Larger Galaxy S5
In some ways, the GTS is like a larger version of the Galaxy S5, and we could think of at least 10 reasons to like Samsung's latest smartphone. Though it's not waterproof like the GS5, it does include a fingerprint scanner for authenticating device access and transactions, a Kid's Mode that limits the available apps and UI functions in a friendly way and Knox, an iron-clad security tool that partitions user- and business-side files and apps. Samsung also boasts some tablet-industry firsts thanks to display technology it shares with its smartphone cousins. More on that later.
