I recently recieved a refurbished phone to replace my broken phone. Ive noticed that when I'm connected to my network that it takes forever for Facebook to update. As soon as I disconnect from the network Facebook updates almost immediately. One thing I noticed on this phone is while its connected to WiFi, I get the 4g icon and the WiFi icon showing in the status bar. My wifes phone which is the same, only shows the WiFi icon when connected to the network. Its almost as if the two are competeing with each other. Any ideas?
