And over 1bn downloads from the Android Market each month.
Google's Android OS is seemingly going from strength to strength, securing 550,000 activations per day in summer 2011, which was up to 700,000 at the end of the year.
Now, Google's mobile SVP Andy Rubin says Android is receiving over 850,000 mobile activations each day.
It's an enormous leap in the space of two months, showing the speedy adoption rate of the operating system, given that it took half a year to achieve the same results in 2011.
Additionally, Rubin went on to reveal the Android Market has 450,000 apps, which up from 150,000 this time last year. The app store is also receiving more than one billion monthly downloads.
Last month, we reported that Google's mobile ad revenues are set to hit $4 billion this year, though it looks like that figure will be significantly beaten if Android can keep up its current pace.
