In order to avoid getting into such a situation where you buy an iPhone part that
later fails to work after your technician fits it in the iPhone, it is recommended that you just give the entire task of identifying the damaged iPhone part as well as installing to the technician so that if he/she damages it in the process, he has no advantage of telling you that the part you brought along has failed to function as supposed and thus shift the blame to you. Giving that person the overall task will turn out cheaper, convenient and much sensible than otherwise doing it yourself. For contact us iPhone part
