However, a schematic alone only tells you how components connect logically; it does not tell you where they are physically located on the board. For that, technicians use a file. Boardview software (like ZXW Tools, PhoneBoard, or Pragmafix) provides an interactive 3D or 2D map of the actual physical board layout. Together, the schematic diagram and the boardview file form the ultimate toolkit for tracing short circuits and diagnosing dead devices. 2. Core Architecture of the Samsung Galaxy S9 Logic Board
