<P> For security purposes, many mobile phone owners now lock their mobiles, requiring a passcode to be entered in order to access the device . This hinders the ability of first responders to access the ICE phone list entry . In response to this problem, many device manufacturers have provided a mechanism to specify some text to be displayed while the mobile is in the locked state . The owner of the phone can specify their "In Case of Emergency" contact and also a "Lost and Found" contact . For example, BlackBerry mobiles permit the "Owner" information to be set in the Settings → Options → Owner menu item . Android users running Android Nougat (Android 7.0) or higher also have the ability to program emergency information and contact details accessible by others through the emergency call screen when the device is locked . Emergency contacts can be added to iPhone lock screens with the iOS Health application . </P> <P> Alternatively, some handsets provide access to a list of ICE contacts directly from the "locked" screen . There are also smartphone "apps" (applications) that allow custom ICE and emergency information to be displayed as the "locked" screen . </P>
