Looking for an ebook reader for Android that:

• is FOSS
• supports three or more columns and can make the text small
• has simple tap to move forward no slide fade flip or scroll just the next page instantly. Not accidentally go back a page because it misreads a tap as if it were a slide
• is for text formats, i.e. something like epub, txt, markdown, rtf, mobi or similar as opposed to PDF
• black text on white background no mandatory parchment look
