Google began retiring Google Assistant on mobile devices on September 4, 2026, replacing it with Gemini as the assistant experience on Android. Google told users by email that Assistant on phones is being discontinued and that the migration may take a few weeks to reach everyone — after that, users can no longer use or switch back to Google Assistant on their phone, tablet, or paired devices.

What the shutdown covers
Google’s September 4 retirement applies to Assistant on Android phones and tablets, and through them to Wear OS watches, compatible headphones, and vehicles using Android Auto projected from a phone. According to 9to5Google, the company had already signaled that Assistant would go away in 2026, and this email provided the September 4 date. Once the removal reaches a device, invoking the assistant with “Hey Google” or a long press of the power button launches Gemini instead.
Not everything moves at once. Ars Technica notes that cars with Google built-in keep Assistant beyond September 4, and that people on devices that do not meet Gemini’s minimum specifications — or in regions where Gemini is not yet supported — may keep the old assistant for longer. Google had originally planned to replace Assistant by the end of 2025 but delayed the transition into 2026 while Gemini matured.
What this means for people who rely on AI assistants
For many users, the practical risk is not the model name — it is the routines. Assistant was predictable for quick voice commands: timers, reminders, smart-home controls, and navigation. Gemini is more conversational but can behave differently on direct device commands, so it is worth testing your most-used routines before Assistant disappears from your phone. IT之家 (Chinese) reports that on September 4 Google officially started the mobile retirement, with eligible Android devices switching to Gemini in batches over the following weeks.
This kind of platform transition is a good reminder of a broader point: when a voice assistant’s product lifecycle ends, users must re-learn or rebuild workflows. A desktop AI agent is different because it is not tied to one consumer assistant’s roadmap — your local files, approvals, and history stay on your machine, and the client keeps working with whichever model you choose.
Preparing for the switch
- Before September 4 reaches your phone, test reminders, alarms, smart-home commands, and navigation in Gemini.
- Keep important setup notes (device names, room labels) that you may need to recreate.
- If you do most of your AI work on a computer, consider a desktop agent that keeps your routines and data local rather than inside a single voice-assistant ecosystem.
Assistant has served Android users for almost a decade, but the future is model-based assistants. If you want an AI agent that runs on your own PC with local files and approval control, try downloading MOOGH for Windows.
