I am currently using the HTC Rezound which is an android phone and its never given problems until now. My phone shows that I have both mobile network connection and WiFi connection but I cannot make phone calls. I can still access the internet but when I type in a phone number and hit the big green call button a million times, nothing happens. Not only that but when I receive or send a text message it has about a 2 hour delay. Obviously this seems like network issues but it just doesn't make sense because in my status bar shows i have connection. If nobody here knows a solution can you explain to me how to reboot my android without losing my data and memory. Assistance would be greatly appreciated.
