Schematic set for the Meizu MX4 smartphone, packed in a 1.32 MB zip. Phone schematics like this cover the PMIC, charging and battery circuits, display, camera and RF sections, with signal names and component references. They help when tracing a short on a rail, checking a missing voltage or finding the connector pins for a no-display fault. Extract the archive and check the format of the pages inside. Compare the board marking with the document before trusting part positions.
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 @esquematicosparatodos. Enginerys does not host this file.
