So it seems like something strange has happened with my phone. On the home screen, in the middle of the status bar, there is a padlock, not a clock. I have the phone plugged in, but the battery indicator is stuck and not showing that it's charging, and is stuck at 95%. I can't get internet, and I can't make phone calls. I have no idea what happened. This started maybe 20 minutes ago? I can't turn the phone off either.
