The Camera Control button on your iPhone (also known as the Action Button on iPhone 15 Pro and later, or a gesture control on other models) now offers enhanced customization options in iOS 26. This feature allows you to streamline your photography workflow by assigning specific actions or apps to the button, making it faster and more intuitive to capture moments or launch your preferred camera experience.
In iOS 26, the Camera Control button can now be configured to launch any compatible camera app installed on your iPhone, not just the stock Camera app. Furthermore, you can now disable the 'Require Screen On' setting, allowing the camera app to open directly even when your phone's screen is off, removing an extra step for quick captures.

Consider your primary use for the Camera Control button. If you're a quick snapper, disabling 'Require Screen On' and linking it to the default Camera app or a fast-launching third-party app is ideal. If you frequently post to social media, setting it directly to an app like Instagram will save you precious seconds. Experiment with different apps and settings to find the configuration that best suits your daily needs.
The Camera Control button customization in iOS 26 significantly enhances the iPhone's camera accessibility and user experience. By allowing users to select their preferred camera app and bypass the lock screen, it provides a faster, more personalized way to interact with the camera. This feature is a powerful tool for anyone looking to optimize their photo and video capture process on iPhone.
