Probably around once every 50 or so times I use the home button to wake my iPhone it either doesn't wake the phone up at all and I have to press it a second or third time, or it takes 3-4 seconds to wake the phone up. The time delay makes me wonder if this is actually a software problem vs hardware problem with the phone, but it reminds me of the home button problem I had with my iPhone 4 years ago where you had to hit the home button multiple times to wake the device up. Apple replaced that phone for me. Anyone else seeing this problem? Thought I'd ping the community before I call Apple.
