Wifi Connection/Icon Disagreement
While the Wifi is connected in Settings (with a check), the small icon (top left) never appears. When opening up Safari or email, I receive a warning to turn on Wifi or cellular. Knowing that Wifi is connected, I select OK and can surf. Same message for opening email and can read and reply as though connected. My cellular data usage is running up and appears that the phone would prefer to use cellular vs wifi.
