Hey there
By "annoying pop up" are you referring to the warning about high volume causing damage to bearing?
If yes then I'm afraid you're stuck with it. Samsung put this there as a safety message to protect people's hearing, provide choice and ultimately remove the risk of legal action being taken after users use a device at high volume for long periods and damage their hearing.
I am not employed by Samsung nor do I receive any remuneration as a Samsung Members Star.
My device is an S25 Ultra.
