App info shows Mobile Data Usage from before apps Install

jacksonppp

Today (18.01.26) I installed Fossify Voice Recorder.
App info shows Mobile data usage from October 2025 through January 2026...

It's the first time I've installed the app.
Download/installed via Obtainium to owner profile (disabled) pushed to secondary.
It has no network permissions.

Can anyone explain?

Uodate: deinstalled and pushed again to secondary. It shows the exact same mobile data usage amount.

jacksonppp The statistics are carried over from a previous app given the same ID since it was freed up by the previous app using it being uninstalled. The stats are also shared across apps sharing an ID which is a legacy feature for user installed apps but heavily used within the OS. It's an expected limitation of how Android gathers the statistics.
