Gartner’s latest report shows that the revival of the smartphone market began during the first quarter of 2018 after the first ever setback. During the first three months of 2018, smartphone sales increased 1.3 percent year-on-year to 383 million, which represents 84 percent of the total 455 million smartphone shipments.

The high-end market segment was affected because of the lower rates of an upgrade, while better quality affordable smartphones pumped growth in the mid-range market. Demand for high-end smartphones remained low because consumers weren’t lured by the marginal incremental benefits.
