Clean the Antenna Port both male and female. You may also use Magnifying Glass while cleaning to give a deeper clean. Any residential liquid portion may behave to signal collapse or electric current interpolation tension resulting massive signal malfunction. It may resolve your issue I believe.
on the bottom of the iphone is the speaker assembly. Attached to that are 4 prongs that touch a metal plate when it slides in. Make sure those prongs are connected to that metal. If they are not fold up a piece of paper and slip in in between the gap from the speaker to the prong so the metal is touching that plate. BE CAREFUL with those prongs they are extremely fragile.
