Z2 demo video

[azzido]

Hello,
does anyone knows the code that needs to be typed to turn the phone into demo video? 
I found the videos on a storage but no matter which player I will play it it doesn't have an audio...

Anyone knows how to enable audio on this video? (there are a few of them with different language).

Thank you.

How do u turn off the demo when on charge so the screen sleep??

You can't - Demo mode is for shops etc which haved their phones always connected to a power source - So all you can do is either turn the phone completely off or turn off demo mode as seen above via the code
