About iPhone 12

Unlike older models like iPhone 6, 7, X, SE, and 8, newer models like iPhone X, 11, 12, and above have no Home button. If you were used to turning off your iPhone with the home button, you may find it difficult on the iPhone 12.

In iPhone 12, Apple has gotten rid of the home button for fingerprint scanning and replaced it with the Face ID feature. This is a deliberate move to prevent people from accessing your iPhone while you are sleeping or unconscious. It is also effective to prevent you from accidentally powering off an iPhone 12 when in a pocket or bag. You surely don't want to miss important calls and updates from your colleagues, family, and friends.
