since i am waiting for my two purchased Librem 5 phones i have to live with the spy in my pocket - android smartphone. I found the solution for now, its called Nope sound blocker and sticker magnet for camera protection. I already bought some of them and waiting to be delivered but i dont know how they work and if hackers can find the solution to bypass this mic protection. On my smartphone i do have double software protection for camera and microphone but still they can be bypassed somehow if the app is crashed.
Has anyone tested this sound blockers on smartphones and if they really work and protect the user?
