I have read the thread on no Android integration for Trueplay, but I would hope spending 1500 on a system there would be a better solution than "borrow an iOS device from a friend"!  Especially after3+ years!!!  First thought, if it is a microphone issue, then standardize your system with 1 mic to calibrate your system with.  Yamaha, Marantz, Denon, Pioneer etc ALL provide a setup mic with their systems.  Microphones among iOS devices also differ, they are different from year to year and model to model.  So that verbage doesn't add up or holdmuch water.   Second, before the android bashing begins, I bet the cost of my system if the table was turned and it only worked on android and not iOS devices, there would be a loud outcry of Apple users, especially if told to go "borrow" an android from a friend.  Not that this will change anything but I got to express my opinion.  I'm the proud owner of a top-of-the-line Sonos system that is"Meh" at best.
