Troubleshooting

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 

key for 8-10 seconds. The device will reboot automatically.
If this does not solve the problem, perform a factory data 

reset. Open the application list and select Settings

you may lose your connection to the network. Move to 

another area and try again.

Ensure that you have accessed the right cellular network.
