Change the Gear S2’s App Shortcuts Widget Apps
To add the App Shortcuts widget in the watch screen, swipe from right to left on the screen repeatedly (or rotate the bezel to the right) until you see the Add Widget screen.
You can’t miss the Add widget icon on the screen.
Tap the Add Widget icon. Swipe from right to left once, or rotate the bezel to the right until you feel a click.
The App Shortcuts widget image appears in the center of the screen. Tap the widget image to add the widget to your Gear S2. The widget title appears at the bottom of the screen. You can use the App Shortcuts widget when it appears on the screen.
But to edit the widget, you need to tap and hold the center of the screen (in the blank spot between all four icons) for a couple of seconds until you feel the Gear S2 vibrate.
Then the Edit screen appears. The Edit icon appears at the bottom of the Edit screen.
Start making changes by tapping the Edit icon.
Each of the four icons includes a Delete icon in the upper-right area. The Delete icons are red minus signs inside white circles.
To remove an app, tap the Delete icon in the upper-right corner of the app icon.
The icon disappears and an Add icon appears. The Add icon is a plus sign inside a circle.
Tap the Add icon to view the list of apps you can add.
The currently selected app icon and name appear in the center of the screen. Swipe right and left on the screen, or rotate the bezel right and left, to scroll through the list of the apps you can add.
Tap the app's icon to add it to the App Shortcuts widget.
The current four icons appear in the App Shortcuts screen. Each of the icons includes a Delete icon in case you want to replace any of them. The app you just added appears at the 3 o’clock position on the screen.
Press the Back button to return to the Edit screen, and press the Back button again to return to the App Shortcuts widget so that you can tap any of your current app icons.
