Verizon needs to approve the 5.1.1 update. Sprint's Note 4 users have had it for almost a month. T-Mobile users now have it as well. (Rumors are, by the way, that their update makes their phone feel like new.)
My biggest issue is lagging (especially the Recents menu). I've factory reset and that doesn't fix it. I'm afraid only the 5.1.1 update will fix that. There's nothing but positive comments about 5.1.1, and we're still here waiting on Verizon to push 5.1.1.
I know you'll reply with your Twitter handle, but your responses there aren't any better.
