Apple allows you to adjust the double-click speed of the dedicated Camera Control button on the iPhone 17 and iPhone 16 series, so you can use this feature even if you have difficulty quickly clicking this button in its default configuration.

Camera Control, a physical button with haptic feedback on the right side of the iPhone 16 (except 16e) and iPhone 17, used for launching and interacting with the camera, can distinguish between light and hard presses.
By default, clicking Camera Control once opens your designated camera app, but you can change this to a double-click gesture to avoid accidental launches. And with iOS 18.2 and later, you can also adjust the double-click speed of Camera Control, much like you can adjust click speed for the iPhone side/home or iPad top/home button.
Adjust Camera Control double-click speed on your iPhone
1) Open the Settings app and tap Camera > Camera Control.
2) Make sure you’ve set the camera to open with a double click instead of a single click. Then, tap Accessibility from the bottom of the screen.
3) Select Default, Slow, or Slower under the Double Click Speed heading.
- Default: The default double-click speed.
- Slow: Requires a slower speed to register the double-press gesture.
- Slower: Use the slowest double-click speed.
You can also change this from Settings > Accessibility > Camera Control > Double Click Speed.
This Double Click Speed accessibility setting is similar to the Double Light-Press Speed option for controlling how fast you need to press the Camera Control button for your iPhone to recognize a light double-press.
The built-in Camera app uses the light double-press gesture to switch between tools such as zoom, exposure control, lenses, depth, photographic styles, and more.
Apple also provides APIs for developers to use Camera Control in their camera apps. An update to the Kino app, for example, introduced basic Camera Control. You can use Camera Control in Kino to adjust your exposure, tweak focus, or quickly switch between grades.
As previously reported, iOS 18.2 also brings a two-stage shutter to Camera Control, where you lightly press and hold the button once to lock your exposure and focus and then press harder to take an image or record video, DLSR style.
