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 (Samsung), so it is an OEM preinstall, but 3 different certificates appear across the fleet, so OEMs ship their own builds of it.
- Its largest observed manifest declares 12 permissions: 7 runtime (user-granted), 3 signature or system-level, 1 install-time and 1 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 (12)
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.
| Permission | Description |
|---|---|
ACCESS_BACKGROUND_LOCATION |
This app can access location at any time, even while the app is not in use. |
ACCESS_COARSE_LOCATION |
This app can get your approximate location from location services while the app is in use. Location services for your device must be turned on for the app to get location. |
ACCESS_FINE_LOCATION |
This app can get your precise location from location services while the app is in use. Location services for your device must be turned on for the app to get location. This may increase battery usage. |
BROADCAST_SMS |
Signature-level system permission, for platform-signed apps. |
MODIFY_PHONE_STATE |
Signature or privileged system permission. |
READ_CELL_BROADCASTS |
Allows the app to read cell broadcast messages received by your device. Cell broadcast alerts are delivered in some locations to warn you of emergency situations. Malicious apps may interfere with the performance or operation of your device when an emergency cell broadcast is received. |
READ_PHONE_NUMBERS |
Allows the app to access the phone numbers of the device. |
READ_PHONE_STATE |
Allows the app to access the phone features of the device. This permission allows the app to determine the phone number and device IDs, whether a call is active, and the remote number connected by a call. |
READ_PRIVILEGED_PHONE_STATE |
Signature or privileged system permission. docs ↗ |
RECEIVE_SMS |
Allows the app to receive and process SMS messages. This means the app could monitor or delete messages sent to your device without showing them to you. |
WAKE_LOCK |
Allows the app to prevent the phone from going to sleep. |

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.
