first of all: thanks a lot for the app - and yes, it makes sense that rSAP App supports Samsung S4/ i9505. Especially since I am now on Android Marshmallow (CM 13). Stock ROM worked nice with rSAP and Audi Connect in A6 out of the box by the way.
Anyway, as I am know on your App (Bluetooth - Stack in CM 13 is damn buggy): Is there a possibility to hide the splash screen info that rSAP App is running? Just deactivate the app in the app-specific sub-menu "App-Benachrichtigungen"? Or may I miss important messages from the app in case of disabling splash-screen messages for the app? Or may that crash the app?

A second but less important point: Is it possible to hide the rSAP icon from the status bar (anyway the icon in the left upper corner does not really annoy me...)
Best regards
Manu
