It's nice to have a comprehensive guidebook written in clear English for an implement produced in a non-English speaking country where syntax, spelling and translation errors frequently appear in enclosed instructions which also often are frustratingly incomplete. Thank you for "taking charge" or our English speaking purchasers. There are some things I would wish to be included: First, an index at the end, because sometimes it is an uncertain use of a word that is the key to look up information. For example, what is the difference among "Save", "Store", "Export", and "Write to"? Not all of these are used in this User Manual but are common to electronic implements. Second, there are a few items unexplained such as "vCard file (VCF)" so the reader does not know what it is or to do with it. There are also other items that carry through with how to achieve entering and retrieving but leave uncertain their purpose. Third, there seem to be some things that perhaps are duplications of purpose for which a paragraph would help the user to understand and differentiate. An example is the uses for Hello Bixby and Ok Galaxy, and differences among Android files, Google files and Samsung files. Even with all these suggestions for improvement, however, I find the User Manual is still worthy of 5 stars.
