Schematic section for the 13 MP wide rear camera of the Samsung SM-A20S, provided as a 4.64 MB PDF. It shows that camera module connector, supply rails, control and data lines, and the related filtering components. Technicians use it when the main camera fails, shows errors, or a connector is damaged, checking each voltage and line against the diagram. Open it in any PDF reader, and match the connector on the board before probing, since the rear modules sit close together.
