iPhone 12 Portrait Mode zoom not showing

Yes, you can zoom while using portrait mode, but it depends on the device and camera app you’re using. On most modern smartphones:

• iPhone 12 only has Digital zoom available in portrait mode, letting you pinch in/out on the screen. This crops the image to simulate zoom, but it can reduce image quality.
• On iPhone 12 Pro models: Optical zoom (using telephoto lenses) is supported on higher-end devices. For example, iPhones with multiple lenses often switch to the telephoto lens automatically when you zoom in portrait mode, giving you a cleaner, sharper zoom.
