Why does my trunk open as soon as I hit play on my music app?

Due to Bluetooth button mapping or misinterpreted remote commands, the Samsung Galaxy S10 may cause the car trunk to open when music is being played via Bluetooth. This might be caused by a bug in the car's Bluetooth system, a Bluetooth-enabled key fob or remote, malfunctioning or incompatible car Bluetooth software, or active phone automation apps. Check the car's Bluetooth settings, update the firmware of the infotainment system, try various music apps, disable phone automation, forget and re-pair the Bluetooth connection, and look for third-party apps to resolve this problem.
