No it's glued to my hand... I sometimes shut off the screen and turn it back on up to 4 times in a minute... calculator app, checking my various fitness apps, email, text messages, web browsing, etc.
Having tried Touch ID for a few weeks it seems a better fit for me to use for iTunes/App Store purchases and I'm sure there will be apps in the future that will make good use of it. But to unlock the phone it's not a perfect solution... I turn my phone on and off too often and the failure rate of reading my fingerprint while better than most is still at 80% success rate for me. If I need to spend more time holding my finger on the button than it takes to swipe and type in my 4 digit password it doesn't work for me.
I'm not worried about "security" of my phone. I've had a top of the line mobile phone for well over a decade and I've never lost it, had it stolen or had anyone break into it. If I leave it somewhere longer than 5 minutes then the passcode comes on and nobody is unlocking it... the likelihood that someone will happen upon/steal my phone and turn it on in 5 min is as slim as me dropping my phone (and that is a near never situation for me)... and on top of that... Touch ID doesn't prevent one from shutting off my phone after they've taken it so I can't track it with Find my iPhone... the whole utility of Touch ID as a form of actual security is a farce. It's a slight deterrent; as useful as putting an orange cone in the middle of the road to stop drivers... most people will just drive around it or through it... if they can.
