Schematic package for the Tecno / Infinix model coded X688B, compressed into a 951 KB ZIP. The name provides no board revision or sub-board details. Phone schematics let a technician follow battery and charging circuits, PMIC output rails, display and camera connector pinouts and audio paths, and are useful for spotting which line is shorted to ground. Compare the model and board markings on the phone's PCB with the document before relying on component references.
