I don’t know about that but I’ll do some searching. One thing I forgot to mention is that the Hisense phones don’t have Google Play. The Onyx one does. Not a big deal because you can load XCSoar directly and anything else you need directly also. I should highlight that these phones all have GPS (making it easy to get up and running compared to a Kobo) but none of the ones I mentioned have a barometric sensor.
