Reset the Netflix App from the Error Message

A user may face the UI 800 3 error on the Netflix app due to a temporary glitch in the app modules as the app fails to load the essential modules to the device’s memory. Here, resetting the Netflix app through the error message may solve the problem.

1. Launch the Netflix app and when the Netflix error message is shown, open More Details.

Perform a Cold Restart of the Networking Equipment

A temporary communication glitch between the device and Netflix servers may cause the UI error 800-3 as the app fails to access its servers. In this case, performing a cold restart of the networking equipment (router, extenders, etc.) may solve the problem.

1. Power off the router and unplug its power cable from the power source.

   

2. Now wait for 5 minutes and then power on the router after plugging back its power cable.
3. Then launch the Netflix app and check if it is working fine.
4. If not, power off the router, TV, and streaming device like a Roku device (if in use).
5. Then unplug the power cables of these devices from their power sources and wait for 5 minutes.
6. Now plug back the power cables to the devices and power on the router.
7. Once the router is properly powered on, power on the TV and streaming device.
8. Then launch Netflix and check if its UI 800-3 error is cleared.

Change the Screen Resolution of the Device

If there is a screen resolution mismatch between the streaming device (like Roku) and TV, then that may trigger the UI 800 3 error on Netflix as the app fails to output content at the required screen resolution. In this case, changing the screen resolution may clear the error. For illustration, we will discuss the process for a Shield TV.

1. Launch the Shield TV Settings and open Device Preferences.

   

2. Now select Display & Sound and open Resolution.

   

3. Then set the Screen Resolution to 1080P and launch Netflix to check if it is operating fine.

   

4. If not, check if disabling Surround Sound in the Display & Sound option of the Shield TV clears the error.

   

Change the DNS Settings of the Device

If the ISP’s DNS servers are not able to translate the web addresses of the Netflix servers promptly, then the Netflix app may fail to execute with the error UI-800-3 as the app cannot communicate with its servers. In this scenario, changing the DNS settings of the device may clear the Netflix error. For illustration, we will discuss the process of changing the DNS settings of a Samsung TV.

1. Launch the Samsung TV Settings and steer to General>> Network
   

   

2. Now open Network Status and click on IP Settings.

   

    
3. Then select DNS Settings and click on Enter Manually.

   Google DNS
   8.8.8.8
   
   Cloudflare DNS
   1.1.1.1

   

5. Then apply the changes and power off the Samsung TV.
6. Now wait for a minute and then power on the Samsung TV.
7. Then launch the Netflix app and check if it is operating fine without the UI error.

Set the HDMI Optimization of the Device to Best Framerate

If there is a mismatch between the framerate of the streaming device (like MiBox) and the TV, then that may cause the Netflix UI error at hand as the app fails to produce the required framerate. Here, setting the HDMI Optimization of the streaming device to the best framerate may resolve the issue. For illustration, we will discuss the process for a MiBox.

1. Launch the MiBox Settings and open Developer Options. If no developer options are shown, a user may enable developer options on the MiBox. 

   

2. Now select General and open HDMI Optimization.
3. Then set it to Best Framerate and restart the MiBox.
4. Upon restart, launch the Netflix app and check if the UI 800 3 error is cleared.
5. If that did not work and the issue is occurring on a streaming device (like Roku), then check if removing the Netflix channel from Roku, restarting the device, and re-adding the Netflix channel clears the UI error.

Disable the Quick Start/Quick Boot Feature of the Device

Modern devices are equipped with a Fast Startup/Quick Start/ Quick Boot feature. This feature reduces the boot time of a device but if the feature “overlooks” a resource essential for the Netflix app, then that may cause the UI error under discussion as the app fails to access the device resources overlooked by the feature. In this case, disabling the Quick Boot/ Quick Start feature of the device may solve the problem. For illustration, we will go through the process of disabling the QuickStart feature of an LG TV.

1. Launch LG TV Settings and select All Settings.
2. Now steer to General and then disable QuickStart (or QuickStart+) by toggling the switch to the off position.

4. Now wait for a minute and afterward, reconnect the device’s power cable to the power source.
5. Then, power on the LG TV and afterward, launch Netflix to check if it is clear of the error UI-800-3.

Update the Device’s Firmware to the Latest Build

You may encounter the UI 800 3 error on Netflix if the device’s firmware (a TV, Mi-Box, Roku device, etc.) is outdated as it may cause incompatibility between the device and the Netflix app. In this context, updating the device’s firmware to the latest build may clear the error. For illustration, we will discuss the process to update the firmware of an LG TV.

1. Launch LG TV Settings and select All Settings.
2. Now steer to the General tab and open About This TV.
3. Then enable Allow Automatic Updates and afterward, click on the Check for Updates.

   

4. If an LG TV firmware update is available, install the update by following the on-screen instructions. A user may have to make sure to keep the TV powered on during the update to avoid the possible corruption of the TV’s firmware. 
5. Once the firmware of the LG TV is updated, restart the TV and upon restart, launch the Netflix app to check if it is clear of the UI-800-3 error.

Try Another Network

A user may encounter the Netflix error UI-800-3 if the ISP is hindering the traffic between the device and Netflix servers. Due to this ISP interference, the data packets may fail to parse by the Netflix app or its servers. Here, trying another network on the device may clear the Netflix error at hand.

1. Close the Netflix app and disconnect the system/device (like a TV) from the current network.
2. Now connect to another network (like a mobile phone’s hotspot) and launch Netflix to check if it is clear of UI-800-3 error.

   

3. If not, check if re-logging into the Netflix app on the newly connected network clears the error.

Reset the Device to the Factory Defaults

The Netflix app may show the UI 800 3 error if the device’s firmware is corrupt and due to this corruption, the app fails to access essential device resources. Here, resetting the device to its factory defaults may clear the Netflix error. For elucidation, we will discuss the process of resetting an LG TV to the factory defaults.  

1. Launch Settings of the LG TV and select All Settings.
2. Now head to the General tab and click on Reset to Initial Settings.

   

3. Then confirm to reset the LG TV to the factory defaults and wait till the reset process completes.
4. Once done, the TV will restart, and then launch (some users may have to install the Netflix app) the Netflix app to check if it’s clear of the error.

If none of the above worked, then a user may use the Netflix addon of Kodi (if supported) to watch Netflix. In the case of a TV or streaming device, a user may use the mobile app of Netflix (by sideloading it) or may try an older version of the Netflix app.
