Do not install applications of unknown origin at will, especially those downloaded from the unofficial application market. Don't click on unknown links in SMS, email, social media and other channels at will. Use safe and reliable antivirus software and update the virus database regularly. Avoid using Bluetooth, Wi-Fi and other wireless connection methods to connect devices or networks from unknown sources.

Avoid connecting to public Wi-Fi networks at will in public places, especially those without password protection. In mobile phone settings, turn off unnecessary application permissions, such as accessing sensitive permissions such as address book, camera and microphone. Update the mobile phone operating system and applications in time to fix known security vulnerabilities.
