Tapping the top bar only hides / shows the bottom menu.
To enable / disable touch you need to assign a key either to the remote or to the hardware keys. You can use the Buttons app (a system app installed in all our devices to configure the hardware keys on your device).
And yes you can also configure a auto lock / unlock while moving / stopped in the DMD2 settings.
When the screen is locked (either by using while moving setting or by manually locking it) the only way to unlock it again is either by pressing the configured hardware button (in the buttons app) or by stopping (if you are using the option to unlock when stopped)
