Headset jack schematic page for the Samsung SM-A10, provided as a 1.22 MB PDF. It shows the jack detect line, stereo audio outputs, the headset microphone return and the protection components near the connector. Use it when earphones are not recognised, sound comes from one side only or the phone stays in headset mode with nothing plugged in. Measure the detect line and audio paths against the drawing. Any PDF reader opens it. Confirm the handset is an SM-A10 first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @phoneSchematics. Enginerys does not host this file.
