Bluetooth calling issue on herolte

Hi everyone,

I’m getting BT call issues on mk. I only get weired sounds when connected to my car trying to call someone… the caller only gets weired sounds too.

I only switched to mk in December 17.

I did some research and it seems to happen on other aosp and los custom roms too for lately releases. Seems to be a Samsung thing.

However, I read about a workaround that if you set back to a older release e.g. from April 17, connect to the wanted BT devices and then dirty flash to the newest release, BT should work for the connected.

I would really like to try this with mk, but need copy of a April release.
I couldn’t find an archive or anything.

Could someone share a copy or point out where I could find one?

Cheers and best
