I use 3D touch on my phone icon to access some of my favorites. I have noticed lately that once I authenticate and I am on my home screen and I 3D touch on any icon, I will not get the submenu but instead get the ability to move apps around the home screen. Even if I wait a second or two to 3D touch. Try authenticating, swiping up and then 3D touching an app. Does it happen to you? This is not a big deal, just curious Edit: Just to be clear. This only happens when I immediately 3D touch after unlocking or within 1-2 seconds of unlocking.
