Charging and data circuit schematic for the Samsung SM-A22 5G, PDF, 5.26 MB. It covers the USB port path, typically the connector pins, protection parts, charging circuitry and the USB data lines. Useful for phones that will not charge, charge slowly or are not recognised by a computer: measure VBUS and the data lines, check the protection components for shorts and trace the path to the power management side. Any PDF reader opens it. Confirm the phone is the 5G version before relying on the designators shown.
