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.

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.

PermissionDescription
ACCESS_NETWORK_STATE Allows the app to view information about network connections such as which networks exist and are connected.
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.
MANAGE_EXTERNAL_STORAGE Signature-level system permission, for platform-signed apps. docs ↗
VIBRATE Allows the app to control the vibrator.
WAKE_LOCK Allows the app to prevent the phone from going to sleep.

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.

Disable for the current user
adb shell pm disable-user --user 0 com.tct.exbook
Remove for the current user - a per-user uninstall; the APK stays on /system, so Restore re-adds it (-k keeps app data)
adb shell pm uninstall -k --user 0 com.tct.exbook
Re-enable
adb shell pm enable com.tct.exbook
Restore (re-install for the current user)
adb shell pm install-existing com.tct.exbook

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.
