From Apple’s and Google’s Q2 quarterly earnings call, respectively.
Google just announced that they activate 550,000 Android devices per day. That’s in all likelihood (and considering the language) not an average value for the whole quarter but only the most recent value (that must have been rapidly growing during the last quarter). Still, the average for the last quarter is probably over or around 500,000.
Apple doesn’t publish any such numbers but it’s easy to estimate them. Apple sold 20m iPhones, 9m iPads and 8m iPods. Tim Cook said during the earnings call that about half of those iPods run iOS. That’s about 33m iOS devices altogether for the whole quarter, for an average of 360,000 sold devices per day.
