Schematic in PDF form for the Samsung Galaxy A50, model SM-A505F. The name states no board revision. Technicians use such service diagrams to follow power lines from the battery connector and PMIC, diagnose charging, audio or display faults, and find capacitors and test points when a line is shorted to ground. Check the board version printed on the PCB against the schematic pages, since component layouts and part values can differ between regional variants and revisions.
