Phone repair .. phone is now faulty

[AC Question]

I dropped my LG G3 and cracked the screen. Everything was working except for the very right hand column where the crack was and the touch was not working. Took into a mobile phone repair shop where they fitted a new full LCD Screen Display+Touch Digitizer Assembly. Now the phone has come back and the swipe to unlock/knock code does not work nor the headphone jack.

I know that the headphone jack has to be removed to install the new screen etc so am confident I can say that is him. Would the swipe/knock touch (sorry not very technical) be a fault from the new part or is this controlled from the phone itself?

Welcome to Android Central! Are there any other abnormalities in how the screen sense your touch after the repair? If things seem less sensitive, then it might be due to the part that was installed.
