After a truly long wait, it seems like Tesla is finally implementing Ultra-wideband (UWB) support for Android phones. Ultra-wideband allows for much more accurate phone tracking, leading to new features and a more reliable phone key. Tesla initially rolled out UWB Phone Key and app support for iOS users back with software update 2024.2.3 - which launched in February 2024.
Nearly a year later, we’re finally seeing signs of Tesla adding ultra-wideband support to Android devices. For Android users, this is exciting news, as it could add new features to your vehicle.
Android UWB Flag
A new flag related to ultra-wideband has been found in the latest Tesla app, version 4.41.0, thanks to a decompile by Tesla App iOS.
The new flag is labeled “MOBILE_APP_FEATURE_ANDROID_UWB_ENABLED,” which makes it pretty obvious that it’s related to Android UWB support.
Supported Devices
Most Android phones - especially flagship devices - already support and use UWB for other uses, but it’s not available on all phones. If you have a Google Pixel 6 or higher, Samsung Fold 2 or higher, Samsung S21+, or other recent Android phone, then your phone already supports ultra wideband.
However, since the advantage of UWB is the communication between the phone and the vehicle, your vehicle will need to support UWB as well.
Supported Models
Since ultra-wideband requires specific hardware, it can’t be added in a software update unless the hardware is already in the vehicle. Only some of the latest Tesla vehicles appear to support the new wireless protocol.
Here is the full list of supported Tesla models:
2024 Model 3 (Highland) and later
2021 Model S and later
2021 Model X and later
Cybertruck
2025 Model Y (Juniper) is expected to support UWB
The legacy Model S and Model X, as well as the first-gen Model 3 and current Model Y unfortunately do not support UWB.
More Reliable Phone Key
First up for UWB support is an improved phone key. The addition of UWB provides a low-power way for your vehicle to determine exactly where your device is in relation to your vehicle. That means the phone key will become more reliable - and more precise.
All supported vehicles above will support hands-free trunk opening, while automatic frunk opening is only supported on the Model S, Model X and Cybertruck.
For the first time, Android users will be able to set hands-free options for their vehicles, making it possible to open the trunk simply by standing behind the vehicle for two seconds. Once the vehicle detects you haven’t moved, a beep will sound and the trunk will open.
NFC Prompt
This app update is also adding a new interesting flag called SHOW_NFC_PROMPT. It seems Tesla is going to be adding a prompt to the app that will help people get back into their vehicles when their phone key fails. A device’s NFC capability actually remains active even if the phone has turned off due to a low battery. also remains active if you’ve drained the battery of your phone - so you’ll still be able to get into your vehicle and plop your phone on the charger.
Since Android devices can be set up and used as NFC key cards, you’ll be able to enter your vehicle even if your battery is depleted. This feature flag could be used to display something on your phone when the phone key fails to open the vehicle. It could ask you to use the device’s NFC capabilities or show you where to tap your phone or key card.
Release Date
Unfortunately, there’s no way of telling when this feature will arrive for Android users. However, seeing references in the app at least meaning that Tesla is at least actively developing the feature. While it could arrive any day now via a server-side change, it could also take another month or two for Tesla to complete any required testing across a variety of devices.

The reports of HW3’s death have been greatly exaggerated. With FSD V12.6.1 finally beginning to make its way to HW3 Model Ys, Tesla’s AI team is still hard at work improving FSD on Hardware 3 vehicles - and we’ve definitely seen a great step forward since V12.5 with the latest releases.
While Model 3 vehicles are still waiting for V12.6.1 to roll out to them, we’re already looking at the future of new features on HW3.
Reverse Confirmed
In a post on X, Elon Musk confirmed that reverse would be making its way to Hardware 3 vehicles soon. He jokingly pointed out that it probably stresses out the AI model quite a bit. The path planner currently thinks it can reverse, putting the vehicle in situations where it’s required to reverse, such as lining up for a three point turn. Right now FSD will draw squiggly lines all over the screen with its path planner.
FSD usually won’t give up until it really cannot move any further - it will inch as far forward as it can, and try planning the path to a three-point-turn. For now, FSD on HW3 vehicles isn’t allowed to shift in reverse outside of AutoPark, so it can’t continue and will stall out, waiting for a user intervention.
With FSD V13 for HW4, we saw vehicles gain the ability to Unpark, reverse and start FSD from park. It’s possible that when HW3 vehicles gain the ability to reverse, it may also include some of these other abilities, which truly start making FSD seem human-like.
Cybertruck’s FSD Too
As an aside, the Cybertruck’s build of FSD V13.2 is also not capable of reversing just yet. While the Cybertruck can AutoPark, it cannot Unpark, Park, or be Actually Smart Summoned quite yet - among other missing features.
Tesla’s official Cybertruck account also commented on Elon’s post - mentioning it's like an itch that can’t be scratched. Here’s hoping that Cybertruck also gets the chance to reverse soon as well.
All in all, it’s a big positive that Elon, as well as Tesla’s VP of AI - Ashok Elluswamy - have continued to acknowledge that changes and improvements for FSD on Hardware 3 vehicles are still coming. With this, and the knowledge that Tesla could potentially look at a hardware retrofit in the future if they can’t achieve Unsupervised FSD, we feel like it is far too early to say Hardware 3 is dead.
The question is - will the new Reverse feature push the build to V13? Or will we see FSD V12.7 next? Let us know what you think in the forums or on social media.
Tesla vehicles rely heavily on external cameras for their advanced driver-assistance systems (ADAS) and the future of fully autonomous robotaxis. However, driving in bad weather presents a significant challenge: keeping those cameras clean. Without a reliable cleaning solution, Robotaxis, which depend entirely on vision, cannot function safely and effectively.
Tesla owner Chuck Cook recently brought up this issue on X, saying to the Tesla AI team, “While I agree cleaning cameras while supervised is definitely something we need to consider... having an official post from @Tesla_AI about cleaning our own cameras is a bit concerning. You have a plan for this, right? Unsupervised can’t have customers wiping cameras.”
The Tesla_AI team responded, “On a more serious note, a more comprehensive cleaning solution is being worked on.”
Front Cameras
With the redesigned 2025 Model Y, Tesla introduced a front-facing camera, joining the Cybertruck in this regard. The Model S and Model X are also slated to receive this upgrade in the future and we eventually expect all Tesla vehicles to come with one standard.
Camera Washers
While the addition of a front camera is a step forward, it introduces another yet camera that needs to be cleaned.
Currently, the Cybertruck is the only known Tesla model equipped with a dedicated camera washer. This system drips water onto the front camera lens, allowing the wind to blow the moisture away. While it’s a simple and effective feature, it’s unclear whether Tesla implemented a similar feature in the new Model Y.
Rear Camera Shield

Tesla recently added a small shield around the rear camera to reduce the amount of dirt and water splashing onto the lens. Additionally, the rear camera on the new Model Y was relocated from above the license plate to the trunk lid. This repositioning presumably helps keep the lens cleaner by reducing its exposure to road spray.
While these adjustments are helpful, they don’t fully solve the issue, especially in harsher environments with constant rain, snow, or road debris.
Potential Solutions
There are several possible ways Tesla could address this issue:
Camera Washers: Expanding the Cybertruck’s washer feature to all external cameras or at least to the rear camera could provide a straightforward solution for keeping lenses clean.
Lens Coatings: Applying special coatings that repel water, dirt, and debris could reduce buildup on camera lenses. However, these coatings would still have limitations in extreme weather conditions.
Software Alerts: Software already notifies drivers when a camera is obstructed or dirty, but this wouldn’t solve the issue without a hardware solution to physically clean the lens.
Given that the new Model Y has already been announced, it doesn’t sound like Tesla incorporated a “comprehensive” solution to the dirty camera issue.
Tesla’s Solution?
Tesla’s mention of working on a “comprehensive cleaning solution” raises questions about what’s in development. The new Model Y doesn’t appear to feature anything we’d classify as comprehensive, and it’s unclear whether it even has a front camera washer like the Cybertruck.
One potential solution could tie into Tesla’s Robotaxi plans. Tesla is building hubs for its Robotaxis, where vehicles can be cleaned and maintained using robotic systems. These cleaning hubs could include robotic arms that wipe down exterior cameras when needed.
While this approach may work for Robotaxis in most situations, it doesn’t address the needs of private Tesla owners who rely on their vehicles daily. Tesla may assume that individual owners can manually clean their cameras as needed.
