Hi community. First of all I want to thank all the Devs here for contributing all the good stuff what makes my FP3+ such a great device.
I hope I’m addressing my “issue” in the proper channel (I don’t really know if it’s a feature request or a bug):
I’m running my FP3+ with LineageOS 17.1 and OpenGapps Nano. When connection the FP3+ via Bluetooth with my car the car does not show the signal quality of the connected device. It also tells me, that there is no service available. Nevertheless I can make an receive calls through the car system what is really strange. I tried to switch to the different Bluetooth AVRCP versions to fix this behavior (1.4 - 1.6) with no success.
BUT: When adding a second SIM into Slot 2 everything looks as expected. My car shows the signal quality and the provider information of SIM in Slot 1 when connected via Bluetooth. I tried this in two other vehicles from colleagues and it is exactly the same behavior.
My conclusion is that the LineageOS 17.1 Bluetooth stack is sending the connection status of SIM 2 if only one SIM is inserted into the phone (SIM 1 slot) which gives a misleading information to car systems. Luckily telephony works. It would be great if this could be fixed.
