3-5 times a day I tend to grab my phone upside down with the home button at the top and I keep trying to unlock it lol. For some reason I guess subconcsiously I think that the home button is the / a speaker and I keep trying to do this.
I had that case about 3 times with my iphone, but that was when i wasn't having any protection box for the phone, now that i have the phone inside mophie juice pack, i never face it anymore whether sleeping or not.
