Samsung SM-G955F schematic, a 4.88 MB PDF. Samsung service schematics normally include circuit sheets for power management, charging, display, camera, audio and RF sections, often with board location pages. Use it to trace rails from the PMIC, find test points and narrow down a short to a specific capacitor or IC. A PDF viewer with search makes it easy to locate nets by name. Check the board revision silkscreened on the PCB, since Samsung revises boards within one model code.
