iPhone XR call quality
Updated iPhoneXR to 14.0.1 but the other person still cannot hear me well, still garbled/muffled or cutting out, they can only hear me if i face the bottom microphone directly to my mouth when speaking. Works fine if i'm on speaker mode though, also ok with headphones, wireless earbuds. Facetime audio, FB Messenger, Viber all works well when phone is used normally over the ear. Issue is only when calling using the carrier and using the phone over the ear. Doesn't seem to be a hardware issue. Audio/Video records well using front and back cameras, voice memo is also good.
Did not have this problem with my 7 plus and 8 plus.
