Schematics for the Samsung SM-G903F, the Galaxy S5 Neo, packed in a 15.3 MB ZIP archive. The relatively large size suggests a full set of pages, covering the PMIC, charger, application processor, memory, RF front end and peripheral connectors. Technicians use these diagrams to follow voltage rails, decode net names between pages, find the right point to measure when a phone is dead or not charging and confirm part values. Unpack and open with a PDF viewer. Confirm the PCB revision printed on the main board matches the schematic.
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.
