Just as you can adorn the Home screen of your Samsung Galaxy tablet with widgets, you can also slap down a few right on the lock screen. In fact, the time display on the tablet’s lock screen is a widget. It’s only one of several.
To add a lock screen widget, heed these directions:
Open the Settings app.
It’s found on the Apps screen.
Choose the Device category from the top of the screen.
Don’t sweat if you don’t see that category; not every Settings app features the category tabs.
On the left side of the Settings app screen, select Lock Screen.
Select the Multiple Widgets item.
That’s it.
Normally you’d be disappointed at this point because you don’t see the lock screen brimming with widgets. Silly. You have to add them. To do that, you need to first lock the tablet.
Lock the tablet.
Unlock the tablet, but on the lock screen, swipe the Clock widget (it’s really a widget) to one side or the other. You’ll see a large plus icon. Touch that plus icon, and then choose a lock screen widget from the displayed list, such as Calendar, Gmail, Digital Clock, or what-have-you.
Multiple widgets can be placed on the lock screen, though you can see only one at a time. Swipe the screen to see others.
To remove a lock screen widget, long-press it. Drag the widget up to the Remove icon and it’s gone. You can even remove the Clock widget, in which case only the large plus icon appears on the lock screen.
