Schematic set for the Samsung Galaxy A10s, model SM-A107F, in a 2.64 MB RAR archive. No board revision appears in the name. These drawings are handy for tracing battery and charging circuits, following display and connector signals, and locating parts sitting on a shorted supply line during board-level repair. Extract the archive with any RAR-capable tool and open the pages in a PDF viewer. Check the model code on the phone matches SM-A107F, because Samsung regional variants can differ in layout and components.
