I'm not aware of anyone that does. What I can tell you is that as a user of both speech and braille, when I last looked at android a few months ago the experience hadn't improved much from back when I was a full-time android user 5 years ago which is sad. Brailleback, the accessibility service responsible for Braille, needs to be manually installed from Google play first. Once you get it going though there are still a number of frustrating issues like very nonstandard and counter intuitive commands, outdated or downright missing translation tables for a lot of languages (for example the one for my language is only available in 6-dot form even though Liblouis has had a computer braille version for years), sub-par translation for contracted braille if you use that, spotty connectivity, terrible typing experience (brailleback has its own software keyboard that you need to switch to before being able to type and doing this quickly is hard), and finally, you need Talkback to be also running for Brailleback to work, otherwise none of the navigation commands will work. And the problem with that is Talkback has no "mute speech" command so you're stuck either using your phone with braille as it talks away, or using it completely muted.

An alternative to this is installing a different braille service called BRLTTY, which needs to be sideloaded which adds additional complexity, and while that solves some of the problems I mentioned many still remain and a few new ones come up because BRLTTY is more confusing to a new user due to how it works.

So in short, if cost is a factor I'm pretty sure that buying a used iPhone, even something as old as an iPhone 6 which is now stuck on iOS 12 or an iPhone 6S which is on the latest version, would give someone a far better braille experience than any Android, maybe except the Amazon Kindle tablets which have their own screen reader where braille works a bit better from what I heard.

I'll add that Android did improve ...some ... in the last few years, some being the operative word and mostly because of a third-party screenreader called Jieshuo. However, yeah ...the braille experience is decidedly meh.

TLDR brailleback on android sucks.
