It seems like only yesterday that Google bundled Ice Cream Sandwich 4.0 in its little biscuit layers and sent it off into the world (it was December, 2011, actually). That Android flavor has since climbed the charts rapidly, around four percent each month for the last while, and now occupies the ROM on 23.7 percent of robot-based devices -- up from 20.8 percent last month. That's in part due to new devices (like many in China) still coming out of the box with it, on top of older warhorses like the Samsung Galaxy Tab 8.9 finally grabbing some ICS. Meanwhile, its smooth-running younger sibling, Jelly Bean, made a slight gain to 1.8 percent of all Google-run slates and phones -- though that will likely change when the Galaxy Note II hits the market en masse and the Galaxy S III OTA 4.1.1 disseminates to all its owners. Meanwhile, Gingerbread still dominates Google OS installed devices at 55.8 percent, probably thanks to delays or denials of newer flavors to legacy devices.
