Just got my phone back from Samsung after they repaired it due to the Sudden death bug. As expected it was completely wiped and updated to 4.1.2. However now the wifi seems to be downloading regularly when I'm at home. I think I remember it doing this before, back when I first got it, and I turned something off, but I can't remember what. Another thread on here suggested Google+ likes to keep checking stuff and also that compatibility mode on the router for some phones affects it. So i'm gonna try those. Just wondering if anyone else on here has had this?
