Android Auto as a launcher: an Open Headunit experiment outside the car

⚡ The gist in 5 seconds - The point: Android Police journalist Rahul Naskar set up Android Auto on a spare phone and uses it as a minimalist launcher outside the car. - Availability: the Open Headunit app is free on GitHub, while on Google Play it costs $4. - Limitation: the screen stays constantly on in this mode and drains the battery quickly, so the author leaves the phone on the desk and doesn't take it along. ### 🔍 What was found In an Android Police piece dated September 26, 2026, the author, who has eight years of Android coverage under his belt, described how he turned a spare smartphone into an Android Auto display. First he installed Open Headunit from GitHub, enabled Developer mode for Android Auto, and launched Self Mode in the app. Then in Android Auto he selected Start Headunit server in the three-dot menu, reopened Open Headunit in Self Mode — and the interface came to life. According to the author, an old tablet would also work for the experiment. In launcher mode, Android Auto shows only a limited set of apps: navigation and music, but not YouTube, Netflix, Instagram, or WhatsApp. An incoming call doesn't expand into a call screen, and the battery, clock, and network indicators remain in the lower-left corner — tapping them reveals whether a message has arrived. There's a microphone for voice queries; the author talks to Gemini via "OK Google." ### 💡 Why it matters In the author's opinion, this interface is the best way to stay distraction-free: regular launchers, even minimalist ones like Niagara, don't deliver the same effect. The absence of social media and short videos immediately kills the temptation to open them, and the built-in Digital Wellbeing features "don't come close" to this level of quiet. At the same time, the phone remains useful: music, navigation, and talking to the assistant are still available, so you effectively disconnect from notifications without giving up the pleasures. ### 🧩 Context The author long ago ceded the spot in his car to Android Auto, even though his main phone is an iPhone 16e. After learning that Android Auto can run on cars without native support, he experimented with an old car using a spare Android smartphone. Now that smartphone works as a desktop minimalist display. The author warns against doing this on your main phone: extreme minimalism ends up costing you more than you gain. The main downside is the always-on screen, which drains the battery fast.
