Schematic PDF, 4.45 MB, for the Samsung Galaxy A22 5G, model SM-A226B, titled in Spanish as a complete schematic. Pages typically show the PMIC and its rails, charging path, USB connector, RF blocks and connections to the display and sub board. A technician uses it to trace a failed line, locate the components on a shorted rail and verify signal routing during repair. Do not mix it up with the 4G SM-A225F, which uses a different board, and check the board revision on the PCB before use.
