So I've been installing lots of apps to my Atrix over the last 2 days and today it started getting serious lag and would become unresponsive to the point I couldnt bring up menus, switch apps or get into the lock screen with the fingerprint reader. I'll try to get a video if I can and I am going to try to hunt down which application is doing this. Just an FYI. So far I am looking at the Apps I've installed today since it did not do this all day yesterday or last night. I will update when I figure it out.
