Nokia shipped 5.6 million Lumias in the first quarter, which represents a whopping 80% of the total 7 million Windows Phones that were shipped. The remaining 1.4 million is split between other OEMs HTC and Samsung. Huawei recently unveiled a Windows Phone 8 targeting prepaid consumers, but that was after the first quarter. All three of those manufacturers have a heavy focus on Android, so they have less to gain from Windows Phone’s rise. Google’s Android is very much the reason why Samsung is the top vendor in the world.
