It’s obviously not your fault as that’s the state of Mastodon <=> Lemmy federation right now and this is how threads appear on our end:

And don’t worry you’re in the right community 😁 (assuming you didn’t indeed look for an official one managed by Google as that doesn’t exist)

As for your question, I don’t know about that process, but a quick Google search yields this source file: https://android.googlesource.com/platform/packages/services/Telephony/+/master/src/com/android/phone/vvm/RemoteVvmTaskManager.java

and when you scroll further down there’s this comment that explains its purpose:

Service to manage tasks issued to the {@link VisualVoicemailService}. This service will bind to the default dialer on a visual voicemail event if it implements the VisualVoicemailService. The service will hold all resource for the VisualVoicemailService until {@link VisualVoicemailService.VisualVoicemailTask#finish()} has been called on all issued tasks.

If the service is already running it will be reused for new events. The service will stop itself after all events are handled.

And here’s the doc entry for Visual Voicemail: https://source.android.com/docs/core/permissions/voicemail

tl;dr: It’s not suspicious, it’s part of the Android OS.
