I was using an IPhone 8 since I got the car 1,5 years ago and let’s say 90% of the time was working fine with some occasional hiccups. I changed my phone about two months ago to IPhone 13 Mini and got some updates (currently running on 2022.12.3.2) and almost 90% of the time, the car will NOT unlock unless I take out the phone from my pocket. I always have the app running and the background activity is also active.
Occasionally I noticed that if I’m slow with pulling the door handler, the car will unlock eventually with a bit of delay so that the window is not lowering fast enough when I open the door.
Is hard to believe this is related to the phone but more so an update of the car software or the Tesla app. I got today Tesla app 4.9.2 on apple and they talk about minor fixes and improvements. I will revert here if that makes a noticeable difference in the next few days.
