Microsoft's FY2015 numbers for Q2 are just going up, and the numbers for Windows Phones are a bit complicated.
Revenue itself for Windows Phone is down a massive 61% from the last quarter. However, before we declare everything a failure for Microsoft, they explain away that number from the loss of $650 million from Nokia. The agreement had Nokia paying Microsoft per quarter, but that venture has since terminated. In other words, since Microsoft took over the Nokia mobile division, it can no longer collect that lump sum of money since they are now their own customer.
Interestingly, Lumia phone sales are up, both for year-over-year and sequentially from last quarter.
