Open ports on Android 13 4.14 is this normal? What are they for, nmap results

[SKT89]

I ran an nmap scan on my Samsung A22 running Android 13 4.14, these are the open ports that were returned, I've checked the services and port numbers and not found much information, can someone shed some light as to why they're open and what they're being used for please?


Nmap scan report for 192.168.1.155
Host is up (0.18s latency).
Not shown: 993 closed tcp ports (conn-refused)
PORT STATE SERVICE
1070/tcp filtered gmrupdateserv
2383/tcp filtered ms-olap4
3031/tcp filtered eppc
8042/tcp filtered fs-agent
8087/tcp filtered simplifymedia
9002/tcp filtered dynamid
33899/tcp filtered unknown

Thanks!

These are the filtered ports also:

PORT STATE SERVICE
1045/tcp filtered fpitp
1083/tcp filtered ansoft-lm-1
3766/tcp filtered sitewatch-s
7741/tcp filtered scriptview
9102/tcp filtered jetdirect
9111/tcp filtered DragonIDSConsole
9999/tcp filtered abyss
13783/tcp filtered netbackup

I'm researching the services and port numbers, if anyone knows what they're for though and if it's normal could you please advise? TIA

Unless you are a developer, why is this even an issue?

Ports are a fundamental networking aspect, block all your phone's ports and you're blocking it from any online access.
This sounds like you're needlessly looking for problems that are not really problems.

I don't think it's an issue, I asked for more information on these open/filtered ports and as to what they're being used for, I'm just curious, I hope that's not an issue?

I'm looking for information as to why there's open/filtered ports running on my Android, I'm looking for information on these running services not problems, just info.

Have a look at this Wikipedia page: List of TCP and UDP port numbers - Wikipedia

Thank you, some of the ports are on there but not many of them, I have cross referenced what's available there but not getting much information on these services/ports.

Do a search for port 1022 or port 3031 or whichever port you're curious about.
