do u guys have any idea how to clean the ust of the metal contacts etc....??

you will have to open your phone. be sure to have the right screwdrivers, otherwise you will damage the screws

Dust can easily be cleaned from your phone by taking it apart using a torx t6 screwdriver and then using compressed air to clean the main board and components.
