Schematic documents in PDF form for the Samsung SM-A207F, the Galaxy A20s, packed in a RAR archive of about 3.61 MB. The name gives the model code but no board revision, so check the PCB markings against the sheet headers. Samsung service schematics typically cover the PMIC, charging, RF and connector circuits, and help a technician trace a missing voltage, locate the parts on a shorted rail and read test points. Extract the archive and open the PDFs in any reader that supports text search for net names.
