Schematic for the Samsung Galaxy M31, model SM-M315F, compressed into a ZIP archive of about 1.50 MB. The circuit diagrams let a technician follow the charging path, battery connector, PMIC rails and the display, camera and SIM interfaces, which helps in diagnosing no-power, no-charge or shorted-line faults. Extract it and open the pages in a PDF or image viewer depending on the contents. Check that the model code on the phone matches M315F, as regional variants may differ in RF sections.
