Samsung's Galaxy S10 lineup may have launched in March 2019, but the Galaxy S10, S10 Plus and S10E are still available and more affordable than ever. It may be tempting to get the newer Galaxy S20, but there's not much the S20 can do that the S10 can't. After unboxing your shiny new phone, there's a whole lot to learn about the device. For starters, they all run Android 10 with Samsung's latest One UI custom skin, which mixes Google's improvements with Samsung's. The update adds gesture-based navigation and better privacy controls, but there's so much more to learn.
