Samsung SM-A11 schematic excerpt covering the 5 MP ultrawide rear camera, as a PDF of 4.34 MB. The pages trace the ultrawide module connector, its power rails and the control and image data lines toward the processor. Handy when the ultrawide lens will not open while other cameras work, letting you measure supplies and check connector pins and filters. Any PDF viewer opens it; confirm the board revision printed on the PCB matches before trusting the designators shown.
