OK Google Lumos Feature in 2026

In 2026, Google is transitioning its classic Google Assistant to the new AI-powered Gemini on Android and other platforms. Google confirmed this transition has been pushed into 2026 to ensure a smooth migration.

This migration means traditional voice features (like saying “Lumos”) will now run under Gemini’s AI framework instead of the legacy Assistant.
