    I don't know if it's coincidence, but I tried something a couple of times now if the car doesn't unlock.

    I tapped my phone where you're supposed to tap the card.
    It unlocked immediately.
    This is with a Samsung S8 with NFC.


    Try it out.
    I'd be interested in hearing others experience.

    The card is RFID as far as I know, so NFC would not do anything. I think what you saw was coincidence.

    What I have seen is the phone not unlock the car, and then once I take it out of my pocket and wake the phone up, then the car will unlock without doing anything else. It's as if the background Bluetooth task that is supposed to unlock the car is asleep, but taking the phone out of my pocket (which on the Samsung Galaxy S8/S8+ will wake up the display) also wakes up the Bluetooth background task, allowing the car to unlock.

    Yes, I need to wake up my Galaxy S8 for key to work... really annoying!!!! I want a regular prox key fob because the phone app doesn't work well, and frankly pretty embarrassing when trying to show off the car to people!

    Probably completely unrelated, but I have noticed that sometimes my S doesn't recognize my key fob while it's in my pocket. Based on correlation in placement, it seems like it only happens when my phone is in the same pocket. But, it could just be the signal is blocked by my metal leg (sarcasm).

    Anyway, maybe there's something similar with phone -- Model 3 contact when it's in the pocket vs. out.

    I have the same observation. I don't have good luck in my back pocket approaching the car. Sometimes it won't start if the phone is in my front pocket until I remove it....

    The Bluetooth phone and media audio profiles always connect fine, I have never seen any issues with any phone I have used. (HFP, and A2DP profiles). The issue is with BLE Key management, the "Phone Key" in the Tesla app should say "Connected", to be able to open the door. I have observed that doing one of the below two things will certainly fix the issue.

    1. Killing the Tesla App, and restarting the app
    2. Restart the phone

    You should now see "Connected" under "Phone Key".

    Also, switching between 2 users/phones as keys makes this problem worse. If I use the same phone to unlock, there are no issues. (Galaxy s8, or s7 edge)

    I have a Samsung Galaxy S8+, no other users of the car.

    I have had frequent situations where the car won't unock with me next to it. If you pull up the Tesla app, it plainly says "Connected" under the phone key, but the car still won't unlock.

    Cycling bluetooth / airplane mode / restarting Tesla app fixes it.

    What version of Android are you on?

    Try going into Settings > Battery and be sure that the Battery Saver is "OFF".

    Then go into APP&NOTIFICATIONS > Advanced > Special App Access > Battery Optimizations > Select Bluetooth > Don't Optimize > Done... Then select Tesla > Don't Optimize > Done.

    Back to the home screen and then reboot and see if that solves your problem.

    Found some possible help on reddit:

    setting>device maintenance>Battery>unmonitored apps

    Add the Tesla app to the unmonitored list. Hope this helps.

    I've experienced something similar in the car. If my phone is in my left pocket, which it usually is, sometimes the car won't detect it initially, but it will detect it when I pull it out of my pocket.

    I am on Android 8.0.0.

    I have none of the settings you're referring to, which is the same problem I always have when I look up stuff for Android on the Internet. Nothing that anyone says, posts screenshots of, or gives step-by-step instructions for can be done on my phone, because nothing I have matches anything they're citing.

    I have nothing called Battery Saver.

    I have no App & Notifications section in Settings. I found a Notifications -> Advanced, but there's nothing in there about Special App Access.

    Bluetooth has no setting called Battery Optimizations.


    I found Battery -> Unmonitored Apps, but the Tesla app is already in there.
