A rooted phone can be a lot more customized than just non rooted, use Titanium Backup for example to get rid off all the bloatware they put on the device.
Flash custom roms (MAKE SURE YOU ARE USING THE RIGHT ROM!! A lot of Noobs will flash a Rom meant for the International Galaxy S3 and than you end up with a paperweight) I've been rooting since G1 and every android phone after that I just rooted because carriers will put so much crap on it plus I am running a good version of JellyBean (Notice I said good not perfect)

Other things? You can overclock or underclock your CPU but know that all things are at your own risk since rooting just took away your warranty.. Plus the Galaxy S3 has a flash counter so if you flash something it will add 1 everytime (Unless it's an official Samsung Rom) this can be reset by using Triangle Away from the Google Play store..

cheers dude have some rep

I came across an app that lets you have free in app purches so say you can get a coin booster in the game for x,xx$ the app generates a card or something then tricks the play store into thinking u payed for it

I'd love to get the name of this app? And for OP I would recommend you install Lucky Patcher, in most cases you can modify apps to get rid of ads. And for the ones where it doesn't work there is always adfree.

Also obviously custom roms, themes, what have you. Custom boot/down animations as well as custom splash screens. I love how much you can customize rooted phones.

i might be rooting my phone but i dont know if its worth it
