Samsung SM-J710F schematic in PDF format, a fairly large 6.27 MB file with no revision noted in its name. It suits board-level work such as following power rails, locating components on a shorted line, checking the charging and USB circuitry and identifying connector pin assignments. Open it in any PDF reader and use text search for net or part names where the file allows it. Compare the PCB revision silkscreened on the board with the drawings before trusting component positions or values.
