The watch is available in one size (44mm) with bands in either black or blue. It also works with any 20mm watch bands. Like the Galaxy Watch and Gear S3, the Gear Sport Watch has a rotating bezel for navigation. It also has an accelerometer, ambient light sensor, barometer, heart rate monitor, and gyroscope. The watch runs on Samsung’s Tizen OS, not Google’s Wear operating system, and it’s compatible with Samsung smartphones, Android phones running Android 4.4 and later with at least 1.5GB RAM, and the iPhone 5 or later with iOS 9.0 and above. These are the five best Samsung Gear Sport watch features. The watch also has a Gear for Nest app so you can adjust your home’s temperature and other Nest thermostat settings by rotating the watch bezel. Swipe down the Status panel on the watch, tap Water lock mode > Done. To turn off Water lock mode, press and hold the Home button. Lightly shake your watch whenever your watch gets wet to remove any water. You need the PowerPoint app on both devices. Launch it on your Gear Sport and tap Connect; it should then appear in the list of nearby Bluetooth devices on your computer. Once connected, tap Slideshow. Tap to move the next page or rotate the bezel clockwise to advance and counterclockwise to return to a previous slide. Tap Touchpad to control the cursor on the computer and tap Stop to end the presentation.
