So i just looked around and found mine has it on a panel/tab to the side.

Yeah, idk, they probably do. What can you do though?

Best to just assume anything and everything done with a phone is potentially documented elsewhere, and if you're REALLY paranoid(this last bit is too far for me, i gotrata have a fucking life at some point lol) pull the battery out and smother the phone so the mic can't detect anything(some phones can even still hold a charge and operate with the battery removed, so the most paranoid thing would be to pull the battery out, and keep the phone a distance from you, or buried under pillows or your own ass)
