The upcoming iPhone 15 Pro and Pro Max are expected to come with an action button — similar to the one on the Apple Watch Ultra — that replaces the device’s ring/silent switch. But now, we have a better idea of what it might be able to do.

As spotted by MacRumors, code in the iOS 17 beta 4 suggests you can program nine different functions into the action button, potentially allowing you to quickly access the Camera app, turn on the flashlight, launch the Translate app, and more.
