Classic Phantom White not working reliably after upgrade

[photometer]

Today I upgraded my White Premier Phantom (both App and the firmware). I can see that it is now called Phantom I Light Chrome.

If I reboot the Device, it will come and I can connect from my iphone using bluetooth. However if I stop playing and let it remain idle for few minutes, I cannot play again either with Bluetooth or Airplay. Only after restart of Phantom will it play again.

This is not good.

Is there a factory reset procedure ?
