This and the sound 'issue' are the only things about this phone that are really bothering me. My wife's phone doesn't have this issue with the lockscreen, though it's kinda laggy in general. Probably 80% of the time, when I wake my phone, the lockscreen hangs for a couple of seconds before I can do anything. The little "T-Mobile" near the top right isn't there at first, then after a couple of seconds it shows up and lets me know I can unlock it. It will register my swipe, but won't do anything until that point. It's a small nuisance, but one nonetheless, and sometimes takes a good 3-4 seconds. I've tried various wallpapers, getting rid of some apps, etc., and it still does it. I haven't factory reset, and would like to avoid that as I'm not sure how that'll affect root access. Anybody else seeing this or having this issue?
