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.
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.
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.

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.

For illustration, we will discuss the process to update the firmware of an LG TV.
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.
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. 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.
