Samsung SM-A22 5G fingerprint sensor schematic in PDF form, 5.26 MB. The sheet documents the fingerprint reader circuit, usually the sensor connector, its supply and the communication lines to the processor. It helps when the sensor is not detected or registration fails: measure the supply at the connector, look for shorted filter capacitors and follow the lines back to the main board. The file opens in a normal PDF reader. Make sure the device is the 5G variant of the Galaxy A22 before matching component designators.
