when I open the pdf file, the font size is always small, and if I use zoom button, it will zoom the font size, but it's only a little bit, and will miss some word in the beginning and end of sentence. change the preference in the reader setting is no effort.

But open the epub file is different story, it runs very well to the size I want and no missing any words.

Any recommendation?

All the best!
