CallHeads is an Android app developed by phoku.

CallHeads first became available on 26 Jul 2013. It is estimated that CallHeads has been downloaded between 50000 and 100000 times from the Play Store.

CallHeads 1.6 beta 2 requires the following permissions:

Allows applications to connect to paired bluetooth devices.

Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call.

Allows an application to call killBackgroundProcesses(String).

Allows an application to modify global audio settings.

Allows an application to read the user's contacts data.

Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.

Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.

Allows an application to change the Z-order of tasks.

Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.

Allows access to the vibrator.
