The slow charging doesn't bother me,specially that kernels are out at XDA for fast charging,though what I hate about this phone are the fact that its very prone to chipping and scratching if you don't use a full on cover like double flip,also the camera is just ok for daylight and very buggy for low light (blue tint and slow shutter) which is a pitty when you know they advertise everything on this..
The design is very cool but you get bored of it after 2 months,the UI and the screen are the only thing excellent about it.
I like the S4 but the poor sunlight legibility and perhaps not as good sound quality (over earphones) are keeping me away of it
Most people get bored with their phones after 2 months because the "newness" has worn off......just sayin'.
