What tablet is that and what controller?
You may need to calibrate your controller on your computer settings. The game doesn't calibrate anything with the controllers, only the tilt.
Yes, almost every software is like that. You can't connect it after launch or disconnect/reconnect. You can get very weird behavior. That's due to the OS, the game just reads whatever the values the controller is sending.
