I already have a samsung S4, and frankly this mobile does not have to fade from office. While it is slightly less sensitive and the definition of the screen is slightly less clear but it serves its 100% taff. You can download full of apps and the SD card allows for a great deal of storage. Fortunately there has qqls these differences cited with S4 or I would have been very upset with the acquisition of my samsung. Every day I used exactly the same way as my S4, so do not be afraid to take the plunge by buying this mobile.
