Thanks, just saw this thread and my wife will be the driver of a new Y. She had requested the FOB as well but wears an Apple watch and sometimes leave without her iphone. Glad to learn the Apple watch will work just as good as the iphone when not around.I bought my wife a fob for our Y. This was in March 2020 before she used to drive a lot more, and more times getting in and out of the car. Yes, the fob worked 100% of the time even when it just sits passively in her purse.
Maybe an Apple watch with an app to open the frunk/trunk (basically all the functions of Tesla app) is better than buying the fob. I use Watch for Tesla app in my Apple Watch to do pretty much all of the above functions, plus Auto Frunk by Tesla Offer help solve another first world problem. lol .
Kidding aside, I probably would not buy a fob if i were to do it over. Phone and key card is good enough.
Few more points - I used to have Samsung Galaxy with similar issue with yours. The Near Field Comm function works for Androids amd Tesla. Just tap your authenticated Android phone to the driver pillar below the camera and it will lock/unlock your car. It also works as key by tapping it on the sensor by the cup holders.
Google Assistant’s EV Car add on app can also be used to remotely lock/unlock, and whatever else - easily in an Android phone.
