Service material for the OPPO R7s smartphone, packed as a 1.29 MB RAR archive whose name gives only the model and no hint of the exact contents. Expect schematic or layout documents, but open the archive and check what is actually inside before relying on it. For phone repair such files help trace PMIC rails, battery and charging paths, display and camera connector pinouts, and locate test points when chasing a short. Confirm the board version printed on the PCB matches the document before measuring against it.
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 @SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
