Am satisfied. Operate the device with a Samsung Galaxy S3. App installed, plugged in, done tuning - work. The app crashes sometimes, but only when Rumschalten. If the station is running again and the phone is not touched, boils. I have the impression that crashes could have something to do with the switch portrait / landscape, but have not yet pursued. Signal strength is very good. Operate the TV to the Galaxy also in conjunction with a portable Bluetooth speakers to listen to the TV sound in reasonable quality - works. After continuous testing over about 1.5 hours about 50% of Galaxy batteries were used up (the Bluetooth connection for the sound the whole time was active) - so always always take power adapter or external battery during prolonged use !
Supplement: Meanwhile, I have tried the receiver in Ireland and the UK. There, he was useless because scanning will always crashed, then no channels were stored. Then the app is only crashed. Back home, I have circumvented the problems by I deleted the AppManager application data the app. Then channel scan, although it got stuck, but saved all stations has. Now running again everything so far. Nevertheless, deduction of points for the crappy app.
