So the text message function was working flawlessly from day one up until yesterday. I have a Samsung S7 running 6.01 OS. I tried deleting the phone from the car, unpairing from my phone and I also made sure it was allowed to access messages and contacts. The last successful text message I got was at 8:00 AM yesterday. I did upgrade my phone software yesterday morning but that was at 6:30 AM. Any advice help would be greatly appreciated.
