Ultrawide rear camera schematic for the Samsung SM-A21s, covering the 8MP module, as a 3.83 MB PDF. It maps the connector, supply lines and data routing for the ultrawide sensor. When only the ultrawide mode fails, a technician can compare its rails against the other cameras, look for a shorted connector pin and trace the lines back to the board. Open it in any PDF viewer. Make sure the device is the SM-A21s, since camera configurations vary across the Galaxy A range.
