I had some difficulty. First, I entered the same thumb in my phone twice. I also changed my reading thumb posture. I found that scans are much more reliable if I'm touching only just hard enough to maximize readable print area, but not actually push the button in at all. Maybe this is how it was intended and I didn't pick up on it at first. Pressing the home button in seems to reduce the readable print area, because it's a more deeply recessed pocket then.
