Why is my Samsung television showing error 012?

Error 012 is shown on your Samsung television due to internet interference. It indicates that the device cannot connect to the Smart Hub server, preventing apps from running, installing, or updating. This problem can be caused by a poor WiFi connection, a broken app server, obsolete TV software, or Smart Hub errors.

Samsung TV error 012: Eleven ways to resolve it

1: Verify the status of the WiFi network

Error 012 on a Samsung television suggests internet interference.

Therefore, you should first check the status of your WiFi network.

Your WiFi signal strength?

Is your WiFi connection stable and quick enough to power your Samsung television?

By fast and stable, I mean an internet speed of at least 50 Mbps…

There are two great techniques to test the stability and speed of your WiFi:

  • By doing a test of internet speed.
  • By linking it to other devices.

To check your Samsung TV’s WiFi internet speed:

Connect your Samsung TV to your Wi-Fi router with an Ethernet cable for more precision.

  1. Press the Smart Hub button on the remote control for the television.
  2. Select “Web Browser” from the menu.
  3. Visit the website https://www.speedtest.net/.
  4. Select “Go”

If the report indicates that your WiFi is “quick”, continue to step 2.

If it says “slow,” contact your ISP for assistance with troubleshooting.

To test the speed of your WiFi network with other devices:

  1. Obtain any form of apparatus (e.g., smartphone, laptop, or PC).
  2. Connect it to the same WiFi network.
  3. Launch any application on the device.

If the app is functional, the problem lies with your Samsung TV.

If it doesn’t, your internet is unstable. And you should correct it to make your Samsung television function more efficiently.

2: Connect to a separate WiFi network

If you are unable to fix your WiFi network, try connecting to an alternative WiFi network.

Suppose you’re utilizing a WiFi router with two bands.

Connect to the other network band, either 2.4GHz or 5GHz. Ensure that your Samsung TV supports one of these two formats.

Earlier models of Samsung televisions do not support 5GHz band networks. Here are several examples:

  • Samsung TV EH5300.
  • Samsung TV UNC9000.
  • Samsung TV PN60E530.
  • Samsung TV UN55B7000.
  • Samsung TV UN55D6300.

Smartphones function as WiFi hotspots as well. Also, you may attempt to connect with it.

How do I change the network on my Samsung television?

To modify the WiFi network settings on a Samsung TV:

  1. Using the remote, navigate to settings.
  2. Select General > Network > Open Network Settings from the menu.
  3. Select the WiFi network currently in use.
  4. Select “Disconnect”
  5. On the same screen, choose your secondary WiFi network.
  6. Enter your WiFi network’s password.
  7. Press the “OK” or “Connect” button.

Still unable to update apps? Proceed to step three.

3: Unplug the television and WiFi router

Occasionally, technical malfunctions prevent your Samsung TV from connecting to your WiFi. Consequently resulting in connectivity troubles between your smart TV and WiFi router.

But don’t fret…

Electronic malfunctions are tiny faults. Which can be resolved easily simply restarting your devices.

And the easiest method to do so is by performing a soft reset.

A soft reset refreshes the system of your device by forcibly shutting it down.

Typically, a soft reset requires you to unplug the devices for only a few seconds.

However, for this particular Samsung TV issue, the devices must be unplugged for at least 10 minutes.

Here are the steps:

  1. Ensure that both the TV and the router are ON.
  2. Unplug the television and router from the electrical outlet.
  3. Unplug the devices for 10 minutes.
  4. Reconnect and power on the devices.

After that, simply wait for your Samsung TV to reconnect to WiFi automatically.

4: Check if the app is functioning “I’ve already soft reset my devices. However,

I am still unable to launch apps on my Samsung TV.”

Work the other applications on your Samsung TV?

If so, the application you are attempting to launch is likely flawed.

Keep in mind that each application has its own server. That is, they may also commit some faults.

Therefore, if you cannot access even one app on your Samsung TV…

Check to see if the application is truly functioning.

To accomplish this:

  1. Grab any available device.
  2. launch the same application on that smartphone.

If it works, the fault lies with your Samsung TV.

If it does not, check the app’s manufacturer’s website for maintenance notices or similar information.

5: Reinstall the application

Before attempting to troubleshoot your Samsung TV, reinstall the program.

  • Account information
  • Caches and cookies
  • Downloadable films
  • Former software files
  • Program and server files.

That may appear insignificant to a layperson. However, these items can occupy a storage memory. And eventually cause the application to stutter and freeze owing to bugs.

To remedy that, remove superfluous app data.

And the fastest approach to do so is to reinstall the application.

Note that reinstalling an application will remove any customized settings and other data. Be sure to back up your data by linking your device to your Samsung account.
