Why does my iPhone 5s home button feel weird?

So I've had my iPhone 5s for about 2 months now, and it works perfectly fine. Only problem I have is that I feel as if the home button is not working properly. It feels unsteady and weird. When I push it down, it feels as if you have to sort of force it. Does anyone else have this problem?

Try to replace a new home button? The repair guide you can found at youtube.

the replacement parts you can buy it at witrigs.com for less than 6$ and they provide different color.
