If you use it without a case that covers the home button more than likely something off of your or someone else's hands had gotten under it or if you press it too hard one of the rocker pieces is cracked or broken it can be repaird or replaced if out of warranty for at round $100
I am and so is my sister and cousins. My cousins were told that it is a phone glitch. It is getting really annoying. I have not taken mine in because it doesn't do it all the time. It seems like every time I try to show someone it doesn't do it.
I'm glad that I'm not the only one. I got an Otter Box today and the button is acting a lot better. I'll have to see if it makes a different after some use.
Thanks.. I was wondering about that.. I bought an Otter box. I put it on today and the button is acting great again.. I'll have to see if it continues. One other use answered and said they had been told it was a glitch with the phone.. time will tell.. thanks for answering!
