"Simple Audiobook Player" on Android is just wonderful. Requires one-time purchase for some features I believe, but I've been using it for years without a single thing to complain about.
It also handles chapters, playback speed is very adjustable, and a feature I like the most is that it takes you back to the beginning of the sentence if you pause/resume.
