On the software side - I like that it has a protected mode based on fingerprint access. You can have separate photos, etc.
You can also (with one click) turn over your phone to a child and they only have access to apps you've designated - nothing else.
Yeah hopefully we get that with touch id. The Verge wasn't too impressed with the scanner though:
Less successful is Samsungs take on the fingerprint-unlock system made popular by Apple with the iPhone 5S. Like the 5S, the S5s home key features an integrated fingerprint scanner, which can be used to unlock the phone or authenticate purchases online (Samsung is partnering with PayPal to enable this feature, though it doesnt validate purchases from the Google Play Store). Samsungs version requires a vertical swipe over the home button to activate the scanner, and we found it to be quite unreliable and virtually impossible to activate when holding the phone in one hand. It can store up to three different digits, but it was very particular about the speed and orientation of the swiping motion used if we werent doing a perfectly straight swipe down, it would refuse to unlock the phone.
