To become an Engineer for phones is not easy and it is also easy, ask me why?
Engineer must be very careful in all aspects for him not to enter into unnecessary debt, for example! Your friend brought you a phone to repair, instead of you to collect your full money, u collected Small change as friend to friend, my dear brother, if the phone parts u went to buy is not ok, your friend will never pay the debt, u will bear it alone.
Secondary phone engineer must always calm and bold, if u are scared, u can never accomplished your mission.
U need to be trust worthy, this is very important, I repeat this is very important
