If for some inexplicable reason you own an Apple device and haven’t already disabled FaceTime, you should do so now:
Users have discovered a bug in Apple’s FaceTime video-calling application that allows you to hear audio from a person you’re calling before they accept the call—a critical bug that could potentially be used as a tool by malicious users to invade the privacy of others.
You don’t want a caller to hear you bitching them out for being inconsiderate by calling you instead of having the decency to send a text message.
