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 (OUKITEL), so it is an OEM preinstall, but 2 different certificates appear across the fleet, so OEMs ship their own builds of it.
- Its largest observed manifest declares 43 permissions: 10 runtime (user-granted), 15 signature or system-level, 12 install-time and 6 vendor or uncatalogued.
- APK size ranges from 3.8 MB to 9.1 MB across the reporting device profiles, so the build differs substantially between them.
- Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
Declared permissions (43)
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.

CALL_PHONE |
Allows the app to call phone numbers without your intervention. This may result in unexpected charges or calls. Note that this doesn't allow the app to call emergency numbers.
