For an open source Android app for OpenStreetMap data, I like Organic Maps, and it normally works great with locally-cached maps. I've had better luck with it than with Google Maps or Apple Maps on phones.
(Though, I should mention that twice in the last year I've had Organic Maps become hopelessly confused about where I was, and where I should go. Both times, it had gotten a good GPS location, but then got confused while being out for an extended period of time, like maybe it was dead-reckoning only after that initial lock.)
Regarding Organic Maps: I would recommend keeping tabs on what is happening there since this year. They seem to be having significant governance issues.

Short story: forget Organic Maps, use successor CoMaps or competitor OsmAnd.

I was vaguely aware of this drama but hadn't looked into it. After reading through your link, I've switched over to Comaps. I don't like lack of transparency in community driven projects. Appreciate the flag!
+1 for organic maps. Have used it hiking and travelling all over the world. Never had any issues with it.
Not had any GPS problems other than that time I was in an area where it was being jammed. Bloody Russians.
