i am not 6+ owner but coming soon

, size should not be a problem to you if you are using note series.
As the past experience the annoying problem for me would be
1. Unable to manage photo and video nicely and neatly on iOS , can only delete photo from camera roll , others need to remove via itunes sync.
2. App are not able to access system level so makes sharing photo via gallery directly to whatsapp line wechat etc a bit hassle.
3. Background download limit 10 minutes , the screen need to be awake and on the app to continue the download.
4. No torrent

and a few more now cannot remember lol
What makes me back to iOS is the 6+ screen size , battery life and the experience

, experience in term of using the apps in iOS is truly awesome. Like reading the flipboard , facebook , wechat etc. Also invested alot in iOS app LOL
note 4 or go back to ios 6+. I used to share things across apps most of the time.. And quick note reminder at home screen..
