If you’re like most people, you probably use your iPhone to take pictures and videos. But if you want to zoom in on a picture or video, you have to use the pinch gesture. Here’s how to do it:

  1. Open the picture or video you want to zoom in on.
  2. Swipe left or right until the area of the picture or video you want to zoom in on is highlighted.
  3. Use your fingers to pinch the area of the picture or video that you want to zoom in on. ..
