IOS 13.4.1 Update
I updated my Iphone 8 ios to 13.4.1, now i can not hear when I make or receive phone calls. The speaker button is grayed out when receiving or making calls. I can hear them with Airpods or any Bluetooth headphones. I have tried cycling power. Checked do not disturb, airplane mode, silent mode. This started immediately after update without me changing any settings.
