Signal Spy 1.6.7 requires the following permissions:

Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.

Allows applications to access information about networks.

Allows applications to access information about Wi-Fi networks.

Must be required by an AccessibilityService, to ensure that only the system can bind to it.

Must be required by a VpnService, to ensure that only the system can bind to it.

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

Allows applications to open network sockets.

Allows an application to collect component usage statistics

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 access to the vibrator.

Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.
