For the sake of discussion, let’s use $3 per device as our figure. This number is an estimate, but given all information in the market it’s our best guesstimate.
We can now do the math: 860 million Android devices in 2013, of which 65% pay Microsoft a fee, and that fee being $3 leaves Microsoft with $1.677 billion in Android revenue this year. That works out to just over $400 million per quarter, which fits with our earlier statements of Android patent revenue being in the low hundreds of millions.
The Next Web looks at just how much Android is making… for Microsoft.
