Samsung Level 3 Repair Guide

The document provides a block diagram of a system. It shows various components connected including an OCTA processor, touchscreen controller, LCD display, vibration motor, camera module, USB ports, and a PMIC for power management. The PMIC receives signals from components and controls power delivery over various lines like battery charging, motor power, and voltage enables for other parts.
