Hello friends.  I just repaired my iPhone 6s, which had suffered a fall damage.  I changed the component with the Lightning connector, because it should be responsible for the sound problems caused by the fall with Siri and telephoning over the loudspeaker.  The same goes for the defective screen and the microphone it contains.  Nevertheless the sound of videos is only recorded with a strong noise (far away you can hear the sound in the background) and Siri only hears me when I call down into the phone.  But telephoning via the loudspeaker (FaceTime ect) works again) Which component is still broken in your opinion?

it could be the mic at the back of the phone, its located next to the flash light and is part of the power/volume button flex.
