Schematic archive for the Samsung F926U, the US variant of the Galaxy Z Fold3, 2.11 MB ZIP; the trailing W token is not explained and may indicate the Canadian sibling. US boards use a different chipset layout from global models, so do not mix them up with SM-F926B documents. Use these pages to trace PMIC rails, charging circuits, flex and connector lines and to locate shorts. Confirm the model code on the phone before relying on references.
