I have used NextDNS to block Samsung ‘telemetry’, using two strategies, with mixed results:
-
Set up NextDNS on my router. This indeed blocked some traffic on the Samsung-TV. However, also some sites that I regularly use on my PC were inaccessible/blocked, and have spent a few hours trying to resolve this using whitelisting etc in the NextDNS settings without succes. Only disabling NextDNS resolved this issue, but doing so on a regular basis on a router is very inconvenient (adjust settings via webinterface and restart the router, which takes about 10 minutes…), so I decided to remove NextDNS fromn the router and configure it on my seperate devices.
-
Set up NextDNS on my Samsung TV. This also blocked the Samsung telemetry succesfully. However some Apps (YouTube plus local TV apps that I use to view previous episodes of TV-shows) were also blocked from connecting to the internet, making them useless. So I have removed NextDNS.
I don’t know if anyone has the same experience or has better ideas on how to configure NextDNS to avoid these issues, but I welcome suggestions!
