After the November updates, my S9+ makes a beeping noise similiar to adjusting the volume controls. I have tried diiferent things from the internet and have not been able to fix. Sometimes it beeps when i press the power button to acess my lock screen, after I enter my password to unlock phone, and even when its not being touched with the screen off. When in Safe Mode it has not beeped so I can't say its hardware failure. Additionally, I have not added any new apps around the time this started happening.
The last two updates were Nov 9 and 15.
Thanks.
