So my Girlfriend has a Galaxy S2 with Sprint. She has constant signal issues no matter where she goes. This is her second phone because she lost/had her last one stolen. She had the same issues with the last one. Now she recently got the newest update. I would say a few weeks ago if not longer. Anyways, her dad has the same phone and experiences at least some of the same amount of signal loss as she does. Is there a fix for this at all or is this something that Sprint should swap her and her dad out for a different phone? It's just getting ridiculous. I'm on Verizon with the Bionic and I have no issues. I had Sprint before and with a lesser phone than hers I didn't have the issues with signal that they have. So it tells me it's not network but that it's the phone. Any help would be awesome.
