We recently discussed a bunch of features that the Tesla Android App is missing in comparison to the Tesla iOS App, but we didn’t look at the other side.
If you’ve got an NFC-capable Android phone and a Tesla, you actually have a feature that’s not available on iPhones. You can tap your phone on Tesla’s NFC card reader to unlock or lock your car, just like you can with your keycard. Tap to Unlock is enabled by default on Android and cannot be turned off on NFC-capable phones unless you disable NFC in your system settings.
Tap to Unlock
Android provides Tesla with access to the API necessary for Tap to Unlock to function over Near-Field Communications (NFC). This means that the Tesla app can serve as a backup keycard if, for some reason, your Phone-as-a-Key (PAAK) doesn’t immediately unlock the car upon waking it.
You’ll need to be a bit precise with this, as most phones have a small NFC location near the center on the back of the phone. You’ll also want to place it slightly under the B-pillar camera, where the car’s NFC reader is.
When you’re successful, the car will honk twice and unlock. Of note, this will not load your pre-set profiles as if you’re unlocking using your phone key, as the car treats this as a unique key. You will not be able to set up Tap to Unlock to load a particular profile – it seems to load a “default” profile every time. This also means that if you’ve got your mirrors set to unfold or your seats to move back, this will also not happen.
However, once you hop in, you can select your profile and everything will adjust to you. Your phone will continue to work as a phone key to keep you authenticated so that you can start your car.
Unlock Car Even If Phone Battery is Drained
This feature serves as a convenient way to get your car open and unlocked if your phone won’t power on or if the car doesn’t recognize your phone key, which can sometimes happen. On newer Android phones, NFC remains on even if your phone battery has run out since NFC uses so little power.
If you disable Bluetooth on your phone or your phone battery is on empty, your phone key won’t work, so you’ll need to authenticate again inside the vehicle to start the car. You can place your phone on either the Wireless Charger (for newer vehicles) or in the NFC slot between the cup holders and the center armrest to authenticate.
Other NFC Devices
For those more adventurous, you can also use other NFC-capable devices as Tesla keycards. Personally, the author uses an NFC-capable ring, as well as a third-party app on an Android Watch as backups. They serve solely as backups in the case of a lost phone rather than my primary keys.

Last night, Tesla released software update 2024.45.25.15, which includes FSD V12.6.1. This update adds support for all HW3 vehicles, including the Model 3 and Model Y. We’re excited to see the continued support for HW3 owners.
FSD V12.6.1
V12.6.1 is now going wide, according to Ashok Elluswamy, Tesla’s VP of AI. This update is going to the Model 3 and Model Y for the first time - as only the Model S and Model X were included in FSD V12.6.
V12.6 is a big step forward for HW3 - it includes End-to-End on Highway, Improved City Streets Behavior, and Smoother and More Accurate Tracking - all contributing towards a better, smoother, and more comfortable build of FSD. You can read our comparison between FSD V12.6 and V13.2.2 here.
In short, FSD V12.6 performs considerably closer to V13 than V12.5.4.2 - which is a massive improvement. It performs as well as the Cybertruck version of FSD V13, which is still missing a few features when compared to other HW4 vehicles, but it’s a great sign for HW3. A lot of the improvements can be pointed to in the improvements to lane selection and decision-making - the vehicle tends to hesitate far less on V12.6, meaning the ride is a lot smoother. Many early V12.6 testers mentioned that it felt more like V13-mini than anything else.
Legacy Model S & X
We haven’t seen this update hit any legacy Model S and Model X vehicles just yet. We’re not sure whether Ashok’s statement of “generally” applies here - but it should. If you do get the update, please let us know.
Legacy Model S and Model X vehicles are still on an older FSD build and potentially won’t see another FSD update for a little while longer. While they do have the same FSD hardware as other vehicles, there are enough hardware differences that require a build specifically for these vehicles.
FSD V12.6.1 is going out now to the redesigned Model S and X with HW3 and all Model 3 and Model Y vehicles with HW3. The initial wave went out last night, and we expect to see more later today or tomorrow. If this release ends up going “wide,” we should see much larger waves go out next week.
Tesla has issued a recall for some vehicles due to issues linked to a revision of the Hardware 4 (HW4) computer that was introduced this past November. This recall affects all vehicles with the revised hardware except for the Cybertruck, as it uses a slightly modified version of the HW4 system.
Many vehicle owners have reported a complete failure of their Autopilot computer, which not only leaves the vehicle without FSD and Autopilot but also disables many of the active safety features that make a Tesla what it is.
Let’s take a look at this recall - because the recall is partially physical and partially a software recall.
HW4 Failure
Tesla has identified the failure and flagged it to the U.S. NHTSA (but not Transport Canada or Euro NCAP at the time of publishing) as a recall.
Tesla mentions that the vehicle’s FSD computer circuit board may short circuit, resulting in the loss of the rearview camera image. The recall itself is focused on the rearview camera - as not having a functional rearview camera breaks a Federal Motor Vehicle Safety Standard. However, it does impact more than just the rearview camera.
As previously mentioned, users have experienced the full loss of Autopilot and FSD on these vehicles, as well as reduced traction control and removal of safety features such as automatic emergency braking, collision avoidance assist, and forward collision warnings.
While the vehicle remains driveable, it is not necessarily a good idea to drive the vehicle with many of these features, especially with the reduced traction control noted by many people. We’ve already noted that while Tesla has been sending tow trucks to pick up some vehicles, it is also prompting owners to drive the vehicle to their service center in some cases.
Remedy
Unlike most of Tesla’s recalls, this one isn’t entirely an OTA recall, owing to the fact that people have already experienced circuit board shorts and are already waiting for replacements.
The software portion of the recall has already been mostly completed for any vehicles with Tesla software update 2024.45.25.3 or greater. However, a significant portion of the tracked fleet remains on update 2024.44.25.2 (approximately 20%), so we recommend updating your HW4 vehicle whenever you receive the notification.
On the hardware side, Tesla is immediately identifying and replacing hardware that has had circuit board failure. Tesla is also reaching out to customers who have expressed intermittent issues with Autopilot features, active safety features, or vehicle cameras that don't display correctly. If you have experienced any of these issues in a late 2024 vehicle, we recommend submitting a service ticket with Tesla to ensure that your vehicle isn’t affected by this recall.
