My Core Prime is running Android 4.4.4; it's a Tracfone. Unlike my three previous Tracfones, it has stopped connecting to my Kia Sorento's UVO Bluetooth. The phone is still listed in the UVO's list of devices, but the connection fails. The Kia forums blame this on the phone's software updates & suggest that we ask the phone company to roll back the software updates. Is there another fix? TIA.
