Caller cant hear unless on speaker
When calling someone, they automatically tell me they my voice is muffled or that they cant hear me. In the beginning I chalked it up to bad signal, but Ive discovered that the audio quality for them suddenly fixes when i set my phone to speaker. I have no problem hearing them, but they cannot hear me unless its on speaker. Is there a reason for this? What can I do to better the quality when not on speaker?
