I agree with the above poster Verizon's update has a few bug. stick with 4.4.4 for the moment. if you do decide to update - afterwards clear your cache or do just a straight up factory reset. You can do either - update through samsung kies or over a good wifi connection I believe kies would be faster.
I have two choices with this update.......1. Install OR 2. Install later. I chose install later but that only gives me the option to chose what hour you want to install it. I really want to stay with 4.4.4 but I soon won't have a choice. I also was thinking of doing the update thru Kies.
