Schematic package for Samsung SM-W727V, SM-W720 and SM-W723 models, supplied as an 11.4 MB ZIP. Because the set spans several model codes, check which variant you have, as carrier or regional versions may differ in some circuits. The drawings support tracing battery and charging paths, PMIC rails, display and keypad lines, and locating components when hunting a short or dead rail. Extract the archive and open the pages with a PDF reader or whatever viewer matches the files inside.
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.
