My mobile service is Cricket and I have a Samsung Galaxy S3 (SCH-R530C) phone. I would like to remove some of the apps that I do use, such as Google Music, Google Books. The reason is that I think they are contributing to my battery level going down too quickily. To do this, it is my understanding that I need to "root" the phone. Is it possible to find instructions for my specific model phone/mobile carrier? Thanks for any help.
