Google started taking user information security even more serious with the launch of Android 6 Marshmallow. They built on that success with the Nougat 7.0 that would also allow the user dictate which permissions an application could have.
With the launch of the latest dessert on the table – the Android 8 Oreo – came even better restrictions that could allow you stop your cameras from working in the background. If that is not enough, it is rumoured that Android P (the next dessert in the series) will offer even much more.
Users of Android devices have, over time, complained that their microphones might be compromised. Some believe strongly that the mics on android phones can be accessed remotely and used to get information around said device.
The truth behind that has not been proved by anyone till date. However, for Google to see this as an important addition to the coming software, there must be an element of truth to such claims.
For times when you are not using applications that require mic access, Android P will step in and block them from recording sound. If there were truly anyone listening in on our conversations when our devices were idle, take that!
