If you want to record a screenshot quickly with the Huawei P20 Pro, you can use a special function. And that is the "Smart Screenshot". With this method one must knock twice with a finger knuckle on the display, in order to store the indicated display contents.
This is very fast and in many cases easier than using the key combination. In order for the Smart Screenshot or the knocking with the ankle to work, you first have to activate it in the Android settings.
This works as follows:
1. Open the settings and then Intelligent Support
2. Then go from here to "Motion Control" and then to "Smart Screenshot "
3. Activates the option with the slider. Now the Screenshot option is active. Now knock twice fast on the display of the Huawei P20 Pro to take a screenshot.
The displayed screen content is then captured and saved as an image.
