Microphone Blocker is an Android application designed to enhance privacy by preventing unauthorized access to the device's microphone and camera. It addresses common concerns about apps secretly recording audio or capturing video without user knowledge. The app works by intercepting and blocking access requests, and it provides a clear, detailed list of all applications that have permissions to use these hardware components. This feature is particularly useful in real-world scenarios, such as when downloading new apps or auditing device security after a reformat, as it reveals often-overlooked permissions that could compromise privacy. User reviews highlight its smooth performance compared to similar tools, with many noting how it uncovered surprising levels of access they weren't aware of. However, some limitations exist; for instance, users report difficulty in testing whether the blocking is entirely foolproof against sophisticated threats, and while the free version covers core functionality, advanced features may require an upgrade. Despite this, Microphone Blocker remains a practical choice for everyday privacy management, offering a balance of usability and security awareness.

As a retired IT security professional, I was stunned by how many apps had microphone access without my knowledge. This app made it simple to block them and see exactly what was happening, and it runs much smoother than others I've tried.
