I use the app on my 2 * Samsung Ace and Samsung Note as well as the 3 * PC app. I have just purchased a Tabtronics Quantum 7+ Jelly Bean Dual Core 8Gb tablet with 1Gb RAM, and SONOS app installs all correct, starts and then nothing just the nice blue Sonos Screen - nothing else. It is running Android 4.1.1 I did a factory reset, linked to my gmail account and then installed sonos still same problem.
