IDC says this quarter is the smallest year-over-year growth in smartphone shipments since smartphones were invented. This doesn't mean that shipments are going down - not exactly, anyway. Vendors shipped 334.9 million smartphones worldwide in the first quarter of 2016 (1Q16). This is slightly more than what they shipped this same time one year ago - 334.3 million units. Less than a million unit shipments difference year-over-year. That is, indeed, unprecedented. It would seem that everyone already has a smartphone. Everyone that would have bought one in the last three months otherwise, anyway.
