Just unboxed my 5S this evening, and after setting up the Touch ID sensor I am wondering is mine working as it should? So the phone screen is locked - in order to unlock the phone. Is it supposed to work by me just putting my finger on the home button/sensor and it starting up by itself and unlocking? Or do I have to physically push the home button in? Currently, I have to physically push the button in but then at times it won't unlock it but instead launches Siri.. Is there a certain way to push/press the Home button in to actually unlock it instead of launching Siri? Or a specific amount of time I am to hold my finger on the home button? I've also encountered quite a few times where iOS 7 would crash on me and just go back to the home screen after being in Settings.. Anyone else experience this? Thanks!
