I am having problems when I call people. Every time I try to make a call to someone I can hear the ringback tone, but as soon as someone picks up the phone or their voice mail activates my phone will automatically hang itself up. I'm not sure what should I do. I thought that factory resetting my phone would work but I don't want to risk losing all of my information that I have stored in my phone.
Is there any possible solution to my problem?
