•Password: When the device lock feature is enabled, you must enter the password you set for the device.
•PIN: When using the device for the first time or when the PIN requirement is enabled, you must enter the PIN supplied with the SIM or USIM card. You can disable this feature by using the SIM security menu.
•PUK: Your SIM or USIM card is blocked, usually as a result of entering your PIN incorrectly several times. You must enter the PUK supplied by your service provider.

The touch screen responds slowly or improperly
If your device has a touch screen and the touch screen is not responding properly, try the following:

•Ensure that your hands are clean and dry when tapping the touch screen.
•Restart your device to clear any temporary software bugs.
•Ensure that your device software is upgraded to the latest version.
•If the touch screen is scratched or damaged, take it to your local Samsung Service Centre.
