I have a Samsung TV and I have downloaded and setup the Smart IPTV app. I have a channel list and have uploaded and confirmed it works. However after about 15 to 20 seconds of streaming play, the screen blanks for 3 to 10 seconds after which video and sound returns. This only happens on Smart IPTV app. Netflix, Youtube and other apps work flawlessly. I am a bit lost and not sure what to do next. should I remove and reinstall the app? is there a setting that commonly fixes this situation? Any help will be greatly appreciated. Thanks Logan....
