Canceling the microphone requires closing the lid of the iPad Pro and is only available on new models, which include this chip. As with the new 2019 MacBook Pro, the security and privacy Thanks to this chip it increases considerably.
All MFI cases support this feature
And it is about close the lid with a case and in this step all you need is a compatible accessory that is Apple MFI certified. This certification is added by several products that we have in the market and among them those that Apple sells on its own website of brands such as Logitech, Simmetry, Dux, etc., in addition obviously to the company's own.
We can say that this is a direct way of keeping people's privacy safe in a direct way and is that once the iPad lid is closed, the microphone is disconnected by hardware, making it impossible to activate it remotely. The company could apply this security function to the rest of the equipment that they present in the future, and that is that the iPad's camera is completely covered with the current covers, making it impossible for it to “see” something of what we are doing. when the device is not in use.
