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?

Have you followed these guidelines after an update?

@Siqili8983 It sounds like you are clicking one of the volume buttons, not the side button.

No I just use as usual when I was tr6ti turn off my phone, only can get to vibration

The only way I know that make the side button mute the volume is by using RegiStar. After the update did you make sure that Good Lock and RegiStar are fully updated? You may want to check that the side key mute is still enabled in RegiStar.

They are so stupid 

Why get ride of this function I really don't get it

Did @LongHiker's suggestion work using RegiStar?

If you want to use the volume button to mute, rather than vibrate, make sure you download Good Lock's routines+ module, then go to modes and routines and create a routine using button actions:
If:
Button action (vol down - press and hold)
Then:
Sound mode and volume -mute.
Save and exit.
The routine will run automatically and the press and hold action will mute your phone.

I have not tried yet, I will just do from the top for now.
