The Huawei P20 Pro has several features built into its software, including drawing on the display. This means that you can switch to an app by drawing a letter on the screen.
As an example. Drawing the letter C opens the camera app. But now it is often the case that this function is often activated when playing a game like Clash Royale.
This is of course unfavorable, because the game is interrupted and you might lose by this short drop-out.
If you want to deactivate the drawing on the screen of the Huawei P20 Pro, please proceed as follows:
1. Open the settings
2. Now select "Intelligent Support"
3. Go on to "Motion Control" and then to "Draw"
4. Deactivate the function by simply moving the slider from "On" to "Off"
Then you can continue playing the game on your Huawei P20 Pro again without interruption by a function like "Draw".
