Can the other person tell I turned on auto-translate?

No. Translations show only on your screen.

The automatic translation looks wrong.

Check it against the original. In Dotok, tapping the bubble switches between the original and the translation.

WhatsApp supports the language — turn on auto-translate under ⋮ → Translate in that chat.
It doesn’t — use Galaxy AI Chat translation (Samsung) or a translator that floats over the messenger.
Lots of short, vague messages — a translation that reads the earlier messages gets fewer wrong.

Pressing and holding every message gets old fast. Here are three ways to have them translated as they arrive.

Supported languages only, and Android has fewer than iPhone. Menu names vary a little between versions.

Turn on Settings → Galaxy AI → Chat Assist → Chat translation
In the chat, tap the Galaxy AI icon → Chat translation on the Samsung keyboard and pick their language

Only on Galaxy AI models.

Dotok, the app we make, translates new messages for as long as its panel is open.

As messages arrive, translations follow. Messages already in your language are skipped. (Example screen)

Each automatic translation counts as one use (20 free a day) · can be turned off per messenger, and tapping still translates · Android 8.0+
