hey frnzz...we all know now kitkat is the best n present latest os From Android ....so lets see the stats of all versions once !
KitKat has risen from 1.8% to 2.5% of Android devices—a increase rise of just under 40%. Jelly Bean has risen as well, albeit at a significantly slower pace, from 60.7% to 62.5%. Ice Cream Sandwich is down to 15.2% from 16.1% last month, and 2.x is down to just 20.2% from 21.3% last month. And since the total percentage of devices running 4.x is relatively unchanged at 79.9% from 78.6%, it’s not unreasonable to assume that most of the increase in KitKat and Jelly Bean has come at the expense of Ice Cream Sandwich...
