When I press the Home key on “lock screen”, a white square box appears.
Q : When I press the Home key when the device is in "lock screen", a white square box
appears. Why is that?
A :It means that the touch gestures feature to access Multiple widgets is accessible.
Then, you can drag from right to left on the Lock screen in the area near the top of the screen (press the Home key to see the area you can wipe in to access the multiple widgets).
These settings are applied only when you set the swipe lock option.
