One-handed use: if you have a device with a screen of 5 inches or greater, it's now easier to use your device with one hand. Press and hold the Start button and your screen will slide down so you can reach items at the top of your screen. To slide the screen back up, tap the black space at the top of the screen, or press and hold the Start button again. One-handed use will also naturally time out after several seconds and return to your regular view.
