Android Central

According to the IDC, Android accounts for 59% of all smartphone sales worldwide.  This is a healthy jump from last year when Android accounted for 36.1% of smartphone sales.  iOS is second, with 23% of sales.  Last year the two smartphone OS's owned 54.4% of the market combined, ​so this is impressive growth.  Android showed a 145% year-over-year change, at the expense of Symbian, which went from 26% in 1Q11 to just 6.8% in 1Q12.

Samsung is the big winner here, accounting for 45.4% of all Android smartphone sales.  This is due in no small part to the success of the Galaxy S II and Galaxy Note, both of which have racked up impressive sales numbers.  With the looming launch of the Galaxy S III Samsung is showing no signs of slowing down, either.
