I’ve owned my Samsung smart tv for over a year and had no problems. However, recently when I’m streaming shows every 3-4 minutes my screen turns black and the video pauses. I checked and my wifi has no problems 400 mbps download 90 mbps upload is there anything else I can try to fix this?
Use VLC when watching movies add it to your app your using! It's easy to add it's in settings
Have you tried on another device? It might be the smart tv, is the app you use updated?
Is this not something to do with the TV memory? My LG does something similar when watching a football stream using the TV browser.
Did you try a VPN when streaming shows from your IPTV provider?
