operation of iPhone. You can still receive calls and text messages, and you can adjust the volume
and use the mic button on the iPhone earphones when listening to music or on a call.

choose a time.

By default, iPhone doesn’t require you to enter a passcode to unlock it.
Set a passcode: Go to Settings > General > Passcode Lock and set a 4-digit passcode.
