Android now holds 53 percent of the market according to Millennial's smartphone mix, up 5 percent from the figures published in April.
As you were
As a result, iOS and BlackBerry which had both made gains on the market leader in recent months saw their respective shares fall back again.
Apple's hand is down 3 percentage points to 28 percent while RIM has fallen back 2 percentage points to 16 percent.
While it's essentially 'as you were' when it terms of pure market share, Millennial claims Apple is top dog when it comes to driving app revenue.
Appetite for Apple apps
In fact, iOS is by far the most lucrative platform for the development community as a whole.
Half of all app revenue in the US is made on Apple's platform, and Millennial claims that's a lead it's in the process of extending.
It's a market leading share that corresponds with Apple's position as the top mobile manufacturer across the US holding just shy of 33 percent of the market and iPhone's continued leadership as the most popular handset, accounting for more than 20 percent of all ad impressions.
