Use the Touchscreen
Your phone’s touchscreen lets you control actions through a variety of touch gestures.
When you want to type using the keyboard, select items such as application and settings icons, or press buttons, simply tap or touch them with your finger.
To open the available options for an item (for example, a contact or link in a Web page), touch and hold the item.
To swipe or slide means to quickly drag your finger vertically or horizontally across the screen.
To drag, press and hold your finger with some pressure before you start to move your finger. While dragging, do not release your finger until you have reached the target position.
Flicking the screen is similar to swiping, except that you need to swipe your finger in light, quick strokes. This finger gesture is always in a vertical direction, such as when flicking the contacts or message list.
For most screens, you can automatically change the screen orientation from portrait to landscape by turning the phone sideways. When entering text, you can turn the phone sideways to bring up a bigger keyboard. See Samsung Keyboard for more details.
Note: Auto rotate needs to be enabled for the screen orientation to automatically change. Pull down the status bar to display the notification panel, and then tap Auto rotate to enable the option.
