Hi Alex,
You were right. I installed the APK with “Copy SMART Mobile to device”, and additionally deselected kiosk mode in the Cybertracker properties before exporting my project. The app stops asking me for the pin.
However, when using SMART Mobile without the kiosk mode, the app had some GPS trouble and gave me an error when I wanted to end my patrol. So, we will use it with the kiosk mode anyway.
Waiting for SMART 7 then 
Thanks for your help
Jackie
