Missed FaceTime call that I never made
My friend got 6 missed FaceTime calls from my number in the mid-night when I was sleeping (every hour from 2-8am). I never made those call and no FaceTime record on my phone. I wonder if my phone or his phone got hacked.
I checked and no email notification saying that my Apple account logged in to any new device. anything else I should do to ensure my phone or my Apple ID are safe?
thanks
