Unresponsive Home button since iOS7 upgrade
Since upgrading to iOS 7, my iPhone's home button is often unresponsive when I want to exist an app. I have reset / re-calibrated the home button numerous times. The improvement is short-lived.
I have an iPhone 4. I suspect the issue is due to the phone's older, less-capable processor. My iPad 3 does not have the issue.
I was wondering if others are experiencing the same.
