Schematic for the Samsung SM-J530F handset, delivered as a 4.73 MB PDF without a revision stated in the file name. It helps with tracing power distribution, following signal lines between the SoC, PMIC and connectors, and locating components when hunting a short or open circuit. Use any PDF viewer, ideally one with text search for net names. Before measuring against expected values, make sure the board revision on the PCB matches the one documented, as minor layout changes occur between production runs.
