I've found this very weird android application.
Seems to be some kind of calculator, but there is something strange with it. Can you find out what it is?

Flag is in Format: FLAG{...}
Note: You don't really need an android device to solve this. But it might be helpful :)
Just a tip : Use online apk decompiler to look at the source code
