The Fastest Reader so Far, if only it could support Forced Reverse landscape but this app is still the best.
Kinda crappy interface Randomly rotates the screen (even when my Android 6 is configured no *not* rotate), when reading a file and closing, it says "save and exit?" which feels inconvenient because I didn't edit anything, so.. save what? And it first opens a PDF file and on 2nd attempt it doesn't ("can't read file" on the same file it opened before). I will try some more PDF viewers.
Can't get through file manager to main storage It looks empty. Kinda material looks better that before but still weird. All in all, there are so much work to do.
Top bar blocks screen when scrolling When scrolling, the top bar (full screen, title or status bar?) blocks the reading area for more than 1 second EVERY TIME! Can you disable it or move it to the bottom? It's very annoying when you want to read! Also, why do I have to tap once THEN scroll? Both of these harm my reading experience. ...... That's not an advisement bar! Have you read what my concerns are about? Okay, nvm, I have already uninstalled.
And the winner is ... AnDoc! I have an LG G3, no slouch of a phone. Gorgeous graphics, and big screen that seem to be a problem for Acrobat (sluggish performance and slow redraw). Tried 4 or 5 PDF viewers that had top ratings and claimed high-speed performance. Each had different issues, from frequent crashes to clunky responsiveness. AnDoc is fast and runs without failure. Job well done!
