Google updated its Android distribution numbers this afternoon, showing a jump for Kit Kat from 17.9% in July to over 20% (20.9%) in August. While Kit Kat has climbed, the numbers show devices running Jelly Bean (54.2%) and Ice Cream Sandwich (10.6%) on the decline. Those running Gingerbread and Froyo haven’t moved much. Actually Android 2.3 saw a slight jump to 13.6% from 13.5%, which is odd.
