Android Auto is supposed to make driving easier, but that quickly falls apart if it's more annoying to use than your phone. This is especially true if you find yourself dealing with sluggish animations, delayed inputs, and an interface that takes ages to open apps. The good news is that Android Auto has a hidden developer menu with a setting that can make wireless performance feel much smoother. Your phone isn't the only thing struggling when Android Auto starts lagging The weakest link might not be your phone An incredibly common misconception regarding Android Auto is that its performance exclusively relies on your phone's raw processing power. People assume that the car screen is just a "dumb" display that the phone projects to, and when the interface stutters, they immediately blame the phone. And while the phone is absolutely the device that handles the brunt of the processing that goes into Android Auto, your car's head unit is still an active processing partner. Instead of simply mirroring your phone's screen, wireless Android Auto is essentially a compressed video and audio stream that your car has to decode and display in real time. The head unit has to decode the continuous video and audio stream, send the audio signal to the speakers, handle touch inputs, and simultaneously receive and send data over Wi-Fi. Unfortunately, many cars use cheap and often outdated processors to handle this connection, forcing the chip to work at its maximum and potentially overheat, causing it to struggle even more.

Weight 18g Connectivity Bluetooth, Wi-Fi Aside from processing power, smaller hardware limitations can also affect how smooth Android Auto feels. Even the digitizer's (the part that handles touch inputs) polling rate can affect the experience. When you tap a button on the screen or swipe, if the car's polling rate is only a few times per second, it can take hundreds of milliseconds just to register that your finger made contact. Hardware isn't the only problem, though. A lack of software updates can also be partially to blame. Google updates Android Auto fairly regularly, and some of those updates can introduce major feature improvements, redesigns, and other enhancements under the hood. If it's been a few years since you've bought your car and the manufacturer doesn't send out OTA updates, the software can become problematic. The infotainment system was built and optimized for an older version of Android Auto, and over time, the gap widens significantly between the modern Android Auto code and your car's legacy software and hardware. The easiest way to understand all of this is to think of Android Auto like video game streaming. If you've got a powerful gaming PC rendering a game flawlessly at a higher resolution and frame rate, but try to stream it over Wi-Fi to a 10-year-old laptop with a weak networking card and processor, the game is going to lag, drop frames, and feel unresponsive, even though it's technically running on your gaming PC instead of the laptop. A small quality trade-off for a smoother Android Auto Credit: Bertel King / How-To Geek Like with most other devices, one of the best ways to improve performance and responsiveness is to reduce the amount of work your phone and car's infotainment system have to do. The video stream is arguably the most demanding part of the entire Android Auto experience. By lowering the resolution, your phone has fewer pixels to render and encode, while your head unit has less data to decode and display. It also reduces the amount of data sent over the wireless connection, making the entire process easier on the hardware. The downside is reduced sharpness and image quality, but that's a small price to pay if it means Android Auto finally becomes smooth and usable again. To find this hidden option, open your phone's Settings, search for "Android Auto," and tap the result to open the Android Auto settings menu. Scroll down to Version, then tap it ten times until you see a prompt to enable developer settings on your phone. Tap OK to confirm. Next, tap the three-dot menu in the top-right corner and select Developer settings. Tap Video Resolution, then choose the resolution you want Android Auto to use. Depending on your car's Android Auto display, you might only have a 720p screen anyway, so a good starting point is Allow up to 1280x720 or 720x1280. Reconnect your phone to your car's head unit and test Android Auto. If it looks and feels the same as before, lower the resolution further to 800x480. Depending on your car's head unit, lowering the resolution can also affect scaling. It may make elements in Android Auto appear larger, although the exact result depends on how your head unit handles the lower-resolution stream. In any case, if the higher resolution was putting too much strain on either your phone or the car's system, the performance difference should be noticeable right away. A wireless adapter can often provide a better experience than cheap factory setups Your car's built-in wireless isn't always the winner Credit: Cory Gunther / How-To Geek One of the easiest ways to reduce the workload involved in running Android Auto smoothly is to switch to a wired connection. This eliminates the need to transmit data over the 5GHz wireless connection altogether, replacing it with a more stable and reliable wired data link. However, wired connections do reduce the convenience that Android Auto offers, which is hard to argue against. It's easy enough to plug in your phone if you're going on a 3-hour road trip, but for short drives around the city, wireless connectivity is hard to beat. Luckily, there is another way to reduce how much work your car's head unit has to do while maintaining the convenience of wireless: a wireless Android Auto adapter. These dongles plug into your car's USB port and make your wired Android Auto system communicate with your phone wirelessly. From the car's perspective, it's still using a normal wired Android Auto connection, while the adapter handles the wireless connection between the car and your phone. A wireless dongle won't magically make every car faster, but it can improve the experience in some older vehicles by reducing the workload and offering a more consistent connection. Sometimes the best fix is making Android Auto do less If you don't mind sacrificing a bit of sharpness, lowering Android Auto's streaming resolution is one of the easiest ways to make it feel smoother. A wireless Android Auto dongle can sometimes help performance too, especially if your head unit is to blame and not your phone. Before replacing your phone or blaming your car's hardware, try reducing the workload Android Auto has to handle.
