Just like that, the companies behind every major smartphone operating system now compete directly with their manufacturing partners. And while Google erected a "firewall" between Android and Motorola when it bought the handset maker in 2012, Microsoft has no plans to separate Nokia from the core Windows Phone business. It's full steam ahead for Microsoft-made smartphones as Redmond tries to single-handedly turn Windows Phone from an also-ran into a contender.
The sudden circling of the in-house wagons has to have third-party handset makers like Samsung, HTC, and LG sweating.
"Vendors who are not tightly aligned with an operating system company…[have]…got to be looking at this and saying 'Maybe I should be looking a little more closely at how to chart my future by partnering or owning my own operating system stack,'" says Ramon Llamas, a research manager with IDC's mobile phone team.
