Schematic for the Samsung SM-A720F, provided as a 3.58 MB PDF. The file name lists only the model, without revision or region information. Repair use includes tracing battery, charging and PMIC rails, identifying the components around USB, SIM, display and audio circuits, and following signal lines when isolating a fault or a short to ground. Open it with a standard PDF reader and search by part designator. Check that the board version printed on the PCB corresponds to this drawing before relying on it.
