Where is the voice button on the Samsung keyboard?

The voice button on the Samsung keyboard is the microphone icon on the toolbar above the letter keys. If the toolbar is collapsed, tap the arrow on its left edge to expand it; the mic often hides there.

If your voice to text disappeared on Samsung, open Settings, General management, Samsung Keyboard settings, and check Voice input is enabled and assigned to Samsung voice input or Google voice typing. Then confirm the keyboard's microphone permission under Apps.

When Samsung Keyboard voice typing still is not working, switching the voice engine to Google voice typing in the same settings screen fixes most recognition failures, since the two engines fail independently.

Or skip the engine roulette with a voice to text keyboard that carries its own.
