"Headuck Call Blocker" is a call blocking application designed to safeguard users in Hong Kong against spam calls and unwanted phone solicitations. It leverages the HKJunkCall database along with additional criteria such as blocking invalid IDD, unidentified or non-contact numbers, and personalized lists. Moreover, the app identifies callers from public institutions or select commercial organizations through caller ID.

For Android 5 and above users:
Due to the design of Android 5.0 and higher versions, manual permission needs to be granted to Headuck Call blocker post-installation for optimal functionality.

To grant permissions:

• For Android 5.0+: Navigate to App Settings > Filtering actions > Set Notification access and grant access to enable the "Pick and hang up" filter method and stop vibration during filtering
• For Android 6.0+: Access App Settings > Filtering actions > Draw over other apps to permit HeaDuck in displaying pop-up windows correctly during calls

IMPORTANT:
In some device models, manual granting of auto-start and phone tapping permissions may be required for proper functionality. Avoid optimizing the app using task killers to prevent disruption in performance.

Following installation, ensure the app is started and blocking is enabled for seamless operation.
