Thosw are only some examples (already saw them here on XDA).. But I want to learn more, so I know what am I really doing (tweaking) in my phone, and stuff...
XDA is a good place to start learning them (and learned, I had) but I think I don't see like a full-jam-packed thread with information like those. I wish to learn more, so I wish if you would recommend me useful sites and links about them... I don't mind if it's too many details, like a book, I'm just eager to learn my Android...
Thanks for noticing, and a big thanks if you would!
