My phone app keeps stopping. When I'm in voicemail or trying to look at my recent call logs it keeps kicking me out in 10 seconds with a message saying it unexpectedly stopped, and none of my missed calls or any calls for that matter will show up in the log. Also I'm not getting notifications when I receive a voicemail. When I go into settings for it, it keeps kicking me back out before I even have a chance to find what I'm looking for being it too is under the phone app. The phone app is what the phone came with, I didn't put a new one on
