I have a nokia mural cell phone. Everything was working fine with it. When I opened my phone to make a call, my background was gone and all of my settings. Also, the phone will not let me go to menu, messages, music, internet, etc. It will only let me dial numbers and receive voicemails. I have tried taking the battery out and sim card. Nothing has worked. Like I said before, nothing happened. I closed my phone and when I reopened it, my settings were gone and nothing worked? Does anyone know whats going on?
