Samsung beats Apple to the remote-control punch with SideSync 3.0, a tool that attaches via Wi-Fi Direct to a nearby Samsung GS4 or GS5 phone (which also must be running the app) for answering calls, transferring files or performing other tasks remotely from the tablet. The remote phone's display is replicated in a floating window that's resizeable by dragging the lower-right corner and always on top. It can be made itty-bitty, minimized completely or scaled to full-screen mode. Buttons around its perimeter control maximize, minimize, rotate and quit functions; others replicate the remote device's home, recent and back keys. Remote functions, notifications and sounds operate regardless of window size. Touch sounds and haptic feedback don't carry over.
