Security With Cortana.

[Aayam Gupta]

Dont know if any of you know this but well i found this feature extremely useful. Enable Cortana from the lock screen and Call someone...rest of the features remain locked.
well sometimes my family members use my phone for calling other family members
and my brother who is very very annoying used to fidget with my settings and texts and whatnot! but with this I can give him the phone and he just cant unlock it without the passcode

You can dial numbers with cortana too right? so basically if you want to loan your phone to someone without them messing around you can just open up cortana
