For some Android phones, you may not be able to increase or decrease the volume during setup by using the physical volume buttons, but you can adjust this in the Sounds section of your settings app.
To increase your phone’s audio settings:
- Go to your phone’s settings
- Tap Sounds
- Tap Volumes
- Drag all sliders to the right
- Go to Recent Apps and open the Canary app
The audio slider in the Canary app should be all the way to the right, and you should be able to proceed with setup.
