Schematic PDF of 8.36 MB for the Samsung Galaxy A32 5G, model SM-A326B; the Spanish title says complete schematic. Pages show the power management outputs, battery and charger circuit, USB port, RF sections and connectors for display and cameras. A technician uses it to trace a rail back to its source, locate parts on a shorted line and check signals while repairing at board level. The 4G A32 is a different board, so make sure the model code printed on the PCB matches SM-A326B before using it.
