Static noise from phone when not in use.
Lately I have been noticing my iPhone 12 Pro Max making a strange static noise randomly when I’m not using it. I’ve checked to make sure I was signed out of YouTube, music, Internet, etc. and that was not the problem. I woke up at 3:20 this morning because I could hear a light static noise coming from somewhere…. so picked up my phone and put it to my ear and realised that it was coming from the speaker on my phone. I think this is very strange….. Its very concerning and makes me feel uncomfortable. Does anyone know why this is happening, or what it means? Is someone listening in on me and my family? Is my phone tapped? Please help! Thanks
