Ok I have a really weird issue. Starting a few days ago people on my contact list asked me why I called them. I was extremely confused because I never called them. I looked at my recent calls and there were no outgoing calls. So today about 3 different people told me that I called them. But like I said I never did. I had my phone locked for the majority of the day, so I couldn't have accidentally called them knowingly. I now have my phone on airplane mode and i'm going to see if people are still getting calls from me. If they are then does that mean my phone number is hijacked? But lets say that I turn airplane mode on and the calls stop, then I know there is something wrong with my phone. But I don't understand what could be causing it to do this. The only thing that I have changed with my phone is my case. I noticed the calling occurred after I put on a very bulky case for the first time (Griffin Survivor). But I really don't see how putting on a case would cause the phone to call people. I have updated my carrier settings and I'm gonna see if there is an available software update. But if that doesn't solve the problem, what will? I'm not sure if I should speak to Apple, or my carrier, Rogers (Canada). Any help or suggestions would be appreciated.
