Hey there, Davidwmerlin! I'd be very upset if my calls were going the way your calls have. I apologize for that! Let's delve deeper into this matter. I see that your audio is reliable during speakerphone mode calls. Do you use a headset (wired or wireless)? If so, how do those calls go? Has your device been damaged in any way? Do you notice any consistent factors in these trouble calls (same callers, same location when the call is made, only on incoming/outgoing calls)?
