Truth is, I hadn't actually realized that our Maxx had the ability to slide from the unlock screen to camera or other widgets on the lock screen. Now, I realize it was foolish of me because my Gnex could do that but I have only been to the lock screen a few times since I've had my max. 98% of the time I unlock from the active notifications screen.
After seeing his review. I tried to recreate the lag multiple times. I had ZERO lag with every attempt. I'm not sure what was going on there.
