How to open WhatsApp with the Action Button

What else can I do with the Action Button?
If you choose to open WhatsApp with the Action Button then you can’t do anything else with it unless you setup a slightly more complicated Shortcut. We’ve got aShortcuts tips and tricks featurethat can help you create more complicated tasks on Shortcut, such as changing what the Action Button does when you’re at home and when you’re not at home. Use this and you could have WhatsApp open when you’re at home, but Google Maps open when you’re out for example.
On a more basic level though, the Action Button can be set to turn on Silent Mode, set a Focus or choose a Camera mode, like Selfie, Portrait or Video. You can also choose for it to turn Torch on and off, start and stop recording a Voice Memo and launch Magnifier. There are Accessibility options too, with the ability to choose from a range of features including turning on Voice Control andGuided Access. The more complicated option is Shortcuts as I mentioned, but this also gives you flexibility with the Action Button, given there are any number of actions you can implement so play around and see what you can make it do.
