I remember reading a thread about the car not detecting the phone when walking up. I picked up my car 2 days now and had 0 issue with it. It works every single time and I thought maybe there is a small chance that some of you might not doing this correctly and that's why it's not unlocking the car for you. Here is what I have learned: 1. If I walk up to my car and my phone is locked, the car won't let me open the door. This is a good security feature (e.g., If someone steals my phone, they can't drive my car away) 2. What I typically do is as I approach the car I will unlock my phone then the car will work every single time. I always have Bluetooth, internet and gps turned on (assuming the car need to know that you are nearby and not some fake/random Bluetooth signal). I haven't tried having just Bluetooth on will make a difference or not. I'm currently using a Samsung s8 with the latest 2018.26.1 update. I haven't tried this but I'm thinking that I can set my model 3 as a trusted device on my s8 so that it will unlock my phone automatically when I'm near the car. If this works, I will never need to unlock my phone before hand anymore. I will do some testings and report back later. So for those that have issue unlocking the car, were your phone lock or unlocked?
