iPhone problem

A few weeks ago, I'm facing problem with my iPhone home button. Having difficulties in pressing it. So my husband says getting a button sticker will ease the problem.

Tried finding them at those neighborhood hp shop but find them either too fancy or too cute for me. Then went G Market to look for it. Finally found a simple set and costed S$1.20.

Anyway I also on my iPhone Assistive Touch under General and Accessibility so that I can rely less on the home button. So iPhone users do you also face the same problem as me? Cheers.
