i recently purchased a beautiful LG nexus 4. I was happy with my purchase but not for a long time. In the building where i am working , my phone has no reception at all. I went back to the store and i got a replacement phone since i was under the 14 Days return/exchange policy. The nightmare just continued ! I would understand that indoor the reception can be disturbed by many things , but i used to have an Iphone which was working great. Adding to that, on of my colleague has the exact same phone with Rogers and he has no reception issue . How can we explain that ?
