Hi, few months ago after a regular update, I started facing problems with my galaxy note9 sound specially the calling speaker as the sound is either very low or with high distortion ... this actually comes and goes and some times it's commonly coming...
hi... if you mean Bluetooth headset or even wired one... I did and no problems at all...the distortion happens through the phone call internal headphone and speakers ... even the ringing and alarm sound got distortion sometimes
