The Action Button Across All Devices
Apple decided to ditch the Ring/Silent switch on the iPhone 15 Pro models and added a new Action button that lets you perform basic actions like turning the flashlight on or putting your iPhone in Silent mode.
Unfortunately, this feature was exclusive to the iPhone 15 Pro models. The base iPhone 15 and iPhone 15 Plus kept the Ring/Silent switch.
While the switch is so iconic it’ll be hard to say goodbye, it’s time for all iPhone models to feature the Action button. The good news is that, according to some leaks, Apple thinks the same way and plans to implement the Action button for all iPhone 16 models this year.
