I made some more tests, the phone calls inside the car via Bluetooth are completely muted (both loudspeaker and microphone). The phone rings inside the car, but when I answer the call, the voice and mic are completely muted. Still, I can commute voice between phone and car using the car’s application and use the phone, but it's dangerous to hold the phone when I drive. Before installing Malay patch everything worked perfect. Also, the music from my phone via Bluetooth sounds inside the car, but when I launch A2DP application the music becomes muted till I close the A2DP app again; the A2DP commands works normally, but no sound at all inside the car. Is it related to Viper settings? Also, A2DP worked nice before, with the stock Android 10. Can I solve these 2 problems or shall I revert back to stock Android 10 firmware? Thank you!
