The iPhone XR was a previous generation model, and there were various screen protectors available from different manufacturers, including official ones from Apple.

To find the original or premium screen protector for the iPhone XR, you can visit the official Apple website or authorized Apple retailers. They should have a selection of certified accessories, including screen protectors, that are specifically designed for the iPhone XR.

When choosing a screen protector, consider the following factors:

1. Material: Look for high-quality materials such as tempered glass or military-grade film for optimal protection.

2. Compatibility: Ensure that the screen protector is designed specifically for the iPhone XR to fit its display dimensions and features accurately.

3. Reviews: Check customer reviews and ratings to see what other users think about the product's quality and ease of installation.

4. Installation: Some screen protectors can be tricky to apply correctly, so you may want to look for ones that come with installation tools or have a straightforward application process.

5. Warranty: Check if the screen protector comes with a warranty against defects or premature damage.

Since the iPhone XR is a bit older, availability of original screen protectors from Apple may be limited. However, there are still reputable third-party brands that offer high-quality screen protectors for the iPhone XR.

Remember to verify the authenticity of the product and consider customer reviews to ensure you're getting a genuine and reliable screen protector for your iPhone XR. Always purchase from authorized retailers or official channels to avoid counterfeit or low-quality products.
