For users of Android 5 / 6:
Due to the design of Android 5.0 and above, users need to grant the permissions to Headuck Call blocker manually after installation, as follows-
For Android 5.0 or above: Under App Settings ＞ Filtering actions > Set Notification access, please grant notification access to the app for the normal function of "Pick and hang up" filtering method, and for stopping vibration during filtering.
For Android 6.0 or above: Under App Settings > Filtering actions > Draw over other apps, please grant permission to HeaDuck for the App to display pop-up window during call correctly.
Some manufacturers, such as HTC, placed additional checking on bluetooth and therefore pick up and hang up function would not work on non-rooted devices.
After installing the App, please start and enable blocking for proper functioning.
In some models, you need to manually grant this App auto-start and phone tapping permissions, before it can function normally.
If you use task killers (whether as part of the system or another App), this App should be exempted for its proper functioning.
To protect data of HKJunkCall, the App will not update through any proxy configured to inspect https traffic.
