How to capture a knuckle screenshot?
1. Open “Settings” and select “Smart assistance”.
2. Touch “Motion control > Smart screenshot” and turn on the “Smart screenshot” switch.
3. Full screenshot: Knock the screen firmly with your knuckle twice to capture the current screen in full. (By default, screenshots are stored in “Gallery”, within the “Screenshots” folder.)
4. Partial screenshot: Knock the screen firmly with your knuckle. Drag your knuckle around the area you want to capture, and then return to the starting point. Your selection is displayed on the screen; the area inside the blue line will be captured. You can also select the screenshot box at the top of the screen for different screenshot shapes.
