ZXReader v2.0.0 is a new e-book reader for Symbian s60 3rd or 5th edition mobile phones.

With ZXReader you can customize almost everything about the eBook display: from changing the fonts and colors to things like screen margins and the location of the info bar. And the best thing is that ZXReader is a freeware and signed as well!
Navigation is great: the app divides the screen into touchable regions that can activate different functions – by default, the top portion of the screen is used to move back a page, and the bottom portion to move forward. But you could also change it to left, center, right, and have each section perform a different task.

Features:
» Supported formats: TXT, FB2, ZIP, TCR;
» Support for many encodings;
» Automatic change of portrait / landscape mode when the phone turns;
» Fixing the desired orientation of the screen;
» Sensory management;
» Full Screen;
» Setting the font, including third-party ttf;
» Auto moving pages around;
» Office lighting – brightness is constant;
» Text – carry the words, bonding lines (cut into a line under a specific width before any editor)
» Splitting the screen into multiple active zones, each of which can hang some commands.

ZXReader is only compatible with two types of file formats: regular text files and .fb2 files. Text files are fine, but unfortunately don’t have support for things like bold headings for example.
