 50% of Android devices, Gingerbread keeps on ticking

It’s that time of the month where we find out how fragmented Android is. I guess the good news is that Jelly Bean has grown a lot faster than Ice Cream Sandwich did, which is a nice surprise. Jelly Bean is now on 48.6% of Android devices just 14 months after it was released. In contrast, Ice Cream Sandwich was only at 29.1% for the same timeframe. However, Gingerbread showed faster growth with a 58% share after the same 14 months. Granted, there wasn’t as many versions of Android at that time. Jelly Bean’s higher adoption rate is obviously due to the fact that a lot of newer phones came pre-loaded with it.
Gingerbread feels like Windows XP. It’s still on 28.6% of devices and doesn’t appear to be going anywhere soon. It only dropped about 2% from last month. The only way Gingerbread can shrink is when owners of those devices finally upgrade to newer hardware because the software will never get upgraded.
