All the F buttons r'nt working can you please help

I would first try doing a soft reset by pushing and holding both the power button and the home button at the same time, continue holding until the apple logo reappears, then wait to see if it boots up. If that doesn't work, try doing a restore by plugging into PC and clicking on restore in iTunes on your PC. If this doesn't resolve your problem, call 1-800-MYIPHONE to set up an appointment in an Apple store so a tech can repair your device. Hope this helps!

Try pressing the reset button that is provided on the player... Simply take a pointed metal pin and push it in the hole provided on the player (the hole is next to the record button / hold slider)

mcdevito75 here, Bring laptop to Staples, Best buy for testing, sounds like that key could be hanging up. maybe some sort of oil needed.

could be fluff on the microswitch under the button, or it could be just broken. You can open the mouse body and blow the fluff out, or just get a new mouse - they don't last forever.

Take the battery out.. And blow on the battery. Put the battery back in turn the phone on. mash buttons hard enough that they can feel it.

if its a sgh600 samsung hold down the middle button on metal circle between telephone on off buttons that should automatically connect you to int net

i can understand the question please say clearly

if the navigation and answering buttons are working then the problem with Touch Software. contact at service centre

I got it! Take out the batteries and then hold down the power button (or any button) for a minute or two.
