At its I/O conference Wednesday, Google announced that there are currently 1 billion active Android users globally.

In the 30 days prior to the conference, the number of Android smartphone and tablet users grew some 86% compared to the same period a year earlier. In June of last year, Google had just 538 million 30-day active Android users.

And one year earlier, between 2012 and 2013, the number of active Android users more than doubled, growing 140%. There were only 223 million active Android users in June 2012.

Based on this growth, BII estimates that as of this month, there have been about 1.6 billion cumulative Android activations. Google has not reported a cumulative activations number since September 2013, when Android eclipsed the 1 billion activations milestone.

Apple, by comparison, recently announced having sold “well over” 800 million iOS devices to date, though it didn’t reveal how many monthly active iOS users there are.

Google also revealed a couple other eye-popping stats for the platform, including that Android users send 20 billion texts per day and 93 million selfies.
