Resetting "always/just once" option in android 4.1.2

[AC Question]

Hi,
my name is vivek.
This is my first android mobile.
recently while sharing a MP3 track on watsapp, i accidently clicked on "ALWAYS".

now i cannot seem to share the tracks even via bluetooth. it directly jumps to watsapp.

how can i get the options back.

i wanted to go for "launch by default" option in the app management bt it shows "no deafults set".

thanks

Welcome to Android Central! What phone do you have? Go to Settings>Apps>All (or in Samsung devices, the App Manager), select WhatsApp, and tap Clear Defaults.

In the Settings>Apps screen, tap the Menu button, and look for the Reset All App Preferences option. Try that.
