Appearances are deceiving!

First of all the good qualities. The TV has a beautiful design, good image and the sound is also useful, Ambilight is quite nice.
But if you want to use the so-great features, so you get to know the true TV. He turned around after 2 seconds to the next station, actually normal. However, such as Samsung quickly "pass-through" is not possible! Too quickly press of your remote control, it depends also on happy times! In addition, the device has a very slow menus. Timeshift is partly but a recording can not be started, though a hard disk is connected (USB 3.0 and 1T). Did they still managed that the TV has recognized it, the TV Guide does not recognize the program!?! After restarting the device, the hard drive is not detected again, a vicious circle! Even with the WiFi it's a struggle. In the Support Hotline stated that several issues would be solved with the new update. But even with the new update and reinstallation no improvement in sight. Our 4 years older than Samsung Smart TV, the much better. For 400 I expected more.
