[Q] Signal issues with my S3

view story

http://forum.xda-developers.com – So my and my girlfriend switched both from Droid X's back in September, with that said we never had any issue with signal at our house(all ways had full bars 3G). Soon as i came home with my S3 i noticed that both of our phones had poor signal strength 3G 1 bar or 1x. I called verizon tech support they had no idea what was going on and were wanting to replace my phone, saying my phone was the issue. However my Girlfriends S3 was having the same problem now i don't think that both phones are defective and the tech rep was wanted to replace my phone with w refurbished one which i just bought thi (HowTos)
