Hey guys. I was contemplating on buying a Galaxy S4 but it's a little too big and expensive for me and now I am contemplating the Galaxy S4 Mini. What are your opinions of the phone. How does it compares to the S4 in terms of performance and usability? And specifically, how is the Wifi range? I currently have a BB 9900 and it has poor wifi range. Wouldn't want a repeat. Oh and does anyone know if it will get Android kitkat? Need a future proof phone.
