The technician had lost a small component labeled U4102 due to corrosion. Using XinZhiZao, they could identify that the missing component was an LDO (Low-Dropout Regulator) rated for 0.8A, also found in the SM-A226 model. Another forum member confirmed that XinZhiZao's database includes schematics for Samsung devices.
The output capacitor is a (470µF, 63V) with a 1µF film capacitor in parallel to decouple high-frequency harmonics. While XinZhiZao has become increasingly popular, it exists

Modern smartphone and laptop motherboards stack up to 10–12 layers of copper traces inside a single thin PCB block. If a trace breaks internally due to water corrosion or physical drops, the XZZ multi-layer function peels back these invisible layers on screen. This helps users locate exactly where to run external jumper wires. Built-In Troubleshooting Guides & Flowcharts
