iPhone 12: I cannot hear my mom if I call her but she can hear me.
My mom has a newer flip phone from Lively (formerly Greatcall) and before updating to iPhone 12 (previously iPhone 8) everything worked fine as we could hear each other regardless of who initiated the call. Now when I call her she can hear me but I cannot hear her and have to instruct her to call me back. When she calls me directly everything works fine.
My wife has the exact same issue after updating to iPhone 12 so it seems like an iPhone 12 problem.
My wife did have an unrelated issue so recently had the phone replaced with another iPhone 12 but is having the same exact issue when calling mom on her flip phone.
We've tried resetting Bluetooth, airplane mode on-off, rebooting the phone, reinstalling the software but nothing works. Since only the iPhone has changed (from 8 to 12) it seems to be an iPhone issue but cannot find a fix. Is there any information on how to resolve this issue?
Thanks!
