This is the best educational app I've found so far, and now I don't need to carry a huge bag of books wherever I go. My only problem with the app is that whenever I try to select a paragraph and copy it, it somehow copies the whole chapter instead of that single paragraph.

It doesn't seem to work. It only shows a start screen. I have not gone further from that. I have Micromax Canvas A120 and its currently running on 4.4.2 KitKat. Please resolve this problem. Currently I have uninstalled this apk. If you fix then I would definitely install such good app.
