Samsung SM-J530F service schematic in PDF, 4.73 MB. The name carries just the model code and no board revision. Bench technicians use this kind of document to follow power rails out of the PMIC, trace the USB charging path, check display, fingerprint and camera connector pinouts, and find components connected to a line suspected of a short. Any PDF reader will open it. Make sure the model on the phone label matches the document before relying on component designators or values.
