Just another hobbies.
It's start since I get my first Android smartphone around 2011, which is Sony Xperia Neo.
I feel the phone was not powerful enough, so I started following XDA Developer Forum for Android modding and rooting.
I also have interest on cracking, hacking and cheating on Android.

But now since Android smartphone become more powerful, I don't really think modification is necessary anymore except if you need root access.
