Sam Locker is an Android app developed by 대구대앱창작터.

Sam Locker first became available on 22 Apr 2012. It is estimated that Sam Locker has been downloaded between 500000 and 1000000 times from the Play Store.

Sam Locker 2.1 requires the following permissions:

Must be required by device administration receiver, to ensure that only the system can interact with it.

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

Allows an application to expand or collapse the status bar.

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 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.
