Alarm freezes phone + more
I have an iPhone 5 running iOS 9.0.2. Out of nowhere, the phone started to act up: when my alarm goes off, it will only vibrate even though I have a song assigned to the alarm, and I can't unlock the phone because neither the power button nor the lock button light up the screen to the lock screen, forcing me to restart my phone with the home button and power button. On top of that, I'm no longer receiving messages or phone calls. iMessage works, but I'm not getting messages sent to my number, and I get voicemails without the phone ever ringing. This all started happening after I put torrented music on my phone.
I've already tried restarting my phone, resetting my Network Settings, and switching iMessage on and off. What should I do?
