is there going to be option to play music direct from android devices rather than have an external source?

It's not on the phone. It may have been streaming from an online service, or an NAS, but it wasn't on the phone. If that guy is anything like most salespersons at a big box store, he knows as much about the workings of Sonos as he knows about quantum physics or brain surgery. The *very* last person I would trust for information about electronics is a sales drone.

Hi, i even asked the salesperson if he was sure it was on the phone - he went and asked the Sonos in-store specialist who said it was on the phone - if it is not on the phone then none of them know what they are selling - mis-selling

It wasn't on the phone. I don't care if the guy claimed he asked John MacFarlane himself, it wasn't on the phone. You should go back and ask to see the music on the phone deleted and then attempt to play it. Quite frankly; this speculation that Sonos has this function working in its demos to fool people into thinking it works, or they have somehow "hidden" this function from the user's once they get it home, is smack dab in the middle of tin-foil hat territory. Not everything is a conspiracy people, especially in regard to First World problems with luxury items like music streamers.

Another Android user here requesting support.
Give it a rest Carl.

I am awaiting Android support from Sonos before purchasing. However, I have seen third party app 'Twonky Beam' used to stream audio to Sonos (and video to Samsung TV). On Youtube, there is a video under Twonky Mobile (replaced by Twonky Beam). Within Google Play, the screenshots for Twonky Beam show Sonos as device. Some users prefer BubbleUPnp to Twonky to do similar thing - both are free on Google Play. Probably, worth giving a go before returning Sonos, but agree this is a huge let down from Sonos given size of Android market.
Enough already.

Is there another possibility? The phone on display is plugged in. I had always assumed that this was to charge the phone but could it be connected to the devices and sending music this way?

Sonos devices have no USB ports for the phone to connect to, but if the USB share on the phone were mapped to a drive on a PC, and the PC was sharing the mapped drive to Sonos, that could work. However, that would still require a PC, and why would Sonos share from a phone when a PC was available?

True. So it would appear that the only option left is that the phone is acting as a controller. But what it's controlling is still unknown.

Can I just add my vote to this feature. Also if anyone knows how to get bubbleUpnp to steam to multiple sonos renderers at the same time (party mode?) please let me know

I too agree, please Sonos hurry up and add this ability for Android. I paid a lot of cash for my kit and now i've moved to Samsung Note it hardly seems fair that i cannot use streaming.. I'm looking to add more units around the house but will hold off if you only support iphones
