SMS Pattern Lock 1.1 requires the following permissions:

Allows applications to access information about networks.

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

Required to be able to access the camera device.

Allows applications to disable the keyguard if it is not secure.

Allows applications to open network sockets.

Allows an application to read from external storage.

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 receive SMS messages.

Allows an application to send SMS messages.

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.

Allows an application to write to external storage.
