First part of the 48 MP wide rear camera schematic for the Samsung SM-A12 (Galaxy A12), a 1.77 MB PDF. Together with the second part listed in this set, it covers the main camera connector, supply rails and data lines, useful when the rear camera will not open, shows a black image or fails focus. Check the camera supply voltages at the connector before replacing the module. The name does not give the exact model suffix or board revision, so confirm them on the handset. Readable in any PDF viewer.
