If you own an iPhone 11, there’s a good chance that there is a gray box on the bottom of the device. This box is known as the “Face ID” and it helps you unlock your phone. If you don’t have Face ID, then you’ll need to use another method to unlock your phone. Here are some tips on how to remove the gray box on iPhone 11:

  1. Open up the Settings app and select General > Security > Face ID.
  2. Under “Face ID,” select “Remove.”
  3. Once Face ID is removed, your phone will be unlocked again.
