2023.20.1

Offline mode

Configuration & data usage reduction

Version 2023.20.1 includes an updated offline mode that is configurable. You can disable sending Telemetry data to Tesla(important for FSD Beta users), and the firmware updates don't have to download using the Tesla Android Wi-Fi network.

The ability to check if your car runs the latest Tesla firmware is not affected.

Kudos to Green and Soma for making this possible!

Full-Screen mode

Usability improvements

An early fullscreen frontend is now available. You can access it using a new "Go Full-Screen" button in the Flutter App or by navigating to fullscreen.app.teslaandroid.com.

The Virtual Display still needs to fill the entire window, and there might be some minor UI issues in the Flutter App.

Networking

Routing improvements

You can access your Tesla Android by typing using app.teslaandroid.com instead of typing the IP address.

The DHCP server is no longer using a public IP range. Tesla Android switched to a Carrier-grade NAT range.

Android Platform

Boot time optimization

Version 2023.20.1 takes ~10s less to boot when compared to 2023.18. This was made possible by changing the Wi-Fi network initialisation code.

Wi-Fi

Performance improvements

Version 2023.20.1 add support for 5GHz Wi-Fi. The new future can be manually enabled in Settings and should improve the network speed significantly.

Users with their own routers can now disable to Tesla Android Wi-Fi network altogether.

Flutter App

Stability improvements

Version 2023.20.1 improves the Connectivity Check module. The app is also fully integrated with a self-hosted instance of Sentry(Performance monitoring & Error Tracking).

The data is anonymised and no fingerprints are captured. Crash logs contain the version of firmware and display resolution.
Full Changelog: 2023.18.2...2023.20.1

2023.18.2

Virtual display

Performance improvements

Variable refresh rate mechanism introduced in 2023.18.1 is disabled due to its negative impact on the input latency and animation smoothness.

Android Platform

Stability improvements

Android has been updated to Android 13 release 43 with the latest security patches.

Web server

Usability improvements

Cache settings are now less aggressive. You should not need to clear browser data after every Tesla Android update.

2023.18.1

Virtual display

Performance improvements

The virtual display is now hardware accelerated via the V4L2 API. As a result, this solution behaves consistently regardless of CPU usage (gaming, video playback).

The capture mechanism has also been replaced. The new solution sends data to the browser less frequently if nothing is happening on the display. As a result, overall resource usage of the front end is significantly reduced in typical use.

Internally the refresh rate of the headless operation mode in drm_hwcomposer is now capped at 30Hz. The SufraceFlinger is not able to provide more frames to the virtual display(buffer allocation related).

System animation duration is now reduced to improve performance.

Virtual display window scaling has been modified to slightly increase text size in system apps; it makes them more easily readable when driving.

Browser audio

Usability improvements

Version 2023.18.1 adds the ability to control the sound settings in the Flutter app. The feature can be disabled if you intend to use Bluetooth Audio or other peripherals.

Virtual touchscreen

Multitouch support

Multitouch support is now available in Tesla Android. The overall stability of the component has been increased.

Android Platform

Boot time optimization

Version 2023.18.1 takes ~2/3x less time to boot when compared to other Android 13 releases.

Android Platform

Support for OTA updates

Version 2023.18.1 adds support for OTA updates. A/B (Seamless) mechanism ensures a safe installation with a rollback to the previous build in case of failure. The process takes place in the background; you can use Tesla Android when the update is being installed.

Navigate to Settings -> System -> Updater to check update availability in the future.

Updates are not incremental. You can skip a few versions and update directly to the newest build.

Only online updates are available in this release; connect your Raspberry Pi to your home router with an Ethernet cable to avoid data charges. Each update weighs around 1 GB.

Single image install

Usability improvements

The bootloader has been updated to support the single-image install process better. In addition, the filesystem will now expand to take advantage of the entire SD Card on the first boot(similar to how Raspbian behaves).

Any SD Card over 16GB will work with Tesla Android, but 64GB is recommended.

The download size has been significantly reduced, and the manual installation procedure has been deprecated and removed from the website.

Bluetooth

Usability improvements

Version 2023.18.1 fixes problems with Bluetooth Low Energy. You can now use wireless game controllers, OBD interfaces, and more. Bluetooth Audio stability is also improved.

Android Platform

Stability improvements

Android has been updated to Android 13 release 41 with the latest security patches. The platform is now in sync with the latest GloDroidCommunity AOSP base. All the board-related changes have been sent upstream, and Tesla Android was migrated to a new build mechanism to make future Android platform updates faster.

Flutter App

Usability improvements

The has been reorganized to make room for new modules. Tapping the version ribbon takes you to the screen with multiple tabs. One of them is the new Settings module, where you can control the browser audio.

Video playback

Performance improvements

Version 2023.18.1 adds AV1 decoding via ffmpeg_codec2. The new component takes advantage of multiple cores and performs better.

Connectivity

Usability improvements

Version 2023.18.1 adds support for Huawei(Brovi) E3372-325. The device is available in the European market.

Compute Module 4

Hardware improvements

Version 2023.18.1 adds support for the Raspberry Pi Compute Module 4 and was tested with both EMMC(32GB) and SD Card-equipped variants. The external Wi-Fi antenna is selected by default.

PWM fan support

Hardware improvements

PWM is now enabled on GPIO 18. Supported coolers will only turn on if necessary. You can change the settings in config.txt on the boot partition of the SDCard.
