How to close the firewall of Xiaomi mobile phone

First, the closing method of Xiaomi mobile phone firewall:

You can find this network firewall program in the settings of Xiaomi mobile phone. Tools opens the System Tools folder in System Tools, where you can see traffic monitoring. In addition to this Xiaomi's own firewall for traffic protection, Xiaomi also supports many firewalls that intercept spam messages and harassing calls.

Second, Xiaomi's firewall can save mobile phone traffic. The firewall can ban all programs that don't need networking (such as guitar solo, MX player, etc. ), which can effectively prevent background programs from stealing traffic (software is automatically updated) and solve problems such as advertisement push in notification bar. The mobile phone firewall has blacklist and whitelist modes, which can define the programs that allow Internet access, and can choose to control wifi or GPRS/EDGE/3G wireless networking. And the support log can be viewed at any time.
