Dictionary for Samsung, a dictionary app made by SELVAS AI (formerly DIOTEK) for Samsung devices, listed on the Galaxy Store under this package name with SELVAS AI as the seller. Its English label on devices is "Dictionary", with localised equivalents in other locales. The Galaxy Store listing describes two uses: as a standalone app, and as a floating dictionary, where the user presses and holds a word, taps the "Dictionary" icon and sees the definition in a pop-up. The listing says this works in the default Internet browser, Notes, Messages, Contacts and similar, but not in all apps installed by the user. It supports 33 languages across 62 dictionary databases, downloaded from More > Manage dictionaries > Available dictionaries, and offers a "Search Web" function for further definitions online. It is a third-party preinstall rather than a Samsung-built app. In every observation with signer data it is signed by a key attributed to DIOTEK that does not also sign the Android framework, and it is recorded here only on Samsung phones and tablets, across Galaxy A, S, Z, Note and Tab models. It requests permissions including INTERNET, READ_PHONE_STATE, SYSTEM_ALERT_WINDOW, GET_TASKS and REQUEST_DELETE_PACKAGES; this site aggregates permissions across observations rather than per build, so which builds declare them cannot be established. The listing itself explains a phone permission as being used to confirm purchase authentication and a storage permission for dictionary databases and fonts. For Android Enterprise, EMM and kiosk use it has no enrolment or management role identified in the sources cited here; it is a consumer education feature. Nothing in the sources cited here suggests that disabling it affects more than the dictionary app and its floating lookup. On dedicated or kiosk devices that must not reach the web, note the listing's "Search Web" function and the database downloads, and consider disabling it; on knowledge-worker devices it can be left for users who want it. Version note: it is recorded here from API 28 to API 35, and this site's roll-up reports versions from 3.002.016 (oldest) to 3.003.012 (newest), while the Galaxy Store listing shows version 3.003.013. No change of role tied to a particular Android or One UI release could be sourced.
