I bought Samsung M31 from Amazon yesterday. Everything seemed perfect until when I called my friend and put him on loudspeaker. His voice was blurry. Then I called other people as well and found Male voice(generally low frequency) is becoming blurry. Female voice (generally high frequency) is ok. Even if I play music, it's the same. Is this Hardware faulty or Samsung M31 spec itself has limitation?
