Help How to change the app that starts after pressing power button twice?

[andfo]

On my android phone, if I press the power button twice, the camera app is automatically started. I want to change that to another app. I don't need the camera app. I want to start another app. How can I change this?

It will depend upon the device and the apps if the app you desire has this capability.

Settings
Buttons & gestures
Power key

Another option is to change your Assistant app, which is activated by a long press of the center (Home) button on the navigation bar.
