How to set or change default apps in Android? Go to Settings – Applications – Manage Applications. Scroll through the list of applications and select the app you wish to deselect as the default.
In the Application Info section that opens, scroll down and tap the “Clear Defaults” button. Now, next time you use another app, or perform an action that requires an app to open where no default is set, Android will ask if you wish to use the app as the default.
Just enable the option “Use by default for this action”. That’s it!
