Important:
If
you don't know what it is or how to use it, and you dind't find this
because you needed it, don't download it. This is an app exclusively
used to an specific Samsung Galaxy S4 model and if you don't do it well
iy could break your phone. DON'T ASK ME HOW TO ROOT, just use google,
there are plenty of tutorials.
USE AT YOUR OWN RISK, before you use it make sure your phone and model are compatible. Don't blame me if you fuck up your phone, if you do, then you're just a noob and I'll ignore you ;)
