The fourth-generation iPhone SE will have an iPhone 15 Pro-style Action Button, among several other significant new features, according to the leaker...
The Action button, which could be similar to the Apple Watch Ultra’s Action button but with more phone-focused options, is expected to be a new physical button on the next-generation Pro iPhone models that replaces the Ring/Silent switch. The Action button would allow users to quickly access various functions and settings without necessarily unlocking the device or navigating to an app.
