Can't mute my phone anymore after One ui 8 update

[Siqili8983]

This morning my Samsung Galaxy s25 automatically updated to UI 8.0, right now seems like my side button cannot mute my phone only can turn on the volume or vibration

Anybody has the same issue and why it's like this?

Used to be able to put my phone into silent mode by holding the volume down button. Standard behavior for years and years. Then Samsung killed it for no reason at all. Has anyone heard of a fix for this yet?

I understand change can be frustrating. This particular change was likely made to prevent accidental silencing of the phone, resulting in missed calls/notifications.

Here's a workaround:
Settings > Modes and Routines > Routines. Tap the + in the top right.

If: button action > volume down > press and hold

Then: Sound Mode > Silent

Save the routine. Your phone now silences when you long press volume down.

Note: This method requires Routines+ to be installed.

To expound on @CEParsons fix, I have also set the opposite to turn sound back on for the long press of volume up.

Caveat, not silent, it's mute should this confuse you.
