Does Orbot have a list of default built-in obfs4 bridges? Or do users fetch them dynamically? I looked in the source code and found default meek bridges but not default obfs4.
I'm asking because we recently added a few new high-capacity default obfs4 bridges. https://bugs.torproject.org/18071 (1 bridge) https://bugs.torproject.org/18091 (2 bridges)
