The digital sigange presentation takes over the screen every time I use a different source

If you have a professional Digital Signage screen with Android (SoC), you could face the issue that the presentation takes over the screen when you use the HDMI source, for example.

1. Press the back button:

2. It could be the case that our application tries to restart the presentation. If so, you see the following pop-up. Please click on cancel:

3. The Digital Signage presentation is stopped. Please, make sure that you disable 'restart on exit.' You can now switch the source without getting interrupted by the Digital Signage presentation. If you want to restart the Digital Signage presentation, please reboot the screen (off/on).
