Most Samsung (Tizen) error codes are the same problem wearing different numbers: the Smart Hub can't reach or authenticate to Samsung's servers. So the same two moves clear the majority of them — set a public DNS, and reset Smart Hub. Here's what each common code actually means so you're not guessing.
The Samsung (Smart Hub) codes
| Code | What it means | Quick fix |
|---|---|---|
| 0-1 (or 7-1) | Smart Hub couldn't fetch the Terms & Conditions on connect | Reset Smart Hub; confirm internet; re-accept terms |
| 001 | Region / country not set | Set the correct region; reset Smart Hub |
| 012 | An app install/update failed (looks app-side, but it's the network) — see apps that won't download | Restart TV + router; confirm stable Wi-Fi; retry |
| 102 | Can't reach Samsung's servers at all | Set DNS 8.8.8.8 / 8.8.4.4; update firmware |
| 105 | Smart Hub doesn't see a network connection | Set a static IP + DNS; reboot router; check MAC filtering |
| 107 | OpenAPI authentication — TV is online but can't authenticate | Set public DNS; reset Smart Hub; reboot router |
| 116 / 301 | Same OpenAPI/Smart Hub network family as 107 | Reset Smart Hub; reboot router; firmware update |
The 102-vs-107 distinction is the useful one: 102 means the TV can't reach Samsung's server (a DNS/route problem), while 107 means it reaches the server but can't authenticate (the Smart Hub/account layer). Both take the same fixes, but 107 points squarely at the auth handshake — see the full walkthrough for fixing Samsung error 107.
The two fixes that clear most of them
- Set a public DNS: Settings > General > Network > Network Status > IP Settings > DNS Setting > Enter Manually →
8.8.8.8. - Reset Smart Hub: Settings > Support > Self Diagnosis > Reset Smart Hub (default PIN
0000). This re-downloads apps and signs you out, so you'll re-add them after — but it clears the stale state behind most of these codes.
The Instant On gotcha
If a code (especially 107 or 012) survives a normal restart, Instant On is likely why. Samsung's fast-boot feature keeps the TV half-powered, so an "unplug and wait" power cycle never fully clears the network stack. Turn Instant On off (Settings → General/System Manager, location varies by year), then unplug for 30+ seconds. That's the fix people miss.
Codes that AREN'T Samsung's
Two common ones get blamed on the TV but belong to apps — don't factory-reset your TV for these:
- 3304 is a Paramount+ app error (connectivity / ad-blocker). Fix it in the app: clear its cache and data, reinstall it, disable any VPN or ad-blocker. There's a step-by-step for Samsung error 3304 if it persists.
- 9345 is a Prime Video error — a payment-method problem. Update your payment at primevideo.com and reinstall the app.
Rule of thumb: short codes and "X-Y" codes are Samsung/Smart Hub; four-digit codes tied to a named streaming app are that app's, not the TV's.
FAQ
What's the most common Samsung error? 107 — an OpenAPI authentication failure. Set a public DNS and reset Smart Hub.
Will resetting Smart Hub delete my settings? It removes installed apps and signs you out of Smart Hub, but it doesn't wipe picture/sound settings. You just re-add your apps.
Why do these codes keep coming back? Usually Instant On keeping the network stack from fully resetting, or an ISP DNS that struggles with Samsung's servers. Disable Instant On and set a public DNS.
Is error 3304 a Samsung problem? No — it's a Paramount+ app error. Fix it inside the app, not on the TV.
