Really? You can shoot 4k video on your phone? You have a multi window app where you can run two apps at the same time on your screen? You can create a slideshow, photo collage, story album and video clip all from your gallery? You can pull down from the top bezel in any fullscreen app to view and interact with the notification bar? (Not even a feature in AOSP) You have a finder feature that lets you search for anything on your phone (pics, videos, notes, messages etc..) just by typing a single word? Your phone can do one handed operation by shrinking the screen down and moving it wherever you want on your display to make it easier to use? Your phone has a call notification window? You can copy a number and paste it in your dialer? (I can't on my Moto X running stock Android) I'll stop there, I won't even go into all the useful features with the S pen you'll never see on another phone. I could go on for days with features I have on my Note 3 you probably don't even know about and features that don't exist in any app on Playstore. But again, have fun with your stock phone
4k video - didn't buy the phone for its camera.
Multi-window - screen's too small for that, and I prefer one handed operation over a glorified app switcher.
Photo gallery operations - yep, apps are available for that.
Full-screen notification bar - yes...that was always there.
Searching - yep, apps are available for that.
One-handed operation - it's naturally able to do that.
Call notification window - ..what? Yes?
Copying and pasting numbers - yes, don't know why you can't.
So basically you looked at all of the minor details and you went off to tout them as critical features. Call notification window? Photo gallery slideshow? Really? Practically all of those things are available through apps. I didn't buy a phone with a stylus because (gasp) I don't want a stylus! Crazy, right? You even went as far as saying the one-handed thing is a feature; that's not a feature, that's an issue the phone's form factor introduced and thus they had to figure out how to make it usable by human hands. I don't see how you can possibly brag about that.
But again, have fun with 4.3 for another 5 months. (4.4's probably going to be the last update you'll ever see, too! Whenever it comes, that is.)
