If the child opens an app that is closed right now, the phone goes back to the home screen and shows the break screen once: “Break now”, your words and the time left. While the child stays on the home screen or in an allowed app, the screen doesn't come back. Any other app — from the app list, a widget, a notification or recent apps — brings back the home screen and the break screen.
- “Call” and “Messages” — ordinary calls and SMS work during any break, schedule or limit.
- “SOS and calling the family — in KidPair”.
- “Ask to end the break” (during a schedule — “Ask for an exception”, when time has run out — “Ask for more time”). The child can ask again after 10 minutes.
- “Close” (and the Back and Home buttons) — the home screen.
Always open, and no adult can change it: the phone's home screen, the ordinary Phone app and the call screen, the SMS app, emergency calling, Android's own windows, the keyboard and KidPair. Besides these, the apps you kept available for the break or as schedule exceptions work too.
Like every restriction on Android, this works as far as the phone allows. For example, what a home-screen widget shows by itself can't be blocked.
