My Note II is completely stock. I like having the capacitive buttons always on when the phone is on. I never had a problem before the 4.3 update, but now they randomly go off even tough I have the "always on" setting checked in system settings>my device>Display>Touch key light duration. They will stay on for a while and then go off. I go back into settings uncheck "always on" then check it again and they do come back on. I was wondering if anyone else was having this problem and if there is a fix for this?
