I like mine although I still dislike the touch wiz interface and all the bloat ware that you cant remove. Tempted to root and use clean lollipop. Fixed some of the niggles by using 3rd party launcher.
Battery life is acceptable, easily lasts 24 hours unless you are constantly using it. Charges very fast and can be done wireless.
Sound isn’t as good as the HTC m9 and the screen dpi is pointlessly huge (one of the main reasons imo for the battery life not being as good as it could be).
Camera is brilliant but jpeg processing is a bit heavy-handed. Hopefully they will add raw support in updates.
Very powerful, not noticed any slow downs or system hangs.
