[AC Question]

Okay, my LG G3 dropped from a chair onto tile and the bottom-right has an arcing hairline crack just barely cutting off the bottom-right corner of the screen. I have noticed that I cannot press the enter, backspace (for the keyboard), and it it hard to press the send or anything along the right side. My question is, what are all the parts i need to replace. Is it just that the glass corner is no longer connected , so all I would have to do is get new glass. Or is it the digitizer or even the LCD that I need to dig out.
