A:Answer Yes, the lock works and when you have a call you simply answer it with one touch. As far as the lock is concerned, if it's not you, your not getting into your phone without your code. Period. The cloud keeps all your important data and when I updated my 5 to the 5s it worked seamlessly. Plus my 1st iPhone lasted for 3 years... The battery started to fade and best buy had an awesome trade in deal! Trust me, if your tired of screwing around with a phone the doesn't work, locks up or is aggravating to use, move up to the iPhone, you won't regret it.
