OREANDA-NEWS. June 08, 2016. Global smartphone sales will no longer hit double-digit growth, market researcher Gartner said Tuesday, while predicting a rise in sales of 7 percent for 2016. That compares with 14.4 percent annual growth in 2015 and the peak of 73 percent in 2010.

In terms of numbers, smartphone unit sales are predicted to hit 1.5 billion this year and inch up to 1.9 billion in 2020.

The market is suffering from a malady dubbed phone fatigue. Consumers are less willing to spend money on new phones due to a lack of sexy, must-have features. At the same time, mobile carriers have been killing off subsidized plans, forcing consumers to buy phones at full retail price and prompting them to hang on to their existing devices longer than in the past.

The wireless carriers and certain vendors such as Apple now push financing programs that offer people a new phone after just a year. However, those programs aren't catching on with all buyers.
