Good News concerning 5.1 Lollipop No its not released Yet :( but...

[systemofadown1]

Looks like after Samsung receives the 5.1 (which is slated to hit Nexus devices soon) update the Mute/Silent feature will be returned among other changes
It may take a bit but its still good news none the less for people like me that plan to keep the S5 for a bit longer.

This is concerning 5.1 not 5.0.1 just so there is no mix-up.

Several sources, google 5.1 lollipop & you'll more than likely find reviews of the release of 5.1 on Android One devices in the Philippines and Indonesia already.
Nexus devices are said to next in line as they are Google's babies. I have a nexus 9 and I'm currently waiting for the release in the USA. Once that happens Samsung should get a hold of it if they already do not have a copy.
Edit if I'm incorrect then I apologize but I believe its coming down the pipe
