Samsung archive covering the A750F, A750FN, A750G and A750GN model variants, ZIP format, 14.8 MB. The name lists the supported regional versions but not the contents, so check after extraction whether it holds schematics, a boardview, service documents or firmware. Confirm the exact model code of the phone being repaired is among the listed variants before using the data. Repair files like these let a technician follow power rails, locate components and test points, check the charging path and diagnose display or no-power faults.
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 @tamirat_moobile. Enginerys does not host this file.
