Schematic diagram in PDF form for the Samsung SM-G361H smartphone, a 3.17 MB document covering the main board circuitry. The file name gives only the model code, so no board revision is stated. Technicians use a phone schematic like this to follow power rails from the PMIC, trace charging, display and baseband signal paths, and identify components around a suspected short. Any PDF viewer opens it; confirm the model code on the device label matches before relying on part values or connector pinouts during repair.
