•  If you attach a screen protector or optional accessories to the touchscreen, the 

touchscreen may not function properly.

or if you tap the screen with sharp objects or your fingertips, the touch screen may 
malfunction.

•  The touch screen may malfunction in humid conditions or when exposed to water.
•  Restart your device to clear any temporary software bugs.
•  Ensure that your device software is upgraded to the latest version.

on the device to regain functionality. If your device is frozen and unresponsive, press and hold 
the Power button and the Volume button down simultaneously for more than 7 seconds to 
restart it.
If this does not solve the problem, perform a factory data reset. On the Apps screen, tap 
Settings

ERASE EVERYTHING. Before performing the factory data reset, remember to make backup 
copies of all important data stored in the device.
If the problem is still not resolved, contact a Samsung Service Centre.

may have connectivity problems due to issues with the service provider’s base station. 
Move to another area and try again.

•  When using the device while moving, wireless network services may be disabled due to 

issues with the service provider’s network.
