Been using the phone all day today and performance has been MUCH better. Maybe because I'm pretty much done setting it up, downloading apps etc etc. Haven't had much lag at all today and am very happy with the performance today. One thing iPhone (6s+ in particular) users will need to get used to is the speed of this phone. It's not a speed demon by any means like the 6s+ is. If that's what you're hoping for then you'll most likely be disappointed. If you're looking for the additional functionality that Android and the Note provide then I think you'll be extremely happy once u get used to the performance of the Note.
