I've tried automatic reconstruction on multiple sets of pictures from my Samsung Galaxy s8. Each time I have not gotten any mesh created. My output file has the /dense and /sparse folders, and a database.db file, but nothing else. The folders are empty.
partial logs from reconstruction:

It is hard to say why it doesn’t work. If you show a few pictures of the scene, I might be able to help.
