Try cleaning the iphone connector at bottom of phone. Use cardboard and insert into connector. If you look inside you can see a little divider, clean on both sides of this carefully and gently by sliding the cardboard back and forth. Gently tap phone and see if some dirt falls out. You may have to do this a few times. Also, check iPHONE : SETTINGS/SOUNDS - once in SOUNDS, scroll down to bottom to LOCK SOUNDS and KEYBOARD CLICKS make sure both are ON (green showing) if you are missing the camera click sounds and keyboard sounds while typing. Worked for me and I got close to chucking phone in the bin!
