Google Gemini's Glow Overlay Is Redesigning Wear OS — But the Bigger Story Is the Assistant Shutdown on September 4

How the Glow Overlay Changes the User Experience

Previously, activating Gemini on Wear OS would open a full-screen app that completely hid the watch face and any running app . The new overlay fundamentally changes this behavior:

• Overlay, not interruption — Gemini now materializes as a floating layer above the active watch face or running app, so the watch face stays visible at all times .
• Non-blocking interaction — The lightweight overlay provides ambient visual feedback without seizing the entire display, making the assistant feel less disruptive on a small screen .
• New functional elements — The update adds live prompt transcripts, action confirmations, and a relocated microphone indicator, mirroring the phone experience .

Reports consistently note this is purely a visual and UX redesign — no functionality or assistant capabilities have changed .

Rollout Details: Versions and Devices

The Glow Overlay is rolling out through an update to the Google Gemini app on the Play Store. Key details include:

The Bigger Picture: Google Assistant Retires on September 4, 2026

This Wear OS update arrives as part of a much larger transition. Google has confirmed it will begin removing Google Assistant from Android and Wear OS devices on September 4, 2026, with Gemini becoming the sole AI assistant across phones, tablets, Wear OS watches, headphones, and Android Auto . Users were notified by email that "Google Assistant on your mobile device is being discontinued" . The change is final: once removed, users will not be able to switch back to Google Assistant.

Gemini's Growth by the Numbers

Gemini's user base has grown rapidly as it replaces Assistant. According to Alphabet's Q2 2026 earnings report on July 22, 2026, Gemini reached 950 million monthly active users, up from 750 million in February 2026 and roughly 350 million in April 2025 . The 900 million milestone was disclosed at Google I/O in May 2026 .

Mixed Early Reception and Known Issues

While the Glow Overlay has been positively received — Digital Trends called it "worth the wait" — Gemini's broader transition has faced a bumpy start. Multiple reports note mixed early reception, including reported bugs in smart home controls and functionality gaps compared to the legacy Google Assistant. Some users have experienced issues with routine commands and device integrations .

The Glow Overlay rollout modernizes Gemini's Wear OS presence just weeks before Assistant's official shutdown, giving the platform a consistent cross-device look at a critical moment when all Assistant holdouts must migrate to Gemini.
