Design

The Samsung Galaxy Note 4 is Samsung's best ever built smartphone. The Note 4 is crafted out of shiny aluminium and a soft touch fake leather. The shiny aluminium sides are very slippery but they do add a nice touch to the phone. The fake leather back is far from amazing but does the job. On the bright side the back is removable, so you can swap in and out the poor battery. The Note 4 has Gorilla Glass 3 to help protect its beautiful 5.7" display from cracking.  Altogether the Samsung Galaxy Note 4 is a well built phone.

Software
