Microsoft mobile revenue continues to grow, though for the time being it seems as though the bulk of it is coming from Android. Goldman Sachs analysts on Thursday estimated that the software company will pull in approximately $444 million in fiscal 2012 from licensing deals made with various Android vendors such as HTC and Samsung, based on royalties of $3-$6 per Android device sold. Asymco’s Horace Dediu estimated in August that Microsoft took in approximately $21 million in revenue from Windows Phone licenses in the second quarter, and he believes the company earned roughly $60 million from Android royalties over the same period from HTC alone. With Samsung now paying Microsoft royalties along with HTC, Acer and other Android device vendors, Goldman Sachs’ estimate certainly seems feasible.
