Package intelligence
Observed signing, permission, version and size signals from contributing devices - descriptive of that sample, not a verdict. These come from the v2 Package Search sync, which not every device has contributed to yet, so for some packages this detail is partial or not present at all.
- Signed by the device maker's own signing key (Concept2, Inc.), so it is an OEM preinstall. It also signs the Android framework, so it is a platform-level key on its device(s). Inferred from the certificate appearing only on Concept2, Inc. devices (54 packages, 54 observations).
- Its largest observed manifest declares 21 permissions: 6 runtime (user-granted), 5 signature or system-level, 8 install-time and 2 vendor or uncatalogued.
- Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
Declared permissions (21)
Largest permission set observed for this package. Text is Android's own published description where one exists; platform permissions Android does not document show their granted protection level (in grey) instead; vendor or unknown constants show the name only.

Manage on devices
ADB commands for this package (the inverse of each is included so you can undo). Run from an authorised shell or wire the equivalent into your DPC. Verify on a test device first - this database doesn’t yet classify which packages are safe to change. --user 0 targets the current user; drop it (and use a privileged shell) to act device-wide.
