Does android have a firewall

The operating system Android does not offer a preinstalled Firewall, but uses some functions that together fulfill the tasks of a Firewall. This includes, for example, the counter that lists the data volume used for WLAN and mobile data. For suspicious Apps, Android also asks you to allow access to the data usage manually. Unwanted requests are blocked to protect you from malicious software.

Is this protection sufficient or is another Firewall useful? In general, it can be said that the Android functions offer good protection through regular security updates. If you still want to feel more secure, you can also install a Firewall.
