[Q] Is there any true Silent Mode enabling app for Lollipop? topic

As the title says.

I am tired of finding an app which will bring back the Silent mode in Lollipop, nothing works, including the one which was released earlier today claiming about bringing Silent mode back, SoundHUD, it does not work on my Note 3.

So I am asking this here, in case there is an app and I don't know it.

Again, I have a Galaxy Note 3, so if there's an app which works on a Nexus or those type of devices doesn't mean it will work on mine.
