Hello,

Phone is a Xiaomi 14 T Pro under hyper OS 2.0.14.0 version 2.0.14.0 VNNEUXM

Phone is connected wirelessly to a Carpuride W702 Android auto screen, data provided via e-sim card n°2.
When receiving a call on the physical Sim card n°1, Android auto disconnect with the following message:
"Androidauto transport error,
Start wireless projection fail,
Please check phone".

I can reproduce this behaviour each time, It happens on other Andorid auto devices as well, only wirelessly.
When using a Google Pixel 6 phone, with the sam setup (1 esim and 1 sim), no disconnection occurs.

I suspect that when a call arrive on the sim not used for data, it disconnects shortly the data and Wifi and the link with Android Auto is down.
The reconnection is not automatic, I have to either reset the Android Auto device or switch Off/On the BT connection on the phone...

Any help is appreciated to diagnose this default!
