Ok, I'm at a loss. I can't get either of my rx8 gen2 esc's working with the hotwire android app version 6.11.0 and previous version using a hotwire 2.0 interface. Note: this works perfectly on a PC

These are the devices I've tried and the results:
Samsung Galaxy Tab Pro Running v5.1.1
Used both OTG and regular USB cable
The app starts then I get locked up black screen

Samsung galaxy tab 4
Used both OTG and regular USB cable
The app does not start after plugging cable into tablet. I connect a battery to the esc and turn it on. The interface powers on but has solid green LED instead of flashing

I get the same above results on a Droid Razr running v4.1.2
