Hi! I’m Daniel. I understand that you're having trouble opening sites and videos on your Xiaomi device using UC Browser. Let's work together to get that fixed.

To start, a few quick questions to better understand the issue:
- Are you seeing any error messages when trying to open sites or play videos?
- Is this happening on all websites or just specific ones?
- Have you tried other browsers on your phone? Do they work fine?
- Are you connected via Wi-Fi or mobile data? Sometimes network issues can cause loading problems.

Meanwhile, here’s a step-by-step guide to troubleshoot this:

1. Check Internet Connection
Make sure your internet connection is stable. Try switching between Wi-Fi and mobile data to see if the issue persists.

2. Clear UC Browser Cache and Data
Over time, cached data can cause loading problems.
- Go to Settings > Apps > UC Browser > Storage.
- Tap "Clear Cache" and "Clear Data."
Then reopen UC Browser and try again.

3. Update UC Browser
Ensure you’re using the latest version of UC Browser as updates fix bugs. Visit the Google Play Store, search for UC Browser, and update if available.

4. Check Video and Site Permissions
In UC Browser's settings, look for permissions to ensure it can access storage and network.

5. Disable Data Saving or Ad-block
UC Browser sometimes compresses data via its servers which can interfere with videos or sites. Disable any data-saving or ad-block features inside the browser settings.

6. Try Reinstalling UC Browser
Uninstall UC Browser completely and reinstall it fresh from the Google Play Store.

If after these steps you still can’t open sites or videos, there could be a deeper network or server-side issue, or certain sites may have restrictions affecting UC Browser compatibility.

Please let me know what you observe with these steps, and if there are any error messages. That way, I can help you further or suggest alternatives!

Are you satisfied with these initial suggestions?

How can update UC browser

Thanks for asking about updating UC Browser! Since you’re on a Xiaomi device with Android 10, here’s a simple way to update UC Browser:

1. Open the Google Play Store app on your phone.

2. In the search bar, type "UC Browser" and tap on it from the results. You can also directly visit the UC Browser page here: UC Browser on Google Play Store

3. If an update is available, you will see an "Update" button. Tap it to download and install the latest version.

4. If you only see an "Open" button, that means you already have the latest version installed.

If for any reason the Play Store doesn't show an update or if UC Browser was removed from the Play Store, you can update by downloading the latest APK directly from UC Browser’s official website. To do this safely:

- Go to UC Browser’s official site (like ucbrowser.io) and look for the latest Android version to download.

- Before installing, ensure that your device allows installations from “unknown sources” by going to Settings > Security and enabling the option temporarily.

- Download and install the APK, then disable the “unknown sources” option again for security.

Give these steps a try and let me know if you run into any issues during the update process! Are you satisfied with this solution?
