The service is sometimes a bit cumbersome. The way I can not find or do not implement mirroring the screen. Hastily I had my Bluetooth receiver sorted, now I lack the ability to search directly with Allcast albums and play. If I create a playlist in the Walkman app my Xperias then I can then select in the Allcast app and play. An enhanced playback control is still lacking but then. Unfortunately videos stutter too often. In the Google Apps I can not find a receiver. Why ????? So the app is only for cast photos. Therefore Disappointment prevails at the moment. It remains the hope of improvement.
