Smartphones have lock-screens that usually require some swiping gesture to unlock. This is so the capacitative screen doesn’t accidentally unlock in your pocket. These lockscreens come in all shapes and sizes; some reqiure swiping left to right, others upwards. A trend started by, I think, Windows Mobile, allows you to swipe-unlock directly into an app. For example, you receive a text message, turn on your phone, see there’s a new message and swipe towards the messaging app to read it.

But what about security? Your smartphone holds your entire digital life. Should your phone be snatched in a bar, the hardware itself might not be the only thing you get stolen — your Google account perhaps being a more severe loss than the $500 phone. Which is why you should have some sort of security code as your lock screen, no matter if that’s a number code or a security pattern.
The short of it is, everyone should go through this hassle to unlock their phones, at which point the fanciness of swiping directly into an app is lost. Would the time spent working on hi-tech lockscreens be better spent improving the homescreen? I’d say so.
