So market share and sales have nothing to do with each other?
Not exactly. I mean globally Nokia and RIM both have massive marketshares counting everything they do BB7/BB10 and Symbian/Windows Phone. Yet that Marketshare doesn't matter that much since most of it is in emerging markets and places that can't afford the high end money maker devices that makes the headlines.
These markets will make sure that RIM and Nokia will never fully disappear but they won't be playing on the samsung/Apple level unless the high end Blackberry and Lumia devices start to make major waves.
Also like Insanolord said just because Android has a high market share doesn't automatically mean sales. Right now the only ones making money off of android from a hardware standpoint are Samsung. HTC and Sony are respective #2 and #3 and both are considered struggling in the hardware space. Its mostly because HTC doesn't know how to market and no american carrier wants to play ball with Sony.
Even Google is having trouble despite the nexus line selling decently enough since the Galaxy Nexus. There have been reports about Google being worried Samsung possibly forking Android in favor of going with their own services.
Here's a Verge link since the actual WSJ article is behind a pay wall.

The only way Google is going to gain any sembablance of hardware control over at Google (if they care anymore) would be to play ball with carriers something that Google doesn't want to do after the Verizon-Galaxy Nexus debacle. I can see them continuing their T-mobile partnership since tmo is going all in getting rid of contracts as they're main method of payments. It probably won't happen anytime soon but after seeing the Chromebook Pixl I really want to what an intenrally made android device from google would be like.
