Hi. Just installed new CC Google tv 4k and saw different problems. 1. I'm setting menu had no option for 4k. Also the Hdr and Dts not supported. 2. Can't activate "install from unknown sources" because the white highlighted stripe (that moves up-down to choose) don't exist, so i can't choose. 3. When I'm watching via iptv apk, after dinner minutes the screen turns into screensaver ( like when has no activity). 4. Also, many times, when going back from some apk, the screen remains black. Must push the back button to go to the menu. The device is first time used and it's connected to the tv via Sony sound bar that support 4k. The tv is hd 1080 from 2012-13 with hdmi and every kind of other connections. Thanks
