Schematic package for the Samsung Galaxy S21 Plus, model SM-G996B, supplied as a ZIP archive of about 4.86 MB. The name carries no board revision, so confirm the variant against the label inside the phone before relying on it. A technician uses a smartphone schematic to follow power rails from the PMIC, trace charging and display lines, and identify the components around a fault such as a short on the main supply. Unpack it and open the diagrams in a PDF viewer, then cross-check part references with a boardview if you have one.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematic_mobile5. Enginerys does not host this file.
