Hi , I just tested with Sigil it's not what I needed after I try around with it , because I cannot predict what future other users will use .. I need a more general purpose solution , for example I can provide a proper IOS ebook as Apple products are all the same but as in android , I seems to get different results on 10 inch tablets , galaxy note phones , and tablet 7+ . I am so lost I dont know what to do
@Peter , I have used apps such as ibook , Aldiko and Ebook reader , all display with weird results
