On Android? Trueplay requires an iDevice.

So can I not calibrate the system at all from an Android Device? 

Thanks not very knowledgeable about all this.

No. Sonos have said there are simply too many different makes of microphone in Android devices -- even multiple variations within the same product line -- to be able to characterise them all. Apple is far more strict in this regard.

You could borrow an iPhone/iPod/iPad from a friend to do the Trueplay tuning. Once it’s done you can turn it on or off from Android.

Thank you very much. You have been a big help.
