I use both an iPhone 12 Pro and a Samsung S22. My experience is that the iPhone is way more reliable with a wired connection to my DS7 than the Samsung is.
The last few times I’ve used the Samsung it has disconnected after less than an hour. Both my phones and the car have the latest upgrades. I have also experienced overheating and shutdowns of the Samsung when it has run a few hours. I have used several USB wires. The iPhone usually works like a dream, even for 6-8 hours drives, straming Hi-Res music via 4/5g continuously.
Does anybody else have similar experiences? I like to use the Samsung too, as it has a diagnostic program for the car (via Bluetooth/OBD2), which shows up in Android Auto.
