The most I've ever had to do was double tap the screen to enlarge text, my eyes were never so great to begin with and age certainly isn't helping lol.
Don't need a special phone app, I've seen some forums offer them, I've tried them, none seem to offer anything worthwhile. If somebody could make a case for an Android app I'd listen, but I can't imagine anything except local caching that couldn't be implemented server-side and a basic web browser.
I post *almost* exclusively from my Android phone. I don’t get the request for an app. I have very little trouble and the trouble I do have is because I hate on-screen keyboards and I have fat thumbs.
FR works just fine for me on Android. I’ve also posted from my Kindle, my family members’ iphones & ipads, and the TV. No problems there either.
Chrome, Safari, Dolphin, Tor. All good.
