My iPhone 8 and now my 8 plus when receiving texts makes multiple tri-tones for one single message. Sometimes the tri-tone is garbled is like the tones compressed together. I’ve changed message received tones to different tones but it still does it.
MICBAK, has a text messaging app been installed? Other than iMessages that comes by default with iPhone's?
PS: is my Ghost Buster, Verizon forum employee contributor still working here?
