I was just on a phone call with my mom and I heard weird beeping on the line. I’ve never heard this before. It sounded sort of like interference that you would hear on a radio from truckers or something. My mom didn’t hear it the first time that it happened. And then it happened again and then she didn’t hear it and then she finally heard it the third time and we heard a woman’s voice I’m so confused right now. I have an iPhone 12 and it gets really hot and sometimes it shuts down out of nowhere. Could my phone be hacked?
