how to reactivate deativated features on my galaxy s4

[Rhuly Nhlangwana]

i recently upgraded to android kit kat and some of the features are deactivated like lock screen options

What do you mean deactivated? Which options are you asking about? Like slide to unlock or pattern unlock? If you only have options for PIN and password, did you encrypt your phone at some point? Encrypted phones don't allow you to use anything besides PIN and password.
