Chromium based android browsers currently don't have the support for "File System Access API" and Firefox mobile also doesn't have the support.

I have checked caniuse.com where it shows some browsers about the support for this API. But I don't know if there are any browsers that supports it and are not in caniuse.com

I would also be interested in any experimental version of browser that has this API. Thanks!

The File System Access API is currently not supported on Android. The feature bug to star is https://crbug.com/1011535. Starring a bug means you will be updated when progress is being made. Meanwhile, I recommend the browser-fs-access library as a solution that automatically falls back to an alternative implementation when the File System Access API isn’t supported.
