So touch ID is nearly instant (100ms ?), great, but then after using instant touch ID to wake phone and enter the home screen, 3D touch is unresponsive. Suppose I do touch ID fast, and then 3D touch on camera for selfie, it doesn't work. You have to wait a bit (1000-2000ms). Sure a second or two isn't the end of the world, but if Apple took extra pains to make touch ID instant, why delay 3D touch which is designed for ultra-fast tasks such as shortcuts, selfies, etc? I think this is a major flaw because the 1-2 second delay is slow enough for me to actually skip 3D touch and open the app instead.
