Was this a problem on the first Note tablet? As I get to installing a lot of apps, over 500 is what I have, I've found that the tablet is going through an infinite boot loop. I'm talking to a Samsung rep online now about it. I've tried taking out the sd card, putting it back it, etc. It appears that some are going through this too with the Galaxy Note 3.
Updating my status. Through my own research, instead of trying to install all 500 at once, I've taken a more modest approach. I'm installing apps 4 at a time, letting it finish, powering down, then starting back up. It's working. I can get to my home screen without problem now. Maybe 500+ apps was too much of a strain for the file system to endure.
