Fake Charging Case. How Important a small Component can be in a Circuit.

Model :- Redmi 3s
Fake Charging Case, how Important a small Component (Resistor in this case) can be in a circuit. Actually, Phone came to us for fake charging issue, And we diagnosed it and found that some technician has removed some components from PCB like Zener diode, Resistor, etc. And the resistor R1902 which was missing was in series with the USB connector and PMI ic, which was very important for charging circuit to work properly. So we put the missing component (R1902) and it worked for us.
