Rear 2 MP macro camera circuit from the Samsung SM-A02S schematic set, saved as a PDF of about 3.70 MB. It documents the macro module connector, its power rails and control lines, which helps diagnose a macro camera that is missing from the camera app or shows a blank preview. Use the drawing to locate the supply pins and measure them with a meter, then inspect the nearby passives and connector for corrosion. Open with a standard PDF reader and confirm the phone model on the board before relying on component values.
