Galaxy S5 - Android 6.0.1 - Mute when locked?

[kotoxie]

Hi Guys,

I just upgraded to the latest Android for S5 > Version 6.0.1 (OTA Upgrade).

I'm using the fingerprint lock-screen on my phone.
before the upgrade I simply held the 'Volume-down' for a second, until it vibrated and went into silent.

Now, in the new Android version - it does nothing.

Can you help?

Thanks!O
