If you’re like most people, you probably use your iPhone to do things like check email, make phone calls, and play games. But there are a few things you can do that require more than just tapping and holding on the screen. For example, if you want to control your iPhone’s camera, you can use the Command button to do it. To use the Command button, hold down the Command key and then press the desired function on your iPhone’s screen. For example, if you want to take a picture with your iPhone’s camera, hold down the Command key and then press the “take picture” button.
