Services are lazy-loaded, and scanning begins only when<br> the user starts a tool.</p> <h2> Important limitations </h2> <p>A smartphone cannot guarantee that it has found every camera, tracker,<br> bug or network threat. Several detections are heuristic and may produce<br> false positives or miss threats. Hardware availability also differs<br> between Android devices.</p> <p>The project is intended only for education, defensive security and<br> testing devices or networks you own or are authorized to assess.</p> <h2> Feedback wanted </h2> <p>I am looking for:</p> <ul> <li>Compatibility reports from different Android phones</li> <li>Feedback about permission handling</li> <li>False-positive reports</li> <li>Contributions, tests and documentation improvements</li> </ul> <p>Repository:<br> <a href="https://github.com/theabhishekchandra/ZeroDroid" rel="noopener noreferrer">https://github.com/theabhishekchandra/ZeroDroid</a></p> android kotlin opensource showdev
