How do I fix a Samsung smart TV app that will not download?

- Resetting Smart Hub can remove installed apps and require signing in again.
Follow these steps
Test the network quickly
Open a known working app or network status screen to confirm the TV has internet. Reconnect Wi-Fi if the connection is weak.
You should see: The TV shows a working connection or reveals a real network outage.
Reset Smart Hub
Go to Settings > Support > Device Care > Self Diagnosis > Reset Smart Hub. Enter the TV PIN; if you never changed it, try 0000.
You should see: Smart Hub resets and Apps reloads cleanly.
Sign in and retry the download
Open Apps, sign into your Samsung account if prompted, and download the app again.
You should see: The app installs without the previous error.
Check DNS or Samsung account next
If downloads still fail, re-enter DNS as automatic or try Samsung’s documented DNS troubleshooting, and confirm the Samsung account is not blocked or signed out.
You should see: App installs succeed after the network or account correction.

Extra tips
What to look for: Errors such as something went wrong or check Wi-Fi during download, and whether other internet apps still stream.
Before you change anything: Write down any custom TV PIN you set; the default is often 0000 if unchanged. Note that Smart Hub reset can remove installed apps and sign-in sessions. Confirm Wi-Fi is working with a browser or YouTube test. Use official Samsung settings only.
