How Do I Restart An App On My Samsung Smart TV?


Samsung TV Apps

You just sat down on your couch and have gotten pretty comfortable. You are ready to watch TV using your favorite streaming service, but come to find that the app you want to use isn’t loading correctly. I’ve had that problem and realize how frustrating it can be. 

Here are steps that are recommended by Samsung, and have worked for me when I have needed to restart an app. Whether you need to reset the Netflix app, or restart HBO Max, here is how you do it on a Samsung Smart TV.

Restarting or rebooting an app on a Samsung TV requires that the TV be rebooted. There are two ways to do this. With the TV turned on, hold down the power button on the remote until the TV turns off and back on, or you can unplug the TV and plug it back in after 30 seconds.

Doing one of those two steps will reboot the Samsung TV and force any and all apps to quit and be restarted once you open them again. This will usually fix when an app is frozen, but there are times where you may need to delete and reinstall an app, or you may need to reset Smart Hub. We will cover how to do those things in this article.

Perhaps your app is not loading or opening correctly, the screen is turning black, the app starts and then stops or freezes, or you are seeing some kind of error message displayed. The steps covered in this article will help resolve many of those issues for whatever reason your Samsung TV app is not working.

Cold Booting Your Samsung TV To Restart An App

It may be surprising to some people that when you hit the power button on the TV or the remote that the Samsung TV doesn’t actually turn off completely. Your Samsung TV goes into Stand-By mode when you hit the power button on your remote. 

Stand-by is a low power mode that keeps the operating system booted, but turns off the screen to save power. This enables the TV to turn on really quick, which is what most users prefer. This is similar to when you put a computer into sleep mode. It retains it’s memory and everything pops back up quickly once you power it back up. Notice how all the programs are still open? This is the same idea with your Samsung TV.

Rebooting your TV completely will clear the memory and close any apps that were open. Samsung calls this a “Cold Boot”. As I mentioned earlier, there are two ways to cold boot your Samsung TV.

Methods to reboot your Samsung Smart TV

  1. Turn on your Samsung TV. Once it is completely booted, hold down the power button on the remote. Your TV screen will turn off right after pushing down the power button, but continue to hold the power button until the TV turns back on.
  2. Unplug the TV from its power source. Wait 20-30 seconds to allow any stored energy to dissipate, and then plug the TV back into the power source. 

Either of these methods will completely reboot the TV, clear the memory, and cause all apps to be closed. 

Update Your Samsung Smart TV

THere are times when an app will require the TV to be running a certain operating system version. To make sure you have the latest version installed, follow these steps.

  1. Press the “Home” button on the remote control to open the Smart Hub
  2. Scroll to the left and open up “Settings” by selecting the gear icon (Should be the second icon from the far left side)
  3. Scroll down to and select “Support”
  4. Scroll right once and select “Software Update”
  5. Select “Update Now”

If you want your TV to automatically update in the future, go back to the Software Update menu and select “Auto Update”

How Do I Reinstall An App On My Samsung Smart TV?

There are times when an app becomes corrupted and you need to reinstall the app. This is a two-step process that requires first deleting the app, and then installing it again.

There is one thing I want to point your attention to before you try and delete an app. Preinstalled apps cannot be deleted without entering developer mode. That includes apps such as Apple TV, Netflix, and SmartThings. If you want to know how to delete a preinstalled app, watch this YouTube video. 

How To Delete an App On a Samsung Smart TV

How to Install an App on Samsung Smart TV

Now that the app has been completely uninstalled, you need to reinstall the app.This is done using the normal method you would follow to install any other app. Here is a video that demonstrates how to do that.

How To Reset Smart Hub On a Samsung TV

The last troubleshooting step I recommend to try if the other steps have failed is to reset the Samsung Smart Hub. Resetting Smart Hub will reset all your SMart Hub settings, accounts stored on your TV, and all of your apps.

  1. Press the “Home” button on the remote control to open the Smart Hub
  2. Scroll to the left and open up “Settings” by selecting the gear icon (Should be the second icon from the far left side)
  3. Scroll down to and select “Smart Hub”
  4. Scroll right once and select “Reset Smart Hub”
  5. Enter your PIN number for the TV. (The default is 0000)

Once the reset is complete, the TV will display a message and you will have to select “OK”

Additional Tips

In this article I’ve suggested the following troubleshooting recommendations:

  1. Cold Booting Your Samsung TV To Restart An App
  2. Update Your Samsung Smart TV
  3. Reinstalling An App On Your Samsung Smart TV
  4. Resetting Smart Hub On Your Samsung TV

Those will fix the majority of problems, but there are a few other things you can try if those don’t work.

  1. Reset the network connection on the Samsung TV
  2. Factory Reset your Smasung TV

Resetting the entire Smart TV is a bit extreme, and is rarely needed, but if nothing else has worked this is the last thing to try.
