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 profile
- Signed by the device maker's own signing key (Motorola), so it is an OEM preinstall.
- Its largest observed manifest declares 48 permissions: 19 runtime (user-granted), 1 signature or system-level, 18 install-time and 10 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 (48)
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.

|---|---|
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. |

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.

GET_PACKAGE_SIZE |

READ_CONTACTS |
Allows the app to read data about your contacts stored on your phone. Apps will also have access to the accounts on your phone that have created contacts. This may include accounts created by apps you have installed. This permission allows apps to save your contact data, and malicious apps may share contact data without your knowledge. |
