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 (NUU), so it is an OEM preinstall.
- Its largest observed manifest declares 8 permissions: 4 runtime (user-granted), 2 signature or system-level and 2 install-time.
- Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
Declared permissions (8)
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 |
|---|---|
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. Malicious apps may cost you money by making calls without your confirmation, or dial carrier codes which cause incoming calls to be automatically forwarded to another number. |
DISABLE_KEYGUARD |
Allows the app to disable the keylock and any associated password security. For example, the phone disables the keylock when receiving an incoming phone call, then re-enables the keylock when the call is finished. |
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. |
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_PRECISE_PHONE_STATE |
Signature or privileged system permission. |
READ_PRIVILEGED_PHONE_STATE |
Signature or privileged system permission. docs ↗ |
SET_WALLPAPER |
Allows the app to set the system wallpaper. |
WRITE_CONTACTS |
Allows the app to modify the data about your contacts stored on your phone. This permission allows apps to delete contact data. |
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.

Each record is a device profile (make + model + Android version). Each unique handset that syncs against a matching profile will increase the observations of a package, thereby increasing confidence that a package is expected to be on a device.
