Google has finally set a hard date for one of the biggest transitions in its recent history: Google Assistant is being discontinued on Android devices starting September 4, 2026. If you’ve been using “Hey Google” to set timers, control your smart home, or get directions for the past decade, this is the moment it officially ends — and Gemini takes over for good.
Here’s exactly what’s changing, who’s affected, and what you should do before the switch reaches your device.
The Short Version
- Google Assistant will stop working on Android phones and tablets, Wear OS watches, compatible headphones/earbuds, and Android Auto (phone-projected) starting September 4, 2026.
- Gemini becomes the default “Hey Google” assistant on all these devices.
- Once the update reaches your device, there’s no switching back to Assistant.
- Cars with Google built-in Android Auto are not affected yet. Assistant keeps working there for now.
- The rollout will happen gradually and may take several weeks to reach every user after September 4.
Why This Is Happening
Google Assistant launched back in 2016 as a voice-based virtual assistant, handling everything from setting alarms to controlling smart home devices. Since 2023, Google has steadily folded its AI efforts into Gemini, and Assistant has been losing features and users to it ever since.
This isn’t a sudden decision. Google originally planned to complete this transition by the end of 2025, but pushed the timeline into 2026 as Gemini needed more time to mature and match Assistant’s core features. The September 4 date is Google finally locking in the finish line.
What Devices Are Affected
| Device Type | What Happens |
|---|---|
| Android phones & tablets | Assistant removed, Gemini becomes default |
| Wear OS watches | Assistant removed, Gemini takes over |
| Compatible headphones/earbuds | Assistant removed |
| Android Auto (via phone projection) | Assistant removed |
| Cars with Google built-in (Android Automotive) | Unaffected for now — Assistant continues |
| Fitbit devices (Sense, Versa series) | Assistant shutting down in the coming weeks, separately |
Google says the Google TV and Google Home speaker/display transitions to Gemini are coming separately, with no confirmed date yet.
What You’ll Lose (and What You Won’t)
Once the update reaches your device, you’ll no longer be able to open or switch back to Google Assistant — the option disappears entirely. Gemini takes over the “Hey Google” wake word, smart home controls, and general assistant tasks.
Google says it’s aiming for feature parity. However, some long-time Assistant users have reported that Gemini doesn’t yet fully match Assistant in certain areas, particularly some smart home routines and third-party integrations. If you rely heavily on custom routines, it’s worth testing Gemini now rather than being caught off guard later.
What You Should Do Before September 4
- Download and set up the Gemini app now if you haven’t already, so you can get familiar with it before the switch is forced.
- Check your smart home routines. Recreate any custom Assistant routines in Gemini to make sure they still work.
- Review app permissions as Gemini requires broader data access than Assistant did, so it’s worth understanding what you’re granting.
- Note your device type and plan accordingly. If you’re using Google built-in in your car, you’re not affected yet, but everything else on this list is.
The Bigger Picture
This shutdown lands in the same window as Apple’s own assistant overhaul. Apple’s new Siri, also powered by Gemini, is expected with iOS 27 this coming September. That means two of the biggest assistant experiences on the planet are being rebuilt around Gemini within weeks of each other, marking a real turning point in how “AI assistant” is defined going forward.
