We recently discovered that Tesla is adding the ability for customers to remotely share their vehicle’s screen to help solve issues.

This app update reveals that Tesla is working on a similar feature for the Tesla app. The Tesla app states: “Would you like to share your Tesla app screen with a representative? They will see only the app to guide you.”

Other phrases found in the app related to screen share include: Resume Screen Share, Would you like to stop or resume screen sharing? , and Starting Screen Share.

This feature does not appear to be live in the app yet.

Powerwall Calibration

Undocumented

Tesla is adding an option to calibrate your Powerwall. The app states: “Powerwall calibration is required for ideal performance of your system. Tesla strongly recommends you allow calibration to continue. You can delay calibration if you require your Powerwall to resume normal operation for critical events like an upcoming planned grid outage.”

Users will be given the option to delay the calibration, but sometimes it appears that it will be required, with phrases found in this update that state: “You are unable to delay this calibration.”

The calibration process, which improves charge level accuracy and optimal battery performance, can take up to 72 hours, according to Tesla.

Undocumented

This app update adds support for Tesla’s new Standard models. It adjusts the visualizations to account for the changes in these models, such as the lack of a rear display, new front bumper, new wheels, and the new roof on the Model Y Standard.

It also reveals the codename for these models, the Model Y Standard was already known as E41 Bayberry, but we now know that the Model 3 Standard has a codename of D50 Poppyseed.

Tesla now offers a range of vehicles that either support or lack certain features. It’s not just about newer models supporting features, and legacy models not supporting them. With the introduction of the Standard models, Tesla now offers vehicles with and without glass roofs, as well as models with and without powered mirrors or seats with and without button adjustments.

With this update, Tesla has added variables for numerous features, which they use to build the dynamic vehicle model. For example, they have a variable optional_has_real_display to tell whether a rear screen should be rendered, optional_turn_indicator_control_type which lets the renderer know whether a stalk should be included and more.

They include variables for various features, such as unreal visualizations, whether a vehicle is in China, and whether it has a rear display, a front bumper camera and others.

Different Types of Front Bumper Cameras

Tesla Different Types of Front Bumper Cameras feature in update 4.49.6
Undocumented
Undocumented

Tesla has included some variables in this update that potentially hint at them using different front bumper cameras. This update includes phrases such as FRONTFASCIACAMERATYPEIMX963 and FRONTFASCIACAMERATYPENONE.

The IMX963 appears to signify the type of camera the vehicle is using, potentially indicating that Tesla plans to use others in the future or is leaving the possibility open. Tesla uses different parts from various manufacturers with functionality that’s the same or similar.

However, Tesla could also introduce new functionality with updated hardware. We’ll keep a close on this to see if Tesla introduces any additional front camera types.

Tesla App 4.49.5 Release Notes

Unreal Engine Autopilot Visualization

Tesla Unreal Engine Autopilot Visualization feature in update 4.49.5
Available Worldwide
Undocumented
Undocumented

There are now more signs that Tesla is moving to Unreal Engine visualizations for FSD and Autopilot. The new Model S and Model X are suspected to already be running visualizations using the new engine. While the new engine is expected to give Tesla more capabilities, Tesla appears to be using the same 3D models for now. The new Model S and Model X allow you to move the visualizations around in the Control menu, a feature not available in 2025 and older S and X models.

This app update mentions isUsingUnrealApViz, hinting that some vehicles are running Unreal Engine. Given the nature of the flag, this could also mean that not all vehicles will support Unreal Engine. It’s suspected to only be available on AMD Ryzen-based vehicles.

Improved Dashcam Streaming

Undocumented
Undocumented

Tesla’s Dashcam app feature is fantastic, allowing you to view Dashcam footage without having to remove the USB drive from your vehicle. However, the streaming quality is noticeably worse than what’s available in the vehicle.

This app update includes several phrases that hint at Tesla supporting dynamic bitrates in a future update, potentially allowing users to view video in higher quality when the vehicle has a strong connection or is connected to WiFi.

The phrases included are:

  • "clearSupportsFlexibleDashcamBitrate",

  • "getSupportsFlexibleDashcamBitrate",

  • "hasSupportsFlexibleDashcamBitrate",

  • "setShowDashcamViewerBitrate",

  • "setSupportsFlexibleDashcamBitrate",

  • "DASHCAM_VIEWER_DOWNLOAD_BITRATE_KEY",

  • "DASHCAM_VIEWER_STREAMING_BITRATE_KEY"

Tesla has updated the app’s maintenance section under Service > Request Service > Maintenance. The app now pulls data from the vehicle and shows the same recommended maintenance as shown inside the vehicle under Controls > Service > Maintenance.

While the app previously displayed regular vehicle maintenance and their estimated costs, now the app can tell which items are overdue and which ones have been performed recently. The Maintenance section in the vehicle allows owners to record regular vehicle maintenance such as replacements for wiper blades, cabin air filter, low-voltage battery, as well as other common tasks.

Vehicle Sharing

Tesla Vehicle Sharing feature in update 4.49.5
Undocumented
Undocumented

New code in this app update points to a potential new way to share vehicles in the future. Tesla added a lot of new strings regarding vehicle sharing and bootstrapping, including key values such as 'bootstrap_vehicle_access_add_to_mobile_app': 'Adding Vehicle to Mobile App',

'bootstrap_vehicle_access_connecting_vehicle': 'Connecting to vehicle...', 'bootstrap_vehicle_access_successful': 'Vehicle added successfully'.

Tesla already lets you share vehicles by adding a secondary “driver” account or by sharing the vehicle with another Tesla account. It’s not clear what improvements these changes can provide or how they’ll differ from what’s currently available.

Currently, secondary Driver accounts have some limitations in the Tesla app, as the app restricts features such as Charge Stats and Roadside Assistance to the primary account holder only.

  • 'Nearby Supercharger · >60 min wait to charge',

  • 'Waitlist to Charge · <5 min wait'

Robotaxi Updates

Undocumented
Undocumented

Tesla continues to integrate a lot of Robotaxi code into the main Tesla app. However, it’s not clear whether Tesla plans to add Robotaxi functionality into the main app itself, or if the two apps are just sharing a lot of the same code.

This update includes more Android-specific details, suggesting that Tesla may be close to releasing an Android version of the Robotaxi app.

Some of these phrases include:

  • android_native_alicorn_android_12_ble_permission_notification_content: To enable, allow Nearby Devices permission and restart the app,

  • android_native_alicorn_android_12_ble_permission_notification_title: Auto-unlock disabled,

  • android_native_alicorn_auto_unlock_enabled: Auto-unlock enabled,

  • android_native_alicorn_foreground_notification_title: Ride Access,

  • android_native_alicorn_status_bluetooth_disabled: Turn on Bluetooth to enable Auto-unlock,
