Gemini Replacing Google Assistant

On eligible Android phones, Gemini can become the primary assistant for voice activation such as Hey Google and touch shortcuts previously used for Google Assistant. Availability and setup vary by device, account, language and rollout. Google’s Aug. 6, 2026 notice says the mobile Assistant transition began Sept. 3 and will roll out over several weeks. After a device transitions, affected users may lose the option to switch back. Google notes exceptions for unsupported devices and different behavior on non-mobile products; check its current eligibility guidance for a specific device. Google’s current help pages describe switching back to Assistant where the setting remains available. Paired mobile accessories may follow the phone’s assistant choice, while many speakers, displays, TVs and cars continue to use Assistant. Test the routines that matter—alarms, smart-home controls, music, reminders and navigation—after changing the default. Gemini offers conversational assistance and may connect with Google apps through extensions where available. Assistant and Gemini do not have identical capabilities. If a command fails, review the app’s settings, account permissions and device maker’s instructions rather than assuming the feature is supported. Changing the default does not automatically delete the other app or its activity history. Google describes separate controls for Gemini Apps Activity and Assistant data. Review each history and privacy setting independently. Availability can also depend on Android version, app version, region, language and account type, including work or school eligibility.
