1. Samsung F62 Android 14.1Overall pretty good, but the paid version has an issue that the free version does not: On two of my Android devices (OnePlus N10 5G and Samsung Galaxy Tab S6), the app does not appear in the Open with menu from Google Drive or File Explorer for .djvu files.

2. Please solve this matter or tell me how can I go back to the prev version.This is very good Reader app facility to auto crop, night mode, orientation and zoom lock, help you alot with reading.

3. Having behavior like native Android (just hold text, and "copy" menu appear) will save much of my time.My default reader.I often have to scan parts of books for reading because our vision problems.

4. Thanks for the effort of making this really versatile ebook reader :D It would be nice though, to have PDF and DJVU reader access EBookDroid's settings and book settings so that there would be no need to do transfers.

5. Setting is not saved for other files (is this the feature?), for example : crop pages, horizontal scroll, screen orientation.

6. It will be the best app if they make scrolling upnor down available while in the drawing mode.You have page offset! Thank-you, being able to use a book's index page references without needing to adjust has made me very happy.

7. *If I minimize or change orientation, an annoying band comes on the book.* The previous version was good.

8. On latest versions of android half of the screen turns black after going to landscape mode.

9. The problem I face recently is; When i switch to other app ,go to setting or take a call; when i come back text is not visible and screen covered with apps logo.

10. This logo dosent go away and I need to reload book to start reading it again.

11. Simple, efficient,highly recommended to everyone,and especially those who need our of the box capabilitiesI was using ebookdroid for a long period of time and I was very satisfied with it.
