No (Score: 1, Interesting) by Anonymous Coward on 2016-09-08 15:57 (#1T2R5) Because I actually take video and use video chatting apps and I have yet to find a cover that's convenient and will work with my choice of phone case. (It was a gift, I love it. I'm not changing cases if the new one doesn't offer a significant advantage.)Besides, the microphone scares me more. No one's going to blink if some idiot hacks photos of me staring at my phone in the bathroom. If they hear me say the wrong thing, though, I could lose my job.So far the only real security I've seen was an idea pitched for a phone case which alerted the user if the phone became untrustworthy and started sending signals without permission. AFAIK that idea has not yet become reality.Anybody got a pitch for something that blocks the phone's mic AND camera?

I can't imagine an external device that would be able to work out the difference between desired and undesired signals from your phone.

The two requirements are sufficient coverage (a mesh can be used, but the maximum spacing is related to the frequency being blocked) and sufficient thickness, to ensure eddy currents can't radiate from the outside.https://en.wikipedia.org/wiki/Faraday_cage
