Today, Samsung is showing off SideSync, a new way for your Galaxy device and PC to work in tandem. Once you hook your Galaxy up to a PC with the software and app installed, your device then becomes an extension of the PC, allowing you to access certain device features from the PC and vice versa. For example, if you are working on a Word doc on the PC, then need to leave the Starbucks, you can simply drag and drop the file onto your phone and make your escape.
The app is available through the Samsung Apps app found on your Samsung device, so go check it out. As a reminder, you will need to have a Samsung account to download it, so make sure to get one of those.
