Hi,
I have a galaxy s21+ on the latest version of Android. I'm on Poweramp build 925. Recently i have noticed that right when I connect to bluetooth, the volume jumps up and down for about 5-10 seconds before becoming stable again. I can see on screen the volume jumping up and down, and I have tried holding the volume up button and also pressing the volume up button rapidly when it happens, but it still bounces around. I have also tried connecting to different bluetooth devices and it happens on all of them. Is there a way to fix this? I have the disable absolute volume setting enabled in developer options, and I can't think of anything else to try. It only lasts a few seconds, but it is very annoying and it just started happening recently.
