So my replacement iPhone 4 clicks when I tap the right side of the screen. I took off my Wrapsol to make sure it wasn't the screen protector. After testing my dad's iPhone 4, I realized the screen or back plate of mine must've been loose. I immediately booked an appointment at the genius bar for tonight. So I go there and wait awhile for a genius to help me. One finally comes and he asks what the problem is. I explain it to him and he holds the phone and starts tapping it. He does hear the clicking sound and then hands it back to me. He says there will be a software fix coming soon. At this point, I was like "wait... what the heck are you talking about? It's a hardware problem" He claimed it was a software issue and told me not to worry about it. Since it was past 9pm at this point, I decided to not escalate this in some stupid way. I'm just going to call Applecare in the morning. Turns out some of these Apple geniuses aren't geniuses at all. Before someone says the clicking came from the speakers, I'm completely sure they did not.
