Let's face it the S3 is an great divice but signal issues on this phone are making me regret my purchase. Both my wife and I have S3 and we keep losing Network & Wifi signal. Places where my previous phone used to work S3 can't get reception. I have already done factory reset to no avail. Next option is to switch device however, I don't want to do that then end up with something with other issues like lose buttons and dust under screen. Is anyone else having signal issues on T-Mobile?
