If you want to make your iPhone shake, there are a few things you can do. The first is to go to Settings and then General. From here, you can turn on the “Rotation Lock” option. This will keep your iPhone from rotating while you’re using it, which will cause it to shake. Another way to make your iPhone shake is to take a picture or video with it and then quickly hold down the home button and the power button at the same time. This will cause the phone to restart and shake. ..
