If you mean playing songs stored on your Android phone, you can’t.  Both Google and Apple removed that function due to security reasons.

So basically my sonus speaker that I purchased to play music from my phone is now just a big paper weight. 

Your Play:3 supports DLNA/UPnP playback so you could try an App that supports that playback option, such as BubbleUPnP or Hi-Fi Cast etc.

Thanks for the info.

Hi-Fi Cast works a treat. 

Me sonus speaker is worth more than just a paper weight.
