Anyone else in the same boat? I've never been one to use a passcode, just don't like the inconvenience even though I recognize it's a good idea to do so. Now with the finger scanner, I figured I could finally lock my phone and not be inconvenienced, so for the first couple days of using the 5S, I left the feature on. Unfortunately it's still a pain in the butt. Sometimes it seems to work instantly, which is great, but other times I sit there repositioning my thumb to get it to rear. Usually it works, I'd say 9/10 times, but sometimes not at all and I end up putting in the code manually. That's not even so bad...what really bothers me is when you have a missed call or you get a text. Im used to just swiping from the lock screen and going straight into the call or message...but with the lock code, if you swipe, it brings up the passcode input screen and then you have to hold your finger there. Guess it's just not for me, which is a shame as I like the idea. On that note, I wis you could set the scanner to be used for App purchases but not for the lockscreen (and I mean no lockscreen code at all).
