So I was reading through Kindle app and out of nowhere the screen changed to calling my voicemail which it immediately hung up the I received a service message saying that the action could not be completed due to not being registered to any network. For about a minute I couldn't make any calls or use data then it went back to my normal provider. I use qlink wireless and never have had this happen before. Is my phone hacked? How do I stop this from happening again and how do I figure out if my phone has some bug to control it? I have lookout as a antivirus but it's just the simple one not premium subscription.
