I have had my phone since August 2013 and in the last couple months I am unable to receive emails or notifications while my phone is connected to WiFi. I reboot my phone often and have tried resetting it. Nothing has worked. If I do not connect to WiFi there are many things my phone will NOT do certain things or it slows down tremendously. This isn't just a problem with my home WiFi, this happens anywhere I use WiFi. Does anyone have any ideas or suggestions?
