For what it’s worth (not much?) I’ve had no issues with Android on midrange Samsung phone and tablet. Running Sunvox and Koala.
Bought a Tascam field recorder and plugged it in to see if it would act as an audio interface; it just worked out of the box. Stereo input to both Sunvox and Koala! So I’m happy with Android.
Even tried updating to the latest OS to see if I could break it… still works.
