Schematic section for the 5 MP ultra-wide rear camera of the Samsung SM-A12 (Galaxy A12), a 3.36 MB PDF. It documents the connector, supply voltages and interface lines for that module, letting you check why the ultra-wide mode will not switch on while the main camera works. Measuring its rails at the connector and checking for a damaged filter or cracked flex are typical first steps. The name gives no variant suffix or board revision, so match designators with your mainboard before replacing parts. Opens in any PDF reader.
