Where is the firewall of the mobile phone?

If you use a vivo phone, the phone has no firewall, and the vivo phone I housekeeper is a built-in security management tool in the system, which can bring a safe device experience.

If you are worried about risky applications, you can go to I Manager-Security Detection-Detecting Related Malicious Applications, click the malicious application icon to enter the details page, and click the three points in the upper right corner to add the software to the white list.

For more questions, you can enter the online customer service of vivo official website-click on mine and enter "Manual" to contact the online customer service for handling.
