Full schematic for the Samsung Galaxy J1 model SM-J111F, provided as a 3.05 MB PDF with a title partly in Persian. The diagrams show the power management circuitry, charging path, display and camera connectors, and the component reference designators. Technicians use them to locate parts and test points and to trace shorts on supply rails. Any PDF reader opens it, and the board revision in the document should be compared with the markings on your PCB.
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 @mobileshematic. Enginerys does not host this file.
