Microsoft´s transition to Windows 10 Mobile results to be complicated and it seems the company is trying hard to deliver a convincing product. Market share of Windows Phone is down to just 1.7% according to Gartner figures for Q3 of 2015. In Q3 of 2014, Windows Phones still had a share of 3%.
International Data Corporation (IDC) predicts that Windows Phone / Windows 10 Mobile will not grow its market share until 2019. The prediction is based on Microsoft's lack of OEM partner support. In 4 years, Windows Phone´s market share is expected to only grow from 2.2% to 2.3%.
