Has anyone else been experiencing reduced signal strength from their previous phones? I'm on Verizon. I came from an iPhone 4 and it got way better signal than my GS4. I live in a deadzone and the only place I really get consistent service (judging from my iPhone) is upstairs next to a window. When I used my iPhone I could consistently count in 1-2 bars in that spot, allowing me to make calls decently and send text messages with no problem. With my GS4, in the exact same spot, it floats between 0 and 1 bars. I can hardly make/receive phone calls--sometimes people call me and my phone doesn't even ring--and sending text messages is a nightmare because 9 out of 10 times it will fail to send at least once (usually I have to try 2-3 times just to send ONE message). In high traffic urban areas, I got 5 bars no problem with my iPhone. Now I can only get 3-4 bars max... I don't think I've ever gotten full bars with the GS4. I got it a month and a half ago so I can't return it. Is anyone else seeing the same kind of reduced signal strength or could my phone just have a defective antenna?
