Service manual for the Samsung Galaxy A60, model SM-A6060, in a 16.1 MB ZIP archive. Such manuals normally contain disassembly guidance, exploded views, spare part lists and level 3 data like schematics and component layouts. A repair technician uses them to find chips and test points, follow charging and power lines and check a shorted rail on the main board. Extract the files and open them in a PDF reader, and confirm that the model code on your phone is SM-A6060.
