Apple's latest iPhone 16 models include a new Camera Control button (located on the lower right-hand side when holding the phone in portrait mode), and the latest iOS 18.2 software update adds a handy new piece of functionality to it.
iPhone 16 users now have the option to lock their auto exposure and auto focus settings with a light press of Camera Control. The option isn't on by default, but you can enable it in the following way.
- Open the Settings app on your iPhone.
- Select Camera.
- Select Camera Control.
- Under "Light Press," toggle on the switch beside AE/EF Lock.
That's all there is to it – the change should take place immediately, allowing you to lock in auto-exposure and auto-focus settings with a light press before you take your shot.
Require Screen On
In iOS 18.2, Apple also added a new Camera Control toggle in Settings ➝ Display & Brightness. The new toggle is called Require Screen On. When enabled, this setting requires that your iPhone screen is illuminated before a press of the Camera Control button will open the Camera app or a compatible third-party camera app. It's a handy option if you find yourself pressing the button accidentally.
