I've just got a new Samsung Galaxy Y from Unique Mobiles (http://www.uniquemobiles.com.au). The package was still intact when I picked it up and the "don't accept this if this sticker is broken" sticker was still good as new. Now I'm new to the Android operating system (coming from an iPhone) and when I got my phone it had superuser already on it. I had no idea what it was so I just left it alone. Until a friend from school asked if I had rooted it, I didn't have a clue to what he was saying. He said the only way I can get it is by rooting it. I haven't given my phone to anyone to do anything with it, I've been the only one to use it and I'm 100% sure I haven't rooted it.
Now my big question is How did it get there? What does it do? Has anyone else had the same thing happen to them?
I was also just wondering about some more information on superuser, rooting and ways that it could have gotten onto my phone.
