Are there apps known to disrupt Galaxy S5 /BT connections?

A

AC Question

The connection between my Galaxy S5 and 2014 Prius BT terminates within 30 seconds and the connection can not be reestablished without rebooting the BT. This does not happen with another Galaxy S5. Also, it does not happen when the S5 is connected to another BT. It seems that it might be caused by an app on the phone that can turn off the Prius BT. Does anyone know more about this problem?
