Why there's a clicking sound on my iphone 6 home button?

After the front screen protector was installed to my iphone 6 i hear a clicking sound when i half press the home button, i don't press it all the way down, just half press, i can hear a clicking sound. Why is that? Anyone please explain why.

That is only the CIA listening in. Just ignore it!

Mine just started doing it too. Not a big problem obviously, but it started after I dropped it and the screen protector cracked a tiny bit. Sometimes it gets stuck a little when it clicks and makes a double click and Siri thinks I have a question. So I asked her why my home button clicks and she brought me to this page!

  • Why does my car stereo make a clicking sound when I charge my iPhone? I just bought a certified preowned 2009 Mazda Mazda3 hatchback. Whenever I plug my charger into my iPhone while it's connected to the aux input I hear a repeating clicking sound through my speakers. The clicking gets faster and slightly higher in pitch as I push the accelerator. What's going on?
  • My iPhone 5 screen started making this clicking sound when pressed on? It sounds like the home button screen "pop" when clicked. It's on the top right and when it's pressed on it pops. If I take it to Apple will they replace it for free or give me a new one? I bought it through verizon and I'm not sure if I still have guarantee thing going on.
