rc charge receptacle & factory phone cable

Who has affirmed this junction point can introduce trouble?
By trouble, will nougat os flag junction error?
Will djigo4 flag junction error?
Or nobody will flag junction error?
If nobody warns, then how to affirm junction deficient?

the factory provided rc:phone 4cm cable seems to just insert itself resistance free into rc charge receptacle. That friction free insertion concerns me knowing gold leaf springs provide ampere transfer are making interface contact with nearly zero friction, shear friction
