Q49: How can I exit the third party app interface when there is no "Back button? on indoor monitor"

A49: 

If the "akuvox" is detected in the app's packet name, the "Back button" will not be shown.

So now in new firmware of indoor monitor, we develop it like:

When it is in the third party app interface, indoor monitor will show the menu bar at the bottom.

Icons from left to right: Back button (click to return), Home button (click to leave the third-party APP interface and return to the home page of indoor monitor), and multitasking button (click to view the currently executing process).
