- Common Fault Symptoms & Motherboard Repair:
* Dead Phone (No Power / No Boot): Device fails to power on completely due to failure in generating the initial power rail; on a DC power supply, it draws zero current or hangs at very low current.
* No Charging (0.00A on USB Meter): Phone does not detect the USB charger or fails to pull charging current.
* Fake Charging / Slow Charging: Charging battery animation is displayed, but battery percentage drops or does not rise.
* Boot Loop / Stuck on Samsung Logo: Unstable secondary LDO voltage lines cause the Android system to restart repeatedly during bootup.
* Overheating / Short Circuit: VBUS or VBAT line breakdown inside the IC causing the chip area to heat up rapidly under power.
