The user needs to have a fluid way of exiting the sandbox mode whilst ensuring that Talkback is enabled when the user returns to the main menu, due to Talkback being disabled whilst the sandbox mode is active.
To exit the sandbox mode, the user will hold the two volume buttons to re-enter Talkback. Upon re-entering Talkback, the app will automatically detect that Talkback has been re-enabled and exit the sandbox mode with closure.
So if the user at any point during the sandbox mode, holds the volume keys and re-enters Talkback, the mode ends and the user is returned back to the main menu with TTS as closure, something like "Talkback re-enabled, exiting sandbox and returning you back to the main menu".
