Why are all the ports on my phone closed?

All the ports on android or IOS phones are closed or filtered even if they are not sleep and have internet traffic, so what is the reason for that?

Thanks :slight_smile:

How are you scanning the ports of your Android or iOS?

The phone ip is 192.168.1.100
First try: nmap 192.168.1.100 -Pn -p- -T4
The result: all the ports are closed or filtered.
Second try: nmap 192.168.1.100 -Pn -sY -p- -T4
The results: all the ports are closed or filtered.

Your android is only connecting to the internet and doesn’t have any TCP/UDP service open that’s why you are seeing all ports filtered.
