Recently, the phone has been difficult to connect to my normal Bluetooth devices -- watch, car, headphones. Now it will not connect at all. I've discovered the phone shows TWO system applications for Bluetooth -- one is version 7.0, the other is version 5.30.36. I cannot "Force Stop" or disable either. All Bluetooth devices show as "MISC" in the Bluetooth settings, and it appears there are double the number of devices listed -- perhaps because both applications are active? The phone will not recognize any devices, returning the error: "Cannot pair with null". Thoughts? V10 is running Android 7.0 kernel version 3.10.84. I have no updates available according to the update manager.
