I was rather wondering about that. I will adjust the code so that it checks the provider that is being used, and if it is not ExternalStorageProvider then it can fall back to the slower implementation that is more generic.

After reconsidering, I think maybe we just leave a comment and assume it will work on most providers, in case some OEMs use different package names for ExternalStorageProvider.
