Schematic page for the 48MP wide main rear camera of the Samsung SM-A22 5G, delivered as a 5.26 MB PDF. It shows the camera connector and the supply and data connections feeding the primary sensor. Technicians use it to check camera supply voltages, look for a shorted rail on the connector and trace the interface lines when the main camera fails or the camera app crashes. It opens in a standard PDF viewer. Check that the module and board belong to the 5G model, because the A22 LTE uses a different camera layout.
