Google has set September 4, 2026, as the start date for removing Google Assistant from Android phones, tablets, Wear OS watches, and Android Auto, replacing it permanently with Gemini. The rollout takes several weeks, and there is no way to switch back once it hits a device. The announcement came via emails sent to existing Assistant users, which was posted on Reddit by user u/KxgOEjg7GcQqQsK. The email states that Google Assistant is "being discontinued" and that Gemini is now "the assistant experience on Android." Once the change is applied, users will no longer be able to use Google Assistant or switch back on their phone, tablet, or paired devices. Gemini will also replace Google Assistant on Wear OS watches, headphones and earbuds compatible with Gemini, and vehicles running Android Auto projected from a user's mobile device. Cars with Google built-in will retain Google Assistant beyond September 4. Users whose devices do not meet Gemini's minimum requirements or who live in unsupported regions may continue using Google Assistant past the cutoff.
