Google has finally put a date on one of its biggest software transitions. The company will begin replacing Google Assistant with Gemini on eligible Android devices starting September 4, 2026. This marks the beginning of the end for the voice assistant that has powered Android smartphones for nearly a decade.
The information comes from an email Google sent to users, which was later shared publicly. While the rollout starts on September 4, Google says the migration will happen in phases over several weeks. This means Google Assistant will not disappear from every device on the same day.
Once the update reaches an eligible Android phone or tablet, Google Assistant will be replaced by Gemini. Users will not have the option to switch back to Assistant.
The change is more than a simple rebranding. Google wants Gemini to become the default AI experience across its ecosystem. Unlike Assistant, which mainly focused on voice commands and basic smart features, Gemini is designed to handle conversations, content generation, planning, coding, research, and more advanced AI tasks.
This transition shows Google’s belief that the future of digital assistants lies in generative AI rather than traditional voice assistants.
The first phase will affect eligible Android smartphones and tablets that support Gemini. Devices connected to these phones will also be impacted.
According to Google, the transition includes:
- Android phones and tablets that meet Gemini’s requirements
- Wear OS smartwatches
- Compatible wireless headphones
- Cars using Android Auto through a connected smartphone
However, not every Google-powered device is making the switch immediately.
Cars with Google built-in, where the operating system runs directly on the vehicle, will continue using Google Assistant for now. Similarly, Google TV devices, Nest smart speakers, and smart displays are not part of this rollout. Google says it will announce its Gemini migration plans later.
This means Google will temporarily operate both Assistant and Gemini across different products until the migration is complete.
Google Assistant is not disappearing entirely on September 4. Devices that do not meet Gemini’s minimum hardware or software requirements will continue running Assistant. The same applies to regions where Gemini is not yet officially available.
Google has not shared how long these exceptions will remain. Eventually, the company is expected to phase out Assistant completely, but there is currently no timeline for unsupported devices.
Users do not need to manually install Gemini or change any settings. Once the rollout reaches an eligible device, the migration will happen automatically. The familiar power button shortcut or voice command that previously launched Google Assistant will instead open Gemini.
The gradual rollout also allows Google to monitor performance and resolve issues before the update reaches millions of devices worldwide.
Google Assistant was introduced in 2016 and quickly became one of Android’s biggest software features. Over the years, it expanded to smartphones, smart speakers, TVs, cars, earbuds, and smart home devices.
But the rise of generative AI has changed user expectations. People now expect AI assistants to answer complex questions, summarize information, generate content, and hold natural conversations instead of simply executing commands.
Gemini has been built for this new era. By replacing Assistant with Gemini, Google is simplifying its AI strategy and focusing its development efforts on a single platform instead of maintaining two different assistants.
