Schematic for the Samsung Galaxy A20, model SM-A205F, packed as a PDF inside a RAR archive. Phone service schematics like this show the PMIC power rails, charging circuitry, connectors and the main block layout. They help a technician diagnose no-power, no-charge or display faults and locate the relevant components on the board. Extract the archive and open the PDF in any reader. The name gives no board revision, so compare the PCB markings with the document before relying on component values.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @GENERAL_SMART_PHONE_SCHEMATICS. Enginerys does not host this file.
