Signing out of Netflix, and then signing back in, sometimes refreshes the problematic data enough to get rid of code UI-800-3. Since this is another easy fix, it should be one of the first things that you try.

Some streaming devices don't allow you to sign out of Netflix. These devices typically allow you to reset the Netflix settings, which essentially returns the app to the state it was in when you first downloaded it. This can effectively refresh the locally stored data, and you will have to sign back in afterward.

1. Navigate to Netflix.com/YourAccount.
2. In the settings section, click Sign out all devices.
3. Click Sign out.

After signing out of Netflix, and signing back in, you should check to see if you can stream anything. If you can't, then you will need to move on to more complicated fixes.

Some devices allow you to clear the Netflix cache, or delete local data, though a menu option. Others automatically clear this cache when you power cycle them. If your device has no option to clear the cache or delete local data, then shutting the device down, unplugging it, and then plugging it back in is all you can do.

To clear the Netflix app data on your Amazon Fire TV or Fire TV Stick:

1. Press the home button on your Fire TV remote.
2. Select Settings.
3. Select Applications.
4. Select Manage installed applications.
5. Select the Netflix app.
6. Select Clear data.
7. Select Clear data a second time.
8. Select Clear cache.
9. Unplug your Fire TV device for at least one minute.
10. Plug your Fire TV back in and check to see if Netflix works.

To clear the cache on a Roku:

1. Press the home button on your remote five times.
2. Press the up arrow button once.
3. Press the fast rewind button twice.
4. Press the fast forward button twice.
5. The Roku will restart.
   1. Note: You can't clear the data for an individual channel on a Roku.

Even when there is no way to reset or clear the Netflix cache on a specific device, there is a hidden reset procedure that works on most devices. This is not a normal menu option, and it requires you to enter a specific sequence of inputs on your remote control or game controller.

To reset the Netflix app on most devices:

1. Press up on the controller or remote control twice.
2. Press down twice.
3. Press left.
4. Press right.
5. Press left.
6. Press right.
7. Press up four times.
8. Select deactivate or reload.
9. Sign back into Netflix, and see if you can stream anything.

If clearing the cache or resetting the Netflix app doesn't work, then you will need to delete the app from your device. Once the app has been removed, you can reinstall it, sign back in, and check to see if you can stream.

Some devices come with the Netflix app, and you can't uninstall it. If you have one of these devices, then this isn't an option. Other devices refer to the Netflix app as something else, such as the Netflix channel on Roku.

Regardless of whether the Netflix app is called an app, channel, or something else, removing it and then reinstalling it will effectively clear and refresh the local data, which usually fixes error code UI-800-3.

If you have a Samsung TV, then fixing error code UI-800-3 may require you to reset your Smart Hub. This process is a little different depending on whether or not your remote has a number pad.
