Google likely makes well over $10 billion a year from Android. Only when comparing against iPhone revenue or Google's own advertising revenue does it look small.
Thanks to a lawyer, we know now that Google has made $31 billion in revenue and $22 billion in profit from its Android operating system....
That’s over Android’s entire existence.
But if the $31 billion total is correct, Google has earned less money from Android throughout its existence than Apple earned from iPhone sales in fourth quarter of 2015, when it brought in $32.2 billion in revenue.
