With the Help of a Button Mapper, You can Use Specific Apps By Performing Specific Actions on Your Android Device.
It’s not just your phone that sets these parameters. A device can be programmed to carry out a specific action with a predetermined outcome. You can, for example, double-tap the back button to open the camera application.
Use the Button Mapper app, available on Google Play, to accomplish this. This will allow you to set specific actions, such as how many times you want to tap or how long you want to hold the screen down, depending on your preferences. If you know how to map your device properly, the possibilities are virtually limitless.
