Microwave/ferriday bags are fine. But they do not prevent the microphone from working. Sound waves will still go through a bag. And if the phone is compromised which we’re assuming it is in this model, then the phone can just record the audio and wait for a network signal to upload it later
But if you’re in a hurry. Put whatever you need in water. Water is an excellent conductor. Usually. So if you put something in water it’ll have a very hard time transmitting radio waves through it. If you want to preserve some electronics put them in a bag first.
