Hi,
I´ve tried all recomended procedure (updating newer software / OS, deactivating noise reduction, checked the main mic function in service mode using mic loopback - OK). Now I´ve tried to deactivate upper noise microphone by putting a bit of adhesive tape over its pine hole. It seems the phone works now much better.
