Bypass Swipe to unlock in Android 5.0.2
You have set a custom VPN, encrypted your phone or something else that requires a lock screen on your phone. To disable that you will need to decrypt, remove your VPN's to get only a swipe lockscreen back.

On Android Lollipop, Google has added the swipe-up before you can enter your pattern. I don't know why the did that, but they found that usefull.

Hope my answer helps!
