Why wouldn’t it be?  Has something changed?

Because i Saw on couple of review that trueplay doesnt work with Android and because of that the sound wasnt that good.

And i Saw that mant customer have problems with Android app

The Era 100 will work just fine with an Android phone.

The Era 100 features a Quick Tuning option that uses the Era 100’s built-in microphones to perform Trueplay. Just make sure the microphone is switched to on.

The only other feature that you will be missing because of your Android phone is the ability to connect to the speaker using AirPlay. But you can use the Bluetooth feature instead.
