In case people don’t know, the reason this was done is because, even if your phone is off, someone tapping into your phone can listen in on whatever is going on in the room through the microphone. So, essentially, we are all carrying bugs on us most of the time.
but you could just take your battery out...or is there some other little battery in there we don’t know about
I hope they listen in when I am in the bathroom after consuming hot wings and poppers.
