Schematics for the Samsung SM-A800F, a large 10.4 MB PDF that likely includes multiple board sheets. Samsung service schematics show the PMIC rails, charging circuit, RF sections and connector pinouts, allowing a technician to trace a missing voltage or a short on a supply line and identify unknown components. No board revision appears in the name, so compare the PCB markings with the diagram. It opens in any PDF viewer, and the separate disassembly manual for this model covers mechanical teardown.
