Password: When the device lock feature is enabled, you must enter the password you set for 
the device.

•  When you are in areas with weak signals or poor reception, you may lose reception. Move 

to another area and try again.

•  You cannot access some options without a subscription. Contact your service provider for 

more details.

If your device has a touch screen and the touch screen is not responding properly, try the 
following:

•  Remove any protective covers from the touch screen. Protective covers may prevent the 

device from recognising your inputs and are not recommended for touch screen devices.

•  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.

If your device freezes or hangs, you may need to close programs or reset the device to regain 
functionality. If your device is frozen and unresponsive, press and hold the Power button for 
8-10 seconds. The device reboots automatically.
If this does not solve the problem, perform a factory data reset. On the Applications 
screen, tap Settings 

→ Backup and reset → Factory data reset → Reset device → Erase 

everything.
