I have a LG G4 (ATT) and had a less than 25% success rate in unlocking my Model 3. I downloaded "Bluetooth Auto Connect" from the Google Play Store and so far (couple days) have had a 100% success rate. It keeps the phone in discover mode whenever it doesn't have a bluetooth connection. It can also activate an application (like the Tesla App) when it discovers a bluetooth connection. Found a couple of issues, it connects and disconnects when you are in marginal range, and it seems to drain the battery significantly faster. There are lots of settings, and I am no expert, so I am hoping others can help in coming up with an ideal configuration. There are similar apps out there as well, would like to know if anyone has had experience with them
