PSA: Shadow Dash Disconnecting Issue
 

I've been chasing an odd bluetooth disconnecting issue on my new Galaxy tablet that was kicking my ass. Every 30 seconds the Bluetooth connection was dropped and would reconnect a few seconds later. I tried turning off Bluetooth scanning, pulled all other Bluetooth devices out of the car and even bought a different Bluetooth adapter for the ecm. What was odd is every now and then it worked fine for hours.

The fix, there's an option in shadow dash to disconnect if power is removed from the tablet. Well when this tablet would fully charge it would disconnect itself from power triggering this setting to disconnect from Bluetooth ......mother fucker! When it was working was when the tablet was charging. I feel dumb.
