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.

device profiles
- Signed by the device maker's own signing key (Samsung), so it is an OEM preinstall, and that single certificate is consistent across all 11 device profiles.
- Its largest observed manifest declares 35 permissions: 1 runtime (user-granted), 10 signature or system-level, 10 install-time and 14 vendor or uncatalogued.
- APK size ranges from 4.5 MB to 7.9 MB across the reporting device profiles, so the build differs substantially between them.
- Reported as an updated system app on 5 of 11 profiles - a newer build is installed over the one in the system image there.
Declared permissions (35)
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.
