by all manufacturers in 2012. In 2012, all vendors combined shipped 677 million smartphones, but the estimate has Samsung and Apple combined shipping 800 million devices in 2018.According to Juniper, Android and iOS are expected to continue dominating the market. In fact, Juniper estimates that Samsung and Apple alone will ship more devices in 2018 than were shipped
But, Juniper also says that the market will continue to split, and by 2018 newcomers like Asha, Sailfish, Firefox, and Ubuntu will have taken over 13% of the market. Given that recently, all "others" beyond Android, iOS, and Windows Phone combined for only 3% of global shipments, that's a pretty big shift.
