Click on the emulator 3 times and the screen will zoom in

If you click on the desktop of the game or the emulator 3 times in a row, the screen will zoom in. It may be caused by turning on the Android accessibility settings by mistake. The specific closing steps are as follows:

1. Enter-System Application-Settings on the emulator desktop

2.  Pull to the bottom to find "Accessibility". Find the "magnification gestures" and keep it closed.
