You should definitely consider changing the screen because you will have to open this phone up anyway to inspect what is going on inside. Not having seen your phone, many cracked screens start having glass chips and dust that can fall out or in some cases fall inside the phone. The vibrator is a mechanical device so that may cause some issues. I don't really see a link with the microphone though.

However, because the screen is cracked, it seems fair to assume that the phone has suffered some drops and under certain circumstances cause logic board issues. So [guide|29867|open] it up and take a look around and report back with your findings.
