The search term "samsung tool 191" is almost certainly a user typo for version 19.1. In software versioning, "191" would imply a major release (191st version), whereas "19.1" denotes a minor update to the 19th major version. Most archives from the 2015–2018 era reference versions like 19.1, 19.5, or 19.8.
