Macro camera schematic for the Samsung SM-A21s, showing the 2MP macro module circuit, PDF, 3.82 MB. The sheet covers the connector, power rails and interface lines of the close-up camera. Technicians use it when macro mode is missing or the module is not detected, measuring supply voltages, checking the connector for shorts and tracing the signal lines. Any PDF reader opens it. Confirm the handset is an SM-A21s before matching designators, as other models use different camera layouts.
