sometime i even turn of mic and cam acsess on my phone

I have some bad news for you. Whatever software switch your phone has to "turn off" the mic, can still be bypassed by either the manufacturer or an attacker that gets root control of the device.

The only way to ensure a mic isn't listening is by either unsoldering it or shorting the + and - contacts. I mean in the case of a phone you can probably do the toothpick thing and then test it and repeat until sound actually quiets, but note that phones can actually listen to you by via the accelerometer :/

Open it up and break it off.

I had a similar incident with a cheap, 360, cam I bought off of Aliexpress. It was not going to be a security cam, just a cam to keep an eye on some seedlings in a grow box. I set it all up and would review the video of the seedlings sprouting. Then I noticed an weird behavior. At 5:00 AM it would automatically pan and stop, then repeat.

At the time we were experiencing some heavy electrical storms in our area and I have a Woody doll that sits up on a shelf in my lab. When we get electrical storms in this area, my Woody doll will introduce himself all on his own. 'Hey howdy hey! My name's Woody!' It'll freak you out if you didn't know it does that. The Woody doll has a pull string voicebox and I haven't pulled the string in years. I attribute the phenomenon to static charges in the air that activate the voicebox somehow.

So the panning I attributed to this static electrical charge during electrical storms. However, it started becoming a schedule. At 5:00 AM~ it would begin panning. So I got into the guts of the cam and the software. Turns out, no matter what DNS you used, one was already hard coded (1.2.4.8) along with other network settings, into the firmware and seemed to bypass any setting you punched in. The cam operated as a normal cam would and for what I was using it for, it did the job, except for the early morning panning.

So, great, I've allowed a nefarious actor into my network. I removed the cam off the wifi, and destroyed it. Combed through the network for any signs of exfiltration or other angles of attack and found nothing, except that I had pretty much set up a cheap, Trojan horse on my network.

Unsolder and replace with a dummy load. If the device requires an app from the manufacturer, uninstall it and throw the lamps away.

So, is there an easier way to completely disable the microphone?

First take it apart and determine what form factor the microphone is.

Is it a through hole microphone with two pins that are soldered to the underside like this? If so it's best to desolder it to prevent damaging the PCB. Use a soldering iron to heat up the pins and pull it out with pliers from the other side. If you don't have a soldering iron and don't want to buy one, I've also seen people using side cutters to cut off the solder joints and loosening the component enough for it to be pulled out through brute force without breaking the circuit board. If you can't or don't want to do either of those and don't mind risking the device, you could just yank it out with pliers like you're an old timey dentist pulling teeth, and hope that the pins break before the board does, might also help to twist it back and fourth repeatedly until the metal gets fatigued and break.

It might also be a surface mount microphone that, as the name suggests, is only soldered to the surface of the PCB. Might look something like this. These are pretty challenging for most people to desolder especially if it's close to other components, but they're small enough that the solder pads don't need a lot of force to break, so if you can get a good grip with pliers you should be able to just rip it off. Twist it until you feel the solder joints snap and then pull straight up. It doesn't really matter if you rip the pad off the circuit board since you don't plan on soldering anything else to it. But what you do need to be careful of is if you peel off more of the copper traces than just the pad, which can damage other components. If you do want to desolder it, touch the soldering iron to the metal casing which should hopefully heat up the entire component enough to melt all the solder joints, then pull it off with pliers. Just be careful not to touch any nearby components with the soldering iron.

Failing all those, you could also take a screwdriver or awl, put the pointy end on the microphone, and hammer it a few times to cave the metal casing in and hopefully crush the audio sensing parts. This will probably destroy the microphone, but less certain than removing it.

I've also heard recommendations about grounding the microphone connections after removal for extra privacy, mainly to prevent the traces from picking up EM waves, but I don't know how to reliably do that without breaking stuff so can't give any advice.

Does putting tape over it completely mute it?

No. Speech is surprisingly robust from an audio perspective and it's entirely possible for audio not recognizable to humans as speech to still be decoded by speech recognition AI. The thing is even if this works 90% of the time and makes the audio completely unusable, you can never prove if your case is in that 10% where there's juuust enough information for AI to detect. You also can't easily hear the actual output of the microphone so for all you know it might be fully intelligible and just muffled. If you're concerned about privacy to the point where you're asking how to remove a microphone, I doubt you'll accept that 10% chance anyway and removing the microphone entirely will save you a lot of anxiety.

I am a bit confused. How is the manufacturer listening on you? Do you have that connected to your WiFi or Bluetooth? Both should be easy to handle.

Best way is to test it. Get the voice commands to work. Then non-destructively block the mic. Does tape stop it from working? No? Try sticky tac or playdoh or chewing gum. Does that stop it? Yes? Maybe try something more permenant like hot glue or superglue. Then verify it still doesn't work.

In a pinch, some superglue liberally applied can either block reception or muffle it so much that anything it could send would be largely useless. Or you can open it up and remove it and hope nothing else breaks in the process.

Disconnect it from internet and bluetooth
