Samsung Galaxy A21 circuit diagrams for model SM-A215U, the US variant, packaged as a 4.24 MB RAR. Expect sheets covering power management, charging, display and camera connectors and the main processor connections. A repair technician would use them to measure rails, find test points and identify which component sits on a shorted line. Extract with WinRAR or 7-Zip and open the pages in a PDF viewer. Check that the phone label reads SM-A215U, since other A21 regional models can differ in radio and SIM circuitry.
