What Micro Guard is for
Micro Guard is a Tools app from Protectstar Inc. The developer describes it as a microphone blocker that helps stop apps and spyware from listening through the phone's mic. It is for people who want more control over which apps can record audio on their Android device.
The app does not replace the system's own mic settings. It adds a separate layer that the developer says can block access while protection is active.
Turning off the mic and choosing which apps can use it
A single tap turns microphone protection on. Once it is on, you choose which apps are allowed to use the mic, so every other app is kept out.
For times when you do not need the mic at all, Mic Off mode switches it off. The developer says this reduces unwanted background access by apps that would otherwise pick up audio without you noticing.
Reviewing mic access attempts and alerts
While protection is active, Micro Guard records each access attempt in a logbook. You can look back through it to see which app tried to use the microphone and when.
The app also alerts you when it detects suspicious behavior. The developer does not describe what counts as suspicious, so the alerts are only as clear as the logbook entries they point to.
How the controls fit together day to day
The typical flow is to turn protection on, set the list of apps allowed to use the mic, and switch to Mic Off mode when recording is not needed. The logbook then shows any attempts that were made while protection was running.
Protectstar Inc. lists the app under Tools, and its store summary sums it up as one-tap mic off, app control, logs and alerts.
