To enable Back Tap, go to Settings > Accessibility > Touch and select Back Tap. You can assign shortcuts to a double-tap or a triple-tap. You can now tap the back of your phone twice or thrice to execute the action.

The iPhone 15 camera is capable of capturing photos in 48MP resolution and also allows you to switch between different modes, namely HEIF, ProRAW, and ProRAW Max. Each image format takes up a different amount of space on your phone. For instance, HEIF takes up only around 5MB while ProRAW occupies approximately 75-100MB.

To switch modes, open the camera app and tap on the "HEIF Max" button at the top right corner. You can tap it again to switch to the other modes. You could also hold on to the button to access all the modes and tap on the one you require.

To switch the default format for Pro mode, go to Settings > Camera > Formats > Pro Default. In the Pro Default settings, you can choose the default format size for Pro Mode.

This feature is extremely useful as RAW photos occupy a huge chunk of space on your device. Switching to HEIF means sacrificing very little space for great-quality images.


3) Focal length change in the camera app

Another way to do this is to go to Settings > Camera > Formats > Photo Mode. You can select between the different focal lengths based on your needs.
