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 (TCL), 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 25 permissions: 5 runtime (user-granted), 11 signature or system-level, 7 install-time and 2 vendor or uncatalogued.
- APK size ranges from 6.2 MB to 14.6 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 (25)
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.

FOREGROUND_SERVICE_SYSTEM_EXEMPTED |
Allows the app to make use of foreground services with the type "systemExempted" |

Signature or privileged system permission. docs ↗ |
READ_SMS |
This app can read all SMS (text) messages stored on your phone. |
