Can a hacker monitor my phone?

Yes, a hacker can absolutely monitor your phone by installing spyware, using phishing, exploiting vulnerabilities with advanced tools, or via techniques like SIM swapping, gaining access to your calls, messages, location, camera, and personal data, though sophisticated remote takeover often requires physical access or expensive exploits.

Does turning off your phone stop hackers?

Yes, turning off your phone temporarily stops most hacking, especially remote attacks, by cutting active connections, but it's not a permanent fix; hidden malware or backdoors can reactivate on restart, so frequent reboots (like weekly) help disrupt sophisticated threats, including zero-click exploits, but aren't foolproof against physical access or advanced persistent threats.

Should I cover my phone's camera?

You can cover your phone camera for extra privacy against hackers, but it's often seen as excessive paranoia, and you'll lose photo/video functionality unless you use a slider; however, standard phone lenses are durable, so lens protectors aren't needed for physical damage, and focusing on preventing malware (strong passwords, no suspicious links) offers better security than just covering the lens, as microphones and other sensors are also risks.

Does changing your password stop hackers?

Yes, changing your password does help stop hackers by limiting their access time and disrupting their efforts, especially after a suspected breach or data leak, but it's most effective when combined with using strong, unique passwords for every site and enabling Multi-Factor Authentication (MFA), as hackers can still bypass a single password with phishing or malware. Regular changes help, but strength and uniqueness are key to preventing credential stuffing attacks, and MFA is a crucial second layer of defense.
