Google is set to expand its Gemini AI assistant across the Android ecosystem in 2025, including smartwatches, headphones, tablets, and cars with Android Auto. CEO Sundar Pichai confirmed during the Q1 2025 earnings call that Gemini will replace Google Assistant on these devices. While a rollout timeline hasn't been announced, more details are expected at Google I/O 2025. Code hints from Wear OS and Android Auto updates suggest Gemini will offer natural, conversational responses and real-time interactions. It remains unclear whether Gemini’s features will run locally or require cloud connectivity via a connected Android device.
