Why does my phone alarm go off without being set and makes calls on its own?

[iMore Question]

Phone alarm goes off without being set and makes call on its own.

My iphone 5s went off in the middle of the night -- it showed a time set in the "Timer" section that I never set. When I turned it off I heard a voice coming from the phone -- it had also dialed a number -- luckily it was to a business so it was a recording that was playing. I disconnected from the call and pressed the power button briefly to turn off the screen and went back to bed. Battery charge was showing 53%. No further activity with the phone but when I woke up six hours later, the phone was completely dead. Plugged it in and now it is asking for my Apple ID password (which I have not entered yet). I'm wondering if it got hacked or what might have happened to it. (The only app I have that didn't come with the phone is one that scans QR codes -- I have no non-factory apps.)

I don't know, but if it were me, I'd put the device in DFU mode and then restore it via iTunes. Afterwards, I'd set it up as new and passcode protect it.
