I'm not sure if this is the right forum to ask. If not, please move it to the right place.
I'm browsing the system software update for my phone (Kyocera Hydro Elite, 1.203VZ --> 2.006VZ), and found two files called mckiller.apk and mckiller.odex in /system/apps. I don't know what it does actually, but found a reference to "com.koushikdutta.superuser".
Is it what I think it is? Does it prevent to run Koushik's SuperUser on the phone?
