Schematic diagrams for the Samsung SM-G950F, a 4.28 MB PDF. The sheets let you follow power from the battery connector through the PMIC and charger, then out to the display, camera, audio and RF circuits. Use them to pick test points, check which components sit on a shorted line and confirm the pin functions of connectors. Open it in a standard PDF viewer with search. Samsung boards can differ between revisions, so compare the PCB marking with the document first.
