I upgrade my htc one to 4.4.2 yesterday and everything was fine. However, I did notice my lockscreen changed to a new one with the lock in the center and when pressed it there's ripples/circles around it. My phone died after awhile and when I went to restart it, the lockscreen reverted back the original where you swipe up to unlock. I was wondering if I can get that lockscreen back with the lock in the middle? I don't want to download another app to get it back, and surely it must be built in there somewhere..?
