Handsfree and headset audio schematic for the Samsung SM-A23, contained in a 2.78 MB PDF. It outlines the headset jack or wired-audio path, including detect lines, microphone input and left and right outputs to the codec. Use it when wired headphones are not detected, sound only plays on one side, or the headset mic fails during calls. Trace continuity and protection components against the drawing, and confirm the board version of the phone in front of you matches the diagram.
