Samsung is taking us back to 2014 - and that's a good thing.<br />The tech giant's newest flagship phone, the Galaxy S7, has brought back two things popular in 2014's Galaxy S5 but missing from last year's device: water resistance and expandable flash memory.<br />These may seem like minor additions to Samsung's all-important new phone, but surprisingly they're features that set the South Korean company apart from most of its big-name rivals.<br />The company remains the king of the mobile market, but it has seen its position waver over the past couple of years.<br />About 23 percent of all smartphones shipped last year came from Samsung, but that's down from 25 percent in 2014 and 31 percent in 2013, according to Gartner.<br />The new components are also what let Samsung bring back the microSD card slot.<br />The company has added a special SIM card slot, the part of the phone that holds a smart card with data about your device, that also works as a microSD holder.
