Locked Home Screen. One meaning of the term locked iPhone refers to an iPhone with a locked home screen. All iPhones have a lock feature that allows a user to lock his home screen when the phone is not in use to prevent him from accidentally activating the touch screen while the phone is in his pocket.
Activation Lock is designed to prevent anyone from using your iPhone, iPad or iPod touch if you ever lose your device. It starts working the moment you turn on Find My iPhone. From then on, your Apple ID and password will be required before anyone can turn off Find My iPhone, erase your device or reactivate it.
