Schematic in PDF format for the Samsung SM-A013F smartphone, which is the Galaxy A01 Core, with the name also hinting at G/M regional variants. The 5.17 MB document covers the board circuitry and is used to trace battery, PMIC and charging lines, display and camera connectors, and to find faults on a phone that will not power on or charge. It opens in any PDF reader. Check that the model code on the phone and the board revision match the variant shown in the drawing before relying on component values.
