Hey everyone, I got my GS4 about a month and a half ago, having switched from the iPhone 4. I live in a deadzone, and the only place I really get any signal is upstairs next to a window. When I had my iPhone (used it for 18 months), in that one spot I could make calls decently and send and receive messages. With the GS4, I can barely get a call in without saying "mobile network not found", and I can seldom send text messages without it failing to send at least once per try. With my iPhone I could count on 1-2 bars consistently, but with the GS4 I float between no service at all and 1 fuzzy bar in the exact same area. In fact, doing a side by side comparison right this moment, my iPhone has had 2 bars while the GS4 struggles between 0 and 1. Another thing I realized is that in high traffic urban areas, where there are strong signals, I only get 3-4 bars while with the iPhone I could easily get 5. I don't think I've ever seen my GS4 with full bars. Does anyone else experience reduced signal strength with the GS4 after switching from other phones? Could mine just be defective?
