Buffering of Netflix on my smart TV is fine, whereas on a phone (Samsung Q60A) it is not

[sarahmartin]

Netflix can take a long time to buffer on my Samsung Q60A (Tizen OS) yet my ISP is rated at 120 Mbps. My MacBook and iPhone 14 are able to stream 4K on the same Wi-Fi without buffering. The Netflix app diagnostics show the TV shows have a network speed of 40 Mbps. I restarted the TV, unsubscribed/subscribed to Netflix, update software (TV is up to date), and restarted Archer router. Router QoS is off. TV has 5 GHz frequency and just 3 meters distance with the router. Is it the TV app possibly running on older TLS settings or is Samsung throttling applications? Any TV specific solutions (added DNS, resetting app cache etc) that might help?

It’s not likely that Samsung is throttling the app. The issue is usually with the Netflix app cache or network settings on the TV. Try these steps:

1. Clear cache of the Netflix app (Settings → Support → Device Care → Manage Storage).
2. Manually set DNS to 8.8.8.8 or 1.1.1.1.
3. Reinstall the Netflix app if possible.
4. Reset Smart Hub (Settings → Support → Device Care → Self Diagnosis).

This often fixes buffering issues that only happen on smart TVs.
