i rooted my phone.now how to uninstall unwanted apps ?
Link2Sd is a better one to uninstall unwanted apps.
But my suggestion is, use TITANIUM BACKUP pro, it requires ROOT. As you had rooted your phone, so you can easily use it.
It's a powerful tool, to simply uninstall in-built apps and unwanted apps, most importantly by using this app you can backup your entire phone's applications along with the data... you can restore them whenever you want.. JUST GIVE IT A TRY..
I'm also using the SAMSUNG GALAXY S DUOS GT S7562
