houseoffreedom I'm unsure what you're trying to ask. If you're worried about a system app misbehaving, then it sounds like you don't really trust the OS.
I'm unsure how Wireshark plays a role in this. Even if someone were sniffing packets between your phone and whatever the data's destination is, it wouldn't yield much information since most communication over the internet nowadays is encrypted.
houseoffreedom I stumble over sone system apps in the last time and i think of disabling some of them because in do not need them.
Please don't do that. Disabling system apps or changing their permissions can lead to unexpected results. If you do, then there's not much that anyone in the community can do for you since you've done something that's unsupported.
