Iphone 8 plus
My brand new iphone 8 plus (ios 11.2.6) locks out my ability to make phone calls, listen to CDs or the radio whenever my phone is using blue tooth. It does not matter if the phone is plugged in or in my purse. For example, if I am using WAZE for directions, my Nissan Rogue car screen freezes. I do receive incoming calls. I had no problem with the iphone 6 plus.
