Hello, I am new here. I recently got a samsung galaxy s3 GT-I9300 running on android 4.0.4 as a gift. It was bought in Shanghai but I am using it in Indonesia. The person who got it for me had it rooted upon purchase, but I actually do not want it to be rooted. So my question is that can it be unrooted? Also, if for some reason unrooting is not possible, will I still recieve a software update for jellybean 4.1.2 from the software update menu in the phone even if it is still rooted? because right now I still haven't recieved the update ( I check it everyday.) I also want to unroot it because the phone seems to be missing some features like S VOICE and allshare play. So please, any reply will be appreciated. Thanks a bunch!
