Schematic PDF for the Samsung SM-A405F, the Galaxy A40, at board revision REV03 according to the name. The 1.39 MB document should cover the main circuit blocks, such as power management, charging, the processor and memory, and the display and camera connectors. It is useful for tracing missing voltages, checking for shorts on supply lines and locating parts during board-level repair. Any PDF viewer opens it. Make sure the PCB carries revision 03 as well, because component numbering and placement can differ on other revisions.
