Device Atlas, the world’s most authoritative source on device data, states that there were 2.6 billion smartphones and over 4 billion mobile phone users in the world in 2016. This number is expected to double over the next few years. These devices are attached to us 24 hours a day, seven days a week. They have replaced our computer and camera, allow us to scan barcodes to check prices and act as a credit card. They help us email co-workers, message friends, and can, surprisingly, even make phone calls!
With so many devices performing mission critical functions . . .
