Microsoft's Lumia 950 smartphone, the first to run Windows 10, has received mixed reviews. Computerworld's Preston Gralla noted it is only available from one carrier, AT&T, at $150 with a two-year contract, or $549 unlocked from Microsoft.
Gralla said the 950 comes with an excellent camera and allows for a replaceable battery, but has a cheap plastic case.
Llamas said that IDC's May forecast of 34% Windows Phone growth for 2015 was based on expectations that Microsoft would focus more heavily on Windows Phone improvements with its Windows 10 launch. But the main focus of Windows 10 has instead been on PCs and tablets.
IDC expects Android's share to move from 81% of the total global market this year to 82.6% in 2019. Apple's iOS will have 15.8% market share in 2015, IDC said, but drop to 14.1% by 2019, even though it will see a 6.5% annual growth rate in shipments, reaching 263 million in 2019.
IDC noted that the majority of Apple's sales have transitioned into replacement markets, which is a reason that Apple has moved into the iPhone trade-in space. A replacement market is one where a customer is replacing an existing phone instead of getting a phone or smartphone for the first time.
