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 (OPPO), so it is an OEM preinstall.
- Its largest observed manifest declares 37 permissions: 11 install-time and 26 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 (37)
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_NETWORK_STATE |
Allows the app to view information about network connections such as which networks exist and are connected. |
ACCESS_WIFI_STATE |
Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices. |
BLUETOOTH |
Allows the app to view the configuration of the Bluetooth on the phone, and to make and accept connections with paired devices. |
CHANGE_NETWORK_STATE |
Allows the app to change the state of network connectivity. |
FOREGROUND_SERVICE |
Allows the app to make use of foreground services. |
INTERNET |
Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet. |
MODIFY_AUDIO_SETTINGS |
Allows the app to modify global audio settings such as volume and which speaker is used for output. |
QUERY_ALL_PACKAGES |
Allows an app to see all installed packages. |
RECEIVE_BOOT_COMPLETED |
Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running. |
VIBRATE |
Allows the app to control the vibrator. |
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.
