I just got the S4 yesterday, and I have been having problems with my wi-fi connection. It indicates that I have a strong connection, yet it takes for ever to download, it actually is faster to turn off the wi-fi. Even google play takes a long time to load (with wi-fi) turned on. One thing I noticed is that even though I am connected to a wi-fi, the phone is constantly scanning for a wi-fi network every 5 seconds (I see this in the Wi-Fi settings), and think this may be causing my problem. Is there a way to turn it off. Are others seeing any issues with the wi-fi?
