I have recently upgraded to a Samsung S21 Ultra from a Razor. I am connected to my 2017 GMC intellink via blue tooth. With my old Razor (do not remember witch version of Android) I was able to receive and make calls and receive and send texts. With my Samsung S21 I am able to receive and make calls, but only receive texts,
I am not able to send texts unless I plug in a USB cable. My Blue tooth settings on my S21 for my GMC intellink connection has calls, audio. contact access and message access all enabled.

Thanks

Sorry forgot to add my S21 is running One UI version 3.1 and Android version 11.
