Samsung schematic package in ZIP form, named only with the model code T975. Judging by Samsung's naming this is likely a Galaxy Tab S7+ variant, but the file itself states nothing beyond the code. Extract it to see whether it holds PDF schematic pages, block diagrams or board layouts. Such material helps a technician trace power lines, find the PMIC and charging circuits and locate test points during board-level repair. Confirm the model number on the device label matches before relying on it.
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 @phoneSchematics. Enginerys does not host this file.
