my s4 soft keys do not respond

Welcome to Android Central! Does that persist after a reboot? If so, then try wiping the cache partition: http://support.t-mobile.com/docs/DOC-5744. If it still happens, then try booting into Safe Mode (instructions at the bottom of that link), to see if a 3rd party app is responsible.

Has anyone fixed the soft keys problem? I got this problem after upgrading my S4 to lollipop 5.0.1
